Thanks for help, I have contacted dr diff.

Ok then I need new set of the inner axle seals and can possiblle exchange the bearing while its open and axles out. Are these parts specific for each case type or universal for any 8 3/4 rear end?



the seals and the axle bearings are the same across the years for the 8 3/4 rear in passenger car applications , trucks and vans may be different.

The links you posted above are the correct bearins , the first link is the factory axle bearing , there are 2 seals that also are part of the bearing assembly. one is a dust seal in the end plate and the other is the axle seal that goes in the axle tube.

It's a bit of work to swap out the axle bearings but not hard for a novice to do , a press is needed to reinstall the bearings without damage.
