What Is a CV Joint?
A CV joint enables the axle to which it is fitted to move through a range of different directions, while still functioning perfectly. If it weren’t for the CV joint, then an axle would detach itself from the transmission or gearbox component to which it is fitted, or would likely fail completely. The CV joint essentially links a road wheel that moves up and down with the component providing the power, which is always stationary and there are CV joints on either end of the axle for full flexibility.
