What are the advantages of differential? The differential allows wheels on the same axle to rotate at different speeds . When your vehicle goes around a corner the wheel on the outside has to travel faster than the wheel on the inside. The differential allows this to happen. Two wheel drive vehicles have one axle and four wheel drive vehicles have two.
