The rear differential had started to weep a wile back and recently had gotten worse so I decided to clean it up. I have no idea when this was lat done, if ever, so I wasn’t sure what to expect. I cracked the bolts on the AMC 20, let the fluid drain and here’s what I had:
It was real full, I think about 3 quarts poured out of it. The gears looked good and there was no bits of metal or anything out of the ordinary. The service manual lists only needing about a quart so either it has slowly filled up from little adds here and there or somebody over filled it after a reseal. I wiped it down, cleaned up the cover and applied gasket material. In cleaning up the cover, I removed all the grease, dirt, surface rust and flaking paint before hitting it with some primer and paint.
It was pretty easy. I’m going to let it cure overnight before I add fluid. Next up will be the front.
