CAUTION:

Do not load the wheel bearing if the wheel-side drive axle threaded connection is loose.

If the wheel bearings are under the load of the vehicle weight, the wheel bearing will be damaged. This reduces the service life of the wheel bearings.

The drive axle bolt may be loosened maximum 90° when the vehicle is standing on its wheels.

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If a vehicle must be moved, be sure to note the following:

Install an outer joint in place of the drive axle.
Tighten the outer joint to 120 Nm.

Twelve-Point Bolt, Loosening

-- With vehicle still resting on wheels, loosen the twelve-point bolt with :T10361A maximum 90°, otherwise, wheel bearing will be damaged.

-- Lift the vehicle just enough so that the wheels are hanging free.

-- Press the brake pedal. A second technician will be needed.

-- Remove the twelve-point bolt -arrow-.
