The CV axle is a drive axle located between the drive wheels. Its role is to deliver consistent power to the wheels as they traverse various types of terrain. The CV axle is attached to the wheels by CV joints.
CV axles were once primarily used on front-wheel drive vehicles. Today, CV axles are common on both front-wheel and rear-wheel drive vehicles.
CV joints connect the transmission to the wheels and are an important part of your vehicle’s drive axles. Each drive axle has two CV joints. The inner CV joint connects the transmission to the axle, and the outer joint connects the axle to the wheels.
Your vehicle’s CV joints connect to the drive axles, which connect the transmission to the wheels. The inner CV joint connects the transmission to the axle, and the outer joint connects the axle to the wheels.
For a driveshaft to be properly balanced, the torque coming from the engine and transmission must be equal to the speed at which the shaft spins. Balancing your driveshaft will ensure smooth driveline operation and help prevent the dangerous and destructive effects of an out-of-balance driveshaft.
Universal joints, often referred to as u-joints, are flexible couplings that serve an important role on your vehicle. One of the primary duties of a u-joint is to transmit the rotational force between the transmission, the driveshaft, and the differentials, which are responsible for turning your vehicle’s drive wheels.
Driveshaft yokes are located on the ends of the driveshaft. In most configurations, one yoke connects to the rear of the vehicle while the other yoke reaches into the transmission. The driveshaft sends power from the transmission and turns the differential, which moves the wheels.
