Removal Procedure

Important: The driveline components in this vehicle are factory system-balanced. System balance provides a smoother running driveline operation. Observe the position of all the driveline components. Accurately mark the relationship of the components before removal. These components include the propeller shafts, the drive axles, the pinion flanges, and the output shafts. All components must be reassembled in the exact relationship to each other as they were before removal. Follow the specifications, the torque values, and any measurements made prior to disassembly in order to maintain the factory system balance.

  1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Accurately reference mark the propeller shaft to the front axle flange.

  3. Object Number: 188296  Size: SH
  4. Remove the bolts from the propeller shaft to the front axle.
  5. Remove the propeller shaft.

Installation Procedure

  1. Install the rear of the propeller shaft to the transfer case.

  2. Object Number: 188296  Size: SH
  3. Install the propeller shaft to the front axle. Line up the reference marks made previously.
  4. Notice: 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.

  5. Install the bolts to the front axle.
  6. Tighten
    Tighten the bolts to 45 N·m (33 lb ft).

  7. Lower the vehicle.
