The differential we are talking about today is to adjust the speed difference between the left and right wheels, so that the left and right wheels can roll at different speeds (reasonable torque distribution). But what everyone does not know is that the differential is actually a vulnerable product. Many netizens have reported that the differential of their car will make a noticeable buzzing noise.So, how to solve the humming of the differential? Can the abnormal sound of the differential continue to open?
When the differential is buzzing, it means that there is indeed a problem with the differential, but this situation is relatively light, so there will be no problem if you continue to drive. But for safety reasons, we should stop and inspect it immediately, then "prescribe the right medicine" and get repaired by the auto repair shop when necessary. So next, let's talk about the reason for the abnormal noise.
1. Differential oil
It is important to know that the differential oil has a useful life. When it is used for a certain number of kilometers, it must be replaced, otherwise it will cause the lubrication effect of the oil to drop sharply and cause abnormal noise in the differential. In this case, we only need to change the oil.
2. Differential gear
When the gear wear level is more serious, it is definitely difficult to match with other internal parts. Then when the differential is working, it will naturally make a buzzing sound, which can be solved by replacing it with a new gear.If the distance between the gears is not adjusted properly, it will also cause abnormal noise in the differential, which needs to be re-adjusted.
3.Foreign matter on the differential
Of course, it may also be caused by some foreign matter on the differential. At this time, we need to check it carefully. If there is any, just remove it.
