DISASSEMBLY

Final Drive Side
1. Secure the drive shaft in a vise.

CAUTION:
When securing the drive shaft in a vise, use copper or aluminum plates between the vise and the drive shaft.
2. Remove the boot bands.
3. If the plug needs to be removed, move the boot to the wheel side, then drive the plug out using a suitable tool.





4. Remove the stopper ring using a suitable tool as shown, and pull the housing out.
5. Remove the snap ring using a suitable tool, then remove the ball cage, steel ball, inner race assembly from the drive shaft.





6. Remove the boot from the drive shaft.
7. Remove any old grease on the housing using paper towels.

Wheel Side
1. Secure the drive shaft in a vise.

CAUTION:
When securing the drive shaft in a vise, use copper or aluminum plates between the vise and the drive shaft.
2. Remove the boot bands, then remove the boot from the joint sub-assembly.





3. Screw a suitable drive shaft puller 30 mm (1.18 in) or more into the threaded part of the joint sub-assembly. Pull the joint subassembly out of the drive shaft as shown.

CAUTION:
- If the joint sub-assembly cannot be removed after five or more attempts, replace the drive shaft and joint subassembly as a set.
- Align the sliding hammer and drive shaft and remove the joint sub-assembly by pulling directly.
4. Remove the boot from the drive shaft.
5. Remove the circlip from the drive shaft.
6. While rotating the ball cage, remove any old grease on the joint sub-assembly using paper towels.

INSPECTION AFTER DISASSEMBLY

Drive Shaft
- Replace the drive shaft if there is any runout, cracking, or other damage.

Joint Sub-assembly
- Check for any rough rotation or unusual axial looseness.
- Clean any foreign material from inside the joint sub-assembly.
- Check for any compression scars, cracks, or fractures.

CAUTION:
If any defective conditions are found in the joint sub-assembly components, replace the entire joint sub-assembly.

Sliding Joint Side (Housing)
- Check for any compression scars, cracks, fractures, or unusual wear on the ball rolling surface.
- Check for any damage to the drive shaft screws.
- Check for any deformation of the boot installation components.

Ball Cage
- Check the sliding surface for any compression scars, cracks, or fractures.

Steel Ball
- Check for any compression scars, cracks, fractures, or unusual wear.

Inner Race
- Check the ball sliding surface for any compression scars, cracks, or fractures.
- Check for any damage to the serrated part.

CAUTION:
If any defective conditions are found, install a new housing, ball cage, steel ball, and inner race as a set.

ASSEMBLY

Final Drive Side
1. If the plug has been removed, use Tool to press in a new one.











NOTE:
Discard the old plug and use a new one for assembly.





2. Wrap the serrated part of the shaft with tape. Install the boot band and boot to shaft.

NOTE:
Discard the old boot band and boot and use a new one for assembly.
3. Remove the tape wound around the serrated part of the shaft.





4. Install the ball cage, steel ball, and inner race assembly on the shaft, and secure them tightly using the snap ring.

NOTE:
Discard the old snap ring and use a new one for assembly.





5. Insert the specified quantity of Genuine NISSAN Grease or equivalent, onto the housing (indicated by * marks), and install it onto shaft. Refer to Maintenance.

Grease capacity : 175 - 195 g (6.17 - 6.88 oz)

7. After installation, pull on the shaft to check engagement between the joint sub-assembly and the stopper ring.





8. Install the boot securely into the grooves (indicated by * marks) as shown.

CAUTION:
If there is grease on boot mating surfaces (indicated by*
marks) of shaft and housing, boot may come off. Remove all grease from surfaces.
9. Check that the boot installation length "L" is the length indicated below. Insert a suitable tool into large side of the boot. Bleed the air from the boot to prevent any boot deformation.

Boot installation length "L" : 147.9 mm (5.82 in)

CAUTION:
- The boot may break if the boot installation length is less than the specified value.
- Do not to touch the tip of the tool to the inside of the boot.





10. Secure the large and small ends of the boot with the new boot bands as shown.

NOTE:
Discard the old boot bands and use new ones for assembly.
11. After installing the housing and shaft, rotate the boot to check that the boot is positioned correctly. If the boot is not positioned correctly, reposition the boot and secure the boot using a new boot band.

Wheel Side
1. Insert the Genuine NISSAN Grease or equivalent, into the joint sub-assembly serration hole until the grease begins to ooze from the ball groove and serration hole. Refer to Maintenance. After inserting the grease, use a shop cloth to wipe off the grease that has oozed out.

NOTE:
Discard the old boot band and boot and use a new one for assembly.





3. Remove the protective tape wound around the serrated part of the shaft.
4. Attach the circlip to the shaft. The circlip must fit securely into the shaft groove. Attach the nut to the joint sub-assembly.





Use a suitable tool to press-fit the circlip.

NOTE:
Discard the old circlip and use a new one for assembly.
5. Insert the specified quantity of Genuine NISSAN Grease or equivalent, into the housing from the large end of the boot. Refer to Maintenance.
