What is the Purpose of a Differential?

The differential in a rear-wheel-drive (RWD) vehicle provides the rear wheels with the ability to maneuver at different speeds. In this configuration, the rear wheels are the power that pushes the car forward.

The differential’s mechanical artistry kicks in when you guide your vehicle around a corner. For instance, you are making a right turn. The wheels on the right are going to be considered the inside wheels, and those on the left will be the outside. As the wheels closest to the turn, the inside wheels have the advantage of moving slower and traveling a shorter distance than the outside. The outer wheels must make up the distance of a wide arc by increasing speed to keep up with the inside. The gears inside the differential synchronize that movement between the two sides.

The differential is often overlooked when it comes to maintenance of your car. Changing its oil every 30,000 miles will help keep it in peak performance If you’re in New Athens, IL, stop by our showroom at Weir Chrysler Dodge Jeep Ram.
