• Torque Wrench 1332 40-200Nm -VAG1332-
• Engine and Gearbox Jack -VAS6931-
• Engine/Gearbox Jack Adapter - Wheel Hub Support -T10149-
• Torque Wrench 1331 5-50Nm -VAG1331-
• Drive Shaft Remover -T10520-

Removing

• Loosen drive axle bolt on the wheel hub.
• Remove the wheel.
• Remove the level control system sensor from the control arm.
• Remove the nut -arrow- of the connecting link from suspension strut.

• Remove the nuts -arrows-.
• Remove the wheel bearing housing with the ball joint from the control arm.
• 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 -T10520-.

Before using the Drive Shaft Remover -T10520-, make sure that the thrust piece -1- is installed.

Using the Drive Shaft Remover -T10520-:

• Secure the Drive Shaft 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 exactly.

1. Tighten the knurled nut -1- hand-tight.
2. Only turn the bolt -2- using a wrench and press out the drive axle using the Drive Shaft Remover -T10520-.

Note

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 wire.

Note

The drive axle must not hang down, otherwise the inner joint will be damaged by over bending.

• Bolt the ball joint to the control arm again.
• Secure the Engine and Gearbox Jack -VAS6931- using the Engine/Gearbox Jack Adapter - Wheel Hub Support -T10149- to the wheel hub with a wheel bolt.

• Disconnect the connector and remove the wire from the suspension strut

• Disconnect the threaded connection for the wheel bearing housing/suspension strut nut -arrow-.

• Insert Spreader Tool -3424- into wheel bearing housing slot.
• Turn the ratchet 90º and remove it from the Spreader Tool -3424-.
• Press the brake rotor toward the suspension strut by hand.

Otherwise strut tube may be canted in hole of wheel bearing housing.

• Pull off wheel bearing housing downward from strut tube and lower using Engine/Gearbox Jack -VAG1383A- as far until strut tube hangs freely.
• Tightly tie wheel bearing housing to console/subframe using binding wire.
• Remove the Engine and Gearbox Jack -VAS6931- from under the wheel bearing housing.

One of two markings -arrows- on the spring plate must point in the direction of travel.

Left Suspension Strut

The suspension strut must be installed so that the Left Front Damping Adjustment Valve -N336- faces opposite the drive direction.

Right Suspension Strut

The suspension strut must be installed so that the Right Front Dampening Adjustment Valve -N337- faces opposite the drive direction.

Continuation for Both Sides

• Check the installation position of the Left and Right Front Body Acceleration Sensor -G341/G342- retainer.
