Rear Clunk Over Bumps
How to think through clunking from the rear of the car over rough roads.
Quick answer
Rear clunks often come from worn shocks or struts, sway bar links, loose exhaust parts, control arm bushings, or items moving in the trunk.
Most likely causes
- Worn rear shocks or struts
- Loose sway bar link
- Control arm bushing wear
- Loose exhaust hanger
- Loose spare tire or cargo
Basic driver checks
- Remove loose trunk items.
- Listen for one side versus both sides.
- Notice bouncing after bumps.
- Look for oil on shock bodies if visible.
DIY diagnostic path
- Do not crawl under a car supported only by a jack.
- Check cargo and spare tire before assuming suspension failure.
- Avoid towing heavy loads until inspected.
- Record a short video of the noise if safe.
Common mistakes
- Replacing shocks without checking loose exhaust or cargo
- Ignoring unstable handling
- Assuming every rear clunk is a major failure
What to tell the mechanic
Tell the shop whether the noise is rear left, rear right, or central and whether handling changed.
