Installing

Install in reverse order of removal. Note the following:

The bolted connections of the shock absorber to the wheel bearing housing must only be fastened when the dimension "a" is achieved! Refer to => [ Tightening of the respective bolts/nuts must then only occur after dimension between the wheel hub center and the lower edge of wheel housing has been attained. ] See: Suspension > Components > Rear Axle, Lifting to Curb Weight Position.

Note the shock absorber installation position.

Here are the directions for the front strut assemblies / removal and replacement. The remaining pictures correlate with these directions.

Suspension Strut

Special tools, testers and auxiliary items required

Torque Wrench 1332 40-200Nm (VAG1332)

Spreader Tool Tool (3424)

Engine/Gearbox Jack (VAG1383A)

Engine/Gearbox Jack Adapter - Wheel Hub Support (T10149)

Adaptive chassis DCC suspension strut, removing and installing, refer to => [ Suspension Strut ] See: Suspension Strut / Shock Absorber > Removal and Replacement > Suspension Strut.

Removing

- Loosen drive axle bolt to wheel hub:

Twelve-point bolt with ribs, refer to => [ Drive Axle Twelve-Point Bolt with Ribs, Loosening and Tightening ] See: Axle Nut > Procedures > Drive Axle Twelve-Point Bolt With Ribs, Loosening and Tightening.

Twelve-point bolt without ribs, refer to => [ Drive Axle Twelve-Point Bolt without Ribs, Loosening and Tightening ] See: Axle Nut > Procedures > Drive Axle Twelve-Point Bolt Without Ribs, 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's own 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.

- Remove the wheel.

- Remove the nut - arrow - of the connecting link from suspension strut.

Pic 8

- Disengage wire for wheel speed sensor from suspension strut.

- Remove the level control system sensor from the control arm.

Pic 9

- Remove the nuts - arrows -.

Pic 10

- Remove both the wheel bearing housing and ball joint from the control arm.

- Remove the drive axle outer joint from the wheel hub.

- Secure drive axle to body using wire.

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

- Bolt ball joint to control arm again.

- Fasten Engine/Gearbox Jack (VAG1383A) using Engine/Gearbox Jack Adapter - Wheel Hub Support (T10149) to wheel hub with a wheel bolt.

Pic 11

Do not lift or lower vehicle when the Engine/Gearbox Jack (VAG1383A) stands below the vehicle. Vehicle could slip off lift.

Do not leave Engine/Gearbox Jack (VAG1383A) below vehicle any longer than necessary.

- Disconnect threaded connection of wheel bearing housing/suspension strut - arrow -.

Pic 12

- Insert Spreader Tool Tool (3424) into slot of wheel bearing housing.

Pic 13

- Using a ratchet and the Spreader Tool Tool (3424), open the wheel bearing housing slot.

- Press brake disc in direction of 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 Engine/Gearbox Jack (VAG1383A) from below wheel bearing housing.

Do not leave Engine/Gearbox Jack (VAG1383A) below vehicle any longer than necessary.

- Remove wiper arms.

- Remove plenum chamber cover.

- Remove the bolts - arrows - for upper strut mount and remove suspension strut.

Pic 14

Installing

- Secure Engine/Gearbox Jack (VAG1383A) with Engine/Gearbox Jack Adapter - Wheel Hub Support (T10149) to wheel hub using a wheel bolt.

Pic 15

- Attach suspension strut to wheel bearing housing and secure suspension strut using socket head bolt and new nut.

Socket head bolt tip must point in direction of travel.

- Remove Engine/Gearbox Jack Adapter - Wheel Hub Support (T10149).

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

Pic 16

- Remove wire on wheel bearing housing.

- Carefully lift the wheel bearing housing using the transmission jack enough so that the suspension strut/strut tower bolts - arrows - can be installed.

Pic 17

If necessary, use ladder, for example the Step Ladder (VAS5085) to install bolts.

- Tighten bolts for upper strut mounting - arrows -.

- Remove Engine/Gearbox Jack Adapter - Wheel Hub Support (T10149).

- Tighten threaded connection of wheel bearing housing/suspension strut - arrow -.

Pic 18

- Remove the nuts - arrows -.

Pic 19

- Insert drive axle into wheel hub.

- Insert wheel bearing housing with ball joint into control arm.

- Attach the ball joint to the control arm - arrows -.

Make sure that the ball joint boot is not damaged or twisted.

- Tighten drive axle bolt to wheel hub:

Twelve-point bolt with ribs, refer to => [ Drive Axle Twelve-Point Bolt with Ribs, Loosening and Tightening ] See: Axle Nut > Procedures > Drive Axle Twelve-Point Bolt With Ribs, Loosening and Tightening.

Twelve-point bolt without ribs, refer to => [ Drive Axle Twelve-Point Bolt without Ribs, Loosening and Tightening ] See: Axle Nut > Procedures > Drive Axle Twelve-Point Bolt Without Ribs, Loosening and Tightening.

Vehicle must not rest on wheels when doing so.

With bolt loosened, wheel bearing can be damaged by vehicle's own weight.

- Install plenum chamber cover.

- Install wiper arms.

Further installation is in the reverse sequence to removal.

- Install the wheel and tighten the wheel bolts. Refer to => [ Wheel Bolt Tightening Specification ] See: Wheel Stud / Lug Nut > Mechanical > Wheel Bolt Tightening Specification.
