Which one is yours? Listen first
- Rhythmic rattle on rough pavement — Sway-bar end links are the classic cheap culprit — small ball joints that wear loose and chatter over washboard surfaces.
- Single deep clunk over big bumps — One solid clunk entering driveways points at control-arm bushings or ball joints — bigger parts, and the ones a shop checks for safety-critical play.
- Clunk when turning too — Noise that follows steering input adds tie rods and strut mounts to the list; a worn strut mount also creaks at parking-lot speeds.
What to expect from the shop
Expect the shop to load and shake each joint on a lift — clunks are found by hand, not by scan. Sway-bar links are the frequent cheap answer; struts, ball joints and control arms the pricier ones and the ones that matter for safety. Ask for the specific worn part and to see the play.
