    diff seal?

    Okay, car is relatively new, has enough run time to be broken in. It is not abused. Yet. I pulled the rear diff to shim and all the diff fluid was in bulkhead. I had no issues other than handling started to go away...So I put 1 shim and thicker fluid in after cleaning. The 3 screws seemed to be where fluid came out of. So I dabbed some blk rtv on top and bottom hoping it would help seal. Now I pulled front bulk head and same scenario. So I am going to give it the same treatment.

    My question is, what do you do to get a better seal on diffs?

    I think it is supposed to leak a little bit. As the oil heats up during the run it expands and has to go somewhere. Maybe try using associated green slime.

    did you inspect the edges? It could be slightly damaged in one spot and that would cause leaking
