The front suspension consists of MacPherson struts and a single wishbone lower control arm. Strut towers located in the wheel wells locate the upper ends of the MacPherson struts. If the vehicle is equipped with Programmed Ride Control (PRC), the PRC actuator bolts to the top of the strut mounting block which houses a rubber mounted strut bearing. The upper end of the coil spring rides in a heavy rubber spring seat. A forged steering knuckle bolts to the shock absorber. If the vehicle is not equipped with PRC, the struts used are the conventional non-adjustable type and cannot be interchanged with the PRC type. Also, PRC actuators will be absent from the strut mounting block.
The lower ball joint is pressed into the control arm and is attached to the steering knuckle. The wide stance control arms are supported by rubber bushings at each end. Body lean on turns is controlled by a hollow stabilizer bar that connects to both lower control arms.
The front wheels are attached to the front hub and rotor assemblies. The front hub and rotor assemblies are supported by 1-piece roller bearings mounted in the steering knuckle. The wheel bearing is pressed into the steering knuckle. The hub assembly is pressed into the wheel bearing during assembly.
The Programmed Ride Control feature allows for the selection of sport, normal and soft combinations of damping control from the front and rear shock absorbers. The PRC switch, located in the center console, lets the driver select either the manual or both automatic control modes of the PRC suspension.
Selecting SOFT will provide soft damping at all times and under all conditions. Selecting NORM or SPORT will engage the Automatic Adjusting Suspension feature, which provides combinations of hard or very hard damping dependent upon sensor inputs for vehicle speed, acceleration, braking and cornering. This helps to control vehicle roll, pitch and dive and provides improved handling at high speed.
