In some of our earlier articles we covered how important transmission fluid is. However, your car has another fluid that serves an important purpose, and it isn’t motor oil.
What are the Symptoms of Low Differential Fluid?
What are the symptoms of low differential fluid? First off, what noises is your car making? There are different causes of differential noise, as this excerpt from eHow.com shows:
“Rear differential noise is often caused by friction. While the sound can be similar to tire noise and isn’t always noticeable, leaving your rear differential untreated can lead to hefty charges from a mechanic. The differential distributes the torque in the crankshaft to the vehicle’s wheels, essentially transferring the engine power to the wheels. This makes tire rotation at various speeds possible, which is needed when turning. When your rear differential gives out, your entire vehicle is inoperable.”

There are a few types of differential noise, but they can be broken down into humming, noise while turning, growling, and vibration.
Types of Differential Noises
Humming is the lowest end of the problem scale. If your differential fluid is too low, your car won’t operate smoothly and humming is a key indicator of this. If you ignore the humming, then it becomes growling which means the gears are grinding even worse than they were when the problem first started. The problem gets worse as you turn, and if you let it go too long, then you’re going to get vibration, which means you will likely have a dangerously low fluid level, and a potentially expensive differential repair.
So remember, problems should always be faced and dealt with as quickly as you can, particularly when your car is concerned. So if you need differential repair, take it to a shop that specializes both in transmission and differential repair.
