A clicking or clunking sound that appears specifically on turns, especially at low speed like pulling out of a junction, is most often a sign of CV joint wear. See clicking when turning for the full breakdown.
Why this one is usually treated as worth booking promptly
Unlike a wheel bearing, which tends to wear gradually and predictably, a CV joint that's failed can, in some cases, fail more abruptly — potentially leaving that wheel without drive. That difference is why clicking on turns is commonly treated with more urgency than a similar-sounding wheel bearing hum, even though both can often be driven on short-term.
What tends to indicate it's progressing
- The click getting louder or more frequent
- Clicking starting to appear on straight-line driving too, not just turns
- Any visible grease around the inner edge of a tyre, which can indicate a torn CV boot
Will it fail an MOT?
A torn CV boot or excessive CV joint play is a checked item and can result in a failure. Check your last recorded advisories free at gov.uk/check-mot-history.
Frequently asked questions
What does a failing CV joint sound like?
Usually a clicking or clunking noise that appears specifically when turning, most noticeable at low speed — different from a hum that's constant regardless of steering, which points more toward a wheel bearing.
Why is CV joint wear treated more urgently than other noises?
Because failure can, in some cases, be more sudden than gradual wear elsewhere in the car — a joint that's very worn can potentially stop transmitting drive to that wheel. This is part of why it's commonly booked in promptly rather than monitored over weeks.
Can I keep driving with a clicking CV joint?
Whether driving on yours short-term is appropriate is something only a mechanic who inspects the joint and boot condition can tell you.
What's a CV boot and why does it matter?
It's the rubber cover protecting the joint's grease and moving parts. A torn boot lets grease out and dirt in, which speeds up wear considerably — visible grease flung around the inner wheel is often the first sign.
