What are CV Joints?

CV Joints or Constant Velocity joints are fitted to all Minis, at both ends of the drive shafts, to transfer torque from the gearbox to the drive wheels.  Outer CV Joints connect the drive shafts to the wheels, whilst the inner CV joints connect the drive shafts to the differential and gearbox.

CV Joint Problems

A CV joint is packed with a special high velocity grease and sealed tight with the rubber boot, that is held in place with two clamps.  The most common problem with CV Joints is when the protective boot splits or is damaged, allowing the grease to escape with dirt and moisture getting in, causing the CV Joint to wear and eventually fail.

Symptoms of a failing CV Joint

Sudden failures of constant velocity joints are rare, but CV Joints do wear out and may fail as a result of loss of lubrication or grease contamination, usually due to a failed boot.

- Clicking noise when turning. 

- Clunk when accelerating or decelerating  

- Humming or growling noise, from the front. 

- A shudder or vibration when accelerating.
