Drive Pinion Seal: Removal

WARNING: This page is about a different car, the 2003 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: This operation disturbs the differential pinion bearing preload. Carefully reset the preload during assembly.
    WARNING: The electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the rear jack storage area. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations.
