The direction of the car is heavy while driving, and sometimes it is unstable and swings the steerin

Hello, the clearance of the transmission mechanism in the steering machine is too large. The horizontal and tie rod joints are worn loosely. The mating clearance between the kingpin and the bushing of the steering knuckle is too large. The front wheel hub bearings are loose. Inaccurate front wheel alignment. A little advice, hope!

Summary. Expand your information; Toe-in is too small or anti-toe-toe. 2. The front wheel bearing of the car is loose or the big nut of the horn is loose. 3. The gap between the kingpin of the steering knuckle and the bushing is too large or the horizontal tie rod monk head is loose. 4. The tire rim is deformed.

Dear, glad to answer for you! The unstable steering wheel of the car in driving is that the meshing clearance of the steering gear transmission pair is too large, and the gap between the upper and lower bearings of the steering worm is too large or worn loosely, resulting in the increase of the clearance of the square god and the direction of the disc 2, the wear and tear of the ball joint pin of the longitudinal and transverse tie rods, and the loosening of the fastening nut. 3. The spline of the steering rocker arm is loose with the free stove or the fastening nut is loose.

I've hit a wheel once before.

Expand your information; Toe-in is too small or anti-toe-inverse. 2. The front wheel bearing of the car is loose or the nut is loose due to the hailstorm. 3. The gap between the kingpin and the bushing of the steering knuckle is too large, or the horizontal tie rod and socks are still loose. 4. The tire rim is deformed.

If you have installed a car, it is most likely that the wheel rim is deformed.

If there is an abnormality, it needs to be repaired or replaced in time.

The reasons for the unstable left and right swing of the steering wheel: 1. Tire pressure failure, which needs to be repaired as soon as possible; 2. The dynamic balance data of the four wheels is incorrect, it is recommended to check the dynamic balance of the next four wheels, and if the data is not right, it can be readjusted.

When the vehicle drives to a more bumpy road, many car owners feel that the steering wheel swings left and right, which is difficult to control, so what is the reason for the steering wheel swinging left and right on the bumpy road?

The steering system of the car will shake left and right according to the change of the suspension height of the vehicle, and when it reaches a bumpy road, the cushioning amplitude of the shock absorber will be transmitted to the steering wheel, and the steering wheel of the vehicle is connected to the steering system, so when the road surface is bumpy, not only the body will shake the steering wheel but also swing left and right.

How can I improve the steering wheel swing from side to side?

For the undulating road surface, the left and right swing of the steering wheel is unavoidable, so in the process of driving, the car owner tries his best to ensure the direction of the steering wheel, hold the steering wheel, ensure the direction, and avoid the steering wheel swinging left and right because of the shaking of the body. The driver should not hold his hand on the inside of the steering wheel or hold the steering wheel backwards, so that when the steering wheel is shaking, not only can the steering wheel not only not ensure the direction of the steering wheel, but also may injure the wrist.

Steering wheel instability refers to the phenomenon that the front wheels of the car swing, the steering wheel shakes, and the hand feels numb. When the speed reaches 40 km/h, the steering wheel shakes, the front wheels sway, and it is difficult to control the steering wheel in severe cases.

The reason for the instability of the steering wheel 1. The meshing clearance of the steering gear transmission pair is too large, and the clearance between the upper and lower bearings of the steering worm is too large or worn loose, resulting in an increase in the steering wheel clearance; 2.The ball pins of the longitudinal and transverse tie rods are worn and loose, and the fastening nuts are loose; 3.

The steering rocker spline is loose or the fastening nut is loose; 4.The steering knuckle kingpin and bushing are seriously worn, and the mating clearance increases; 5.The axial clearance of the front wheel hub bearing is too large; 6.

The knuckle arm fastening nut is loose, and the front leaf spring U-bolt is loose. Car steering wheel malfunction sign 1. The steering wheel vibrates violently when the vehicle is moving.

When the vehicle is traveling at speeds above moderate speed, the chassis emits periodic noises. In severe cases, the cab and doors will tremble, and the steering wheel will vibrate strongly until the hands become numb. This is caused by the destruction of the dynamic balance of the directional transmission device and the excessive wear of the transmission shaft, spline shaft and spline sleeve.

2.Heavy and difficult turns. Steering system The rolling bearings and sliding bearings of each part are too tight, the bearing lubrication is poor, the ball head of the steering tie rod and tie rod is too tight or lacks oil, and the steering shaft and shell are bent, resulting in jamming; The front wheel toe is not properly adjusted, the front car or frame is bent, and the deformed tires are not enough, especially the front tire pressure is insufficient.

As long as you walk on uneven roads or small potholes, there will be steering wheel shake and the body will be difficult to control.

There are several aspects to be aware of when a steering wheel shakes occurs.

1. When the car is driving in Peisen, the steering tie rod and the steering tie rod are deformed due to collision, and the ball joints of each part are worn loosely or the tires are worn irregularly, which increases or shrinks the toe;

2. When the car is driving, due to the damage caused by the steering shock absorption, oil leakage or deformation of the front hanging spring limb, which affects the stability;

3. The wheel bearing is loose and the ball joint of the left and right steering joints is seriously worn, so that the front wheel positioning is inaccurate;

4. The ball joint of the transverse thrust rod is loose or the bracket is loose, resulting in unstable driving;

5. The wheels are unbalanced, and the balance lead of the original wheels falls off or becomes a swing in the car under the state of high-speed driving, which causes the steering wheel to shake.

Summary. The steering wheel of the car does not move in the driving, and the direction does deviate, which is generally the deviation of the chassis positioning data, and you can choose to do the four-wheel alignment in this case.

What is the problem of the car not moving the steering wheel while driving, but the direction is deviated?

Hello, I'm helping you sort out the answer to your question, please wait a while The car does not move the steering wheel in driving, and the direction does deviate in this case, which is generally a deviation in the chassis positioning data, and in this case, you can choose to do four-wheel alignment.

What is the reason why the car still deviates when I turn the steering wheel.

One is that the tire is eccentric, and the other is that the chassis positioning data is inaccurate.
