Of all the noises a car makes, a clicking or popping sound from the front wheels during sharp turns is one of the most consistently linked to a single cause. It's rarely anything else, which makes it one of the easier symptoms to diagnose with confidence.
The main cause: a worn CV joint
Constant velocity (CV) joints sit at each end of your front driveshafts and allow power to reach the wheels smoothly, even as the wheel turns and the suspension moves. They're protected by a flexible rubber boot packed with grease. Over time, or after impact damage, that boot can crack or split. Once it does, grease escapes and dirt gets in, and the joint wears rapidly without proper lubrication.
The result is a clicking or popping noise that gets louder and faster the more sharply you turn, because that's when the joint is working at its most extreme angle. It's typically most noticeable during slow manoeuvres like parking or tight corners.
How to tell which side is affected
Find an empty car park, turn the wheel fully to one side, and drive slowly in a circle, then repeat on the other side. If the clicking gets noticeably worse turning one particular direction, that usually points to the CV joint on the opposite front wheel, since that's the one under the most strain during that turn.
What happens if it's ignored
A clicking CV joint doesn't fix itself. If you're not sure the noise is turning-related, check whether it's more of a knock over bumps rather than on turns — that points to suspension rather than the CV joint. Left untreated, the joint continues to wear until it can fail completely, sometimes resulting in a sudden and complete loss of drive to that wheel. In the earlier stages, catching a torn boot before the joint itself is damaged means a much smaller repair.
Is it safe to keep driving?
Book it in soonClicking only on sharp turns, at low speed. Drive gently, avoid full-lock manoeuvres where possible, and get it inspected within the next week or two.
Don't delayClicking that's now happening even when driving straight, or accompanied by vibration or a shudder under acceleration. This suggests advanced wear. Get it looked at promptly.
What it typically costs to fix in the UK
| Likely job | Typical UK cost |
|---|---|
| CV boot replacement only (caught early) | £60 – £140 |
| Full CV joint or driveshaft replacement | £250 – £500 (up to £900 on some vehicles) |

Frequently asked questions
Is it safe to drive with a clicking CV joint?
You can usually drive short distances carefully, avoiding sharp turns, but it is not something to leave indefinitely. A CV joint that has deteriorated enough to click can fail completely, which can mean a sudden loss of drive to that wheel. Get it inspected promptly rather than waiting for it to worsen.
Why does my car only click when turning one way?
CV joints work hardest at extreme angles, which happens more on one side depending on which way you turn. Clicking that's worse turning left usually points to the right CV joint, and vice versa, because that's the side under the most strain during that turn.
How much does it cost to fix a CV joint in the UK?
If caught early with just a torn boot and no internal damage, a boot replacement costs around £60 to £140. Once the joint itself is worn, most garages replace the entire driveshaft assembly, which typically costs £250 to £500, though this can reach £900 on some vehicles.
