PTU Leaks From the RH Side
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Remove and replace leaking seals using the information found in the Intermediate Shaft Seal and Deflector or Cover Seal replacement procedure. The specified tools called out in this procedure will allow seal replacement without causing damage to the Power Transfer Unit (PTU) casing/drive gear.
If the leak is red automatic transmission fluid, this indicates the differential seals in the transaxle are also leaking and need to be replaced along with the intermediate shaft seal. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION - AISIN AW21 article to replace the differential seals before replacing the intermediate shaft seal. Refer to the Intermediate Shaft Seal and Deflector procedure to replace the intermediate seal.
If the leak is brown/black gear lube, then the PTU larger cover seal needs replacement. This is located on the PTU cover behind the deflector. Refer to Cover Seal procedure.
