What are the causes of a car s steering wheel being wrong?

You can do a four-wheel alignment.

When the vehicle is used for a long time, the user finds that the steering wheel is heavy, shivering, misaligned, not homecoming, or the tires are worn unilaterally, corrugated wear, block wear, eccentric wear and other abnormal wear, as well as when driving, the car feels floating, bumpy, swaying and other phenomena, it should be considered to check the wheel positioning value to see if there is too much deviation and repair it in time.

The left and right sides of the four-wheel alignment are:

1.Increase driving safety.

2.Reduced tire wear.

3.Keep the steering wheel straight when driving straight, and keep driving in a straight line.

4.The steering wheel automatically resets after steering.

5.Increases the sense of driving control.

6.Reduced combustion consumption.

7.Reduces wear and tear on suspension components.

The vehicle has a steering wheel malalignment after a period of use, which is related to tire pressure, tire wear, chassis parts wear, and four-wheel alignment. If the tread pattern of the two front tires is not worn consistently, it will also cause the vehicle to deviate. If there is no problem with the tires, it is recommended to go to the 4S shop to check the use of the chassis parts, the value of the four-wheel alignment changes will also lead to the problem of improper steering wheel after a period of use, and it is also possible that the cross tie rod is offset to one side and causes the steering wheel to be wrong.

The solution to the improper steering wheel: do four-wheel alignment: the installation between the steering wheels, steering knuckles and the front axle of the car has a certain relative position, and this installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment.

Front wheel alignment includes kingpin casting, kingpin casting, front wheel camber, and front wheel toe, which is for the two steering front wheels. For the two rear wheels, there is also a relative position installed between the rear axle, called the rear wheel alignment, and the rear wheel alignment includes wheel camber and toe-in one by one rear wheels, so that the front wheel alignment and the rear wheel alignment are called four-wheel alignment in total. Retrofitting lead blocks:

On the edge of the wheel hub, there are one or more small lead blocks of different sizes, which play a very important role in the stability of the car at high speed. Wheel dynamic balance: The wheel of a car is composed of tires and hubs as a whole, but due to manufacturing reasons, the mass distribution of all parts of this whole cannot be very uniform.

When the wheels rotate at high speed, a dynamic imbalance will be formed, resulting in the phenomenon of wheel shaking and steering wheel vibration during driving. In order to avoid this phenomenon or eliminate this phenomenon, it is necessary to correct the balance of each edge part of the wheel by increasing the counterweight, and this correction process is commonly called dynamic balance. If you can't solve it yourself, you can go to the 4S shop to find a professional maintenance personnel to adjust.

Adjust. Knock the steering wheel of the vehicle to the right, revealing the rear of the left front wheel. Loosen the fastening nut with a wrench, rotate the left tie rod clockwise, and screw the left tie rod to shorten.

Then repeat the previous steps and knock the steering wheel to the left, revealing the back of the right front wheel. Rotate the right lever counterclockwise, and the right lever is elongated.

If the left lever is rotated in one week, then the right lever must also be rotated out for one week, and the amount of adjustment on both sides must be the same. Adjustment of the steering tie rod, if the steering wheel is in front, if the steering wheel is to the left, the left wheel will extend the tie rod outward, and the right wheel will be shortened inward, if the steering wheel is to the right, it will be the opposite.

The situation of improper deviation of the steering wheel is generally related to tire pressure, tire wear, chassis component wear, and four-wheel alignment. You can measure the tire pressure first, and when the tire pressure on both sides is not consistent, the vehicle will drive to the side with low air pressure. If there is no problem with the tires, check the use of the chassis parts, and the change in the value of the wheel alignment will also lead to the problem of improper steering wheel after a period of use, and it is also possible that the tie rod is offset to one side and causes the steering wheel to be misaligned.

Most of them are caused by the deformation of the relevant parts of the vehicle suspension system or poor working performance. On the one hand, it has a certain relationship with the working performance of the shock absorber and the shock absorber spring, the deformation of the shock absorber and the reduction of the elasticity of the shock absorber spring will cause the change of the body height, and there is also a possibility that the deformation of the balance bar and its small tie rod will also cause the phenomenon that one side of the body is high and one side is low.

It is normal for the steering wheel to deviate from the left and right five degrees, and if the deviation is large, you need to do four wheels. The reasons for the deviation of the steering wheel, first, the car has been hit, second, the front wheel often knocks on the road, and third, the direction is too fierce Similar problems: beginners feel that the forklift always does not grasp the steering wheel well when turning, and the turning is too large The steering wheel is always inaccurate, and I don't know where the wheels of the car will press.

The steering wheel is not correct and the direction of driving is not exactly two different nature of the problem, the direction of driving is not correct, the old deviation, serious must be corrected, and the steering wheel is not correct and reloaded is not improved, it will be used, it is a rotatable disc, but the visual experience is not happy, does not affect the driving.

If there is no problem with the tires, it is recommended to go to the 4S shop to check the use of the chassis parts, the value of the four-wheel alignment changes will also lead to the problem of improper steering wheel after a period of use, and it is also possible that the cross tie rod is offset to one side and causes the steering wheel to be wrong. If you feel uneasy, you can drive the car to a 4S shop or repair shop for inspection to rule out abnormal noise.

Therefore, it is advisable to turn the key door to the second gear position (or switch it on and off several times) before starting the engine each time, and the petrol pump will automatically run for a few seconds in order to establish a certain fuel pressure. Waiting for the petrol pump to run before starting the engine will improve.

This is a typical four-wheel alignment problem, just go to a tire shop to re-adjust the four-wheel alignment value, which is very convenient and not a big problem. Such as satisfied.

The impact of the improper steering wheel of the car is as follows: 1. The improper steering wheel will cause the rack of the steering wheel to accelerate aging or deformation, resulting in eccentric wear of the tire, and will also cause the vehicle to deviate, resulting in the aging of the shock-absorbing rubber in the suspension system, which will affect driving safety. 2. The impact of the car steering wheel on the tire, when the steering wheel is not right, due to the existence of the kingpin inclination angle and the camber design of the passenger car tire, the tire is not completely tread on the ground, but the shoulder and part of the tread are stressed.

3. The steering wheel is not correct and there is damage to the steering mechanism. If the steering wheel is not correct when parking, the wheels will pull the steering lever and cannot return, and the gear of the steering wheel and the rack of the steering lever are also in a state of stress.
