Removing

CAUTION!
Before starting work, stabilizer bars must be coupled in vehicles with separable stabilizer bars. Otherwise, there is the danger of injury caused by unintentional separation.

During assembly work, make sure that no indentations form on boot of air spring shock absorber!

- Remove wheel.

- Remove air line from air spring shock absorber and seal both connections.

- Engage upper control arm to body using tensioner hooks (VW 552) and pre-tension lightly.





- Disconnect connector from left front level control system sensor (G78).

- Remove coupling rod from stabilizer bar.

- Disconnect driveshaft from rear final drive. Use socket, nominal size 14 mm (T10099/1) for loosening bolts.

- Remove plenum chamber cover.

Removing Left Air Spring Shock Absorber

- Remove bolt - arrow - beneath reservoir - 1 - for brake fluid.





- Remove bolts- arrow - beneath reservoir - 1 - for hydraulic fluid.





Removing Right Air Spring Shock Absorber

- Disengage harness connector from Engine Control Module (ECM) - 2 - and disconnect it.





- Remove control module.

- Remove bracket for ECM - 2 -.

Bolts for bracket (quantity: 3) are now accessible.

- Remove bolt - arrow -.





- Remove bolts - arrows -.





Continuation for Both Sides

- Turn wheel hub far enough until one of the holes for wheel bolts is on top.

- Install wheel hub support (T10149) with wheel bolt.





- Press off tie rod from wheel bearing housing.





- Press out upper control arm.





- Remove bolt of air spring shock absorber to lower control arm.

- Do not lower wheel bearing housing more than necessary.





- Remove bolt from lower control arm and remove air spring shock absorber.

Installing

Installation is the reverse of removal, with special attention to the following:

If a new air spring shock absorber is installed, it must first be filled. Refer to --> [ Air Spring Damper, Filling ] Air Spring Damper, Filling.

• Pin for mounting wheel speed sensors is no longer present on new air spring shock absorbers.

• Vehicles with Vehicle Identification Numbers (VIN) up to 7L-4-052999 are still equipped with wheel speed sensors - 1 - on fork. This sensor must be reused when installing new shock absorber.





• To do so, the sensor must be installed on new shock absorber using a new bolt. Note installation position as shown in illustration.

- Check basic setting of level control system. Refer to --> [ Level Control System Basic Setting ] Level Control System Basic Setting.

- Install wheel and tire. Refer to --> [ Wheel Bolts, Tightening Specification ] .

- After installation, a vehicle alignment must be performed. Refer to --> [ Wheel Alignment ] Wheel Alignment.
