General information about suspension and steering (Audi A4 B5)

1. Front suspension - independent, with four wishbones (two lower and two upper on each side) and vertical posts (or steering knuckles). The upper and lower arms form a V-shaped structure of unequal length. The shock absorber strut with a coil spring is reinforced between the front lower wishbones and the upper wishbone mounting bracket. The steering knuckles carry the wheel bearings, brake calipers, hub/disc assemblies, to which the upper and lower arms are attached by ball joints. All models are equipped with a front anti-roll bar, which is attached to the subframe via rubber bushings and connected to the front wishbones by vertical rods. The subframe carries the supports of all lower suspension components, as well as the engine and gearbox.

2. The rear suspension consists of a torsion beam with longitudinal arms, coil springs and telescopic shock absorbers. The front ends of the longitudinal arms are reinforced to the bottom of the body through rubber bushings. The rear ends of the arms end in shock absorber struts with coil springs. To reduce body roll, a stabilizer bar is installed.

3. The suspension type code is stamped on the V1N identification plate and on the identification sticker in the spare wheel compartment (Fig. 1.3).



4. The steering column has a flexible joint at the bottom and is attached to the steering shaft with a clamp and bolt.

5. The steering gear is mounted on the body and connected to the steering knuckles by rods with steering ball joints located behind the suspension struts. The steering ball joints have threads to adjust the wheel alignment angles. The power steering has a pump with a belt drive from the crankshaft pulley.
