Is the Differential Necessary to Drive?

The first time you tried to make a turn in your vehicle without a differential, you would definitely notice why you need it. The rotation of each wheel is designed to travel at different speeds. The differential provides the wheels’ difference in turning ratio and speed through its gear movements.

The wheels that are closest to the corner when you make a turn are called the inside wheels. They have a short distance to travel to make it around. On the opposite side of the vehicle, the outside wheels, need to travel at a higher rate of speed, and they need to make a wider arc to keep up with the inside. The rear differential makes that happen.

The differential in a rear-wheel-drive (RWD) vehicle is in the back connecting the two rear wheels. It requires an oil change approximately every 30,000. If you’ve been hearing a whining noise, it may be time to have it checked. Stop in to our service center at Bryan Chrysler Dodge Jeep Dodge in Bryan, TX. We’ll be happy to help.
