2. Remove the appropriate wheel.
3. On models not equipped with brake pad wear sensors, move the locking pin (see accompanying illustration) down and disconnect the ABS sensor wiring connector. On models with brake pad wear sensors, first move the first locking tab down, then turn the second locking tab in the direction indicated by the arrow and disconnect the ABS sensor wiring connector.
Note: On models with Automatic Level Control (CDC), 4 wiring connectors must be disconnected.
4. On CDC equipped models, remove the sensor and holder from the shock absorber strut.
5. Remove the wire from the shock absorber strut.
6. Release the brake hose from the holder on the shock absorber strut (see Chapter 9).
7. Loosen the upper mounting nut (see accompanying illustration) stabilizer bar struts, holding the strut mounting axle from turning with a second wrench. Remove the axle and strut.
8. Mark the position of the lower mounting bolts (see illustration 2.7) on the steering knuckle, for which we trace their heads with a marker.
Attention: When installing, the bolts must be installed strictly in the same place - if the position of the bolts changes, the camber of the wheels will change!

9. Remove the lower shock absorber strut mounting bolts from the steering knuckle and push the steering knuckle outward,
10. Ask an assistant to support the shock absorber strut from below.
11 Open the hood. Using a special tool (see accompanying illustration) remove the retaining ring from the upper shock absorber cover and remove the shock absorber from the front wheel arch.
Note: The retaining ring will be damaged during removal and must be replaced without fail.
12. Installation is carried out in the reverse order of removal. When installing a new retaining ring (it consists of two semi-rings) it must be compressed using a special device Opel KM-6384. To fasten the shock absorber strut, it is necessary to use self-locking bolts and nuts - the bolts must be inserted from the front. When installing, it is necessary to align the bolt heads with the previously applied marks. In 3 steps, tighten the shock absorber strut mounting bolts with the required force (see Specifications).
Note: If the camber adjustment is performed immediately after installing the shock absorber strut, first tighten the connection to 50 Nm and then tighten it completely after adjustment.
At service stations, a special HAZE 6690 template is used to check the wheel alignment angle; for individual use, you can cut out a corresponding template from thick cardboard.
13. If the strut was removed outside a service workshop, check the wheel alignment at a service station as soon as possible.
Caution: The lower self-locking mounting bolts and nuts of the shock absorber strut must be replaced after each time they are loosened! It is recommended to always have a spare set of bolts and nuts in the car.
