For the Opel Astra G chassis, RUVILLE offers a diverse product range that was nearly completed with the introduction of chassis springs for the front and rear axle. During repair work, both general as well as specific procedures have to be followed for the respective components.

Vehicle-specific installation instructions:

For some chassis components and for the wheel bearings in the Opel Astra G, specific installation instructions have to be followed. These are described in more detail below. The relevant articles are highlighted in grey in the table.

OPEL ASTRA G

CHASSIS

Basic installation instructions:

Use self-locking nuts, replace them as needed. In general, replacing the bolts and screws is always recommended. Comply with the tightening torques specified in the manufacturer’s

specifications. Tighten steering components under load. Following work on the chassis, it is always advisable to measure the

chassis; in the case of some repairs, it is also mandatory. Use the designated special tools.

Before dismantling the suspension strut, mark the positioning and installation position of the individual components. Springs and shock absorbers must always be repla-ced in pairs. If the suspension strut is only removed, and not dismantled, the attachment nut for the support mounting on the shock absorber piston rod must be che-cked before installation using the specified tightening torque. Check the camber and adjust if necessary.

Article: 985365 | Axle body mounting

To make it easier to remove the dam-ping bushes, they should be sprayed with universal spray oil in the area of the rear axle mounting one day before removal. The damping bushes of the rear axle must always be replaced in pairs.The bolt connection (rear axle holder at damping bush) is tightened during installation of the rear axle, while main-taining the correct spacing between the spring mounting on the rear axle and the spring mounting on the vehicle underbody.

If the steering mounting has to be replaced, the air supply, if applicable, must be converted (retrofitted).Before tightening the bolts, lower the vehicle to the floor, load both front seats with 70 kg each and tighten the bolt connections for the steering mountings at the front axle on the inspection stand or in the pit.The bearing bushes must be replaced in pairs. Before pressing in, coat the bearing bushes and mountings with soap solution. Fit the rear bearing bush (4) up against the mounting so that the weld seam is aligned with one of the recesses in the bush (arrows).

Article: 915355 | Support/guide joint

Before replacing the support joint, drill out the rivet heads (1) using a drill with a 12 mm diameter bit. Drill out the rivets as far as the support surface (guideline) of the guide, then tap off carefully using a flat chisel and remove the remains of the rivets.Remove the guide joint and coat the bore with corrosion protection. New special bolts are supplied with the new support joint, which in all cases must be used for the installation (mandatory)! Insert the special bolts as shown in Fig. 2.

Measure the lateral run-out:Installation of the test device:Fit the test gauge (3) with test gauge holder (2) and magnet (4) to the backing plate or cover plate. Place the probe tip (1) of the test gauge against the outer edge of the bearing unit, and turn the wheel bearing unit slowly.

Measurement result:Permissible lateral run-out max. 0.04 mm. If the result deviates from this set value, replace the wheel bearing unit.

Measure the radial run-out:Installation of the test device:Fit the test gauge (3) with test gauge holder (2) and magnet (4) to the backing plate or cover plate. Place the probe tip (1) of the test gauge against the bearing unit (as in Fig. 2), and turn the wheel bearing unit slowly.

Measurement result:Permissible radial run-out max. 0.05 mm. If the result deviates from this set value, replace the wheel bearing unit.

To replace the stabiliser bushes, the front axle must be lowered. The axle may only be lowered to a maximum permissible distance of 55 mm.Before fitting the new bearing bushes, a special lubricating grease must be applied to the inner surfaces (not supplied). The slot in the bushes must point forward in the direction of travel.
