General description (Audi 100 C3)

The front suspension is independent. It has a coil spring, a strut and a lower arm. The struts are connected to telescopic shock absorbers. Both front suspension units are mounted on the lower frame. The anti-roll bar is attached to the arms and also provides localization of each strut assembly.

The rear suspension comprises a transverse torsion axle with trailing arms attached to the body via rubber bushings. The axle is attached to the lower ends of the rear shock absorber, which act as struts, containing the mountings for the coil springs. Side-to-side movement of the axle is controlled by a diagonal rod. Some models use a self-levelling system that uses gas and hydraulic pressure acting on the rear struts to maintain the vehicle at the same height regardless of load.

The steering is rack and pinion mounted on the engine compartment bulkhead. The connecting tie rods are centrally attached to the common suspension, which is separately bolted to the steering rack. Some models use a booster, and a steering shock absorber is used on versions with direct-acting steering.
