4 signs to recognize a damaged car differential
(Baonghean.vn) - The differential is an important part in the car's transmission system; it is responsible for dividing torque to each wheel, especially when cornering. Therefore, when a part inside the differential is damaged, it will affect the vehicle's operation... You can refer to the signs below to know if the differential is damaged.
1. The sound when the car is moving
 |
You may hear a grinding or screeching noise. This could be due to worn or chipped moving parts such as the ring gear or the pinion gear. Differential bearings or axle bearings can also cause similar noises.
2. The car vibrates when moving
 |
There are many reasons why a vehicle vibrates while driving, and a damaged differential is one of them. The half shafts usually mesh with the gears in the differential by means of spline meshing. When the splines are damaged for some reason, the movement of the half shaft will be unstable, leading to vibration.
3. Differential oil leak
 |
The differential is a moving part so it will generate heat due to the friction between the gears so lubricating oil is used to limit this. At the end of the gear there will be a seal, oil often leaks in this part because the seal is torn. In addition, oil can also follow the path of the semi-shafts on the wheel side, if the seals at both ends of the semi-shafts are not good.
4. The car is difficult to move when first shifting gears.
