8 Push rear axle shaft out of rear axle shaft flange
CAUTION: Do not damage rubber sleeves or rotor for speed sensor

DANGER: Risk of fatal accident if vehicle slips off of lifting platform
Align vehicle between the columns of the lifting platform and position the four support plates at the lifting platform support points specified by the vehicle manufacturer
9 Detach rear axle shafts (37) from connecting flange
NOTE: Move rear axle shaft so that is roughly horizontal, push together and remove from connecting flange angled downwards
When slackening locking bolts ensure that screwdriver bit is inserted correctly into multi-point or hexagon profile, clean if necessary
CAUTION: To avoid damaging the wheel bearing, the vehicle must not be moved on its wheel with the rear axle shaft removed

Lightly oil bolts at thread and bolt head contact surface.
10 Check constant velocity joints, rubber boots and end cover for leaks and damage
CAUTION: If outside constant velocity joint is defective, replace complete rear axle shaft
If inner constant velocity joint is defective or if rubber boots and end covers are damaged or leaking, replace appropriate parts
Removing and installing inner constant velocity joint or rubber boots on rear axle shaft
