SUSPENSION - FRONT:
Type and Description:  Independent coil spring spherical joint suspension with concentric springs and shock absorbers between upper and lower control arms.

SUSPENSION - REAR:
Type and Description: Independent rear suspension with frame-mounted differential unit, double universal jointed tubular axles, and transverse multi-leaf spring. Differential carrier is mounted to frame by rubber-isolated with hardened and tempered chrome carbon steel leaves bolts solidly to differential carrier and attaches to radius arms with rubber-isolated floating rods. Suspension design permits to function as springing member only. Lateral and longitudinal forces imposed by braking, acceleration, and cornering are absorbed by frame-mounted fixed differential and suspension control arms.
