Constant Velocity Joint (CV Joint)
A flexible coupling that transmits torque at variable angles without speed fluctuation.
CV joints are found in front-wheel-drive and independent rear suspension vehicles. They allow power transmission while wheels turn or move vertically. Protected by rubber boots filled with grease, they can fail if the boot tears, allowing dirt and moisture in. Clicking noises during turns signal wear. Replacing CV joints or boots prevents drivetrain failure. Regular inspection ensures smooth operation and safety, particularly for high-mileage vehicles.
