Symptoms drivers describe
- Rhythmic clicking on full lock, often while manoeuvring
- Clicking that gets faster as you drive faster
- Vibration under acceleration
- Grease visible around the inside of a wheel
Possible causes
- A worn outer CV joint
- A split CV boot letting grease escape and dirt in
- Worn inner joints causing vibration under load
- Worn suspension joints producing a similar knock
- A loose driveshaft nut
What you can do
- Look for grease thrown around the inner wheel rim
- Note which way you have to steer to hear it
- Have it checked promptly if grease has been lost
How we check it in the workshop
We inspect the boots and joints for play and grease loss, and rule out suspension joints and bearings on a road test and lift inspection.
Is it safe to keep driving?
Have it seen to. A split boot rarely improves and a failed joint can leave the car undriveable.
