Installation Procedure

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: The seals used in the differential carrier assembly have built in tabs that are used to retain the position of the differential side bearing adjusters. When installing the seal, it is not necessary to align the tabs to the slots on the differential side bearing adjuster. Two of the tabs on the seal will automatically align themselves with the slots on the differential side bearing adjuster when the seal is installed.
