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).

1994 Explorer Sport 4x4--Clunks when shifting between gears (automatic) and when applying brakes. I've been told it needs bushings and U-Joints. I can't find a mechanic to fix it for me...must be very difficult to repair. I'm a woman--don't know much about this stuff.

Squeeking or clunking noise when hitting irregular spots on pavement. Radius arm bushing[s] were worn as well as one of the bushing mounting brackets. Replacement bushing kit for both sides was installed and one mounting bracket too worn to hold bushing was replaced.
