I'm going to stretch the definition of A-body. I have a dodge A-108 van. It has the differential in the above title of the post that's used in lots of old mopar vehicles. I'm replacing the wheel bearings along with the seals and gaskets. The gaskets are thin metal and they replace paper gaskets. The metal gaskets have a ridge running around the diameter ( or a groove if you look on the opposite side). With the paper gaskets both sides were same but with the metal ones you have to decide which way to face them. I think they updated the gaskets to stop them leaking gear oil on the brakes and the inside sides of the tires. That's what mine were doing so I want to get it right. This is assuming it makes a difference.The order the parts go on in starting at the inside side of the vehicle is: flange on the rear axle housing - gasket - brake mechanism mounting plate - gasket - axle retainer plate. There are 4 identical gaskets - 2 to each side.I hope this isn't too confusing. Any advice would be welcome.
