Well, I was under the cruiser today working on power steering and I noticed an oil leak line from the pinion running down to the bottom of the diff. How hard are these to fix? Could it be something else? ??? Thanks.
Be sure to properly stake the nut when done - very important! Also you might want to smear a bit of silicone caulk on the splines inside the companion flange before you push it on. This keeps oil from leaking through the splines.
I have the same thing on my BJ60 :'( I was able to unstake and tighten the staked nut about another 1/8 turn before I hit 140ft/lbs torque again. It wasn't making much noise but I've had my truck for nearly 15 years and I know how it's supposed to sound. How much time do I have before I need to do this? I was just in the axle last month to replace a leaking axle seal so I'm not too anxious to go back in Besides bearings, seals and gaskets are over $200 (2 pinoin bearings, 2 carrier bearings, pinion seal and diff gaskets).

You might be better off looking for a used low-mileage complete diff for that price. Unless your good at settin' up gears I guess... Anyway, I just traded both of my stock 3.70 diffs off--but they were in EXCELLENT condition for bein' outta a 1984. No play or leaks at all. I'm sure there are more in better condition... Just my opinion anyways...
