Removal Procedure

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove the transfer case assembly. Refer to Transfer Case Assembly Replacement .
    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.
    NOTE: Do not damage the sealing surfaces of the transfer cases or the shafts when prying the seals for removal. Damaging the sealing surface may cause leakage or require replacement of the damaged component.
  3. Insert a flat bladed screw driver between the input shaft seal and the transfer case.
