Why is the Differential Important?

If you’re operating a rear-wheel-drive (RWD) vehicle, the differential is responsible for the rear wheels’ ability to turn. Each wheel turns at a different speed, and the differential harnesses each with a set of gears to allow them to work together.

When you make a turn, either left or right, the wheels closest to the direction of the turn are referred to as the inside. Those on the other side of the vehicle are called the outside wheels. The outer wheels travel farther and faster to keep up with the number of rotations the inner wheels make. The differential allows the difference in ratio to occur so that your turn is smooth.

If you’ve started hearing a whining noise in the rear of your vehicle, it may be time to have it serviced. Stop by Volvo Cars of New Bern the next time you’re in the local area. One of our technicians will be happy to speak with you and answer any questions.
