Differential Housing Cover: Installation

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: Make sure the machined surfaces on both the axle housing and the differential housing cover are clean and free of oil before installing the new silicone sealant. The inside of the axle housing must be covered when cleaning the machined surface to prevent contamination.
  1. Clean the gasket mating surface of the axle housing and the differential housing cover.
  2. Apply a new continuous bead of sealant to the differential housing cover.

  4. Install the differential housing cover and the differential housing cover bolts.
