Suspension bushings are the link between your vehicle and it’s springs, struts and shock absorbers. Suspension bushings provide the movement and/or mounting points in your vehicle’s suspension system. Hence these suspension components can influence both the ride quality, steering feel, as well as the grip of the tires, performance of the brakes, and stability of the shock absorbers. Should these suspension components be worn, an unpredictable and more to the point unsafe motor vehicle can be the result.
