Not known to many people, the differential within your vehicle’s transmission system plays an important role. It’s because of this component that the power generated from the engine and transmission is transferred to the wheels, and the differential allows for greater control of the vehicle. The type of differential can vary depending on the type of vehicle you have as well. Rear-wheel-drive vehicles will have a rear differential, while front-wheel-drive vehicles will have a front differential. Do you drive a four-wheel drive or all-wheel drive vehicle? Well, your car ends up with both!

Because of its importance, the team at Trans Masters Auto Care and Performance believes you must know when the differential is experiencing issues. Although there’s not much you can do, especially if you don’t have technical experience with the component, knowing the signs will allow you to act quickly and visit a professional before the problems worsen. Here are some common differential problems to look out for, and how you can tell if it’s this component instead of a different one within your vehicle:

  • Leaking Oil: To the untrained eye, it can be difficult to tell if oil leaking from your car is coming from the differential or if it’s coming from elsewhere. But you can tell if it is coming from your differential if you pay attention to where the leak is located. if the leak is coming from under one of the axles, that’s a good sign it’s coming from the differential. If you see this, act quickly and have the issue fixed as soon as possible.
  • Noises: Your car can produce a variety of different sounds when something is wrong. The sound you should pay attention to is if you hear a loud whirring noise, as this is what the differential will produce if something’s off. With that said, it can be difficult to determine what’s exactly wrong, so make sure to have yours checked as soon as you can.
