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?
