1. Control arm rubber sleeve. The control arm rubber sleeve, also known as the triangular swing arm, is fixed at the position of the suspension and the wheel to play a role in stable driving. The car may swing up and down when driving on uneven roads, and the control arm will also move up and down accordingly. , so a rubber sleeve is needed as a buffer, otherwise the car will make abnormal noise or mechanical friction sound. In addition, there will be two problems after the control arm rubber sleeve is aging, it will make abnormal noise when passing the speed bump, very It is possible for the car to deviate
Second, the engine foot pads. This foot pad is also often broken. It supports the engine and plays a buffering role. When the engine is working, there will be a certain vibration. If the engine is directly connected to the frame, the vibration will inevitably be transmitted to the car, making the inside of the car. The comfort becomes worse. With the cushioning of this foot pad, most of the vibration will be filtered out, and the vibration will not be felt in the car. If you feel the vibration in the car is relatively large, especially in the case of idling, it means that The foot pads are broken and cannot absorb shock caused by
Third, the ball cage dust jacket. This is a part on the half shaft, the connection between the half shaft and the gearbox and the wheel bearing is not straight, and sometimes the angle of bending will be very large, so each end of the wheel will have a ball cage sleeve, and the rotation of the ball cage needs to be lubricated Oil lubrication, and the dust jacket of the ball cage is to protect the lubricating oil and prevent external dust from entering the ball cage. There is a dust jacket on each side of the wheel, which may be damaged. If the external sand particles enter the ball cage, it will cause major damage, and the steering will fail in serious cases.
