200,000 Mile Club

My 2003 1500 has 217k miles on it, Ive had it since new with little mods. I've decided to remedy that as money becomes available. Isn't that and wife's approval always the case.

My motor still runs great with no smoke and drives great. I did have to have the tranny rebuilt at 154K and just replaced the plugs for the second time, the knock sensors for the first time, as well as the AC clutch and the old valve cover gaskets in the last three months. I over towed a 6000 lb trailer for a while and carried more than the miniscule payload a time or three with lumber loads. Last year I replaced the pitman, and idler arms, upper and lower ball joints, sway bar links, tie rods and sway bar bushing. It's very tight now, and does (Can do...I surely don't exceed the speed limit ;). the sweeping 90 degree turn over then local freeway bridge on the way to the city at 90 MPH. Last summer I replaced the rotors with drilled and slotted ones, and bit the bullet for ceramic pads. It stops better than when I drove it off the lot in '03. I replaced the gauge cluster for less than a hundred bucks with all new gauges, and am on the third set of tires now.

I have put way less money into maintaining this Chevy than I have in my last 5 Fords, but I wish I had been more patient and waited to find the 2500 instead of this "1500 wannabe truck." With the price of decent 4x4 trucks starting at 50-60K these days, my $30K list of future overlander mods and a rotisserie restoration should result in my old AV. being better than any new 1/2 ton for half the price. Including the Raptor, that buy the way, has an equally low payload rating as my 1500.

Anyone ever stay with a 1500 and beef up the frame, steering box, brake booster, tranny cooler etc, for Dana 60's?

Thank you,
Don

Got almost 250,000 on my 2004 base model and traded it in for a 2008 2LT with only 54000 miles.
Thought I would need to settle for just a truck as I could not find any decent Avalanches.
love the Avalanche.
 
My 2005 Has 230,000 on it and I just changed oil yesterday. Daily driver since 2005. Been to most of the National parks in west. Roadtrips of thousands of miles summer and winter no problems. goes wherever I point it and still gives me good mileage. Thinking of a tuneup after a bit. Last tuneup was when she reached 100k. Been in desert, mountains, Plain. Very good vehicle Carries 4 large adults (european) in comfort. One knitting in back seat. Smooth ride and comfortable. Problems- none to speak of. Usual maintenance, keep clean and they last forever.
 
Ive got an 02 with 210xxx still going strong. Replaced water pump, brake booster, tires, and just regual services (oil, trans fluid, rear diff fluid)
 
I just got tags, title and insurance today. 2004 Z66.

It has 194858 on it.

Just had O2 sensor replaced. Knock sensor replaced, wiring harness replaced, brake pads replaces and both serpentine belts replaced.

Still needs headliner fixed, cracked dash and passengers side interior a-pillar fixed.

Lastly, put a cold air kit on it.

Next is exhaust in next couple of weeks.
 
Is there anyone out there who has over 200,000 on their Avalanche? Let us know what issues you have had if any? (Avalanche's are the best built truck out there)
Thanks, Durwin
2002 avy, 257,000. replaced water pump twice, fuel pump twice, alternator once, two weeks ago developed major electrical issues after fuel pump changed out, still not resolved
 
Mechanic says that the engine should go at least another 100,000 miles. only issue is the cataltic converter pipe needs replaced because someone replaced o2 senser and stripped the threads completely

exhaust shop can cut off old and weld on new O2 bung saving pipe but I would install new o2 sensors if they are older then 50k miles
 
I have 217,000 on a 2007 Avalanche LTZ. Just bought it and it has its problems.
Did the motor and transmission mounts.

03 with 255,301 fixed the ground wire off the back of the engine, keep up with all the fluids, have replaced the shocks, steering components, all the u joints, brakes, tires, battery, need to do a wheel bearing, she is having a random miss fire I think due to plugged up cats (have the new ones sitting in the bed) and am planning to have a custom exahust put up. other then that she runs great, motor is strong and no real issues to speak of other then the above.
 
It the big 200,000 miles this weekend, doing what she does best, towing.

I replaced the knock sensors & harness & after I put it all back together still had a knock sensor code 🙄

bring it to a shop they will need to clear the code or you can use a obd2 scanner and clear the code yourself or you can unhook the battery for about an hour then hook it back up and the computer will have reset. even after you replace the part that is causing the code, the code wont just go away you will have to manually clear it. I recently had to replace my oxygen sensors and cat part of exhaust (the y pipe) and still had code but fortunately i own my own scanner (was a mechanic for 20 years and now just mechanic as hobby not job anymore) and just had to clear code after installing new parts. my AV has 293,xxx miles on it just had that lifter tick but still running strong. engine still has at least 100,000 miles left on it
 
2007 Avalanche LTZ. Rear end bearings, Motor mounts, Transmission mount. tire sensors, crank shaft sensor. I hope that is it for a while.
