Differential oil, also referred to as gear oil, is a thicker lubricant that prevents your gears from bumping against each other. In other words, the liquid improves their overall longevity and performance.
Differential oil is a heavy-duty fluid that works under high pressures to ensure that all the gears, bearings, and more are properly lubricated. Without a clean supply of it, your car won’t be working smoothly or safely.
Just like your motor oil, the gear oil can leak, get dirty, or become contaminated over time. If you neglect it, the metal components can end up damaged or worse. To avoid hurting critical systems like your transmissions, you have to be on the lookout for the symptoms of bad gear oil.
Sign #1: Burning Smell
A burning smell is never a good sign, especially when it is coming from your gearbox. The bad odor is an indication that the gearbox is overheating because there’s not enough gear oil or it is too dirty. As a result of the metal-to-metal contact, you may catch the bad smell. Once you realize that it could be your differential fluid, please take your car to a trusted auto repair shop.
Sign #2: Unusual Noises
Bad differential oil tends to cause whirring, whining, or even howling noises. You may even hear metal noises. The strange sounds may worsen whenever your vehicle makes a turn and picks up speed. For this reason, you should take your vehicle to our auto repair shop for inspections.
Sign #3: Vibrations
If you are driving and get random vibrations or shakiness, it may be a symptom of bad gear oil. However, it can be a sign of another mechanical issue. That is why it is best to consult with a professional technician.
