Wheel Bearing Housing: Removing
-- Remove the drive axle bolt. Refer to THREADED CONNECTION, LOOSENING AND TIGHTENING .
The wheel bearing must not be under a load while the drive axle threaded connection on the wheel side 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.
-- Loosen the wheel bolts.
-- Raise the vehicle.
-- Remove the wheel.
-- Remove the brake caliper and tie it to the vehicle body with wire. Refer to Removal and Installation .
-- Disconnect the connector -1- from the ABS speed sensor.
-- Remove the bolt -arrow- and the ABS speed sensor -1-.
-- Remove the brake rotor -1- -arrow-.
-- Remove the cover plate -1- from the wheel bearing housing -arrow-.
-- Loosen nut of track rod ball joint, but do not unscrew yet.
To protect thread, screw nut on pin a few turns.
-- Remove the tie rod from the wheel bearing housing and remove the nut.
- Ball Joint Puller T10187
-- Loosen nuts -arrows-.
-- Remove the control arm from the ball joint.
-- Remove the drive axle outer joint from the wheel hub.
If the Drive Axle Cannot be Pulled Out of the Wheel Bearing, Then it Can Be Pushed Out of the Wheel Bearing Using the Remover T10520.
Before using the Remover T10520 pay attention that the thrust piece -1- is installed.
Using the Remover T10520:
-- Secure the Remover T10520 -1- with three wheel bolts -2- on the wheel hub, so that the drive axle -3- can be pressed out.
-- Follow the specified sequence.
I - Tighten the knurled nut -1- hand-tight.
II - Turn only the bolt -2- with a wrench and press out the drive axle with the Remover T10520.
At the end of the tasks or to set back, the spindles must be brought back into the original position so that the hydraulic operation can be used.
-- Secure drive axle to body using wire.
-- Move the Engine/Gearbox Jack VAG1383A under the wheel bearing housing.
-- Remove threaded connection of wheel bearing housing/suspension strut -arrow-.
-- Insert Spreader Tool 3424 into slot of wheel bearing housing.
-- Turn the ratchet 90° and remove it from the Spreader Tool 3424.

If the wheel bearing housing is being replaced, then the ball joint must also be replaced. Use new nuts.
