Rear Anti-Roll Bar (DOHC Models) — Removal and Installation (Opel Vectra A)

Removal

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

2. Working under the rear of the vehicle, remove the brackets and release the brake lines from the brackets on both sides of the vehicle's underbody. Note that the brackets also support the ABS sensor wires.

3. Disconnect the fuel outlet hose from the fuel filter located on the right side of the underbody in front of the fuel tank. Plug the open holes in the filter and hose to prevent further fuel loss and dirt from entering the system.

4. Support the rear plate of the suspension cross member with a jack, then unscrew and remove the two bolts securing the rear cross member beam.
