What Is a CV Boot on a Car?

The CV boot, short for constant velocity boot, is an essential component of a car’s drivetrain system. It is a protective covering that wraps around the CV joint, which connects the drive shaft to the wheels. The CV boot is typically made of rubber or thermoplastic material and is responsible for keeping grease inside the CV joint while protecting it from dirt, debris, and moisture.

The CV joint allows the wheels to turn smoothly and transfer power from the engine to the wheels. Without a functioning CV boot, the CV joint can become damaged, leading to costly repairs and potential breakdowns.
