Disassembly Procedure
This procedure is to be performed only after the wheel drive shaft has been removed from the vehicle. Refer to
Front Wheel Drive Shaft Replacement - Left Side
or
Front Wheel Drive Shaft Replacement - Right Side
.
- Wrap a shop towel around the wheel drive shaft bar.
- Place the wheel drive shaft horizontally in a bench vise.
- Remove the small seal clamp from the wheel drive shaft bar using side cutters and discard the clamp.
- Using the
J 35566
or equivalent, unlatch the large seal retaining clamp.
- Remove the large seal clamp from the tripot joint and the clamp.
- Separate the wheel drive shaft inboard seal from the trilobal tripot bushing.
- Slide the seal away from the joint along the wheel drive shaft bar.
- Remove the housing (1) from the tripot joint spider and the wheel drive shaft bar (2).
Important: DO NOT reuse the old retaining ring, discard and replace with new.
- Using the
J 8059
or equivalent, remove the retaining ring.
Important: Accurately reference mark the tripot spider position on the wheel drive shaft bar before disassembly.
- Reference mark the position of the tripot spider (1) on the wheel drive shaft bar (2).
- Using a brass drift and hammer, carefully tap around the tripot spider to remove the tripot spider (1) from the wheel drive shaft bar.
- Remove the joint seal from the wheel drive shaft bar.
- Inspect the following parts for damage and/or wear:
• | The wheel drive shaft inboard seal |
• | The tripot joint spider assembly |
• | The trilobal tripot bushing |
Assembly Procedure
- Place the new small seal clamp (2) onto the small end of the inner joint seal (1).
- Slide the inner joint seal and the small seal clamp into the boot groove on the wheel drive shaft bar.
- Position the small end of the inner joint seal into the inner joint seal groove (3) on the wheel drive shaft.
Important: The seal retaining clamp must not be over-tightened or under-tightened.
- Using the
J 42572
or equivalent, crimp the small seal retaining clamp.
Tighten
Tighten the small seal clamp until there is a gap of 1 mm (0.039 in).
Important: If reusing the old tripot spider, align the reference mark on the tripot spider to the wheel drive shaft bar.
Important: Ensure that the beveled edge of the tripot spider faces the wheel drive shaft bar during reassembly.
- Install the tripot spider to the wheel drive shaft bar.
- Using the
J 8059
or equivalent, install a NEW retaining ring to the wheel drive
shaft.
- Verify positive engagement of the tripot spider to the wheel drive shaft bar by grasping the tripot spider and attempting to pull it free from the wheel drive shaft bar.
- Apply part of the grease from the service kit in the tripod housing, wheel drive shaft inboard boot and the tripod bearings.
- Install the trilobal tripot bushing (1) to the housing (3).
- Position the larger new seal retaining clamp (2) on the wheel drive shaft inboard seal.
- Slide the housing over the tripot joint spider assembly on the wheel drive shaft.
- Slide the large diameter of the wheel drive shaft inboard boot (2), with the larger clamp (3) in
place, over the outside of the tripot housing (1) and locate the lip of the seal in the groove.
Important: The seal must not be dimpled, stretched or otherwise deformed.
- Inspect the seal for proper shape.
If the seal is not shaped correctly, equalize the pressure in the seal by lifting the seal edge slightly and shape the seal properly by hand.
- Position the joint assembly to the proper vehicle dimension.
- Measure the distance (a) between the seal edges.
Specification
104.7 mm (4.12 in)
Important: Burp the air from the inner joint seal.
- Align the following items while latching the retaining clamp:
• | The wheel drive shaft inboard seal (1) |
• | The large seal retaining clamp (2) |
- Using the
J 35566
(3) or equivalent, lock the large seal retaining clamp.
- Ensure that the tangs are locked and fully engaged in the large clamp band.
- Move the inner tripod housing in 4 or 5 different directions to distribute the grease throughout the tripot housing and spider bearings.
