Out of the car and after a couple hours of pickin’ grunge out of the nooks & crannies, then some degreaser and power rinsing. Time to take it all apart.
Here’s what’s left of the 41-year-old 90-weight that came out of the rear diff (in glops). It’s almost solid enough to tar the roof!
Here’s the inside of the case after some time in the parts washer. Came out pretty clean, all things considered.
The diff looks GREAT after spending some time in the parts washer. All the bearings are still smooth, and the ring gear’s teeth are in awesome shape. New bearings and seals all around for this one though.
