At first blush, your semi truck driveline is just a couple of tubes, yokes and u-joints, so it seems to be not very complicated. However, without the driveline your truck will not move. It connects the transmission to the axles, delivering torque to the latter ones, so they can rotate the wheels. Both driveline and axles are designed to last for a very long time and can even last the lifetime of the vehicle. Although, just like any other parts they are prone to wear and tear, so breakdowns are possible. If so, on TRUCKiD you'll find all necessary replacement or aftermarket driveline and axle parts for your truck.
