Suspension

The purpose of the suspension system is to perform six basic functions:

• Maintain correct vehicle ride height.
• Reduce the effect of shock forces.
• Maintain correct wheel alignment.
• Support vehicle weight.
• Keep the tyres in contact with the road.
• Control the vehicle's direction of travel. 

Signs of Shock Absorbers and Coil Springs being in bad condition are unusual noises over bumps, excessive body lean or sway in turns, or that the front end of the vehicle dives sharply in hard braking. Bad shocks also can affect steering control and cause uneven tire wear.
