Clunks, Knocks and Squeaks: What Your Car’s Suspension Noises Mean

Speed bumps, potholes, rough industrial-area roads and heavy family SUVs all take a toll on suspension. Suspension parts wear gradually, so the first sign is often a new noise rather than a change you can feel. Here's how to decode the most common suspension noises — and which ones mean you should get the car checked straight away.

Knocking or clunking over bumps

A dull knock or clunk when driving over speed bumps or rough roads is the most common suspension complaint. Usual causes:

• Worn anti-roll bar links or bushes — very common, usually a light knock on uneven roads
• Worn shock absorber or strut mounts
• Worn control arm bushes
• Worn ball joints — these need prompt attention, as a failed ball joint can affect steering control

Clunk or click when turning

A clicking noise when turning sharply, especially in car parks, often points to a worn CV joint on a front-wheel-drive car — frequently caused by a torn CV boot letting dirt in. A clunk when turning the steering at low speed can also come from strut top mounts or steering components.

Squeaks and creaks at low speed

Squeaking over bumps or when the car rocks is often dry or worn rubber bushes — common in hot, dusty conditions. It's usually not urgent, but worn bushes change the suspension geometry and can speed up tyre wear.

Bouncing, floating or nose-diving

If the car keeps bouncing after a bump, feels floaty on the highway or dips heavily under braking, the shock absorbers are likely worn. Worn shocks increase braking distances and reduce grip — a safety issue, not just comfort.

Humming or droning that rises with speed

Strictly speaking this is usually a wheel bearing rather than suspension, but it's often mistaken for it. The noise typically changes when turning left or right as the load shifts across the bearings.

When to stop driving and get it checked

• A loud bang followed by the car pulling or the steering feeling different
• Heavy knocking combined with vague or wandering steering
• A wheel that looks like it's sitting at an odd angle

How we find suspension noises

We road-test the car to reproduce the noise, then inspect it on the lift — checking bushes, links, ball joints, shocks, mounts, CV joints and wheel bearings for play and wear. You get a clear list of what's worn and what's urgent before any work starts. After suspension work, a wheel alignment is often needed, and on cars with driver-assist systems the cameras and radar may also need checking — see when ADAS calibration is required.
