What causes CV boot failure?
The most common problem with the CV joints is when the protective boot cracks or gets damaged. Once this happens, the grease comes out and moisture and dirt get in, causing the CV joint to wear faster and eventually fail due to lack of lubrication and corrosion.
What happens when CV joint fails?
If a CV joint begins to fail while driving, your car will start to pull to one side as one wheel loses power. When the joint breaks completely its corresponding wheel will no longer turn and although the engine may still run, the car won’t move. If possible, slowly steer your car off the road and then call a tow truck.
Why does the outer boot fail more often than the inner boot?
The outer CV joint boots are more liable to break as they have to endure more movement than the inner ones. CV boots problems are one of the most common causes of MOT failures – a small split can cause the grease, because of the closeness to the brakes, to contaminate the brake pads and discs.
