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. The resulting component has a surface section with a surface section with a surface roughness of /less than 0,025 micrometers.
