Scratching your head? Don't worry, if you don't know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Plainfield, Illinois, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. Some Plainfield vehicles might even have two or three.
Not surprisingly, a differential's job is to compensate for differences; specifically, they're the differences in wheel speed when turning. For instance, imagine taking a corner near your Plainfield, Illinois, home. Your inside wheel has a shorter distance to travel than the outside wheel as you turn the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.
The differential allows the wheels to turn at different speeds while still providing power to your vehicle. Without a differential, Plainfield residents' tires would scrub and hop along the pavement during turns like the early cars.
Ever noticed the big bulge in the middle of the rear axle on trucks? That's the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. A front-wheel drive vehicle's differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.
It can seem a little complex to some Plainfield drivers - but you can see that all of the engine's power is routed through your differentials. They're strong enough to handle the work, but- we've said it before - they need to be properly lubricated in order to stay strong. So from time to time, you need to schedule a differential service in Plainfield at Tuffy Tire & Auto Service Plainfield. The used fluid is drained and replaced with clean fluid. Some advise certain differentials to have special additives installed.
