Noise Over Bumps Due to Radius Arm Bushing Wear on Ford Explorer

The radius arm bushing may wear, causing a clunking or popping noise when driving over bumps. To repair, the bushings need to be replaced. Depending on the severity of the wear, the brackets may also need replacement. Driving with worn bushings will shorten tire life and cause tire cupping (uneven tire wear).
