Removal Procedure

    Important: 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 to each other as they were when removed. In addition, published specifications and torque values, as well as any measurements made prior to disassembly must be followed.

  1. Reference mark the propeller shaft to pinion flange connection.
  2. Reference mark the slip yoke to the transmission for proper reassembly.
  3. When servicing driveshafts with the pop on seal, do not remove the seal from the sleeve. Removal of the seal causes damage to the seal lip where it contacts the sleeve yoke. If removal of the seal is necessary, replace the seal with a new unit.

  4. Remove the bolts.
  5. Remove the retainers.

    6. Object Number: 404282 Size: SH

    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. Remove the yoke and cross assembly, wrapping the bearing cups with tape in order to prevent the loss of bearing rollers.
  7. Remove the propeller shaft.
  8. Remove the propeller shaft.
    9. 8.1. Slide the propeller shaft forward.

    Object Number: 404284 Size: SH
    8.2. Lower the propeller shaft.
    8.3. Do not allow the universal joint to incline greatly. The joint may fracture.
    8.4. Remove the propeller shaft from the transmission.

    Object Number: 404287 Size: SH
  9. Use the following procedure in order to remove the front propeller shaft:
    10. 9.1. Always support the propeller shaft.
    9.2. Do not allow the universal joint to bend deeply as the universal joint could fracture.
    9.3. Remove the propeller shaft with a rearward movement.
  10. Clean all parts with an approved solvent.
  11. Inspect the outer diameter of the transmission yoke for burrs. Burring damages the transmission seal.
  12. Inspect the slip yoke splines for wear.
  13. Inspect for twisted slip yoke splines or possibly the wrong universal joint.
  14. Inspect the universal joint bearings for wear. Replace as necessary.

Installation Procedure

    Object Number: 404287 Size: SH
  1. Install the propeller shaft into the transmission.
  2. Lubricate the slip joint spline with chassis grease.
  3. Align the reference marks on the pinion flange and the propeller shaft rear yoke.

    4. Object Number: 404282 Size: SH
  4. Install the yoke and cross assembly onto the fixed yoke.

    5. Object Number: 1247 Size: SH
  5. Install the retainers.

    6. 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.

  6. Install the bolts.

    7. Tighten
    Tighten the bolts to 20 N·m (15 lb ft).
