    Questions -
    Bottles of gear oil about 1 quart. Is one bottle enough for differential changeout?

    You'll need 3 Quarts......it takes about 2.5 quarts to fill Rear Diff.

    I'm not sure on the exact gear oil weight for your particular application. It should be listed in a Haynes or Chilton manual. However, a safe place to start would probably be around 80W90, and limited slip additive if you have a limited slip differential, like the G80.

    EDIT: I'm also moving this over to the Maintainence forum since this is more a maint question.
