Tools Required

    • J 35566 Drive Axle Seal Clamp Pliers
    • J 42572 Drive Shaft Seal Clamp Pliers

Disassembly Procedure

  1. Remove the small seal clamp from the wheel drive shaft bar using side cutters and discard the clamp.
  2. Important: Do not cut through the wheel drive shaft outboard seal and damage sealing surface of the outer housing and the tripod bushing.

  3. Remove the large seal clamp from the tripod joint with side cutters and discard the clamp.
  4. Separate the wheel drive shaft outboard seal from the tripod bushing.
  5. Slide the seal away from the joint along the wheel drive shaft.
  6. Remove the housing from the tripod joint spider and the wheel drive shaft.
  7. Important: The correct 60 degree offset relationship between the inner and outer tripod spiders must be maintained. Accurately reference mark the tripod spider position on the wheel drive shaft bar before disassembly.

    • The housing
    • The tripod bushing
    • The bearing

Assembly Procedure

  1. Using a press, install a new bearing.
  2. Important: Before installing the boots on the shaft, wrap the splined area of the shaft with vinyl tape to protect them from damage.

  3. Temporarily install the boots and clamps.
  4. On the right hand drive shaft, install the dynamic damper.
  5. Position the beveled side of tripod axial spline toward the outboard joint.
  6. Align the reference marks, then install tripod to the outboard joint shaft.
  7. Install a new snap ring.
  8. Pack the outboard joint and boot with approximately 135-155g (4.8-5.5 oz) of green/blue grease.
  9. Pack the inboard joint and boot with approximately 135-155g (4.8-5.5 oz) of dark yellow grease.
  10. Align the reference marks on inboard joint shaft and outboard joint shaft.
  11. Temporarily install the boot to the inboard joint.
  12. Install the boots into the grooves on the drive shaft.

  13. Object Number: 825338  Size: SH
  14. Measure the right hand drive shaft to ensure that the shaft is at standard length before installing the boot clamps.
  15. Specification
    Right hand standard drive shaft length for:

    • 2WD models (1) is 843.3-853.3 mm (33.201-33.595 in).
    •  AWD models (2) the standard length is 855.0-865.0 mm (33.661-34.055 in).
  16. Measure the left hand drive shaft to ensure that the shaft is at standard length before installing the boot clamps.
  17. Specification
    Left hand standard drive shaft length for:

    •  2WD models (3) is 577.3-587.3 mm (22.728-23.122 in).
    •  AWD models (4) the standard length is 566.9-576.9 mm (22.319-22.713 in).

    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.

  18. Using the J 42572 , crimp the small seal retaining clamp.

  19. Object Number: 709028  Size: SH
  20. Install a new barrel retaining ring to the wheel drive shaft bar.
  21. Important: The proper 60 degree offset relationship between the inner and outer tripod spiders must be maintained.

  22. Align the reference mark on the tripod spider and the wheel drive shaft bar.
  23. Important: Ensure that the beveled edge of the tripod spider faces the wheel drive shaft bar during reassembly.

  24. Install the tripod spider to the wheel drive shaft bar, while compressing the barrel retaining ring with a flat-bladed tool.
  25. Verify positive engagement of the tripod spider to the wheel drive shaft bar by grasping the tripod spider and attempting to pull free from the wheel drive shaft bar.

  26. Object Number: 746537  Size: SH

    Important: Ensure the tripod bushing is flush with the face of the housing.

  27. Place approximately half of the grease from the service kit in the wheel drive shaft outboard seal. Use the remainder of the grease to repack the housing.
  28. Install the tripod bushing (5) to the housing (1).
  29. Install the spring (2) to the tripod housing.
  30. Use grease from the housing in order to retain the spring.

  31. Install the guide (3) to the spring.
  32. Use grease from the housing in order to retain the guide.

  33. Position the larger new seal retaining clamp (4) on the wheel drive shaft outboard seal.
  34. Slide the housing over the tripod joint spider assembly on the wheel drive shaft bar.

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

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

  39. Object Number: 325997  Size: SH
  40. Align the following items while latching:
  41. • The wheel drive shaft outboard seal (1)
    • The tripod housing
    • The large seal retaining clamp (2)
  42. Using the J 35566 , latch the large seal retaining clamp. Ensure that the latching tangs are fully engaged in the large seal clamp band.
  43. Rotate the outer tripod housing four or five times in order to distribute the grease throughout the tripod spider bearings.
