CAUTION:
When removing drive shaft, do not apply an excessive angle to drive shaft joint. Also be careful
not to excessively extend slide joint.
INSPECTION AFTER REMOVAL

Move joint up/down, left/right, and in the axial direction. Check
for any rough movement or significant looseness.

Check boot for cracks or other damage, and also for grease
leakage.

If a trouble is found, disassemble drive shaft, and then replace
with new one.

secure boot with new boot band again.
Wheel Side
1. Insert the amount of grease (NISSAN genuine grease or equiva-
lent) into joint sub-assembly serration hole until grease begins to
ooze from ball groove and serration hole. After insert grease,
use a shop cloth to wipe off old grease that has oozed out.
2. Wind serrated part of shaft with tape. Install boot band and boot
to shaft. Be careful not to damage boot.
NOTE:
Discard old boot band and boot; replace with each new one.
