When we think of common suspension wear parts, struts and shocks come readily to mind. Like filters and brake pads, these components were not designed to last the life of the vehicle and so require periodic replacement. After so many miles their deterioration results in a rough riding vehicle that no longer handles crisply, and new shocks and struts are needed to restore handling performance and ride quality. But the mounts where struts and shocks attach to your vehicle can also wear, fail and require repair.
