Description and Operation: General Description

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

All models have a front suspension that consists of the following components:

Upper and lower control arms
Stabilizer shaft
Shock absorbers
Torsion bars (right and left side)

The stabilizer shaft controls the side roll of the vehicle. This shaft is mounted in rubber insulators that are held to the frame with a bracket. The ends of the stabilizer shaft connect to the lower control arms with insulator assemblies.

The upper ball stud assembly is press fit into the upper control arm. The assembly attaches to the steering knuckle with a prevailing torque nut.

The upper ball studs are not replaceable.

The lower ball stud assembly is pressed into the outer end of the lower control arm. A prevailing torque nut joins the steering knuckle to the lower ball stud.

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

All ball studs have grease fittings.

All front wheel bearings are sealed. These bearings are pre-adjusted and need no lubrication.
