Why should I Replace a Torn CV Boot?
Without axles, cars won’t accelerate. Axles transfer power from the transmission to the wheels. CV joints are a part of the axle that attach to the wheel. They are essential for transferring the torque from the transmission to the drive wheels at a stable speed. In front-wheel drive cars, CV joints transfer the torque to the front wheels of your car. Below is information about CV boots, what happens when they are torn and the signs that this may be happening in your automobile.
What is a CV Joint?
A CV Joint is a joint found on the end of an axle that allows the axle to transmit power at the same speed to the front wheels (or rear in certain applications) regardless of the position of the front wheels. It lets the front wheels turn while still receiving power. Thus, a CV Joint increases performance and is a more efficient alternative to U-Joints that preceded it. Because these joints move in different directions and are built to have very tight tolerances, they need to have enough clean grease inside them to make them rotate. This keeps them from clunking or hopping when your car makes turns. This is where having a fully functioning CV Boot comes into the picture. The boot holds the grease in the joint and protects it from dirt, moisture and heat. It also holds in the grease so that it does not fly out from the centrifugal force created by the rotating axle.
The Consequences of Having a Torn CV Boot
By replacing a torn CV Boot, the joint can be saved keeping the grease in the joint and protecting it from wear. CV Boots should be inspected regularly and replaced immediately if torn. This type of preventative repair can save a lot of money and frustration down the road.
Signs of a Torn CV Joint
- Grease leak: When a CV boot cracks or tears it will usually leak grease onto the inside of the wheel. This leak can eventually be sent into other parts of the chassis or even the underside of the vehicle as the CV axle turns.
- Vibrations from the CV axle: Vibrations may be a result of moisture or debris getting into the CV joint and causing damage. Often, a CV axle that vibrates in this manner must be replaced.
- Clicking noise during turns: When a CV joint has become loose to the point where play has developed, it may cause your car to make clicking noises during turns. A clicking CV joint will often need to be replaced.
CV joints are amazing components that are abused during the life of most cars.
