The bearing of the car steering gear is the core supporting component of the steering system. Common faults can be divided into three categories: abnormal operating feel, abnormal driving noise, and abnormal vehicle stability. The specific manifestations are as follows:
🎮 Steering control fault
Heavy steering: Bearing wear and jamming cause increased rotational resistance, making the steering wheel difficult to turn, and even resulting in a difference in feel between heavy and light on one side.
Difficulty in returning the steering wheel: The bearing raceway is worn and stuck, and the steering wheel cannot smoothly and automatically return to its original position after turning, resulting in a significant increase in free travel.
.Oversteering/understeer: Loose bearings can cause excessive looseness in the steering system, resulting in decreased precision of steering operations and a tendency for delayed steering response.
.🔊 Abnormal noise type fault
Abnormal noise on bumpy roads: When the vehicle is driving on bumpy roads, the steering gear makes a "clanging" metal impact sound, which is caused by loose bearings and loose components colliding.
Abnormal noise of steering friction: When turning in place or at low speed, a sharp friction sound of "squeak, squeak" is emitted, which is mostly caused by dry friction of the bearing raceway after lubrication failure.
.Continuous running noise: During normal driving of the vehicle, there is a continuous low-frequency sound of "buzzing... buzzing" coming from the steering part, accompanied by slight shaking of the steering wheel.
.🚗 Vehicle stability fault
High speed vehicle shaking: After the vehicle starts running, the wheel shaking intensifies, the steering wheel shakes frequently, and the overall driving stability of the vehicle significantly decreases. Inaccurate wheel alignment: After severe wear and cracking of the bearings, it will directly damage the original steering geometry parameters, causing abnormal tire eccentric wear, and in severe cases, there may be signs of oil leakage in the steering gear.
Automatic steering deviation: Bearing failure destroys the stable structure of the steering system, causing the vehicle to automatically deviate to one side during driving. The steering wheel must be continuously corrected to maintain straight driving.
