Why Does My Car Need a Differential?

If you’re driving a rear-wheel-drive (RWD) vehicle, the differential is the part that allows the two rear axles to operate effectively at two different speeds. Without the differential, you would experience skidding and slipping as the wheels attempt to negotiate a turn.

In a right turn, for example, the wheels on the right are referred to as the inside wheels, and those on the left are the outside. The inside wheels are closer to the turn, so they travel a shorter distance and at a slower speed than the outer. On the other hand, the outside wheels are required to make a wide arc and must travel much faster than the inside. The gears in the differential provide the synchronization to allow the two sides to work together.

The differential provides an important element to your RWD, and it’s important to keep up with its maintenance. If you’re in the local area, feel free to stop by Sheehy Ford Of Gaithersburg. Our knowledgeable service technicians are here to help you with your questions.
