I found a very very slow leak on my pinion bearing - I believe it's a bad seal - does anybody have instructions on replacing these?
I have no lift, just jacks, and tire ramps to do this with, so as much information as possible would be helpful.
Oh, and I have a 96' 4WD.

 

 

How do I know beforehand which seal is leaking (if I remember right there are 2 - an inner and outer, right?)

 

If its anything like my 93 olds bravada rear end, its a simple fix. What makes you think there is bearing failure? There is usually only one seal on any light duty rear end pinion. The hardest part of doing this was getting the pinion nut to break. You need a special tool called a pinion flange holding tool or you can improvise and use something like a very largemonkey wrench (3 foot) like I did and a nice breaker bar w/ large socket (can't remember size- 1"3/8 or mm equivalent maybe). Once you break the nut, you'll need a suitable puller to pull the flange off of the spline shaft. NO IMPACT WRENCHES... but plenty of pb blaster will help. Pull old seal out, put new one in and follow the instruction swartlkk has posted before doing anything I've said. If you have any ??'s,just ask.

 

Nope, just a lip seal on the outside. It seals on the pinion yoke. If you have a leak on the front of the differential where the driveshaft connects, the lip seal is at fault.

The title is a bit misleading...
