Worn or loose components affect the suspension system's ability to control motion and alignment angles, resulting in a deterioration of vehicle handling, stability and accelerated tire wear. The main components of the suspension system are:
Shocks & Struts
Shocks and struts are common replacement parts as they have an impact on the quality of the ride. For most vehicles, it is recommended that you replace shocks or struts between 40,000 and 50,000 miles.
You may want to consider replacing these parts if you notice signs of wear such as fluid leaks, poor steering response, noise, stiffness or a harsh ride. If your vehicle sways or leans when changing lanes or you notice excessive bounce after hitting a bump, you would benefit from new shocks, struts or a suspension system.
