Rear Suspension

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 with the same part number or an equivalent part must be installed 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 4 suspension arms, 2 Shock absorbers, 2 springs, a stabilizer bar and a Watts link assembly.

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 Watts link assembly is connected between the rear axle differential housing and the frame. The Watts link assembly 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. The rear suspension consists of the following parts:
^ Upper arms
^ Lower arms
^ Lateral arms
^ Watts link pivot
^ Stabilizer bar brackets
^ Stabilizer bar
^ Stabilizer bar bushings
^ Stabilizer bar links
^ Shock absorbers
