Springs :

Coil springs are the most common type of spring and are, in essence, heavy-duty torsion bars coiled around an axis. Coil springs compress and expand to absorb the motion of the wheels. Coil springs can be located between control arms, frame and control arms and in most strut assemblies.

Most coil springs fail due to constant overloading, excessive up and down movement or just a general breakdown due to metal fatigue. Springs can also corrode and rust, especially in northern and Midwestern states where there is a lot of road salt during the winter.

How do you know if you have a suspension problem? You’ll probably feel it if a spring fails, your ride will become hard and jarring. Failed shocks may result in excessive “bouncing” or up and down movement of your car’s front or back end. It may also become harder to steer, and could feel like your vehicle is pulling to the left or right. Send A Friend recommends you have your suspension system checked every 12,000 miles or 12 months.
