Clunking over bumps? Suspension parts to check

A clunk or knock when you hit bumps points to play in the suspension — most often worn sway-bar links, strut mounts, ball joints, or control-arm bushings. The looseness that makes the noise also affects handling.

Is it safe to drive?

Arrange an inspection for a recurring clunk. If the steering feels loose or the car is hard to control, pull over safely and arrange assistance.

What to tell the repair shop

  • Tell the shop where you heard the clunk and whether it happened over bumps or while turning.
  • Mention any recent curb or pothole impact and any change in how the car steered.
  • Ask the technician to inspect the suspension joints and mounts before replacing parts.
