If you hear a clunking or knocking noise coming from your wheels, it usually means something in the suspension, steering, or wheel assembly is loose or worn. These sounds may occur when driving over bumps, turning, or accelerating. Because they often indicate a developing fault in a safety-critical component, they should be checked immediately.

What does it mean if clunking or knocking comes from the wheels?

Clunking or knocking from the wheels suggests that a joint, bushing, or bearing is not operating smoothly. As parts wear or loosen, they create extra play and movement, which produces noises when the wheel assembly is under stress.

Common causes of clunking or knocking noises

• Worn CV joints or driveshaft issues
• Loose or worn suspension bushings
• Failing ball joints or control arms
• Damaged or worn wheel bearings
• Loose or damaged sway bar links
• Loose wheel nuts or improperly seated wheels
• Brake components rattling or shifting under load

Why do you need to fix this problem quickly?

Clunking or knocking from the wheels is often a sign that a component may soon fail. If left unrepaired, it can cause loss of steering control, wheel lock-up, or uneven braking, putting you and other road users at risk.

How do you know when to get it checked?

You should book an inspection if:

• The noise happens when turning, braking, or accelerating
• The sound gets louder over time
• The steering feels loose or imprecise
• You notice uneven or rapid tyre wear
• The wheel feels unstable or wobbly

What happens during an assessment?

A mechanic will:

1. Test drive the vehicle to replicate the noise
2. Inspect CV joints, driveshafts, and axles
3. Check suspension bushings, ball joints, and control arms
4. Inspect wheel bearings and hubs for wear or play
5. Check sway bar links and mounts
6. Ensure wheels and brake components are tightened and secure

How much does it cost to fix?

Minor fixes like tightening wheel nuts may be free or very low cost. Suspension or CV joint repairs typically cost $400–$900. Wheel bearing or control arm replacements may range from $500–$1,200+.

Is it unsafe to drive with clunking or knocking from the wheels?

Yes. Clunking or knocking from the wheels indicates worn or loose parts that can fail suddenly. Driving in this condition risks steering or wheel failure. The problem should be diagnosed and repaired immediately.
