Worn bushings or a bent arm can show up as clunking over bumps, uneven tire wear or vague handling. If the arm is the cause, this one replaces it. Alignment and other worn suspension parts can produce those signs too, so inspect the bushings for cracks or tearing and the arm for bends during a wheel-off tire or brake service.
