Episode 69 - What is the Axle and Differential?

The engine makes power. That power is sent from the engine to the transmission. Then the power comes out of the transmission and goes to a transfer case that sends the power to the front or the back of the vehicle through the driveshafts to the axles. Inside the axles are another set of gears called a differential, that sends the power to the tires.
