What Are the Symptoms of Insufficient Differential Oil?

[McChristian]

When a car's differential lacks oil, a humming abnormal noise will occur in the rear axle. Below are some related introductions about the differential: 1. When the differential is low on oil, it is essential to promptly visit an auto repair shop or a 4S store to add oil to prevent affecting the normal use of the car; 2. Depending on the principle and type, differentials can be categorized into gear-type differentials, central differentials, anti-slip differentials, LSD differentials, Torsen differentials, etc. When the differential malfunctions, abnormal noises will occur in the rear axle, thereby affecting the normal use of the car; 3. There are many reasons for differential failure, including not only insufficient differential oil but also differential gear wear and improper gear adjustment. If the gears are worn, they cannot match other components during operation, and the friction between parts will cause abnormal noises in the differential. In such cases, the differential gears must be replaced. If the spacing between gears is not properly adjusted, it can also lead to abnormal noises, requiring readjustment.
