CV Joint Buying Guide
Last updated: 24 April 2026
CV (Constant Velocity) joints transmit drive from the gearbox to the wheels while allowing for suspension movement and steering angle changes. Clicking on turns is the classic symptom of a worn outer CV joint. At CarParts247 we stock CV joints and complete driveshafts from GKN/Lobro, SKF, and GSP for front-wheel-drive and all-wheel-drive vehicles.
CV joint failure symptoms
Outer CV joints wear from steering angle stress and are the most common to fail. Inner CV joints (plunging joints) handle axial movement and fail less often but cause different symptoms.
- Clicking or popping noise on full lock turns — worn outer CV joint
- Vibration during acceleration — worn inner CV joint or driveshaft
- Grease on the inside of the wheel or wheel arch — split CV boot
- Clunking when shifting from reverse to drive — worn inner joint
- MOT failure for a damaged or missing CV boot
Boot replacement vs complete driveshaft
If the boot has only recently split and the joint is not yet contaminated, a boot replacement can save the joint. If clicking has started, the joint is damaged and needs replacement.
- Split boot caught early: replace the boot, repack with CV grease, and re-clamp
- Clicking on turns: the joint is worn — replace the joint or complete driveshaft
- Complete driveshaft replacement is often more cost-effective than joint-only work
- Always use the correct CV grease specification — wrong grease shortens joint life
- Check the other side — both driveshafts are usually the same age and mileage

Frequently Asked Questions
Can I drive with a clicking CV joint?
Briefly, yes, but the joint will deteriorate quickly. A severely worn CV joint can seize or separate, causing sudden loss of drive. Replace it promptly.
CV joint vs complete driveshaft — which should I replace?
If the joint is worn, replacing the complete driveshaft is often quicker and more cost-effective. The labour saving can outweigh the extra parts cost.
How long does a CV joint last?
CV joints can last the life of the vehicle if the boots remain intact. Once a boot splits and grease leaks out, the joint typically fails within a few thousand miles.
