Cover Seal: Removal

WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The Power Transfer Unit (PTU) may leak different color fluids, red oil leak for automatic transmission fluid and brown/black gear lube for PTU fluid. The PTU seals prevent these types of fluids from leaking. It is important to note which color fluid is leaking to conduct the most appropriate service procedure. This procedure will correct a brown/black (gear lube) leak from the RH side of the PTU. For additional information, refer to Analysis of Leakage .
NOTE: This procedure is to be performed through the RH wheel opening. It is not necessary to remove the exhaust components to complete this repair.
  1. Remove the intermediate shaft seal and deflector. For additional information, refer to Intermediate Shaft Seal and Deflector .
    2. NOTE: There is a bearing inside the PTU directly behind the cover seal. The bearing is not serviced.
  2. Remove the cover seal using the Slide Hammer, the extension from the Halfshaft Remover and a suitable seal puller inserted into the groove of the seal.
