GM Service Manual Online
For 1990-2009 cars only

All vehicles use a 5-link rear suspension consisting of the following components:

    • Upper and Lower Control Arms
    • Stabilizer Shaft
    • Shock Absorbers
    • Rear Axle Tie Rod
    • Coil Springs
    • Air Springs

The ride control is provided by 2 identical direct dual-action shock absorbers that are angle-mounted between the frame and the brackets, which are attached to the axle tubes.

To compensate for vehicle weight, the coil springs are different for the left and right sides. Do not interchange.

Coil spring or air spring suspensions are available. For more information on air spring components, refer to Air Suspension Description and Operation .
