Why Does My Car Clunk Over Bumps? Causes and Fixes for Redding Drivers
Stop the Clunk and Regain Control of Your Ride
A clunk over bumps means something in the suspension has worn loose. Finding it early keeps a small repair from turning into a safety problem.
A clunk over bumps: book soon. Loose or wandering steering with it: book now, since a steering part may be failing.
Why does my car clunk over bumps? A suspension part has worn enough to move where it shouldn't. Common causes are worn sway bar links or bushings, shocks or struts and their mounts, ball joints, control arm bushings, and tie rod ends.
Your suspension is made to absorb bumps quietly. A clunk, knock, or rattle over potholes and speed bumps means a part has worn enough to move where it shouldn't. Excess bouncing or the nose diving when you brake are related signs.
Common causes of clunking over bumps
- Worn shocks or struts, or their mounts. Shocks and struts replacement
- Worn sway bar links or bushings. A common, inexpensive cause of clunks.
- Worn ball joints or control arm bushings. These affect steering and need attention. Steering and suspension repair
- Worn tie rod ends. Often come with loose or wandering steering.
- A worn CV axle. Usually clicks when turning rather than clunking over bumps. Axle and CV joint repair
Hearing a clunk?
Book a suspension inspection and we'll find the worn part.
How we find the cause and fix it
- We road test the car to hear the noise for ourselves.
- We lift the car and check every suspension and steering joint for play.
- We send you photos of the worn parts and give you an estimate before any work.
- After suspension work, we check the alignment so your tires wear evenly.

Is it safe to keep driving?
