Axle shaft

Axle shaft is on front-wheel drive vehicles, the shafts that connect the transaxle to the driven wheels. Axle shafts are also used on some rear-wheel drive vehicles with independent suspensions to connect the differential assembly to the driven wheels. Axle shafts commonly have a universal joint at each end to accommodate suspension movement. In front-wheel drive applications, constant velocity joints are used that smooth power delivery and allow the wheels to be turned for steering.
