Rear suspension coil spring (single overhead camshaft (SOHC) models). — removal and installation (Opel Vectra A)

Removal

1. Due to the design of the rear suspension on these models, both springs cannot be removed at the same time. Please note that the rear springs should be replaced in pairs. When replacing the springs, it is recommended to replace their rubber buffers at the same time.

2. On models with manual rear suspension damping control, relieve pressure in the system by releasing air through the valve in the luggage compartment.

3. Block the front wheels, then jack up and support the rear of the vehicle on axle stands.

4. Slightly raise the corresponding trailing arm using a jack.

5. Loosen and remove the bolt and washer securing the lower end of the shock absorber to the trailing arm and release the lower end of the shock absorber.

6. Carefully lower the jack supporting the trailing arm and remove the spindle spring and rubber buffers. If necessary, move the trailing arm down slightly to remove the spring.

Installation

7. Install in reverse order, making sure the spring is correctly positioned on the trailing arm and underbody.

8. Tighten the lower shock absorber mounting bolt to the specified tightening torque Specifications.

9. If the springs need to be replaced, repeat the procedure on the opposite side of the vehicle.

10. On models with manual rear suspension stiffness control, increase the pressure in the system to 0.8 bar.
