Title: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 03/01/07 09:32 AM
I'll use this thread to document the process of removing the Intermediate Steering Shaft (old version) and using the GM Lubrication Kit, for those looking for it.

For starters, here is the kit with contents, and the instructions page:

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 03/01/07 09:33 AM
The following pictures identify the lower portion of the shaft, in the engine compartment.  Tools required to remove this end - 15mm socket and/or wrench.

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 03/01/07 09:34 AM
Next, we'll show the upper end of the shaft, under the dash.  Same tools required to remove bolt at this end.  However, post following this will detail something that aids in removal.

Having a Z66 with power pedals, the accellerator pedal assembly is large, perhaps larger than a non-power.  Removing this assembly provides ample room to detach the shaft and remove it from the vehicle, pulling it out from under the dash.  Tools required:  10mm socket, extension, universal joint helpful.  2 nuts hold the pedal assembly on studs attached to the firewall.

Once the shaft is pulled out, this is what it looks like (compressed)

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 03/01/07 09:38 AM
Instructions inform you that the spacer in the lower end of the shaft is to be removed using needlenose pliers.  Be warned, this is not necessarily easy, mine was very tight.

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 03/01/07 09:40 AM
Once the spacer is removed, the instructions advise to compress the shaft.  Inject the entire contents of the syringe in to the shaft in the end that you removed the spacer from.

Once all lube is in the shaft, install the plug and tighten wing nut completely.  Then you get to exercise your shaft by expanding and compressing it several times to distribute the lubricant.  You should start to see a splined grease exit pattern from the upper end of the shaft collar.  Instructions suggest that you work the shaft until approximately 1/2" (13mm) of lubricant is exposed.

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 03/01/07 09:41 AM
Once the shaft is lubed to specs, installation is the reverse of removal.  Install the shaft from underneath the dash, secure upper end to steering column and tighten bolt.  Reinstall pedal (of removed) and tighten 2 nuts.  Insert lower end of shaft in upper end of next shaft, install bolt and tighten.

Drive a truck that feels new again.

Total time involved, start to finish, for me (including time to take pictures):

25 minutes.

This is really a zero-beer repair in terms of overall time and difficulty :)
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 03/01/07 09:42 AM
Installing the updated shaft would use the same processes for shaft removal and reinstallation, the lubrication steps are skipped.

I read somewhere that you had to keep the steering wheel stationary. Did you use anything special to do this?

What is the correlation of having a Z66 with power pedals? Is something different if you have a Z71 with power pedals? How about if I still have winter air in my tires  ??? Or if I have a green Z66 with power pedals  :laugh:

I was just pointing out that mine was a Z66 with power pedals, vs. a non-power pedal equipped Av.

Common sense :)

One option is the seatbelt.  Run the seat forward, wrap the belt around the wheel, latch belt, move seat back to tighten.

So the difference is you have power pedals. Not that you have a Z66 with power pedals. The Z66 is irrelevant or are the Z66's with power pedals different than a Z71 with power pedals? Not trying to be a D&%k.  :A:

No, only difference are power pedals vs. non-power pedals.  Power pedals make for a more contortionistic installation.

You're just over-reading.

There's no difference between Z66 and Z71 pedals.

Actually your over writing. Simply stating you had power pedals would have been sufficient.

Anyway..nice write up..where was it when I lubed my shaft a few years ago  ???

silly question, but what is the reason that you have to do this? I just got a squeking noise when I turn the wheel.  Is that what you have to do to make that go away?

thank Doug for the write up and pics, very nice :thumbsup:

The lube kit was fix #2 from GM for the loose intermediate steering shaft.  It's not a squeak-related cure.

I have a question about this replacement.

I have a 2003 Z71 1500 that I bought used.  Lately, there's been a low pitch moaning noise when I make slow turns to either direction.  I'm wondering if it is related to this issue and I need the replacement or just have it greased.  The same type thing happened to a 2003 Tahoe I used to own and the dealership said they pumped the steering column full of grease and it corrected the problem.

Any ideas?
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: ygmn on 08/29/07 11:05 AM
moaning?  like power steering pump might be low on fluid?

Post by: wakebdr on 08/29/07 11:43 AM
moaning?  like power steering pump might be low on fluid?

Well, it's hard to describe a sound in words.  I don't know what it sounds like when a power steering pump is low on fluid, though.

It kind of sounds like the sound you hear sometimes when you barely press your brakes and you get that low pitch moaning sound.

Man it's really hard to put sounds into written words.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: ygmn on 08/29/07 11:46 AM
go out..

turn wheel all the way to one side and listen....

the noise you here is PS pump building pressure going over relief valve..
sound similar?
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: wakebdr on 08/29/07 07:51 PM
No, that doesn't sound anything like it.  That sounds more like pressure being released, this is a low pitch moaning...maybe imagine a whale sound...but more "automotivey" sounding.

Does anybody know if you replace the shaft is that a permanent fix? I ask because Summit Racing has a performance on for lifted vehicles and larger tires, it cost $227.00. Does anyone know what the stack one costs?

OK, reading some more threads on here gave me a suggestion of a way to describe the sound it makes.  It sounds almost like a tugboat horn. 

I checked my power steering fluid today.  It was slightly low, so I added some to bring it up to the full mark.

Seeing as it was only slightly low, I don't think that was the issue.

Well I just did the change over. It went good except I did not turn the steering wheel so I could access the bolts easier. I never said I was the brightest person on this site. Once I figured out that it was pretty easy. I did apply a little grease to the shaft so I could get it back into the steering port. Thank you for the instructions. Now I am going to purchase the recharge kit and get the old one prepped for when this one goes out. The only tool you need is a 15MM socket for this job. Also be sure to remove the bolt side on the engines side and the nut side under the dash. This was the only issue I could see.

Yeah, without power pedals, it really appears to be a piece of cake.  Probably 10 minutes for me.

If only I could work with wood as well as with mechanical stuff.

According to a GM dealership, they no longer offer the lubrication kit.   They did tell me that the intermediate steering shaft has been redesigned with a larger inner core to prevent the problems that have been occurring in the past.   I just replaced mine today for the second time in three years.   Only time will tell if the new replacement will hold up.   I purchased the new shaft for $70. 00.   It took me around 20-25 minutes to replace.

We used to brush white grease on the shaft and push it in on the GMT800 Silverado/Sierra HD. Pushed it in so it wouldn't catch on anything when they dropped the body on the engine/chassis.

When you glob enough white grease on and push it in some of the grease goes right up inside and stays. You'd still have to disconnect the lower part of the ISS under the hood so you could compress it, maybe add more white grease and repeat a few times, then reconnect it. Might work and would take little effort.

My apologies.  For some reason I thought the procedure detailed replacing the shaft with the new one.  Again, I apologize.

Now, since the lube kit is discontinued, what is everyone using the lube the shaft?  I've seen white grease mentioned so far, but nothing else.

Also, do you need jack stands to perform this procedure or will ramps suffice?
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: Shanes 02 Avalanche on 10/24/07 11:16 AM
You don't need either. Just open the hood and unbolt the bottom of the ISS. Then go up under the dash above the pedals and unbolt the top of the ISS. It is just that simple.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: DougD on 10/24/07 01:49 PM
The lube kit still exists in some dealer stocks.

I'm accumulating some that I can pass along to folks, as well as keeping a small private reserve.

I don't have any penetrating oil, but I sprayed some WD-40 on it and tapped it with a hammer.  That worked for me before when the dealer put the oil drain plug back in with an impact wrench.

Nope.  Although it'd make more sense to have actually posted in that thread.

Remove the top end as well and then work to pull it towards the interior.

Post by: STOBOTZ on 12/20/07 09:53 AM
Well, I have pulled. . .  from both sides, in and out. The prob of pulling from inside (under dash) is the shaft only expands.   There is not enough room to pull out from the lower shaft.   :E:

If it's that bound up, then hit the lower end with some penetrating oil - I can't recomment PB Blaster highly enough.

I finally got the new ISS installed and now I am glad I did.  After I installed it this morning and running errands this afternoon the avalanche drives like new!

I did have issues trying to remove the upper from the lower. . . murphy's law.  But now that it is in and driving like new I can say that this is well worth it.

Is there a difference in the shafts for a 2005 and a 2006?I couldn't get the part to come up on GM Parts Direct for the 2005 but it did for the 2006.Just want to be sure before I spend 60 bucks on something I can't use.

I finally got my ISS out the other day and lubed it up.  I spent about 20 minutes or so slathering grease on it and working the shaft out to spread the grease.  It feels better now, but I may still order the replacement shaft.  However, I think a new instrument cluster has priority over the ISS right now.

Well I haven't even owned mine for a week and think I've been bitten by this Intermediate Shaft bug.

Felt it on the way home, thinking something might not of been greased, but did that, then found this site and there you have it.

Dealer I bought it from has a warranty, but its over 100 miles one way, plus its a dodge dealer, so I hate to drive that far for them to check it, then have to go back for them to order the part so on so on.

So I guess I probably  should order one from gm direct for 66 and save myself the trouble.

Thanks all ....great site

After reading your very informative post on how to grease the shaft I decided to contact GM since my vehicle is out of warranty.   I was told that they had a fix for it by replacing it with a different shaft.   Since mine had been greased once during warranty by the dealer that they should replace it without cost.   They did it today.   You may also qualify.

This is kind of a popular question with alot of different answers.

What I've learned is, if your the orginal owner chances are pretty good that you can get it replaced from the dealer.

If your the 2nd owner (like I am) chances are your going to have to suck it up and pay for it.

But by all means call your dealer and ask, worst they can say is no.

I just replaced my rattling part (15000 miles) on a Z66 and bought  its replacement version  from GM  Parts Direct for about $55.00 and changed it myself in about 45 minutes--Lock down the steering wheel with bungee cord, remove the gas pedal  using ( 1/4 inch drive and extension) (adjustable pedals here)  I am more satisified by doing it myself!   You can do it too!!! Also got rid of the rattles through the steering wheel- Thought it was my Hotchkis bars for a minute there... ::)

We are not alone hundreds of thousands of trucks like this platform are getting them done!

Post by: avi0922 on 03/06/08 03:40 PM
also another good tip to getting the shaft out is to remove the boot on the firewall it has 3 aluminum type nuts thats it. pull the whole thing out(of course after unboltiing the bolts on the shaft) slide the new shaft in the boot and install it saved me time from having to undo the electric pedals...

ntermediate shaft P/N 19153614 has been designed to replace previous designed dampened and non-dampened Intermediate shafts.

that is the part i ordered from gm parts direct, so i do not need to lube this before i install. i will be trying this in the morning possibly, so any last minute hints or tips would be appreciated. so is this down in the engine bay or upper part toward the firewall ?

O/K, I have the lube kit and looking at my 03 Z71 I don't see how you lube this, unless once off / apart it is obvious.

The reason I mention this is at the same time I do this lube I am doing the power steering sensor, hope that name is right.  GM # 26104070.  I don't have the clunk in my steering, the lube is just a precaution, but I do have the steering pulling left & right at times, like you are getting into ruts in the road, I am told that problem is this sensor going bad.  It is supposed to go at the base of the shaft in the interior, so figured I would do the lube & sensor at the same time.

Any thoughts / opinions on this?

Yes, I have LOOKED, my point was the steering sensor may be part of the odd feel in the steering, maybe the lube + the steering sensor is a good combination to do all at the same time.

So, I do appreciate your post / pictures, but "Have you LOOKED at my post"?  ::) :P :wave:

Have the tires straight.  Use the seatbelt or a steering wheel locking pin to keep it from moving.
Wrapping the seatbelt around the steering will should be sufficient.

Oh well, not to be a PITA here, but you left out my words "unless once apart it is obvious".  I meant in looking at the shaft while still on the truck I did not see an obvious lube point, so I asked what I thought was a simple question.  Your pictures are clear and very helpful, and since some have questioned about some trucks maybe having a different shaft I was trying to make sure before pulling the shaft off.

Have a good day & thanks for the helpful post.

And again, had you READ the thread, LOOKED at the pictures, and even looked at the instructions in your kit, you'd see EXACTLY how to lube it - nothing that's not obvious in the process.

The instructions and thread detail how to lube the shaft, there should be no "gray area" about looking for some external lube point on the shaft ::)

Remove the underhood bolt.  Remove the acelerator pedal assembly if applicable- as mentioned, a 1/4" drive with long extension and a universal joint makes this easy.  Then find the best position to work on the inner end and lock the wheel in that position.  It's just important that the wheel is not turned once the shaft is removed.  Slide the shaft toward the firewall to remove the inner end from the steering column.  Then pull the shaft through the firewall into the vehicle.

Popping isn't the ISS, it's a body mount issue.  Search for popping and turning

Post by: Shanes 02 Avalanche on 03/16/08 06:32 PM
I just left my steering wheel alone, I found it was easier to remove the ISS if the steering wheel was free to move about. Just remember to look at the steering wheel to make sure it is straight when you line up the new ISS.

  Wanted to give an update on what dealers may do regarding this issue:

Took mine to local dealer that I use for service in Northern Kentucky, and when I dropped it off I noted the TSB number along with the steering problem. When I called back they said they took care of the issue because GM was now covering that repair up to 60,000 miles. Take that for what it's worth. Oh, and I am the original ownder. Av has 32,000 miles and is an '04 Z66.

On a side note, I want to thank every one here for their constant source of information. As a collective, this is one fantastic little society. It's good to know that I have a single source to reference when I have an issue. Thanks to all. :thumbsup:

When was the last time you lubed the front end? Also check you shock mounts, you could have a broken bushing. It is basically time to get the front of the Av up on stands and have a looks see. I know when I lubed my chassis after doing the ISS it felt a whole lot better and solid.

Good Luck

There are several possibilities.  Did you do a search on this site for "popping". 

Your steering shaft would have had to be replaced sooner or later.

I have a 2002 with 100,000 miles, still going strong.  About four months ago my dealer replaced the old shaft with the new part and I've had zero problems since.  One more thing: it cost me nothing because they covered as a "goodwill warranty" as a known defect (but not a recall).  It might be worth a shot for those that haven't already replaced it or keep lubricating the old one over and over.

I just recently did this on my 04 and it was not too bad at all. The hardest part for me was getting the pedal assembly off for better access (I have power pedals). The part cost about $60 shipped and probably took my about 45-60 minutes to install.

Big difference after replacing it as well.

Just installed my new ISS from GMPARTSDIRECT.  The creaking I experienced when turning the wheel is gone!!!  Thanks Doug for the OP - it was very helpful.

Problems I experienced:  the new shaft was slightly larger than the old one or possibly the lower shaft was slightly deformed from the compression of the bolt, I dunno, but whatever the reason I had a heck of a time getting the new shaft to slip inside the lower shaft.  Finally had to grip the ISS just above the taper with Channel-Locks and hit the pliers with a hammer (lightly) to seat it and get the bolt holes to align.

Also the old shaft has splines and was well greased - it did not appear to have any slop or kinking in the universal joint so I am at a loss as to what is actually wrong with it that would cause that horrible noise...anyone know what the defect is exactly?

Thanks again for Doug's and everyone else's posts on this topic.

I'm replacing mine tomorrow, but I have 2 questions... :help:

1. Do I have to remove the "boot off of the firewall that the shaft goes through????

2. Can I just pull the shaft through the boot once the shaft is disconected???? (which way? toward the engine or toward the inside of truck???)

 THANKS  :wave:
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: SCOTTS on 08/11/08 10:21 AM
I did not remove the boot from the firewall.  Once the bolts have been removed and the ISS is slid up and out of the female portion of the lower shaft you can tilt the ISS horizontal and pull it through the boot from under the dash (into the cabin).

Note: as with installation of the new one, mine was tight and I had to force it out with a flat screwdriver held against the taper in the shaft.  After a couple taps from a hammer it fell free.

Good luck...

Mine was replaced a bit over a year ago by GM in my '03 Tahoe...supposedly with the new and improved shaft-after having been replaced a year or so before that as well.  However, it's back to it's old shenanigans...
(had same issues with '02)

I'm going to have to learn how to deal with this, so I'll be perusing this thread to learn how to 'lube' the shaft...

Geez that sounds so bad!
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: SCOTTS on 08/11/08 11:22 AM
My thought is since you have to remove shaft to lube it you might as well buy the replacement and put a new one back in...they are not that expensive - $64 incl. shipping from GMPARTSDIRECT.COM

It wouldn't kill me to have to address this issue every 1-2 years.  I hope it is a permanent fix but if not I'll just order a new one and get my hands dirty again...

You will have to remove the shaft to lube it.  So the same tools will be required.  :)

FYI: I just read through the receipts I have on my truck from dealer visits and it appears the ISS was "fixed" with the lube kit twice before so it's doubtful that the lube job will do much more than delay the inevitable.

Thanks Doug for an exceptional write up and great pictures.  I recently had the dreaded steering clunk return on my 04 Avalanche (now at 37K miles).  When the steering clunk initially appeared, the dealer lubed the steering shaft (under warranty) in 12/06 (29K miles) and it was fine until about a month ago.

After reading TBS #00-02-35-003M describing the replacement of the ISS (to resolve the clunk noise), I was somewhat reluctant to tackle this job myself.  But after reading your great write-up - no problemo!

I will try to first try to have Chevy do it on their dime, if not I'll do it myself.  The problem is local car dealers, including my favorite Chevy dealer, have closed down due to the economy and Wall Street debacle.  And I hate to take my AV to someone I don't know or trust.  So having the option to do it myself is a big comfort.

Many thanks.

I have lubed mine twice in 107K. I just replaced the ISS in my Olds Aurora with 56K on her. It was done twice before by the previous owner by GM but both times previous to 06 when they came out with a revised shaft. Now I have the new unit. Both vehicles are relatively easy to change them and will replace the AV with a new one when it happens again  :A:

In fact the Aurora was easier, no power pedals in the way  :A:

Hi all I tried today to remove it and I had no luck I took off gas pedal bracket and I couldnt get the shaft out either way it would come up so far and then jam against steering colar with the plastic ring on it (under dash). The end inside the motor is kinda rusty where the bolt is. It looked like the shaft part inside the tube was going to come out and thats it.Put it back together and will try another time why couldnt GM put a damm grease fitting on the tube part and then all we would have to do is grease it externally? Any help would be great thanks guys :thumbdown:

I expected it to be a PITA compared to the AV but it was not. With the drivers wheel off and a long extension the bolt was easy to get to. And from the inside even easier to remove the bolt and pull the shaft out. Hopefully with the new design I wont have to do it again, at least not on the Aurora  :A:

I just got my updated ISS from gmpartsdirect and looking at it it doesnt seem very well greased. There is no grease ring when compressing it and decompressing and not much grease if you touch the shaft portion that should have grease. Should i just put it in a see what happens or do i need to grease this thing first?

If you are having trouble getting the shaft out try making sure it is compressed all the way when bringing thru the steering hole. I did mine in about 15 minutes and did not need to remove my gas pedal. Make sure you did not miss anything in the Awesome pictures posted previously. I have got pretty good at fixing my own Av. The Fuel pump was easy, once I got the nerve up to cut the AV. It made it a lot easier then dropping the tank. My Av has not been to a shop about 3 years.

Post by: butterfingarz on 01/13/09 01:47 PM
shanes you may be able to respond to this one since you have a 2002 as well but in the picture pedal 3/4 in my truck it looks like the ISS is closer to that metal bracket than it is in the picture in a 03+. I cant really get a wrench back in there in between the channel of the metal brace if that makes sense also the other side of the bolt is about a 12mm and is a 12 sided nut which cannot be used to unbolt because it will just strip the nut.

Outstanding write up and instructions  :thumbsup:.

After reading this thread I decided I would do a replacement instead of repacking.

I have the power pedals and would suggest removing the boot on the firewall and raising the pedals all the way up for easier (at least for me) removal and installation.

Awesome post!  :thumbsup:  Thanks for the tips! I installed mine today. You can get the aftermarket ISS for $120 at NAPA Canada. Don't bother with GM Parts Direct...what a rip off...$165 for us Canucks.

I definitely recommend taking the boot off of the firewall. It would have been impossible to wiggle that sucker out of there if I hadn't. It also makes taking the ISS out of the vehilcle easier (straight out from under the hood instead of through the firewall and into the cab.

I bought this 2004 Av a few weeks ago. I noticed as I took the old ISS out that it has been relubricated a number of times. White grease all over the dang place. Hopefully this aftermarket one holds up better.

Thanks again for the tips and photos. This is an awesome sight. Saved me about $100!

Just purchased a 2004 z71 in great shape but I am pretty sure it needs a steering shaft. Previous owners said the dealer greased it once.

I called the dealer here in Canada where I live and they told me 365 CAD bucks for the shaft. I cant believe that. Is this really what they cost at the dealer?

Just ordered the Dorman part locally for 120 bucks CAD.

This is the part I ordered = DORMAN Part # 425176 - hope it is the right one

Took me about 20 minutes. Was easy. I have the power pedals so instead of undoing them I took the firewall boot off from the outside 3 small easy to get off 10mm nuts and the whole shaft comes out into the engine side.

Now the steering wheel is solid and that little clunking problem is gone. Drives like a new truck. I would never of know this without this forum! Thanks so much!

Still have a little squeak somewhere in the front end. Original Shocks, 2004 with 113,000KM (70,000 Miles) So maybe those are the culprit.

Oh I highly recommend the fuel Pump mod. It makes changing the Fuel pump a 10 minute job, everytime.

Replaced with Dorman 425176. Mine has ~ 60K mi.
Boot nuts are definitely the way to go. Messing w/ the power pedals takes longer & is a PITA.
Only issue I had was that the dealer (apparently in an effort to solve my clunking complaints) has crankled hard on the engine compartment side bolt. Made it really hard to get old shaft out & new one in. Had to do the 'hit the vicegrips w/a hammer technique'.

Thanks to all of the previous posters for the info !

I had a shop tell me that they solved this by filling the shaft with RTV silicone and they have never had a problem. I guess the silicone cushions the shaft and stops the rattle.

Ok, Ive read almost this entire thread, Great DIY Instructs doug!!

My problem isnt a clunk, its a squeal noise in the cold mornings when I turn the steering wheel. It lasts until the truck is warmed up.

I tried shooting some WD-40 where the ISS goes thru the Firewall from the Cabin-side and the sound is still there.

Anyone ever had this sound?

Thanks - David
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation

That would most likely be your Power steering pump. Check your fluid leve.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 10/28/09 11:53 AM
This is for sure inside the cabin. Ive done power steering pumps before.

This sound is definitely coming from under the dash, its not the horrible loud power steering sound...I know that sound all to well. Opening the hood and turning the steering wheel produces no sound from the PS pump.

Basically, this sound is just irritaing, and sounds like if rubber is rubbing against metal. If I have the radio on at low levels you cant hear it. Its not that loud, its just irritating.

Im certain its a gromet or bushing for the Intermediate shaft, the boot thru the FW, or inside the tilt...

Just hoping someone else has had it, so I dont have to pull the entire unti out. But trust me..if needs be, I will do that too.

Thanks though for the reply.

Post by: mattie 03 on 10/29/09 01:41 AM
Last week I put a 3/4 of a tube of clear rtv silicone in the intermediate steering shaft instead of greasing it. I had replaced the old steering shaft with the new redesigned shaft and less than a year later it started the same dang clunking noise and the steering felt loose almost like a bad ball joint or bad inner tie rod. The silicone has quieted the noise and the steering is solid as a rock!!! Honestly it feels just like it did when I drove it off the lot new. Give this a try. It's a good fix. :thumbsup:
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 10/29/09 09:41 AM
The only thing with doing the Silicone RTV is that if it bonds to both the inner and outer ISS shafts, it wont allow the up-down play needed for going over large bumps, rocks, pot holes etc etc.

So, rather than the shaft compressing, it will try to shove the steering wheel up, possibly damaging the dash and/or the small u-joints on the ISS shafts.

If the silicone doesnt bond to the shafts, because there is already grease in it, and the silicone just cures and prevents play in the shaft, then it actually might be a good fix.

How can we AV owners know which it is?

Well...Id suggest, since its really only a 30-minute +/- removal - have Mattie 03 or one of the other AV owners who have done the Silicne thing, take the ISS out after 1 month and see if it still compresses in-out or not.

If it does...then Id have to say, its not a bad idea. Its not  a high-speed or high-temp mechanical part, it just gets a lot of moment-force/torque on it, and silicone dould really cushion that force.

Post by: Dads04Z71 on 10/29/09 10:05 AM
The initial GM Service Bulletin/Fix for this problem was to lubricate the shaft.  This worked for awhile (in my case several months) but the knock/clunk noise came back.

Then GM issued a new Service Bulletin advising shaft replacement.  In my case, the dealer split half the labor/part cost with me.

I no longer have either Service Bulletin number at my finger tips but if someone wants them, I pretty sure I can dig them up.

Mine is not clunking but my steering is floating really bad. I thought it was shocks or bushings. So I replaced all of them and i still have the problem. Everytime I drive and my tires hit any of the ruts on the interstate or roads my Av feels like it is on ice. I replaced my shaft last year about 40k miles ago. Look like it is time to do it again.

But you get it up in the wind and grooved pavement and it sucks. I was thinking maybe my 285/70/17's were the cause. It started out as just barely noticeable, then just progressively got worse. My front shocks were completely worn out when I took them off. Thinking about it I replaced my steering shaft back in 07. So it has a lot of miles on it.

Ok so about 1250 miles....PLEASE repost to this thread or the Forums later and give us an update in the future.

Ive always had doubts the dealers install the real re-designed parts...would you be willing to post the part number from your invoice that they show?

Thanks

Gladly - Part # from invoice is 19153614

 :thumbsup: :B:

That IS the new/updated P/N: 19153614

Here is a good link on a complete install proceedure - apparently there is an access hole in the steering column under-side that allows you to lock the steering wheel into place, since us AV owners down have SW locks. This might help some folk, just FWI

 :thumbsup: Thank you Chase04 from that forum!

Whats bothers me now, is that do you think its possible the dealers are putting the new P/N on the invoice, but actually working thru their inventory of the old P/N ???????????????

I mean...they would NEVER do that right? Naaaaaaah...Never.

How can we tell if this has happened to us? Well, if anyone here has had a new one installed, and it fails (Ive read at least 3 or 4 posts like this) - Remove the ISS and see if it can be taken apart...the new P/N cannot be taken apart to be Lubbed...the old one can.

Voila! - Luckily mine is still fairly good, but Im 99% certain I will need one here in the next year. I will make sure Ive got the REAL P/N: 19153614

Another reason why I try and do all my own work. I do not trust dealers.

I used to do all my work on cars and trucks but age has limited my mobility and motivation.  Also, without shop manuals and the required specialty tools, the complexity is getting past my former abilities.  When I was younger I and my friends used to modify and drag big iron - like 56-57 Oldsmobile's, 389 Pontiacs with Tri-power and dual quad 425 Buicks.  Then there were the 409 dual quad Chevies with 4 speeds.  We could retime and recurve our distributors, change out the carbs and/or rejet them.  Holly double pumpers were popular.  We would regear the rear end in a couple of hours.  All that was needed was a good set of ratchets, wrenches, timing light, dwell/tach and torque wrench and a good set of ears (tune by the way the exhaust sounded).

Enough history - the best part of the Avalanche Club is its members and the insight the members provide (and share) in fixing and learning about our vehicles.

Didn't mean to rattle on.

I know what you mean by only needed a good set of tools a know what to listen for. I use to be able to drive a car and know what was wrong with it. installing a set of triple carbs on a 240Z and just by listening. I could adjust the mixture of each carb. I could drop a tranny and install a clutch in a couple hours. But as you, my age and disabilities are getting the best of me. I try to do all I can myself to save money.

Basically I hate paying someone $85.00 an hour, to do something I can do. The only things i get done at a shop are the tranny and alignment.

I fix the squeaky noise the steering wheel had in mornings.

Removed the boot from the firewall, greased up the ISS, put the boot back on, and no more sound.

Now that the sound is gone, I think I can hear the dreaded low clunk feeling of the ISS itself.

Probably need to do that in a few months.  :E:

Drag. Youd think with how sturdy and tough the rest of the truck is built, they could friggin make an ISS that lasted 100K.

Oh well.

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: Shanes 02 Avalanche on 11/11/09 11:46 AM
My last ISS is the new one and lasted just over 40k, my first one lasted over 100k. So I don't think the upgrade is worth a dam, that is why I went with the Dorman. I have not yet installed it, just being Lazy and it is in the 30's here. I do like the looks of the Dorman over the GM. The blue silicone grease looks a lot better then the white grease in GM's product. I am hoping to install it Saturday. I cannot do it during the week because i have to drive the kids to and from school and cannot afford for something to go wrong where my Av is down. I know it is a 20 minute job, but if anything goes wrong I am done. I will let you know what i think after I install it. I will be driving 900 miles one way to Cali on the 21st for T-Day. That will be a good break in period.

Thanks for the info 66.  Ive been wondering if the new redesigned shafts were going bad, and you answered that question.

I qill probably pick up the doorman one and install it in the next few weeks. Mine is just clunking a little, not bad, but its annoying.

After I got rid of tghe squeaking sound, the clunking was easy to heard...HAHA - Fix one thing only to discover another,

At least the ISS is a relatively cheap and easy fix.

Rock Auto says that the 19153614 translates to 425-176.  The box has a Dorman sticker and the 425-176 PN on it and the shaft itself is marked 425-176.

Is 19153614 GM's part number and 425-176 Dorman's Part Number?

19153614 is the GM number.

RockAuto mostly sells aftermarket, so the 425-176 is another suppliers part number. If its Dorman, I dont know, cuz I havnt looked at the Dorman yet. But its certain the 191...is the Genuine GM re-designed Shaft P/N.

OK it took my less then 20 minutes to do the install. I even took pictures. Here are a couple pics. One is of the GM ISS the other 2 are the Dorman. From comparing them side by side, the Dorman looks a lot stronger and better built. It has a grove in the side of it with an allen set screw. I am guessing the set screw is to adjust the tension on the slide grove.
The GM ISS has just the round bar that slides. As for install it was way beyond easy. I do recommend that you spray a little WD40 on the end that connects in the engine compartment. It makes the job so much more easier.

You might be able to open the full-size image of the dorman shaft - if you didnt resize the original file, and then crop the area of the screw and groove, then post that one.

Or, if you have a full size image thats not reduced to fit under 100KB for this site, you could send it to me...please :-)

The full size pic will let me see the groove clear enough.

Well, I did a little research today, on other GM truck forums....I will NOT be getting the "new" "redesigned" GM shaft.

Every person on the other forums that posted in 2009 said they have had to replace the new GM shaft within a year.

ALL of them said the Dorman shafts are the way to Go.

THANK GOD, and Thank everyone here for our collective help.

A lot of people with $$$ also said the Borg Shafts were very good...but for $200+...Id replace a dorman 4 times.

Ok, Im not being specific enough - so let me retry :-)

All screws and bolts turn, this causes them to go in or out - adjustment on whatever they press against - This alan screw looks like is might be there to set tension from the outer shaft to the groove on the inner shaft - Or maybe its just there to hold something together? I cant tell.

If that screw turns, and is not locked into place, then it can loosen up over time, but if its factory adjusted, and locked into place with locktite or by deformed thread, then nothing should wear out or loosen.

Im just wondering if its locked into place by dorman, or if anyone tried turning it a little bit just to see if it turns easily.

I know...Im being super-specific now, but Im just curious.  LOL

the set screw is just a "stop" to keep the shaft from over extending, it is not under any tension.

I offered Autozone to price match, but they didnt want to...its a shame, no way in hell Im gunna pay $75+tax, when I can get it for $45/$55 shipping included.

If Summit can make a profit selling it online, Autozone can make a profit selling it from a store...shame.

SirShops: GREAT Pics man!!!! - It really looks like the Delphi shafts are inferior, both in engineering design and in manufacturing.

Plastic splines are just a no brainer....Why would you build a kick-ass truck, thats beefy as heck underneath, and then place a toy part in the steering? Well...at least we know of these little problems, and us bloggers help each other out!

Hey SirShopsalot - I installed my Dorman ISS Yesterday - 20 minutes!! - I noticed the Dorman ISS that was shipped to me didnt extend/compress smooth - very tight actually - was yours this way? Other than that, its a perfect fit.

That Blue stuff is some kind of plastic/nylon and appears to be the material to keep the inner and outer shafts from clanking togeter. I actually couldnt see any grease on the dorman shaft at all.

I added some white lithium grease to the Dorman and worked the shaft for a few minutes (HAHHA), it loosed up a little, but was still hard to compress. Just wondering if yours was the same.

The stock ISS extends and compresses with No effort at all. I kept it just in case.

I sliced my thumb open on the bracket for the power pedals - So everyone else BE CAREFUL!!! - BTW - There is no reson to remove the pedal bracket - I didnt, just remove the boot from the firewall, and the ISS comes out from the engine side without any problem.

Yes, the Dorman was stiff.  I left it alone, figure they would have greased of told me to if it needed it.  :dunno:

Mine took a little longer than 20 minutes, I had to ride my bicycle down to the parts store for some grease to lube up the fire wall boot.

Well everyone...Yesterday driving, I kept feeling a 'popping' / 'clunking' sound, and I could feel it in my steering wheel...as I drove home it got worse  >:(  - Even on a smooth road, the slightest press of the brakes or slightest bump in the road caused the sound. Backing out of the driveway into the road, and It would pop 2-3 times as the shocks went up and down.

I checked to make sure the bolts on the Dorman were torqued, and they were right on. So, I drove around for 15 minutes going over speed bumps, tapping the brakes etc etc. And I determined the new dorman shaft I put in had to be the source of the sound.

So, At 7:00pm I removed the Dorman, and put back in the GM Shaft.

Poping and clunking sound is gone. Completely.

Not only did I not need to replace my ISS, but the Dorman was horrible. I posted on here how tight the shaft was...its did not want to slide in/out easily at all. And when I removed it, I can hold the Dorman in both hands and make it pop by trying to bend it.

Sirshopsalot...are you having any issues?

There is a post about 4-5 pages back in this thread that listed a few dealerships with the lube kit, but that was earlier in 2009. I think for the most part, they are gone - aftermarket stores dont sell the kit.

And from everything Ive read, the lube kit is a very temporary *fix* - once the grease works its way out, the clunking returns - I heard other people say in less than 10K miles.

Im really pissed my dorman Shaft was crap. - Its going back to Summit today, and I will probably get the re-designed GM shaft and plan on replacing it every 30K miles...its a cheap and easy fix.  >:(

Nope I already installed it and the allen is in the steering boot. Sorry about that.

Hey Shanes02:

Was your Dorman ISS really hard to slide in and out?

I removed my Dorman last night because the thing was clunking and poping with the slightest bump in the road or touch of the brakes. Putting the old OEM shaft back on feels like a new truck.

My Dorman shaft from Summit was almost impossible to slide in/out, so I worked it for a while before installing it, but it was still super tight. Over the course of driving it for 1 day it went from a slight clunking similar to my GM ISS, to non-stop popping/clunking by last night.

When I removed the Dorman is still didnt want to slide in/out, but I could notice a smovement of the shafts when flexing them side-side.

Yeah, Mine got so bad by Monday night, I thought there was another problem, like a friggin shock went bad, or a loose suspension part. But it was difitely the ISS Shaft. Non-stop popping sound.

My shaft had the Blue plastic visible, just like your when it was fully extended, but when I say it was tight, I mean I could hardly pull the 2 shafts apart, maybe "Binding" is a better word than Tight. And once I got them extended I had to place my full body weight to get them to slide back in. Im certain what I was hearing was the shaft binding in and out as the suspension/body moved slightly up and down.

At any rate, I re-lubed the stock shaft, and put it back in, and there is no clunking or sound anymopre at all. I know it will only last 10K miles or so, but that will give me time to lok at another dorman, or maybe the new GM shaft.

BTW: It took me 18 minutes to change out the Dorman back to the OEM shaft tmonday night...Ive got it down to an art, including locking the sterering wheel using the seat belt.

Mine is working awesome. I just did a 900 mile drive over all sorts of kind of terrain and had no issues at all. My Dorman was stiff but not bad, I could slide it with out much effort. I am extremely happy with it. My Av rides better then it did when I bought it. The steering feels awesome and firm. When I pulled out the GM ISS it was trashed looking and worm out.
Sorry yours did not work out.

Maybe I got the bad one of the bunch..I saw your GM shaft pics...completely trashed. My GM shaft was just barely beginning to clunk a little bit, which is why I got the Dorman, but after putting it back in, its night and day, so I will drive it until it clunks like this new one did.

It was friggin horrible...like driving a POS for a day..HAHA

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: 12VoltMan on 11/29/09 03:03 PM
Not that I know of.  I had it replaced once at the dealer several years back, bu the clunking noise has returned with a vengance the last year, so I opted to do it myself this time, everything went smooth until I attempted to fit the the new ISS into the lower shaft coupling, which would not even start.  I have since removed the lower shaft in an effort to try to pry out a little more room where it was torqued down, no luck there either.  I actually think I have mishaped the lower unit worse, so my new plan is going to be to replace the lower unit.  I have had trouble finding this part online anywhere other than parts direct?  Any ideas?

Thanks

If the lower shaft was deformed, its very difficult to correct without removing the lower shaft from the PS unit. And you bsically have to re-shape it.

Or, you can grind a TINY - VERY SMALL amount of metal off the new ISS.


Neither is a great solution.

Sorry.

Here it is going on two months and my ISS is just as solid as a new one after putting the silicone in it. It has a little bit of flex when it's removed but very very little.  It doesn't really need much flex or movement to perform correctly. I have climbed over tall curbs, run through pot holes, tall speed bumps, gone out in the woods across small ravines and it still works excellent. It was 75 degrees when I installed it and it worked great. Last week it was 9 degress and it worked equally as well. Honestly guys, if you're looking at buying a new shaft for upwards of $80 to $120 to replace the old worn out clunking shaft, why not try the silicone first and see how it works for you. If it doesn't work then you can buy a new one but the new shaft for me was total waste of money. After just a few months it clunked just like the old one did. The clear RTV silicone cured my problem and I'm very happy with it. Just my own experience and opinion.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 12/29/09 08:32 AM
This makes some logit, since the ISS's slopiness was due to tolerances in size from the inner smaller shaft to the outer shaft.
The question I have, is How did you keep the clear silicone from mixing with the Grease inside the Old ISS? And how did you keep the clear silicone from binding to both the inside and outside shafts ?

Thanks - DK

My Dorman ISS Has been through over 3000 miles of harsh driving and temperatures. I was in Cali for Thanks giving and hit a pot hole at over 75mph. I hit so hard I bent my pitman and idler arms, but my ISS is doing awesome. The temps right now are anywhere from -6 to 25 degrees. And the Dorman was only about $40.00. If the silicone works, do it. If you want to just replace yours, pic up a dorman from Summit racing.

The steering wheel I just leave along and unbolt the ISS from it under the dash. Then you disconnect the bolt holding the ISS in the engine compartment. Then you just do the reverse to install. The only pin I can think of is the bolt in the engine department. You might be over thinking the job.

I move mine to get to the bolts easier. Just don't turn it over. You can move it back and forth since the shaft will only fit either right or 180 out. So if you do not turn the wheel you should be fine. Otherwise do the seatbelt trick. Like i said before, I have done this twice with no issues what so ever.

Post by: arizona-dave on 01/11/10 08:01 AM
The Seat belt think works...very well.

Also - The sterring wheel can move a little bit (less than 1/2 turn) when the shaft is removed - its not critical. There are sensors in the steering wheel and if the wheel gets upside down (the Chevy Wheel can only be in 2 positions) then the sensor will be way off, but your steering wheel would also be upside down. So it would be rather obvious.

Other vehicles have a splined shaft, and so even a slight turning of the steering wheel can make the wheel be off center.

Whoever was talking about Airbags being disabld may have had other issues with their truck, or a bad harness connection somewhere. Airbags are controled thre the ECU and special sensors on the frame of the truck, not thru the steering wheel. The Air bag inside the steering wheel is controlled by a harness under the dash, not the Intermediate Shaft.

move the power seat forward, slip the seatbelt through the steering wheel and buckle it,power the seat back to remove the slack and make it tight, wheel will NOT move.   :thumbsup:

Post by: arizona-dave on 01/11/10 03:43 PM
That Pin is up past that white plastic disk-shaped thing, I tried to get to it, and I got tired of looking....so...after that I take my Bolt off forgetting to lock the steering wheel...the wheel rotates freely, and I then get to remember which way it was - so I take a second look at the wheel and its slightly turned to the left, so I know my steering wheel was upside down.

In any event, I then locked the SW with the seat belt, and all was good.

I ended up having to remove the Dorman I bought because it was Bad, and I re-did the Lub kit on my GM shaft, and all has been well since then.

Dont fear those Airbags too much, its a double-protected impulse system requiring 2 channels of voltage to set them off...youd basically have to short 2 wires at the same time to a live 12-volt wire in order to set it off...not likely.

Have fun! :-)

I've done two shafts now and it's worked out great. Here is what I did. I took the intermediate shaft loose, cycled the shaft by hand several times (that sounds so weird no matter how you word it) wiped all of the grease off it, pulled the small chrome spacer out of the bottom, took a tube of silicone and packed it the shaft full while cycling it to make sure it worked its way down in there, then reinstalled the chrome crush spacer. I then put two or three good shots of silicone into the lower shaft where the two shafts join. Reinstalled the intermediate steering shaft, and made sure all connections are tight, let it set for an hour to make sure it sets up a little and thats it!!

This has just been my experience but for me it has worked very well on the two trucks I've done this same thing to. How to keep any left of grease and silicone separate I'm not sure but the silicone gives the shaft the cusion it needs to keep from clunking just like the grease does with the exception that the silicone does not break down and work it's way down in the shaft to start it clunking again.

The seatbelt through the steering wheel is the way I do mine. Works very well.

One side of it is staked in place. I think it's the nut but no positive. I you can't get one side to turn try the other and will come out pretty easy.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 01/12/10 07:24 AM
I think under the Hood its the Bolt-side which wont turn, and under the dash Its the Nut-Side which wont turn - Cuz they are welded to a metal Tab which prevents it from coming loose (its a safe-guard).

They really cant be tightened to the point where they wont come loose cuz by then it will crush the tubes - and they would come loose anyways.

On the Silicone trick -
Im curious to see how the shaft moves in and out after doing the solicone - if it doesnt move in and out with little pressure, there is posibility of putting stress on the steering wheel bushings and steering box - it might not make a sound, but if the shaft isnt capable of move in/out easily, its gunna force something else to give.

That was the problem with my Dorman shaft - it wouldnt go in/out without a sh!tload of pressure, and it was actually causing my steering wheel to pop non-stop - took it out after 1 day.

Just a work of caution for you to look into.

When you guys get your Dorman shafts, can you see if they slide in/out fairly smoothly.

Mine was so tight that literally had to pound it in, and out - I removed mine after a day because it was forcing the entire steering wheel to pop non-stop.

By the sounds of it, I got the one in 1000 that was bad...but uh...thats just my luck....curious to heard from you others.  :wave:

Well..............I followed everyone's advice and bought the Dorman ISS from Rock Auto and even used the code to get the additional 5% off....thanks for the great info :thumbsup: I have had it for a couple of weeks and have certainly been meaning to get it installed to see if it actually fixes the problem but haven't gotten around to it yet.......with all the traveling I do I would rather play golf on the weekends but I am going to get around to putting it in......I swear (just in case the wife's listening ::)

Here's the rub............today I took my 04 1500 Z66 in for an Instrument Cluster replacement under the 7/70 extended warranty. My truck has a little over 52K miles but out of warranty for a little more than 2 years now. In any case when I was checking in this morning he asked if the truck had been in before and I said nope....never been in for anything other than just 1 recall and oil changes.......I haven;t even done brakes on this truck yet. In any case I mentioned that I should have had the ISS replaced under warranty but never got around to it...he didn't say anything.

When I was leaving and asking about what time the work would be done he gave me a time and said we'll have the ISS replaced as well.....NO CHARGE!!! When I went back this afternoon to pick it up they not only changed the ISS but also another "U joint" in the lower steering shaft as well as the tech noticed it was bad as well.........and they got it covered by the factory....even 2 years and 16K miles past the coverage period....my new favorite Chevy Dealer!!!! The ride home was amazing......the front end of this truck hasn;t felt this good for years.....why did I wait so long???? :E:

All in all pretty cool....only trouble is I now have a Dorman ISS that is surplus.......so if anyone is in need of one of these let me know and I'll make you a great deal, otherwise it will be one more of those things I will "Use someday" collecting dust in my garage.

Thanks to everyone on this thread for the help ( on the Cluster and the ISS issues), you certainly saved me a bunch of dough and heartache in trying to get it fixed.

All in all pretty cool....only trouble is I now have a Dorman ISS that is surplus.......so if anyone is in need of one of these let me know and I'll make you a great deal, otherwise it will be one more of those things I will "Use someday" collecting dust in my garage.

Thanks to everyone on this thread for the help ( on the Cluster and the ISS issues), you certainly saved me a bunch of dough and heartache in trying to get it fixed.

Cheers from southern CA

Thanks to everybody on this forum.

You have helped me get my baby back!!!

I have lived with my AV driving horribly for the last 2 years because I could not afford to have the front end looked at.  I found this forum and read about the ISS.   I immediately ordered the shaft from Rockauto.com and installed it (30 minute job) as soon as it came in.  My truck drives like new again!

I wish I had found this 2 years ago!!

Thanks again

If I've done all of these steps and still have a rattle in the steering shaft is my steering box going bad? Under the hood I grabbed the steering shaft with both hands-one at the top on the ISS and one below on the shaft from the steering box. I have no movement when I push down with the bottom hand and try to move the shaft with my upper hand. But when I flip the process and push hard on the top of the shaft and try to move the bottom I can see and feel some slight movement coming from the shaft leaving the steering box. Is there a bushing that I need to replace to correct that movement? Is there an existing thread that talks about this that I missed? I replaced my ISS with a Borgeson ISS two or three years ago but the rattle is back now worse than ever.

I replaced the OEM ISS with the Dorman shaft (from Summit Racing) and had a constant rattle, I removed the Dorman shaft and returned it to Summit and re-installed the OEM shaft.  I returned the Dorman shaft to Summit, they reshipped me a new shaft (received yesterday) but haven't had a chance to install it yet.  I hope this one is better.   :E:

I ordered the Dorman shaft from Summit about 6 months ago, and it was extremily tight, and caused a constant rattle/popping sound.

Most people report that they get good Dorman shafts...I suspect 1 in 20 of the dorman shafts are bad...they are made in China, but they appear to be a little more heavy duty. Its probably a manufacturing issue.

Im planning on trying a second one after summer...I can feel slop in my factory shaft with 79K miles.

Hi!

Ordered mine from rockauto on 1 september, got an e-mail the day after saying it was shipped and I got it today on the 7th.  :thumbsup:

And btw, I live in Sweden.

I've got a 2005 Avalanche that sure made a lot of noise from around the steering column when driving on bumpy roads at low speed.
It's all gone now  :D

The only real problem I encountered was that while listening to toby keith on my MP3-player connected to the AV (thanks for the tip about aux input connected to cables running from XM)
was that when I disconnected the cable to the gas pedal a warning came on (reduced engine power) I then turned the ignition off and continued my install of the ISS.

When I was done and about to take it for a test run the Engine Light came on and would not disappear.  :beating:

I ran inside and went online and searched but couldn't find anything about it.
I went outside again after about 5 minutes to disconnect and connect the cable to the gas-pedal again but when I came out the light would not come on.  :thumbsup:

So I went for my testrun and now the ride is as smooooth as it should be, even on bumpy roads  :D

Thanks for all the great information on this forum!

Keep in mind, it eliminates that feeling of the "popping" in the front end you can feel to the steering wheel. Mine did it when turning at slow speeds on uneven ground.. If you don't have that problem, or something mentioned that has been cured as posted by other members, why change it? you might already have a nice tight feeling truck like everyone else wants again! haha Sorry to hear you had a bad one already though....I had a popping noise that started the next day after install to about 4 days after install and it went away and works great with no noise and great feeling. I'm guessing it had to work lube into everywhere....

Good luck. Cheers!  :thumbsup:

Post by: 04JeffH on 10/17/10 09:07 AM
Replaced mine 10/16, after much discussion with my wife and reading the forum. She didn't think I could do it. I'm pretty good with general DIY stuff, but only recently have started working on my cars again, tired of paying for simple part swaps. Its the diagnosis that I'm not good at. This site helped.
 
Anyway, I didn't set any records but it wasn't hard. 90minutes mostly due to uncertainty and taking some time to think through it rather than giving up. I have power pedals, and decided to remove the boot and pull the shaft into the engine compartment rather than trying to pull it inside(not much room). That was easier for me, the boots is 3 10mm nuts and there is much more room to work under the hood. The hardest part of the hold thing, was wiggling the old shaft loose, I used a long screwdriver and mallet from inside and pulled and wiggled under the hood. Same issue with the new one, I had my wife push from the engine side and I guided on the floor, then wiggled and pushed the engine side in. Its a tight fit but with some grease and maniupulation not hard.
Anyone can do this if they can use tools, dealer wanted $130labor so that's what I saved. I spent $200 on the borgeson shaft bcause, I read several bad posts about the dorman, but seems there are mixed results on both.  The AV drives so much better, I've only had it 2mths and was feeling a lot of regret until this fix. Worth it!! Thanks to all.

gotta add to this great thread.

I bought the replacement ISS from my local dealer last winter, but just got around to installing it this past week-end.

It truly is like driving a new truck.  No more rattling, clunking, or vibration in the steering wheel.  It made a HUGE difference.

I bought part # 19153614 and it took me about 25 minutes to replace it in my 2002 Avalanche Z71.  15mm socket and ratchet to loosen the lower bolt in the engine bay and the same to loosen the upper bolt under the steering wheel.  After loosening both bolts with the ratchet, I removed them by hand.  Once both bolts were removed, I pulled the top part of the ISS down away from the top mount, then went into the engine bay and pulled the lower part of the ISS up and out of the lower mount.  Then, went back under the steering wheel to pull the ISS shaft out, into the cabin.  The new one was put in place by pushing it through the rubber boot in firewall and attaching the top bolt finger tight.  Then attach the lower bolt finger tight, then use ratchet to tighten.  Finally back under the steering wheel to tighten the bolt with the ratchet.  Done.


simple to complete and well worht it!

Post by: MileHiAV on 11/25/10 11:49 PM
This really is a no-brainer job.  My dealer quoted me $200...did it myself in 30 minutes minus 15 for cervezas.  My vote goes for removing the 3 10mm nuts on the boot on the firewall and pulling the shaft out through the engine compartment.  I threadlocked the nuts just to be on the safe side (not sure if it was required) The knocking is gone and steering is tight. Just an observation, you mention removing the spacer...I left that in since the stock one had it still in.  I figured it was in there to keep the tube from collapsing when you put the balls to it. I know it said in your instructions to remove it, but I figured, what  could it hurt leaving it?  Thanks for the great write up, this site is the best!  :thumbsup:

 :thumbsup:  Well, I finally got the new Dorman shaft and installed it yesterday. I was feeling a very slight clunk in my steering when going over roads with little cracks and bumps, so I figured it  was the ISS...and with the new shaft in, and no faint clunking, I now am sure thats what it was. The give-away was the faint clunking when at a stop and pressing the brake on and off.

I did have to "work" the dorman shaft for about 10-minutes to loosen it up, as it had a pretty bad sticky spot in it about 1-1/2" from fully compressed..and I lubed it with white lithium grease also.

I dont think my factory shaft was as bad as some people had, because the only difference I notice is the faint clunk being gone, and maybe just a slightly more precise steering, but not a major difference.

30 minutes total time, removed boot, did not loosen or remove power pedals at all. Shaft easily removes from engine side once 3 nuts are removed from boot and boot is pulled down. half the 30 minutes was me cleaning and re-lubing the inside of the boot to prevent the dreaded cold morning squeel.

i'm on my 3rd one, 1st ones had a "loose"feel(steering wheel had a lot of free play)after a few months. new one when extended all way had a blue coating like drive shaft splines do. the other two did NOT. i think dorman is still working out the bugs. :thumbsup:
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 01/27/11 09:31 AM
Mine has the Blue Coating on it, but like I said it had a VERY stiff spot on it when extending/retracting. Its now loosey-Goosey feeling, and I think Im gunna take it out and put the Original one back in. Its non-stop low-level clunking/popping now, far more than the small amount the OEM shaft was doing. Its very noticable over "smooth" pavement, as the small bumps dont cause tire noise, but the shaft has to expand compress a half inch or so...and I can feel it when stopped and press/release the brake pedal.

I guess Im out $45,,,crap.  >:( 

I know a lot of people really like the Dorman, but this is my second one with problems, and well, I just dont have patience for quality issues. It doesnt seem rational to replace a slightly defective part with a more defective part...HAHA!

Anyone else out there with similar problems?

Installing the updated shaft would use the same processes for shaft removal and reinstallation, the lubrication steps are skipped.

Doug,
        I just bought my first avalanche . It is a 2005 with 60,000 miles and i have a slight noise when i turn the wheel right or left, it makes a few  popping sounds when the wheel so d you know what this is and what you did would that fix my problem and why did you do this lube kit install ( remember i am new to this and don't now anything about avalanches) also where did you get the painted door handles
thanks for you help

Posted here but it was deleted!     ???

I have a `06 AV and I was having the rumbling noise from the steering at low speeds.  Thanks to CAFCNA I found the above thread and proceeded to replace the ISS according to the instructions found there and here.  One post in the above thread indicated that he was unable to remove the accelerator assembly.  Let me explain that it does take more than the two nuts to remove it.  The accelerator assembly is two parts:  1) the accelerator and the firewall bracket.  First remove the upper and lower bolts in the accelerator unit that attaches to the firewall bracket; then you can remove the three nuts that connect the firewall bracket to the firewall and move all to the side.  You will need a socket extension of about 4" to get to the middle nut.

Next, move the steering wheel so the upper bolt head is pointing down so you can get a socket on the 13mm bolt head (15mm nut...in my `06 case).  The engine bay bolt and nut are both 15mm.  I used the torque wrench to loosen the nut...leave loose and then get to the engine bay bolt and loosen and remove.  I did remove the firewall rubber boot that covers the ISS..only three nuts.  Went back inside to remove the nut and bolt then pulled out from the engine bay.

I used the gmpartsdirect.com ISS to replace mine.  Connected the ISS in the engine bay with the ISS extended into the steering wheel connection area.  Went inside and connected and installed bolt loose...make sure the boot is in place.  Firmed up the bolt/nut in the engine bay with the torque wrench set at 37 ft-lbs...may need to move steering wheel to get the bolt straight up and use a long extension(s) on the wrench.  Went inside and tightened also to 35 ft-lbs....Tested steering and no more rumbling!!!

If you still have your old OEM ISS shaft I would recommend doing the "grease Zerk mod" and re installing it. Once you fill it with a heavy duty grease it will not rattle, and in the rare case it does start in the future, just give it another pump or two. I did this mod last year and the results are very impressive.

Hi Guys,

Im replacing my ISS ony my 04 Ava as soon as it gets delivered. Ordered the Dorman version from Amazon.com for $40.79 and free shipping.

I was wondering, I read on another forum that you need to replace  green steering colum bearing as well, dorman part number 905-512. Is this true or should I be fine just swapping shafts???

Thanks.

Related ISS question with regard to steering. On my 03 Avalanche I am getting the "pop/clunk" sound at low speed so no doubt it is related to the ISS. However on reading several of the above posts can an ISS also contribute loose/ slop steering?


I have replaced the tie-rod ends and am still having a little bit of play in the wheel. The speed shop says that the truck is aligned perfectly. They checked the wheel bearing and said that the seemed fine. For the most part when I get on a level road and let go of the wheel it will drive straight. I can then move the wheel a inch or so and there is a little free play.

The ISS is on my list for the next week or so to replace but I wanted to see if this could be a contributing factor.

Hi all this is got to be the stupidest design gm has come up with...I friked around for a few hours getting this damm thing out just to see once I took the shaft apart that it has a hole in the end behind that upside down little insert. How dumb I was considering putting a grease nipple in the shaft prt but when I found out that there was a hole in the end I gave up I repacked it with some good silicone grease and reassembled it should be good for a few hundred ks. Next time I might just drill and insert a grease fitting so as no more taking it apart LOL :beating:

So I went to install the iss on my 04 Ava today and realized that the bolt in the dash is smaller than a 15mm. I tried other size sockets but can't find one that fits, a 12mm almost fits but not the right size. Anyone know what size it is????

Sorry for the stupid question I'm just tired of running back and forth to the toolbox. Lol. I tried standard sockets as well.

no ,ime wa 15mm you didnt round off the head did u? If so then ur going to have use something that can grip it to undo it. Or if the bolt head is rounded grabe it with some vise grips to undo it and once u get it out get a new 1 good luck

Post by: JonnyBlaze on 03/23/11 03:51 PM
So I swapped out my ISS today. Indeed it was a 15mm. Lol. Anyway, the old one was caked in grease and the shaft slid in and out very easily.

The new Dorman ISS doesnt slide out and retract very easily at all. Takes a good amount of pressure pull it out and collapse it. Is that normal?

And how can I tell if its original or not and how can I tell if it was even bad? I havent gotten to test drive the Ava since I replaced the ISS so I dont know if the clunking went away or not. I'll know tomorrow.

Heres a pic of the old shaft.

No doesn't look like anything is wrong with it and yes you need to put it in a vise to pull it apart. The only thing keeping it together is the grease inside that's creating a suction. Once I pulled mine apart I put some grease on it and inside the tube and @ the end where the bolt goes in behind the u clip or sleeve or whatever its called. Im going to drill the end and install a grease fitting too much work to be taking it out all the time just to fill it with grease.

Is the end of the shaft all beat up where it slides up against the top. Mine was very abused when I replaced it. My Dorman has been in for 3 years now and it is just getting about time to replace. I am going to replace the ball joints first and see if that is my issue.

I need to pull the one I just installed apart???

Ok, I called Dorman just now and talked to a guy from the tech line and he told me that they are supposed to be hard to extend and collapse and that it should take a fair amount of press to do so. And he said thats what the problem is with the old ones, that they were to sloppy and loose.

Sounds like you need and idler arm and pitman arm.


Well..... Got it all done. This Avalanche had some serious steering problems since I bought it. It now however after all the work drives like a Champ. JonnyBlaze you were right (pitman arm) in addition to the ISS.

Now onto the next project.... Shocks!  :drive:

Can your alignment cause the steering to feel lose on straight roads but normal on corners? Also is there a way to make the power steering less power and more steering? In otherwords I would like more feeling in the steering like when it was new.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 04/26/11 06:51 AM
In My experience yes, especially so. The reason is because around corners there is a lot of force being applied to the tie rods, pitman, and other linkages, going straight will allow all the loose stuff to drift back-forth.

If you feel a loose situation going around a corner....something is seriously ready to break...not good. I hat a pitman break once...not fun.

QUESTION-Is GM p/n 19153614 the latest supercede for the ISS (there have been a bunch of p/ns for it over the years)? I replaced my factory shaft with the $$$Borgeson a couple of years ago, and it's now worse than the original OEM part. Back to the cheaper OEM shaft.

Im done with the Dormans. I know a lot of people have used them, but Ive managed to get two Duds in a row, and read a few other posts where the Dormans where extremely stiff to compress/extend (which is the ONLY movement an ISS is supposed to have)
Im Back to my Original OEM shaft which I saved. Its got less popping/play than the *new* Dorman.

There is another brand of ISS out there that is supposed to be good, but its in the $200 range. Someone mentioned it a few pages back.

I have replaced mine once with a Dorman - 06/25/09. So it has lasted for 2 years which is not great. Its only starting to have that loose feeling so very little. I will try another Dorman and see how it goes. May try the Silicone trick on the old one first.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 07/01/11 05:30 AM
You got better luck than me. My first Dorman made a loud popping sound from the day I installed it. It was just too stiff and was putting pressure on the steering wheel and steering gear house.

The second one was fine for about 1 month then started popping. Now I feel the slight clunk thru the pedals when going over small bumps, etc.

Its frustrating for sure. Why the Original ISS's fail so much is also stupid, but my original really isnt that bad, its better than my second Dorman.

The entire purpose of an ISS is to allow in-out movement between the steering column and the Chassis suspension/steering gearbox. That gear box moves up and down with the front suspension...so when you get an ISS that wont move in/out easily, it defeats the purpose, and places a large amount of stress and force to the steering column and Steering wheel assembly.

The most common cause of ISS failure is lateral movement of the shaft, where is wobbles in the shaft, which causes the loose steering feeling and also causes popping/clunking especially when at stop lights pressing and depressing the brake pedal.

I took my new dorman out a month-1/2 ago and it was still binding up going in and out, so I lubed it up hoping it would make it better and it hasnt. So when I get unlazy I plan on sticking the old OEM back in.

Hey there Shanes02 - I think I remember talking to you about that a while back...your still going well I assume?

I wonder if they changed factories or something from a few years ago? The area where both of mine bind up is where the blue plastic coating on the inner shaft is coated. I worked the second one in/out for over 1-hour before installing, it was still very stiff to move. I was hoping installing it for a few months would wear it in, but it actually gotten worse.
 Ah well, cant win em  all.

My Dorman has been the best thing that Ive ever done to my truck.

Now I got to figure out where the clunking is coming from when my truck upshifts. Doesnt do it when I am on itm just when Im feathering it like I normally do. Pisses me off. I already replaced the ujoints.

Post by: Shanes 02 Avalanche on 07/01/11 10:00 AM
Mine does that also from first to second when you are just almost coasting. I thought it was my Hypertech to I removed it but that did not help. So I just installed it again. It does drive you nuts. I took my tranny in for its regular service and had them check it to see if it was the problem. They checked everything from the Tranny to the rearend and nothing is lose or wrong.
So basically they could not find anything either. They thing it might just be the way the tranny shifts with a more positive clutch instead of the older slip style.

Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 07/05/11 08:46 AM
So this clunk your having is only when downshifting?

Reason I ask, is my Dorman ISS is the source of clunking I can feel in the pedals and steering wheel. The previous Dorman was Clunking and popping loud, this one is mild, and I only feel it at slow speeds, or when stopped at a light and press the brakes.

Its possible its the ISS - did you have the clunking before you switched the ISS ?

It does it during upshifts, 2-3 upshift. I went to a local tranny shop and had the owner drive it and he said its 100% normal. So whatever. I guess I'll live with it.

Its not coming from the front or ISS. I know what that sounds like cause I dealt with it before. Its coming from the rear.

Wowo i swear i have been trying to deal with the same clunk for the longest time.  The sound is obviously either tranny or rearend, and i have done everything short of rebuilding in an attempt to troubleshoot it.  I'm not willing to pay lots of money in hope to fix this noise, especially considering i have not noticed any performance negatives.  But its not in my blood to just ignore a problem.  ARGH the awful question of money now for potential fix or potentially more money later because multiple things have broken due to disrepair.

How long has your truck made this sound? What mileage did it start? Do you have 4x4 ?

Its possible it has something to do with the driveshaft going in-out of the tranny just barely..?

Can you force it to make the sound by putting it in and out of gear while not moving or is this strictly when the truck is at speed?

Ive only noticed it for a couple of weeks now. HAs 113k miles. I lubed the hell out of the slip yoke. It only does it at speeds. Around 15 mph and only if Im feathering the throttle not when I get on it at all.

The tranny shop said its mostly likely stuff just stretched out from age and theres nothing that can be done.

Hmmm...If its happening only when your feathering the throttle then it should also do it when your not moving at a stop-light.

If it does, you could troubleshoot the sound with the help of another person by putting on the Park Brake and using wheel stops, and crawl under there while someone else put it between neutral and drive.

I troubleshoot a similar sound on my Gs300 a few years ago and found the drive-shaft intermediate bearing bolt was loose. I dont know if these Avalanches have an intermediate bearing, I havent looked. but may be worth a try.

I was told from my tranny guy in Idaho a few years back that the tranny has a posi-lock system. And when you are going slow in first the tranny basically slams into second. It has something to do with the clutches in the transmission. It is not hurting anything and is normal on all 4L60 Transmissions. It is like the oil consumptions on all LS series engines. Just another GM thing.

But his noise started at 113K miles, so it seems like a newer issue creeping up.

Im wondering if there is a sticky solenoid or gunk inside the valve-body in the tranny that is making it shift a little harder than normal causing the clunk?

Maybe do a full Tranny flush, all 12-15 Quarts of Tranny fluid rather than the normal 4-5 qt pan drain...?

I heard a clunk when I slowed down real quick the other day while the tranny was downshifting. And it did it while I was turning on my road too.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: arizona-dave on 07/14/11 02:02 AM
Generally the ISS shaft will cause a low-key subtle constant "popping/light clunking" feeling in the brake and accel pedals and the steering wheel. Not a large or loud clunk. Also, generally a bad ISS is felt on smoother surfaces where the slightest uneveness or pebble on the road causes the ISS to pop or clunk...on rougher surfaces the rest of the vibrations overpower the ISS.

A really really bad ISS could clunk loud, but at that point your steering would feel completely messed up.

Hope this helps a little bit, I read somewhere on a different thread of a clunking sound coming from the Rear-End or Tranny upon Upshift and the members were told it was "normal" from both GM and non GM tranny techs, if your clunk was pretty loud it could have been a semi-loose suspension or tranny part settling or could indicate a drive-line or tranny issue.

I am curious to see if this is my steering play problem. Mine is 08 but I can see GM using the same shaft after all not everyone keeps their vehicles that long. So the U joint on the shaft could also cause the play.
Has anyone looked under the rubber boot as you get closer to the rack? I figure there are more U joints under there.

My OEM barely makes movement, and its U-Joint is perfect, I only feel the slight clunking while at a stop light letting on/off the brake pedal, other than that my Original ISS is good. Ive driven trucks and cars with bad ISS shafts, so I know when they really go bad how they feel.

Your problem sounds like either idler arm, pitman arm, or tied rods. Our a combination of the three. A bad ISS wont cause it to be all over the road.

Any chance it could be sway bar. I had to tight up the end links this weekend. The alignment to the sway bar slot is not exactly straight. Could give a brief explanation of what each does I suppose I could just google them.
The dealership also changed a control arm, but I don't think they actually know what to do.

So I have googled the 3 possibilities you listed. I have had multiple alignments with three different shops. Everyone of them suggest no problems. Even the dealership performed one today. I have and continue to have uneven tire wear. I used to wear the inside now I think it outside. Feathering in each case. The time before last rotate I had them flip the tire on the rim to get more mileage out of them. No noise for quite a few thousand miles. This rotate the noise is back and that was right after the rotate and hitting the highway. I love this truck but with this issue and the oil loss I might have to take a hit and trade it in.

Are your hub bearing assemblies OK?
You would think the dealer would get it right, i would take it back to them and explain, tell them to align it right... It shouldn't do that.

Some of these threads can get pretty long. Some have been running for 10 years. Whenever a member sees or feels a post should have it's own thread or is taking the subject off track the moderators will be glad to help by moving the posts and in some/most cases start the new thread. To make this easy and in my case possible send me a PM and include the number of the post in question. This will definately help target and fix the problem. This site really does belong to all of us, we all had a hand in making it and we all can have a hand in keeping it a fun and informative site for all Avalanche enthusiasts. Thanks

As for the lube Kit, I didnt use it, but I did re-lubricated my OEM shaft before putting it back in, after having 2 bad Dormans. It has no slop in it, and no clunking since. I had a friend turn the wheel side to side by less than 1 inch and the lower end of the shaft moved even with the smallest steering wheel movement, so thats good. But mine never had slop, it just had a subtle clunk sound at stop lights on/off brake pedal and over small bumps on smooth roads. My main problem is the noise the shaft makes against the rubber boot in the morning. I must be lucky to have a good OEM shaft, my truck has just over 80,000m now.

If it is clunking it is loose that is why it is clunking. As far as Dorman they have a known issue since they started having the parts made in a different country AKA China.


BTW this kit is not made any longer, so the best bet is to get the redesign shaft.

PS I did not want to often anyone with the made in china comment, but it is what it is.

Post by: arizona-dave on 10/28/11 03:53 AM
About the clunking: There are 4 types of clunks that can come from the ISS, mine was not due to a loose ISS, both ends were very tight. Ive replaced ISS's in several makes and models and one of the most typical symptoms of a bad/worn ISS is clunking felt in the pedals &/or steering wheel (sometimes able to hear a faint popping sound with the clunk feeling) while at a stop light or driving slowly and letting on/off the brake pedal, as well as feeling that same clunk when driving on smooth pavement.

Clunk Type 1) Most common: Due to inner shaft having play to the outer shaft, in essence the inner shaft is able to wobble side-side (lateral play movement). It required very little play to create this clunking. The shafts are only supposed to move in-out, not side-side.

Clunk Type 2) U-Joint on ISS bad. Usually the shafts will develop lateral play before the U-joint in the shaft ever goes bad. The U-Joints are made of sealed hardened roller bearings.

Clunk Type 3) Loose ISS bolts either end.

Clunk Type 4) Binding inner to outer shaft, not allowing smooth in-out movement of the shafts.

In My case with the OEM shaft, the clunk/popping was VERY minor, and I only tried the Dorman cuz it was inexpensive and very easy to change.

But the Dormans I got did not allow the inner-out shafts to move in-out freely, they were extremely tight, and took all my weight to push in-out, that was definitely type #4 clunking - binding.

Anyway, I re-lubed the OEM shaft I think 6 or 7 months ago, and no minor clunking, it will come back, but I will just re-lube it since the lateral play and clunking was so minimal anyway.

If it is clunking it is loose that is why it is clunking. As far as Dorman they have a known issue since they started having the parts made in a different country AKA China.


BTW this kit is not made any longer, so the best bet is to get the redesign shaft.

Found a lube kit at my local dealer.  Parts managers said GM was phasing them out, but that he uses them all the time.  Asked me how I heard of them, since general public doesn't know they exist.

The one I picked up had same syringe and lube, with different plug, but worked fine.

Pretty easy install.  For future applications, I would think you can use the same syringe with bearing grease, or simply a grease gun with long tube, and accomplish the same results.

Well i had a big surprise...  I didn't need my Dorman ISS because when i replaced my (2nd ) wheel hub Asm the clunking that i thought was the ISS disappeared.  So my lube kit fix from a couple years ago is still effective!
Also i replaced the Hub ASM because the ABS light came on and the humming turned to grinding...

The lesson learned is don't wait on replacing those hub bearing Assemblies and it could fix multiple problems you are having.

So when you say Hub Asm, your talking about the entire 4WD Hub with wheel bearing, ABS Sensor housing, caliper connection and knuckles etc etc?

My factory original ISS is definitely got some play, but it doesnt clunk...the thing Im now noticing is wondering a little on highway especially at 70mph.

Im skipping the Dorman this time (had 2 very bad ones) and will go with another brand or a GM replacement (supposedly redesigned)

Prob wont do for a few weeks but I will post what my experience is once I get a good ISS back in.

Great info from the forum.  I noticed the clunking when I test drove my 2002 last month at a Jeep Dealer.  I kept firm on my offer to the Jeep Dealer stating that it sounded like a ball joint or bearings going and I had to figure the repair into the price.

I took it to my favorite Chevy dealer for repairs (not sales) and had them replace the part.  They reduced the price on the part to what you guys are paying via mail order but charged me two hours of labor.  I happily paid that since I would have wasted a precious sunny day here in the NW trying to do it myself.

The Av drives like new and now I am really happy with my vintage 02 Av with all bells and whistles functioning (except for the Analog Onstar).

2 Hours Labor? - In other words you really didnt get the part for what we pay on forum  :o

Its seriously 2 bolts and 20 to 30 minutes without needing to move anything difficult out of the way. (driving time to/from dealer, waiting for repair, etc ?)

In any event, glad you found this thread and at least were able to know exactly what was needing repaired and didnt get hosed for all sorts of other stuff.

On a different note, I have this steering sound only while turning left...ARG!!! - Its not the ISS as its been replced...now what! http://chevyavalanchefanclub.com/cafcna/index.php/topic,131102.0.html

My steering wheel has play in it (side to side) - a little scary. It vibrates / chatters when i hit bumps or railway tracks. Took it in to the GM dealer and they said the steering box is good and front end is solid, so they will replace the entire steering column assembly as it is under warranty....a couple grand. They said they wouldn't muck with my bushings etc in the column, so I'm happy. Let's see what happens . I like that they are not messing around and will solve my issues with OEM replacement parts. Their changing the back window under warranty too as the frame has cracked.

I can't remember which forum section I posted it in, without looking but, I had popping noise in my left turns when it was cold out or over decent size speed bumps. I also had quite a bit of play in my steering. Like I could move the steering wheel left and right by about almost an inch and a half both ways without the wheels hardly movin. I decided to tighten up the steering box. No more than a total of 1/2 turn, as recommended by the youtube vid and in forums related to steering adjustment. For almost a month my popping noise went away but now it is back every once in a while like it was when the noise first started happening. I started happening ever time I turned the steering wheel to the left only before I tightened the steering box. When I went to tighten the box I did notice the box was leaking out of the bottom spline and on the top somewhere. So I plan on changing that out this spring/summer when I do my other things I wanna do to Avy.

Post by: Shanes 02 Avalanche on 01/04/16 08:35 PM
I talked to my mechanic about tightening the steering box and he said it could cause excess wear on the parts that could cause leaks. So I opted not to tighten the box. My steering is a little light for such a heavy truck, I have replaced my entire steering rack and a-arms. My steering is still the same. But since I have driven it for 227000 miles I am very use to it. The wife does not like it, but she drives a 93 Honda Civic.
I am still debating about tightening the power steering maybe a 1/4 turn and see where that takes it.

Replace the steering box because there's a needle bearing on the pitman shaft that wear out, tightening the screw will only make it worst.
Title: Re: Intermediate Steering Shaft Removal/Lube Kit Installation
Post by: Avalanche0579 on 01/04/16 08:45 PM
I didn't tighten it all that much. Just a 1/2 a turn total until the movements of the steering wheel and the tires moved in sync. I do plan on replacing mine. This will get me though the winter to where I can have decent weather to do it. I just think it is kind of weird that after tightening the box just a tad, that my popping went away. After I tightened the box, the first couple of days I did all sorts of hard turns and bumps even bumps while turning and there was no popping.

Now do you see what tightening the nut does, it pulls the shaft up and cause more problems.

I think you are good to go till the weather gets better.

Indeed I do. Like i stated though, it was already slightly leaking before I tightened the box up. Looked like it had been leaking for a few months before I even though about tightening the box. Steering is firm again like it was new. Just a temp fix. I'll be doing quite a few things this spring summer so just another to add to the list. Now if I can just find nerf bar extender brackets I'll be happy. Gettin tired of only being able to get my toes on the darn nerf bars while steppin in to Avy. May have to take them off and take the brackets in to a machine shop and have new ones made that are a little longer. Every winter I slip off the darn things at least twice because of how close they are to the body.

Lookin at Rock and see the ACDelco one for $149.79   core$100.00  $249.79 total or looking at the Detroit one on amazon for $224. Just leery of manufactured stuff like this. At least the Detroit one has a lifetime warranty.

2013 Avalanche, LT, Z-71, 45K miles. 

I have a slight clunk that is felt in the steering wheel when first starting the vehicle and making a turn, and intermittently when driving.  Thoughts on this being the ISS? 

For clarity/emphasis:  happens almost every time when turning wheel after being parked.  Only happens occasionally when driving, but does occur.  Clunk is felt in the steering wheel (versus pedal, seat vibration, etc.), and feel like a millimeter of play that gets absorbed/stopped when turning.  Bumpy road does not cause it to present.  An update:  if I pull or push with force up, down, left or right, on the wheel, even when vehicle is stopped. I can recreate the click/clunk. Feels like it is right behind the steering wheel.

On my 2003, Avalanche, I had replaced the ISS, but that was a more consistent clunk, and was felt on bumpy roads.

TIA
