DESCRIPTION
CAUTION: Suspension components with rubber/urethane bushings should be tightened with the vehicle at
normal ride height. It is important to have the springs supporting the weight of the vehicle when the fas-
teners are torqued. This will maintain vehicle ride comfort and prevent premature bushing wear.
The rear suspension is comprised of :
•
Drive axle
•
Shock absorbers (5)
•
Coil springs (1)
•
Lower suspension arms (4)
•
Upper suspension arm (2)
•
Stabilizer bar (3)
WARNING
WARNING: Suspension components with rubber bushings must be tightened with the vehicle at normal ride
height. It is important to have the springs supporting the weight of the vehicle when the fasteners are
torqued. If springs are not at their normal ride position, vehicle ride comfort will be affected and cause
premature bushing wear.
