Front Suspension









This vehicle uses an independent short and long arm design, for the front suspension. The upper and lower control arms are attached to the steering knuckles using conventional style ball joints. The steering arm of the steering knuckle is rearward of the front wheel centerline. The front steering knuckles are attached to the steering gear using a conventional style ball joint outer tie rod end. The upper control arms are mounted to the frame using two pivot bolts. The pivot bolts go through the isolator bushings for the upper control arms and the control arm brackets on the frame. The through bolts have eccentric (cam) washers that are used for alignment adjustments of the front suspension. The lower control arms are also mounted to the frame using two pivot bolts. The pivot bolts for the lower control arms also go through the isolator bushings for the control arms and the control arm brackets on the frame. The lower control arm pivot bolts though do not have cam washers and are not used to provide alignment adjustment of the front suspension.

The suspension design used on this vehicle locates the front shock absorbers inboard of the frame rails. The shock absorbers are remotely actuated using a rocker arm. The rocker arm is actuated through a push rod which is attached to the lower control arm.

The stabilizer bar used on this vehicle interconnects the front lower control arms by attaching to the rocker arms rather then by being attached directly to the lower control arms. This type of stabilizer bar design and actuation is unique to this vehicle.
