Installation Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, 2003 Chevrolet TrailBlazer, and 2002 Oldsmobile Bravada. 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.
  1. Install the bearing (print side out) using the J 45233  (2) and the J 8092  (1).
  2. Inspect the alignment between the differential bearing adjuster and the differential carrier assembly case. If the line between the differential bearing adjuster and the differential carrier assembly case is not aligned, re- align the 2 components as necessary.
