Cars are complicated. They are a moving body, pivots and joints, and the nice shiny hood just makes a nice disguise for the complexities churning underneath. One of these mysterious parts is called a differential. If you have ever had to get differential repair in Sandy Springs, then here's what was being repaired and why it's important to your vehicle. The Facts A differential's purpose in life is to get the engine power aimed at the vehicle's wheels. The rotational speed of the transmission slows as it gets closer to the wheels, and the differential is that last step in slowing down that rotation speed to what is produced in your wheel movements. It also allows the wheels to spin at different speeds, which is how your vehicle is able to make turns with the outside wheel of the turn rotating more times than the interior wheel. Why You Need It If you didn't have a differential, then your car would either make incredibly slow, strained turns, or it wouldn't even be able to turn at all. Also, here's a little more physics for you: speed is equal to the distance traveled divided by the time it takes to go that distance. The front wheels of a vehicle are always having to travel a little farther than the back wheels are, distance-wise. The wheels that are going a shorter distance, the back wheels, are actually rotating at a slower speed than the front wheels. That sounds crazy, right? It's not! It's science. And the differential allows for that difference in speeds without effecting the vehicle's ability to move forward smoothly. Now when you go in for differential repair in Sandy Springs, GA, you'll know what you're getting into and why your differential is really so important to your vehicle.
