Why does the rear axle of trucks have a differential?

First you need to think of some basic geometry: The bigger the circle, the longer the circumference. Thus, when you turn, the car is traveling two arcs or circles. The side on the outside of the circle, that is, the opposite side from the direction you are turning, has to travel farther. So if you drive a car in (part of) a circle, the outside wheels will have longer to travel than the inside wheels. For a wheel that's spinning independently of the others, this doesn't matter, but for a powered wheel it does. If you have two wheels solidly connected to the same axle, they'd fight each other when turning, wearing the tires down, and trying to twist the axle. A differential is a clever sort of gearbox which allows power to be split between the wheels, letting them turn at different speeds when cornering.
