How do you service a differential on a car?

Some vehicles have a differential drain plug, if so then unscrew the drain plug first. If not, then move on to step 2.

1.Unscrew the differential drain plug.

2.Unbolt the differential cover. (set a bucket under the differnetail to catch the oil)

3. Get the gasket off of the differential and differential cover with a razor blade and/or whiz wheel.

4. Replace the gasket with gasket sealer and/or the new gasket.

5.Bolt the Differential cover back on.

6.Fill the differential up in the top drain until the fluid starts to overflow.
