I replaced the differential fluid yesterday. I drained more than a gallon out of it, which is in line with the specs, so it did not leak much fluid. Drain plug and o-ring seemed to be in good shape. However, this morning I noticed another drip on the driveway and a drop hanging from the bottom. Will try to replace the gasket on the diffcover and see if that helps. Any suggestions?

 

a gallon huh? sounds like a lot

 

Overfilling will cause a leak. The rear diff needs just over 2 quarts.

 

and then. how to do it with the plug half way down!!
