The job of a car suspension is to maximize the friction between the tires and the road surface. This provides steering stability with good handling to ensure the comfort of the passengers.

A lot of the suspension system’s work is done by the springs to keep the car’s wheels in firm contact with the road. “Suspension,” when discussing cars, refers to the use of front and rear springs to suspend a vehicle’s “sprung” weight. The used rear suspension assembly may be of the dependent or the independent type.

In the rear suspension assembly of the dependent type a solid axle connects the rear wheels of a car. The suspension is quite simple- based either on a leaf spring or a coil spring. In the former used rear suspension assembly, the leaf springs clamp directly to the drive axle. The ends of the leaf springs attach directly to the frame, and the shock absorber is attached at the clamp that holds the spring to the axle. The same used rear suspension assembly can be achieved with coil springs replacing the leaves. In this case, the spring and shock absorber can be mounted as a single unit or as separate components.

In the used rear suspension assembly of the independent type all of the wheels are mounted and sprung individually. This results in what is known as “four-wheel independent suspension”. Any suspension that can be used on the front of the car can be used on the rear. Of course, in the rear of the car, the steering rack- the assembly that includes the pinion gear wheel and enables the wheels to turn from side to side-is absent.

The used rear suspension assembly also includes shocks and/or struts, and sway bars. Faulty alignment of the rear axle, badly worn shocks and/or springs, and loose or faulty bushings in the used rear suspension assembly control arms will contribute to the tendency to wheel hop.

The sway bar merely ties the left and right suspension together. When one wheel either lifts or drops quickly the bar transfers some of the developed energy to the opposite side. This minimizes rolling or wallowing of the vehicle.

A strut is a structural piece designed to resist pressure in the direction of its length. Most shock absorber struts in used rear suspension assembly are hydraulic units which force fluid through restricting openings in the valves. This restricted flow serves to slow down and control rapid movement in the car springs as they react to road irregularities.
