Chevrolet Silverado / GMC Sierra. Service manual — part 2292

in rubber insulators that are held by clamps to the frame side rails. The ends of the stabilizer shaft
connect to the lower control arms with link assemblies.

The upper ball joint assembly is integrated into the upper control arm. The assembly attaches to
the steering knuckle with a prevailing torque nut.

The lower ball joint assembly is integrated into the control arm. The assembly attaches to the
steering knuckle with a prevailing torque nut.

The upper and the lower control arms have pressed-in bushings. The bolts pass through the
bushings and join the arms to the frame.

Ball joint assemblies have rubber grease seals. These seals prevent the entry of moisture and dirt.
This prevents damage to the bearing surfaces.

Four-wheel drive models have a front suspension that consists of the following components:

Control arms

Stabilizer shaft

Shock module/Shock absorbers

Coil Springs (1500 series)

Torsion bars (2500, 3500 series)

The upper part of each shock absorber (2500, 3500 series) extends through a frame bracket. Two
insulators and a nut secure the upper part of the shock to the frame. A through bolt secures the
lower part of the shock to the lower control arm.

The upper part of each shock module (1500 series) attaches to the frame by 3 nuts. The lower
part of the shock module attaches to the lower control arm by 2 bolts.

A spring steel stabilizer shaft controls the side roll of the front suspension. This shaft is mounted
in rubber insulators that are held by clamps to the frame side rails. The ends of the stabilizer shaft
connect to the lower control arms with link assemblies.

The front end of the torsion bar attaches to the lower control arm. The rear of the torsion bar
mounts into an adjustable arm at the torsion bar crossmember. This arm adjustment controls the
vehicle trim height.

Both RWD and 4WD models have sealed front wheel bearings. These bearings are pre-adjusted
and need no lubrication.
