Cover Seal: Removal

NOTE: The 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 determine the most appropriate service procedure. This procedure will correct a brown/black (gear lube) leak from the RH side of the PTU. 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.

Remove the intermediate shaft seal and deflector. Refer to INTERMEDIATE SHAFT SEAL AND DEFLECTOR .

NOTE: There is a bearing inside the PTU directly behind the cover seal. The bearing is not serviced.
