A clunk over bumps, loose or wandering steering, or uneven front tire wear can mean a worn ball joint or arm bushing, but several suspension parts share these symptoms, so find the source before replacing anything. With the engine off, look at the ball joint boot and the arm for tears, grease leaks or cracks.
