A Constant Velocity (C.V.) joint is an advanced mechanical coupling that transmits rotational power at constant speed while accommodating wide angular movements. These precision components are essential in modern automotive drivetrains, particularly in front-wheel drive and all-wheel drive vehicles where wheels must both propel and steer.
Utilizes precisely machined ball bearings and races to maintain velocity consistency
Packed with high-temperature grease and sealed by a flexible rubber boot
Designed in two configurations:
Outer joints (Rzeppa-style) handle steering angles
Inner joints (tripod or plunging-type) accommodate suspension travel
Clicking sounds during turns (outer joint wear)
Vibration under acceleration (joint imbalance)
Grease leakage from damaged boots
Proper maintenance focuses on regular boot inspections and immediate replacement at first signs of cracking. Modern C.V. joints now feature advanced polymer boots and corrosion-resistant alloys for extended service life in demanding conditions.
