Rear

DESCRIPTION
The rear suspension comprises four suspension arms, two shock absorbers, two springs, a stabilizer bar and a lateral arm assembly (Watts link).

OPERATION
- The rear suspension arms limit the forward and rearward movement of the rear axle in relation to the frame. Each rear spring is mounted to an upper seat integral with the frame and a lower seat welded to the rear axle housing. To reduce noise and vibration, a rubber isolator is placed between the coil spring and frame.
- The lateral arm assembly (Watts link) is connected between the rear axle differential housing Watts link pivot and the frame. The lateral arm assembly (Watts link) controls the side to side sway of the axle.
- The rear stabilizer bar and links assembly aids in the control of the suspension travel and restricts body roll.
- The rear shock absorbers provide motion and force damping of the rear suspension during suspension travel, jounce and rebound.
- Two different types of rear springs, air springs or coil springs are used. These procedures show air springs, vehicles equipped with coil springs are similar.

CAUTION: Suspension fasteners are critical parts because they effect performance of vital components and systems and their failure can result in major service expense. They must be replaced with the same part number or an equivalent part if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Specified torque values must be used during reassembly to ensure proper retention of these parts. Orientation of the fasteners is also important on all rear suspension arms. Make sure the fasteners are installed in the same direction as when removed.
