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 .

1. Wrap a shop towel around the axle shaft.
2. Place the wheel drive shaft horizontally in a bench vise.

Important: DO NOT reuse the retaining clamps. Replace with new.

3. Using a side cutter or other suitable tool, remove the retaining clamps from the outer boot. Discard retaining.
4. Remove the boot from the CV joint housing.
5. Remove the grease from the CV joint inner race, cage, and balls.
6. Remove the outer CV joint from the axle shaft using the following steps:

6.1.	Hold the outer joint housing horizontally to the shaft.

6.2.	Position a wood block between the seal and the joint, on the joint face.

6.3.	Using a block of wood and hammer, remove the CV joint from the wheel drive shaft. If the CV joint does not move, use a brass drift and a hammer to remove the CV joint from the wheel drive shaft.




7. Remove and discard the axle shaft retaining ring from the axle shaft.



8. Remove the boot from the axle shaft.
9. Remove the wheel drive shaft from the vise.



10. Wrap a shop towel around the joint outer race splined shaft.
11. Place the outer race vertically in a bench vise.
12. Using a brass drift and hammer, gently tap on the wheel drive shaft joints inner cage, until it is tilted enough to remove the first ball.



13. Remove the exposed ball. It maybe necessary to use a small screwdriver to remove the ball.
14. Position the cage and inner race so they are level.



15. Repeat steps 14-16 in the removal sequence as shown until all of the balls are removed.



16. Position the cage and the inner race 90 degrees to the centerline of the outer race.
17. Align the cage windows with the lands of the outer race.
18. Lift to remove the cage and the inner race from the outer race.



19. Position the cage and inner race so that the larger radius corners of the cage windows are up.
20. Rotate the inner race 90 degrees to the centerline of the cage.
21. Align the lands of the inner race with the windows of the cage.
22. Insert an inner race land into a cage window.
23. Pivot the inner race down and remove it from the cage.

Important: All traces of old grease and any contaminates must be removed.

24. Clean the following parts thoroughly with clean solvent:

•	The inner race

•	The outer race

•

The cage

•

The balls

•	The axle shaft exposed end

25. Thoroughly air dry all of the parts.
26. If any of the inner parts are found to be defective, replace the wheel drive shaft.

1. Position the cage so the larger radius corners of the cage windows are up.
2. Position the inner race 90 degrees to the centerline of the cage.
3. Begin to insert the inner race up through the bottom of the cage.
4. Align a land of the inner race to a window of the cage.
5. Insert the inner race land into the cage window.
6. Rotate the remainder of the inner race into the cage.
7. Rotate the inner race within the cage so that the grooved surface of the inner race is facing up.

Important: Ensure that the inner race is fully assembled into the cage.

8. Align the inner race ball tracks with the cage windows.



9. Wrap a shop towel around the joint outer race splined shaft.
10. Place the outer race vertically in a bench vise.
11. Position the cage and inner race 90 degrees to the centerline of the outer race.
12. Align 2 cage windows at 0 and 180 degrees, within the outer race.

Rotate the inner race and cage assembly downward in the vertical plane.





Important: The inner race ring groove must be positioned down.

13. Position the cage and inner race so they are level.
14. Align the cage windows and inner race ball tracks with the outer race ball tracks.
15. Position a cage window and inner race ball track for ball installation.

15.1.

Press down on the cage following one of the outer race ball tracks. The opposing cage window and inner race ball track will be accessible for ball installation.

15.2.

After installing the first ball, use a brass drift and a hammer to tap gently on the cage, in order to drive the cage and inner race down completely.

Important: No gap should exist between the ball and the inner race ball track.

16. Insert a ball through the cage window onto the inner race ball track.

Tap the ball lightly with a plastic tipped hammer.

17. Position the cage and inner race so they are level.




Important: The ball installation sequence must be followed as shown.

18. Repeat steps 17-19 in the installation sequence as shown, until all of the balls are installed.



19. Insert approximately 60 percent of the grease from the service kit into the outer joint.

19.1.

Spread 60 percent of the grease onto the ball tracks, the balls, the cage and the inner race.

19.2.

Spread the remainder of the grease into the bottom of the outer race.

20. Remove the outer joint from the bench vise.



21. Wrap a shop towel around the axle shaft.
22. Place the wheel drive shaft horizontally in a bench vise.
23. Install a new small seal retaining clamp onto the axle shaft.
24. Install the seal onto the axle shaft.



25. Install a new retaining ring to the axle shaft.



26. Position the outer joint horizontally.
27. Engage the inner race splines onto the axle shaft splines.
28. Compress the axle shaft retaining ring.

28.1.

Press the end of the retaining ring, using a flat-bladed tool, into the axle shaft groove while firmly pressing the outer joint onto the axle shaft.

28.2.

Continue to work around the retaining ring, until it is compressed.





Important: The axle shaft and inner race must be fully seated to each other.

29. Install the outer joint to the axle shaft.

29.1.

Position a wood block over the end of the outer joint threaded shaft.

29.2.

Use a hammer to drive the outer joint onto the shaft.

29.3.

Continue to drive the outer joint until the outer joint seats fully onto the axle shaft.




30. Insert the remaining grease from the service kit into the seal.



31. Position the small seal retaining clamp (2) into the boot groove.
32. Position the boot and small retaining clamp to the axle shaft boot groove (3) as shown.

Notice: Refer to Fastener Notice in the Preface section.





Important: The seal retaining clamp must not be over-tightened or under-tightened.

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

Tighten
Tighten the small seal clamp until there is a gap of 1 mm (0.039 in).




34. Position the large seal retaining clamp (1) onto the seal (2).
35. Position the seal and large retaining clamp to the joint outer race (3) as shown.




Important: The seal must not be dimpled, stretched or otherwise deformed.

36. Inspect the boot for proper shape.

If the boot is not shaped correctly, equalize the pressure in the boot by lifting the boot edge slightly and shape the properly by hand.

37. Inspect the boot for damage.

If the boot has been cut or punctured during assembly, you must discard and replace the boot.

Important: The seal retaining clamp must not be over-tightened or under-tightened.

38. Using the J 42572 , crimp the large seal retaining clamp.

Tighten
Tighten the large seal clamp until there is a gap of 1 mm (0.039 in).

The clamping hold time must be no less than 2 seconds.

39. Inspect the outer joint for smooth operation. This will also distribute the grease within the joint.

39.1.

Hold the wheel drive shaft vertically, with the outer joint at the bottom.

39.2.

Rotate the wheel drive shaft 4 or 5 times in a circular motion.
