What Your Differential Does

When it comes to modern pieces of machinery, most of us like to leave things up to the experts. With your car, however, it can prove prudent to educate yourself about it a little bit at a time. This can help you spot problems early on, and also give you an idea of if you’ve gotten jilted by a mechanic. To help you with this, we’ve put together a quick overview of one of your car’s parts: the differential.

What it does:

Your differential plays an important role. When you turn in your vehicle, the inner wheels need to turn at a different rate than the outer ones. Otherwise, friction wears them down and you lose some control over your vehicle. Your differential makes this happen. Without it, you’d end up spending a lot of money on new tires.
