If your vehicle is rear-wheel drive (RWD), then it has a rear differential. RWD means that the two rear wheels are pushing your car forward. They move at different speeds, though, so a differential is designed to synchronize their movements.

When you turn a corner, for instance, force and direction of the turn require different wheel motion. If you’re turning left, then the left wheels will be the inside wheels. They have a shorter distance to travel to make the turn than the outside wheels. They also move slower. The wheels on the right, or the outside, in this case, need to make a wide arc at a greater rate of speed to keep up with the inside. The gears inside the differential allow that to happen.

Maintenance, such as oil changes every 30,000 miles, is an important aspect of keeping your car’s differential running well. Stop by Mtn. View Ford Lincoln the next time you’re in Chattanooga, TN. Our knowledgeable technicians are here to help you with your questions.
