Removal Procedure

Important: Do not rotate the center slip yokes to spline shafts, end yokes, companion flanges, etc. from their original position during reassembly. You must observe and accurately reference mark all driveline components relative to the propeller shaft and axles before disassembly. These components include the propeller shafts, drive axles, pinion flanges, output shafts, etc. All components must be reassembled in the exact relationship as when removed. You must follow specifications and torque values, as well as any measurements made prior to disassembly, in order to maintain the factory balance.

  1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Reference mark the propeller shaft to the to the transmission.
  3. Reference mark the propeller shaft to the rear axle pinion yoke or to the flange yoke.

  4. Remove the bolts and the yoke retainers from the rear axle pinion yoke or the bolts from the flange yoke.
  5. Notice: When removing the propeller shaft, do not attempt to remove the shaft by pounding on the yoke ears or using a tool between the yoke and the universal joint. If the propeller shaft is removed by using such means, the injection joints may fracture and lead to premature failure of the joint.

  6. Slide the propeller shaft forward in order to disconnect the propeller shaft from the rear axle pinion yoke or from the yoke flange.

  8. Slide the propeller shaft rearward in order to disconnect the propeller shaft from the transmission.
  9. Remove the propeller shaft from the vehicle.

Installation Procedure


    Object Number: 404287  Size: SH
  1. Install the propeller shaft slip yoke into the transmission.
  2. Align the reference marks made during removal.

  3. Install the propeller shaft to the rear axle pinion yoke or to the yoke flange.
  4. Align the reference marks made during removal.

    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: Discard the bolts to the yoke flange. Use new bolts.

  5. Install the yoke retainers and the bolts (pinion yoke type) or the bolts (yoke flange type).
  6. Tighten

        • Tighten the yoke retainer bolts to 20 N·m (15 lb ft).
        • The new yoke flange bolts to 102 N·m (75 lb ft).
  7. Lower the vehicle.
