Wheel Bearing Housing, Removing And Installing: Removing
The following information describes the removing and installing on the left side of the vehicle as an example.
The Left Front ABS Wheel Speed Sensor -G47- and Right Front ABS Wheel Speed Sensor -G45- will be called front speed sensor in the information that follows.
-- Remove the drive axle bolt. Refer to DRIVE AXLE THREADED CONNECTION, LOOSENING AND TIGHTENING .
Damage to the wheel bearing from the vehicle weight with the wheel-side drive axle threaded connection loose.
- Do not load the wheel bearing if the wheel-side drive axle threaded connection is loose.
- Vehicles without drive axle may not be moved when resting on its wheels. Otherwise the wheel bearing will be damaged. If the vehicle has to be moved, pay attention to the following: install the outer joint. 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 OVERVIEW - FRONT BRAKES .

-- Remove the brake rotor. Refer to OVERVIEW - FRONT BRAKES .
-- Remove and free up the brake line bracket and wires from the wheel bearing housing.
-- Remove the cover plate -1- from the wheel bearing housing -arrow-.
-- Loosen the nut from the tie rod end, but do not remove it yet.
There is a risk of damaging the wheel bearing housing with loosened bushings if the ball joint puller is positioned incorrectly.
The ball joint puller must be supported on the bushing and not on the wheel bearing housing.

-- 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 the drive axle can be pushed out of the wheel bearing using the Drive Shaft Remover:T10520A .
Before using the Drive Shaft Remover:T10520A , make sure that the thrust piece -1- is installed.
Using the Drive Shaft Remover: T10520A :
-- Attach the Drive Shaft Remover:T10520A -1- to the wheel hub using three wheel bolts -2-. Press out the drive axle -3-.
-- Follow the specified sequence exactly.
I - Tighten the knurled nut -1- hand-tight.

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 the drive axle to the body using a wire.
-- Position the Engine and Gearbox Jack:VAS 6931 under the wheel bearing housing.
-- Remove the threaded connection on the wheel bearing housing/suspension strut -arrow-.
-- Insert Spreader Tool:3424 into the wheel bearing housing.
Pay attention that the Spreader Tool:3424 is only inserted in the wheel bearing housing. Only insert it far enough that the suspension strut metal retainer is not damaged.
