Disassembly Procedure


    Object Number: 524806  Size: SH

    Important: Do not cut through the halfshaft inboard seal and damage sealing surface of the outer housing and the trilobal tripot bushing.

  1. Disconnect the small seal retaining clamp from the halfshaft bar using a side cutter. Discard the small seal retaining clamp.
  2. Remove the larger seal retaining clamp from the tripot joint with side cutter and dispose.
  3. Separate the halfshaft inboard seal from the trilobal tripot bushing at the large diameter.
  4. Slide the seal away from the joint along the halfshaft bar (4).
  5. Remove the housing from the tripot joint spider and the halfshaft bar (4).
  6. Spread the spacer ring (3) with J 8059 .
  7. Slide the spacer ring (3) and tripot joint spider (2) back on halfshaft bar (4).
  8. Using J 8059 , remove the spacer ring (1) from the groove and the halfshaft bar (4).

  9. Object Number: 233595  Size: SH
  10. Slide the tripot joint spider (1) assembly off the halfshaft bar (3). If necessary, use a brass hammer.
  11. Clean the following items with cleaning solvent:
  12. • The tripot balls
    • The needle rollers
    • The housing
  13. Remove all traces of old grease and any contaminates.
  14. Dry all of the parts.
  15. Remove the trilobal tripot bushing from the housing.

  16. Object Number: 245267  Size: SH
  17. Remove the spacer ring (2) and the seal (3) from the halfshaft bar (4).
  18. Inspect the following parts for damage or wear:
  19. • The halfshaft inboard seal (3)
    • The tripot joint spider assembly (1)
    • The housing
    • The trilobal tripot bushing
    • The tripot balls
    • The needle rollers

Assembly Procedure


    Object Number: 214026  Size: SH
  1. Install the small seal retaining clamp on the neck of the halfshaft inboard seal. Do not crimp.
  2. Slide the inboard seal onto the halfshaft bar.
  3. 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.

  4. Position the neck of the inboard seal in the seal groove on the halfshaft bar.
  5. Tighten
    Crimp the seal retaining clamp (1) using J 35910 to 136 N·m (100 lb ft).


    Object Number: 524806  Size: SH
  6. Install the spacer ring (3) on the halfshaft bar (4) into the second groove.
  7. Slide the tripot joint spider assembly (2) toward the spacer ring (3) as far as it will go on the halfshaft bar (4). If necessary, use a brass hammer.

  8. Object Number: 221915  Size: SH
  9. Install the spacer ring (2) in the groove of the halfshaft (1) using J 8059 .
  10. Place approximately half of the grease from the service kit in the inboard seal. Use the remainder of the grease to repack the housing.
  11. Install the trilobal tripot bushing to the housing. Ensure the trilobal tripot bushing is flush with the face of the housing.
  12. Position the larger new clamp on the inboard seal.
  13. Slide the housing over the tripot joint spider assembly on the halfshaft bar.

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

  17. Position the joint assembly at the proper vehicle dimension (dimension a=105mm (4 1/8 in.)).

  18. Object Number: 243212  Size: SH

    Important: Align the following items while latching:

       • The halfshaft inboard seal (3)
       • The housing (1)
       • The large clamp (2)

  19. Latch the seal retaining clamp (2) with J 35566 .
