Use Of Synthetic Lubricants In Front Axle, Rear Ax

[troyboy]

I was wondering if this is a good idea and how much does each one hold?

If you look in the back of your owner's manual, you will see a section on recommended fluids and lubricants. It states what you should use, but does not say how much.

For 2002, this is on page 7-24, and for 2003 it's on page 6-17.

For both years, it recommends natural lubricant for the front, and synthetic for the rear. I have heard of problems with differential seals failing and resuilting leaks if you use the wrong type of lubricant in your differentials.

I believe the rear holds approx. 3qts., however the level should be approx. 40mm BELOW the fill hole.

I know that Gandolphxx had a problem with his front after swapping it to synthetic, so to echo SS stick with the regual gear lube in the front, and the synthetic (75W-90) in the rear.

anybody know how much the front diff holds?

Just a little less than 2 quarts if it's a half ton 1500.

Do you know if this was this because of the "black type vent connector hose" that is supposedly not compatible with synthetic oil or some other reason?

I read a service bulletin on this, stating that a black connector hose is not compatible but the white one is.

I ask because I was thinking about using the synthetic 75w-90 in mine as well (1500 '04)

Thanx
