One of the most important links in the drivetrain of a car is half shaft. Its main job is to transfer power from the differential to the wheels and make them turn so that they can move the car. The half shaft is advanced from a technological perspective; it's commonly made of high-strength steel or aluminum and usually consists of CV joints that are necessary to make flex in the suspension system. These features provide uninterrupted power delivery to practice the wheels even if the move up and down over uneven surfaces. The half shaft is a common component of applications and appears in most modern front-wheel and rear-wheel drive vehicles, though all will be found with four-wheel drive systems where it can come in pairs.
