The primary function of your car’s suspension and steering system is to allow the wheels to move independently of the car, while keeping it “suspended” and stable. Any play or uncontrolled motion in these systems results in a deterioration of handling and accelerated tire wear. Vehicle alignment is closely tied to the condition of the suspension and steering systems.
Worn or loose components affect the suspension system’s ability to control motion and alignment angles, resulting in a deterioration of vehicle handling and stability, and accelerated tire wear.
In automotive suspension, a control arm, also known as an A-arm, is a hinged suspension link between the chassis and the suspension upright or hub that carries the wheel. The inboard (chassis) end of a control arm is attached by a single pivot, usually a rubber bushing.
In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles. They are used on virtually every automobile made and work similarly to the ball-and-socket design of the human hip joint. … A protective encasing prevents dirt from getting into the joint assembly.
Coil or Leaf Springs
A leaf spring is a simple form of spring commonly used for the suspension in wheeled vehicles. A leaf spring takes the form of a slender arc-shaped length of spring steel of rectangular cross-section. In the most common configuration, the center of the arc provides location for the axle, while loops formed at either end provide for attaching to the vehicle chassis.
Coil springs, also called suspensions springs, are made with wide gap coils that compress to absorb impact when tires roll over rough terrain. … In addition to improving ride quality by reducing bounce, coil springs and struts are also a critical component that gives the car its height and keeps it off the ground.
A shock absorber is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy which is then dissipated.
A shock absorber on an automobile does one thing and one thing only, keeps the car from bouncing. Struts are considerably different. Struts are a structural part of the suspension system and are mounted to the chassis of the vehicle on the top, and they come down through.
