Abstract
A method of manufacturing a vehicle suspension component, such as a helical coil spring, includes the step of rotating a first impeller to project ceramic peening media in a first direction toward the vehicle suspension component to peen a surface section of the vehicle suspension component. In one example, the vehicle suspension component is peened with metal peening media before peening with the ceramic peening media.
