Keeping the fluid clean is a big plus, using a top grade oil helps, make sure you use the slip additive when changing oil or get a oil that has it in it. Not running a bigger tire than say 285/75r16 helps. I have some that I have rebuilt and they are fine like years on them, others did not last so long (months). N drops will kill them in a hurry.

 

I have 265/75/16's on my truck now..... But do I have to take the whole rear end off the truck... or can the rear diff be rebuilt with the rear end on the truck?

 

The rear end can stay under the truck, just need to pull the axles, carrier, bench work then re-assy, say 4 hrs work. You will need at least one special tool for the side adjusters. Have you found the FSM in the diy area? Have you ever worked on a diff before? this is not for the timid.

It will look like this when tore down.

 

I have replaced rear axle seals quite a few times.... I am mechanically inclined also. But no I have never rebuilt A rear diff. What is FSM?

 

FSM= Factory Service Manual in the 96 book page 132 or sec 3-66

Found here https://dodgeforum.com/forum/2nd-gen...e-manuals.html

 

Ok Great!! Thanks for the info!!

 

Have fun and post back your findings.

 

I deff will!! I know this has nothing to do with the Rear Diff.... But any chance do you know what cause my 4x4 indicator light to stay on? The $wd is not engaged and when I do engage the 4wd it works fine. Just curios why the light stays on

 

Most likely the sending unit at the CAD on the front diff, two wire plug.
