The primary function of your car's suspension and steering systems 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.

Suspension System
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. The main components of the suspension system are:

Control Arms
Ball Joints
Springs (Coil or Leaf)
Shock Absorbers
Struts
