CAUTION: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure can result in major service expense. New fasteners must be installed with the same part number or an equivalent part if installation is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct 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 they were in when removed.

NOTE: If the Watts link pivot stud or nut is loosened, a new Watts link pivot stud and nut service kit must be installed.

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

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 axle and the spring and another between the 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 vehicle.

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.
