Rear Suspension
Rear SuspensionWARNING: All vehicles are equipped with gas-pressurized shock absorbers which will extend unassisted. Do not apply heat or flame to the shock absorbers during removal or component servicing. Failure to follow these instructions may result in personal injury.
CAUTION: Suspension fasteners are critical parts because they affect performance of vital parts and systems and their failure can result in major service expense. A new part with the same part number must be installed if installation becomes 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.
The vehicle can be equipped with either a vehicle dynamic suspension (using air springs in the rear of the vehicle) or a standard suspension (using coil springs in the rear of the vehicle). Both are an independent-type rear suspension which utilize a stabilizer bar to aid in vehicle stability. The wheel hub and wheel bearing assemblies are sealed units and are serviced as such. The rear suspension has serviceable lower ball joints and wheel knuckle bushings. The rear suspension also incorporates toe links to adjust the rear toe and camber adjustment can be made using camber shims located at the upper arm-to-frame mounts. The rear suspension consists of the following parts:
^ Upper arms
^ Lower arms
^ Shock absorber and spring assemblies
^ Wheel knuckles
^ Wheel bearing and wheel hub assemblies
^ Stabilizer bar
^ Stabilizer bar links
^ Upper trailing arms
^ Lower trailing arms
^ Toe links
