DESCRIPTION AND OPERATION

GENERAL DESCRIPTION

These vehicles use a leaf spring and a solid rear axle suspension system.

The rear axle assembly is attached to multi-leaf springs with U-bolts. The front ends of the springs
are attached to the frame at the front hangers with bolts and are isolated utilizing rubber bushings.
The rear ends of the springs are attached to the frame with bolts at the shackles. The shackles also
utilize rubber bushings for isolation. Shackles allow the springs to change position while the
vehicle is in motion.

Two direct double-acting shock absorbers provide ride control. The shock absorbers are angle-
mounted between the frame. The shock absorbers are attached to the anchor plate.

The rear spring steel stabilizing shaft helps minimize body roll and sway during cornering. The
rear stabilizer shaft is connected to the rear axle and the frame with the following components:

The rubber insulators

The clamps

The link assemblies
