Here’s What You Need To Know About Car Differentials and How To Fix Them
What Is a Differential?
The transmission takes the power created in the engine and transfers it to the wheels. Imagine if all the wheels spinning at the same right, all of the time – it would be difficult to control your car. The job of the differential is to allow the wheels to spin at different rates, which helps ensure smooth handling and easy speed control. Now, after hearing that, you can imagine why differential problems could be a huge issue right? Of course, you can, but how do you know there’s a problem? That’s coming up next!
What Are The Common Problems?
There are a number of things that could tip you off to a differential problem. While this may not be your issue, you should still see a qualified mechanic if you notice any of the following symptoms of a bad differential on your transmission.
- Transmission Fluid Low – While this may not be reason enough to call your mechanic when coupled with other symptoms it’s a pretty telling sign that something is wrong.
- Whining Noise – This could be an indicator that your differential has problems. It’s one of the most common signs, and it’s characterized by a howl or whine sound that increases in volume as the speed of the vehicle increases. It’s mainly caused by a lack of lubrication.
- Transmission Slips – This symptom is when the vehicle slips in and out of gear without touching the shifter. It’s mostly caused by low oil levels.
- Burning Smell – The burning smell has to do with leaking oil. Without proper lubrication, the components cause the metal to burn oil at a higher temperature, hence the burning smell.
