Thanks to all that replied. The leak is not coming from the the large gasket on the PIG, but from the pinion drive shaft input. Do I really have to pull the axlesshafts to remedy this problem? I have a 9" rear break down. It shows right behind the the drive shaft input flange a seal and
oil slinger. Could this be the culprit for the leak? This seal appears to be similiar to the output seal on a TREMEC TKO TRANNY. I have not install the driveshaft yet. What I am getting at is with the drive shaft being absent does this put pressure on that seal rolling the chasis in and out of the garage?
