CAUTION: Use paint or similar substance for matching marks. Do not scratch the surface.

7. Remove snap ring, then remove ball cage, steel ball and Inner race assembly from shaft.
8. Remove boot from shaft.
9. Remove old grease on housing with paper towels.

Wheel Side
1. Remove dust shield from drive shaft.
2. Secure shaft in a vise.

CAUTION: Protect shaft when securing in a vise using aluminum or copper plates.

3. Remove boot bands. Then remove boot from joint sub-assembly.

4. Screw a drive shaft puller 30 mm (1.18 inch) or more into threaded part of joint sub-assembly Pull joint sub-assembly out of shaft.

CAUTION:
^ If joint sub-assembly cannot be removed after five or more unsuccessful attempts, replace shaft and joint sub assembly as a set.
^ Align sliding hammer and drive shaft and remove them by pulling directory.

5. Remove boot from shaft.
6. Remove circular clip from shaft.
7. While rotating ball cage, remove old grease on joint sub-assembly with paper towels.

INSPECTION AFTER DISASSEMBLY
Shaft
Replace shaft if there is any runout, cracking, or other damage.

Joint Sub-Assembly (Wheel Side)
Check the following:
^ Joint sub-assembly for rough rotation and excessive axial looseness.
^ The inside of the joint sub-assembly for entry of foreign material.
^ Joint sub-assembly for compression scars, cracks, and fractures inside of joint sub-assembly.

Replace joint sub-assembly if there are any non-standard conditions of components

CAUTION: If there are any irregular conditions of joint sub-assembly components, replace the entire joint sub-assembly.

Final Drive Side
^ Make sure there are compression scars, cracks, fractures or unusual wear of ball rolling surface.
^ Make sure there is no damage to shaft screws.
^ Make sure there is no deformation of boot installation parts.

Ball Cage
Make sure there are compression scars, cracks, fractures of sliding surface.

Steel Ball
Make sure there are compression scars, cracks, fractures or unusual wear.

Inner Race
^ Check ball sliding surface for compression scars, cracks or fractures.
^ Make sure there is no damage to serrated part.

CAUTION: If there are any irregular conditions in the component, replace with a new set of housing and the ball cage, steel ball and inner race assembly.

ASSEMBLY
Final Drive Side

1. If plug has been removed, use a drift [SST] to press in a new one.

CAUTION: Do not reuse plug.

2. Wrap serrated part of shaft with tape. Install boot band and boot to shaft. Be careful not to damage boot.

CAUTION: Do not reuse boot band and boot.

3. Remove protective tape wrapped around serrated part of shaft.

4. Install ball cage, steel ball and inner race assembly to shaft, and secure them tightly with a snap ring.

CAUTION: Do not reuse snap ring.

NOTE: Align matching marks painted when ball cage, steel ball and inner race assembly were removed.

5. Apply the specified amount of grease (NISSAN genuine grease or equivalent) onto housing (* point) and install it to shaft.

NOTE: Align matching marks painted when housing were removed.

Grease amount
VQ35DE model: 130 - 150 grams (4.59 - 5.29 ounces)
VK45DE model: 155 - 175 grams (5.47 - 6.17 ounces)

6. Install stopper ring to housing.
7. After installed, pull shaft to check engagement between joint sub-assembly and stopper ring.

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

CAUTION: If there is grease on boot mounting surfaces (indicated by * marks) of shaft and housing, boot may come off. Remove all grease from the surfaces.

9. Make sure boot installation length "L" is the length indicated below. Insert a flat-bladed screwdriver or similar tool into inside of boot from the large diameter side of boot. Bleed air from boot to prevent boot deformation.
Boot installation Length "L"
VQ35DE model: 145 mm (5.709 inch)
VK45DE model: 148 mm (5.827 inch)

CAUTION:
^ Boot may break if boot installation length is less than standard value.
^ Take care not to touch the tip of screwdriver to inside of boot.

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

CAUTION: Do not reuse boot band.

11. After installing housing and shaft, rotate boot to check whether or not the actual position is correct. If boot position is not correct, secure boot with new boot band again.

Wheel Side

1. Apply the specified amount of grease (NISSAN genuine grease or equivalent) into joint sub-assembly serration hole until grease begins to ooze from ball groove and serration hole. After applying grease, use a shop cloth to wipe off old grease that has oozed out.

4. Attach circular clip to shaft. At this time, circular clip must fit securely into shaft groove. Attach nut to joint sub-assembly. Use a wooden hammer to press-fit.

CAUTION: Do not reuse circular clip.

5. Apply the specified amount of grease (NISSAN genuine grease or equivalent) into housing from large end of boot.
Grease amount
VQ35DE model: 115 - 135 grams (4.06 - 4.76 ounces)
VK45DE model: 155 - 175 grams (5.47 - 6.17 ounces)

6. Install boot securely into grooves (indicated by * marks) shown in the figure.

CAUTION: If there is grease on boot mounting surfaces (indicated by marks) of shaft and housing, boot may come off. Remove all grease from the surfaces.

7. Make sure boot installation length "L" is the length indicated below. Insert a flat-bladed screwdriver or similar tool into inside of boot from the large diameter side of the boot. Bleed air from boot to prevent boot deformation.
Boot installation Length "L
VQ35DE model: 136 mm (5.354 inch)
VK45DE model: 145 mm (5.709 inch)

CAUTION:
^ Boot may brake if boot installation length is less than standard value.
^ Be careful that screwdriver tip does not contact inside surface of boot.

8. Secure large and small ends of boot with new boot bands as shown in the figure.

CAUTION: Do not reuse boot band.

9. After installing joint sub-assembly and shaft, rotate boot to check whether or not the actual position is correct. If boot position is not correct, secure boot with new boot bands again.
10. Install dust shield to drive shaft.

CAUTION: Do not reuse dust shield.
