A constant velocity joint, or CV joint, is a type of universal joint designed to create a smooth transfer of torque from the input and output shafts in order to prohibit fluctuations of speed between the two shaft.
The most common problem with the CV joint is that if the CV boot becomes damaged, it will expose the CV joint to dirt and debris, causing wear
Most manufacturer factory warranties cover the constant velocity joint if it fails due to a manufacturer defect or workmanship. After the manufacture factory warranty expires, an extended car warranty is an available option in order to extend warranty coverage of not only the CV joints, but also many components of the vehicle.
