REAR DRIVE SHAFT
Revision: November 20092006 QX56
5. Separate the drive shaft from the wheel hub and bearing assembly by lightly tapping the end with a suit-
able hammer and wood block. If it is difficult to separate, use a suitable puller.
6. Remove the drive shaft. CAUTION:
When removing the drive shaft, do not bend at an excessive angle to the drive shaft joint. Do not
excessively extend the slide joint.
INSPECTION AFTER REMOVAL

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

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

If necessary, disassemble the drive shaft, and repair as neces-
sary.
