       • The propeller shafts
       • The drive axles
       • The pinion flanges
       • The output shafts
    Reassemble all of the components in the exact relationship to each other before removal. Follow the specifications, the torque values, and any measurements that were obtained prior to disassembly.

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

  3. Object Number: 384985  Size: SH

    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.

    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.

  4. Install the front propeller shaft yoke clamp bolts to the front drive axle.
  5. Tighten
    Tighten the front propeller shaft yoke clamp bolts to 20 N·m (15 lb ft).

  6. Lower the vehicle.
