What is CV joint?
A CV (constant-velocity) joint is a specialized type of universal joint. Your front wheels move up and down with suspension travel, and must be able to steer while doing so. That requires a pair of articulated joints for each wheel. There’s an inner joint, right next to the transaxle, and a second joint right out by the wheel. They’re connected by a short, round bar of metal, called an axle shaft. These joints are lubricated with a special grease, and are covered by a flexible accordion-pleated boot. The boot keeps the grease inside and dirt outside.
