Over the years, the road takes a serious toll on your suspension. Potholes, speed bumps, and road hazards all contribute to a sloppy, weak suspension. Change components as they wear to improve safety and ride comfort. If replacing any part of your front or rear suspension, it is best to either do it in pairs (both left and right sides) or examine parts that are prone to failure. This will provide the most service life out of replacement parts and assure they are all performing properly. Skim through the suspension section for your vehicle model to see other parts that may need to be replaced.
