Axle Shaft Seals
WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Axle shaft oil seals are susceptible to the same kinds of damage as axle drive pinion seals if incorrectly installed. The seal bore must be clean and the lip handled carefully to avoid cutting or tearing it. The axle shaft journal surface must be free of nicks, gouges and rough surface texture. For additional information, refer to REAR DRIVE AXLE/DIFFERENTIAL - FORD 8.8-INCH RING GEAR .
