What is a Driveshaft
A driveshaft is one of the most basic parts of an automobile. No matter the age of your vehicle, if it is not a front-wheel drive, it probably has at least one driveshaft.
Driveshaft Basics
The ultimate purpose of the driveshaft is to transmit power from the engine to the wheels. It is part of a system called the drive train. Power goes from the engine to the transmission.
Rear Wheel Drive
In both rear wheel drive and 4-wheel drive vehicles, the driveshaft is connected to the transmission and carries power to the rear differential, where it is transferred to the rear axle to which the wheels are attached.
Four Wheel Drive
In a 4-wheel drive vehicle you have the rear drive shaft and also a transfer case and front driveshaft. Both driveshafts are connected to the transfer case. The transfer case gets its power from the transmission. The front driveshaft connects to the front differential, putting power to the front wheels when needed.
