Removal and installation rear suspension coil springs (Opel Astra G)

Due to the design features of the suspension, the rear springs can only be replaced one at a time. The springs must be replaced as a set.

Removal

1. Support the front wheels with wheel chocks, jack up the rear of the car and place it on supports. Remove the rear wheels.

2. On station wagon models, equipped with a rear ride height adjustment system, remove the cover of the right rear combination lamp in the luggage compartment and release the pressure from the system through the valve. Disconnect the air tube from the shock absorber.

3. Support the corresponding longitudinal arm of the rear beam with a trolley jack.

4. Unscrew the lower bolt securing the shock absorber to the lever.



5. Carefully press the trailing arm down as far as possible without putting any load on the brake line.

6. Remove the spring and its rubber seats from the trailing arm and body element and remove the components from under the vehicle (see illustration Rear suspension design), - note that the upper saddle is equipped with a built-in bumper.

Installation

Installation is performed in the reverse order of dismantling the components. Please note the following points.



1. Before installing the shock absorber, make sure that the spring and spacers are installed correctly.

2. Make sure that the shock absorber fasteners are tightened to the required torque.

3. Remember that the springs must be changed in pairs - repeat the procedure for the second spring.

4. On models equipped with rear ride height adjustment system, charge the system with air pressure of 0.8 bar, then adjust the pressure according to the vehicle loading degree.
