Assembly Procedure

Tools Required

    • J 35910 Seal Clamp Tool
    • J 35566 Earless Seal Clamp Tool
    • J 8059 Snap Ring Pliers

    Object Number: 214026  Size: SH
  1. Install the small boot retaining clamp (1) on the neck of the inboard boot. Do not crimp.
  2. Slide the boot onto the halfshaft bar.
  3. Position the neck of the boot in the boot groove on the bar.
  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. Crimp the boot retaining clamp (1) using J 35910
  6. Tighten
    Crimp to 136 N·m (100 lb ft).

  7. Check gap dimension, continue tightening until gap dimension is reached.

  8. Object Number: 221915  Size: SH
  9. Install the spacer ring (2) on the halfshaft bar (1) and beyond the second groove.
  10. Important: Ensure that the counterbored face of the spider assembly faces the end of the bar (1).

  11. Slide the spider assembly toward the spacer ring as far as it will go on the bar.
  12. Install the second retaining ring in the groove at the end of the bar (1) using J 8059 .

  13. Object Number: 221913  Size: SH
  14. Slide the spider assembly (2) towards the end of the bar (4).
  15. Reseat the first spacer ring (1) in the groove on the bar (4).
  16. Place approximately half of the grease from the service kit in the boot. Use the remainder of the grease to repack the housing.
  17. Install the trilobal tripot bushing to the housing. Ensure the trilobal tripot bushing is flush with the face of the housing.
  18. Position the larger new clamp on the boot.
  19. Slide the housing over the spider assembly on the bar.

  20. Object Number: 221916  Size: SH
  21. Slide the large diameter of the boot (2), with the larger clamp in place (3), over the outside of the trilobal tripot bushing and locate the lip of the boot in the groove.
  22. Important: The boot (2) must not be dimpled, stretched out or out of shape in any way. If the boot (2) is not shaped correctly, carefully insert a thin, flat, blunt tool (no sharp edges) between the large boot opening and the trilobal tripot bushing to equalize the pressure. Shape the boot properly by hand. Remove the thin, flat, blunt tool.

  23. Position the joint assembly at the proper vehicle dimension.

  24. Object Number: 243212  Size: SH
