Intermediate Shaft Seal and Deflector: Removal

WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. 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 determine the most appropriate service procedure. This procedure will correct a red oil leak (automatic transmission fluid) from the intermediate shaft seal on the RH side of the PTU. For additional information, refer to Analysis of Leakage in this section.

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.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING .
Remove the RH front wheel and tire. Refer to REMOVAL
Apply the brake to keep the halfshaft from rotating and remove the front wheel hub nut.
- Do not discard the nut at this time.

NOTE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.
