What is the common failure phenomenon of steering bearing?

2,613 Published by Mar 09,2020

Common failure phenomena of steering bearing:

Driving deviation

⑴ Phenomenon: When the car is driving, the steering bearing is in the middle position and the car is automatically moving to one side.

⑵ Reason:

The left and right tires wear differently or have different air pressure. The two front wheel positioning parameters are inconsistent, and the rear wheel positioning parameters are inaccurate (thrust angle formed). The left and right steering tie rods are bent and deformed, and the gap at the hinge is too large. The coil springs of the two front suspensions have unequal spring forces or excessive deformation. Excessive clearance after wheel hub bearings wear. Deformed frame. Deformed front or rear axle. Improper adjustment of the axial machine. Unilateral braking stagnation.

(3) Elimination method: Eliminate them one by one according to the cause of the failure.

Heavy turn

⑴ Phenomenon When I turn the steering bearing left and right, I feel very strenuous.

⑵ Reason:

Front wheel positioning is incorrect. Insufficient tire pressure. The steering gear is deformed and worn, and the ball pin is too tight. There is no oil in the steering gear, the meshing gap of the steering gear meshing pair is too small, the steering bearing is damaged or the preload is too large. Deformation of safety steering column and flange. The front coil spring is broken or the body and frame are deformed. The clearance between the king pin and its bushing is too small or the pressure steering bearing is damaged. The clearance between the horizontal and straight tie rod joints is too small. All moving parts are short of oil.

The impact of automobile steering bearing damage can not be ignored. It affects comfort in the light, tire noise becomes larger, and the vehicle deviates, while heavy will cause suspension damage, make the steering system malfunction and cause traffic accidents.
So how can we determine that the steering bearing of a car may have a problem?

Here are a few points for everyone:
1. Turning the steering wheel in place or at a low speed will make a "squeak ..." sound, and you can feel the steering wheel vibration in severe cases
2. The tire noise becomes significantly louder when driving, and there will be a "humming ..." sound when it is severe.
3. When driving on a bumpy road or passing a speed bump, you will hear a "dong ... dong" sound
4.There is also a deviation of the vehicle, but it is caused by the damage of the steering bearing.
