General Description System Description

The front suspension is a combination strut and spring design. The frame has isolation mounts to the body and rubber bushings are used for the lower control arm pivots. The strut is gas charged with the upper end isolated by a rubber mount which contains a bearing in order to allow for wheel turning. The vehicle is equipped with a ride control system which automatically controls the damping rate of the struts based on driving conditions. Refer to Speed Sensing Suspension or Road Sensing Suspension.

The lower end of the steering knuckle pivots on a ball joint riveted to the control arm. The ball joint is fastened to the steering knuckle with a castellated nut and cotter pin.
