Installation Procedure

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the splines of the transfer case output shaft for a sufficient coating of grease. If the output shaft does not have a sufficient coating of grease, lubricate the shaft with grease (GM P/N 12377985 or equivalent).
    IMPORTANT: Ensure that the propeller shaft assembly is fully engaged into the slip yoke. The retaining ring will produce a snapping noise when the shaft is properly engaged.
  2. Install the propeller shaft to the transfer case.
  3. Install the propeller shaft to the front axle pinion yoke.

    Align the reference marks made during removal.

  5. Install the yoke retainers and the bolts.
    NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    Tighten 

    Tighten the front propeller shaft yoke clamp bolts to 20 N.m (15 lb ft).

  6. Lower the vehicle.
