Worn control arm bushings or a failing ball joint can produce clunking or knocking over bumps, imprecise steering, and uneven tire wear; if a worn front upper control arm or ball joint is the cause, this assembly replaces both in one part. It is backed by extensive in-house and third-party durability testing. See the "Vehicles it fits" section for the full list of fitting vehicles and engine-specific details.
