If you hear a clunking noise when driving over bumps, it usually means part of your suspension or steering system is worn or loose. This type of noise often comes from components that absorb shocks and keep your car stable. Since these parts are critical for safe handling, the issue should be inspected promptly.

What does it mean if there’s a clunking noise over bumps?

A clunking noise over bumps means that parts of the suspension or steering system are moving excessively or hitting against each other. Worn joints, bushings, or mounts are the most common culprits, but shocks and struts can also be responsible.

Common causes of clunking over bumps

• Worn or damaged shock absorbers or struts
• Loose or broken suspension bushings
• Worn ball joints or control arm joints
• Loose sway bar links or bushings
• Damaged strut mounts or top bearings
• Loose exhaust components hitting the chassis

Why do you need to fix this problem quickly?

Clunking noises usually mean suspension components are worn and may soon fail. If ignored, this can lead to unsafe handling, poor braking stability, and further damage to tyres or other suspension parts.

How do you know when to get it checked?

You should book an inspection if:

• The clunk happens every time you hit a bump
• You notice vibrations or instability at higher speeds
• The steering feels loose or less responsive
• There is uneven or rapid tyre wear
• The noise is getting louder over time

What happens during an assessment?

A mechanic will:

1. Test drive the car to replicate the clunking noise
2. Inspect shocks, struts, and springs for leaks or damage
3. Check suspension bushings, ball joints, and control arms
4. Inspect sway bar links and mounts
5. Check strut mounts and bearings
6. Ensure exhaust and underbody components are secure

How much does it cost to fix?

Minor fixes like replacing sway bar links or bushings may cost $150–$400. Shock absorber, strut, or ball joint replacement typically costs $500–$1,200+ depending on the vehicle and number of components replaced.

Is it unsafe to drive with a clunking noise over bumps?

Yes. Clunking noises from the suspension or steering mean worn or loose parts, which can affect stability and control. The issue should be inspected and repaired as soon as possible to ensure safe driving.
