4 signs of 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 of the car moving
 |
You may hear a grinding or screeching noise. This could be caused by worn or chipped moving parts like the ring gear or pinion gear. Differential bearings or axle shafts can also make similar noises.
2. The car vibrates when moving
 |
There are many reasons why a vehicle vibrates while driving, and a faulty differential is one of them. The semi-shafts usually mesh with the gears in the differential using a spline. When the splines are damaged for some reason, the movement of the semi-shafts will be unstable, leading to vibration.
3. Differential oil leak
 |
The differential is a moving part so it will generate heat due to friction between 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.
