How to Replace a Differential Seal in a 1962 Chevrolet
The rear end on a 1962 Chevrolet has a differential in the middle of the axle. This differential has a cover plate that allows for access to the differential assembly itself, and that cover has a seal between it and the axle housing to ensure there are no leaks. If a leak does develop in the differential cover, then the differential cover needs to come off so the seal can be replaced with a new one. This should take under an hour to do.

Slide the jack underneath the axle and lift up the jack so the axle comes off the ground. Put jack stands under the axle to support the car, positioned high enough that you can crawl under the vehicle to access the differential. Lower the jack and slide it out from under the Chevrolet.
