How to deal with the squeak of the car s steering wheel when turning

In medium-speed driving, especially on uneven road surfaces, there is a click sound or other periodic abnormal noises in a dozen directions, and the steering wheel vibrates abnormally, which sometimes leads to numbness in the hands, at this time it is necessary to check the vehicle in detail to see if the dynamic balance of the direction transmission device, whether the transmission shaft and its spline shaft and spline sleeve are worn, and whether the zero parts are tightened.

It is also possible that the airbag hairspring is faulty, if you find that the sound is emitted from the steering wheel, this problem is mostly caused by the interference of the airbag hairspring in the steering wheel, remove the steering wheel airbag hairspring and apply some butter to see if it still sounds, if it still rings, replace the airbag hairspring, because the airbag hairspring is damaged.

It is also possible that the plane bearing of the shock absorber is short of oil, and when playing the steering wheel, if it is found that the abnormal sound is coming from outside the car, it may be the sound of the plane bearing of the shock absorber due to the lack of oil. Just open the hood and listen to see if the sound is coming from the top seat of the shock absorber, so that you know if it is the sound from the flat bearing of the shock absorber.

As soon as you move the steering wheel, there is a squeaky sound.

First of all, are you driving the steering wheel too hard? Don't kill the steering wheel, leave a little leeway, if you hit it too hard, it will cause damage to the power assist system and make a noise.

Second, check whether the vehicle's booster pump is short of oil, if there is a shortage of oil, add booster oil to solve it.

Third, if it is not caused by the above two reasons, then it is necessary to consider that the power assist system is faulty, you should go to a professional auto repair shop, and systematically check the power pump and steering machine.

First of all, it is necessary to distinguish between normal and abnormal sounds. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Models equipped with turbocharged engines are different; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.

There are many reasons for abnormal sound in the direction, such as the sound of the plane bearing, the sound of the steering cross shaft, the sound of the direction machine, etc., the most common is the sound of the plane bearing, which needs to be checked by the master in the auto repair shop.

1. The cause of the abnormal sound of the steering machine.

1. The steering string is not lubricated and has high friction;

2. Check that the steering power assist oil is less;

3. Check that there is a problem with the universal joint;

4. The chassis suspension balance rod lifting lug sleeve is aging and hardening;

5. The plane bearing is broken;

Second, for the load of the steering machine.

1. From the perspective of the principle of the steering machine, many cars now realize vacuum assistance, but that only reduces the driver's control intensity, and the force of the steering machine itself has not changed. Therefore, the effective way to reduce the wear and tear of the steering machine is to reduce the load on the working of the steering machine.

2. Aging, causing potential safety hazards: car lovers should develop the habit of turning the wheels and then playing the direction, reduce the friction resistance between the tire and the ground, reduce the excessive load of the steering machine and the excessive wear of the direction linkage system, resulting in abnormal noise when playing the direction.

3. Long-term in-situ direction: It not only causes a lot of load to the steering machine, but also aggravates the wear and tear of the tire surface and reduces the service life of the tire.

4. The way to change this habit is: when the wheel rotates slightly, it quickly dials the direction to achieve the purpose of completing the control.

3. The correct way to play the steering wheel.

1. Avoid turning the steering wheel on the spot, try to play the direction after the vehicle moves, and the direction on the spot can only be used occasionally when the car is lowered in a special environment.

2. When the vehicle is stopped, the steering wheel should be returned to the center position to avoid the suspension system and tires from bearing the load.

3. When you need to turn around, try to avoid the steering wheel hitting the dead center.

Check that the airbag hairspring is dry under the plane, so it is necessary to apply a layer of lubricating oil to lubricate it, and try it back and forth with butter to check whether the tie rod ball head of the steering machine is worn.

Steering tie rod ball joint aging: If the steering tie rod ball joint is aging, then it will cause the car steering wheel to shake and sound, this situation is usually to replace the steering tie rod ball joint, and after the replacement of the wheel alignment.

This abnormal noise is caused by a disturbed balance of the directional transmission inside, or excessive wear of the transmission shaft and spline shaft. In medium-speed driving, especially on uneven roads, there will be sounds or other periodic abnormal noises in a dozen directions. If the steering wheel vibrates abnormally, it is necessary to inspect the vehicle in detail to see if the dynamic balance of the steering gear, whether the transmission shaft and its spline shaft and spline sleeve are worn, and whether the zero parts are tightened.

1. The ball joint of the steering tie rod is aging and has an open space. Replace the steering tie rod ball joint and do four-wheel alignment.

2. Oil leakage from the dust jacket of the steering machine. Replace the dust jacket or re-butter it.

3. Steering machine failure. It may be caused by the gear clearance of the steering machine is too large, and the steering machine needs to be replaced.

4. If the tightness of the booster belt is improper or aging, the tightness of the belt needs to be adjusted or replaced.

Hello, I am Changan Ounuo car, there is an abnormal sound in the direction of the car when it starts, and there is no abnormal sound in the same place, what is going on.

It is recommended that you check it out.

1. This situation generally appears in the model of mechanical hydraulic power steering, which is a very common way of steering power in the past, referred to as HPS in English, with mature and reliable technology and low cost. This type of steering power assist converts a part of the engine's power output into hydraulic pump pressure, which exerts auxiliary force on the steering system to steer the tires. When the steering wheel is not turned, the pressure in the chambers on both sides of the piston is the same and it is in equilibrium.

When the steering wheel rotates, the mechanical control valve connected to the steering column will be opened or closed accordingly, one side of the oil will no longer pass through the hydraulic cylinder and directly flow back to the oil storage tank, the other side of the oil continues to be injected into the hydraulic cylinder, the pressure difference between the two sides of the piston will be pushed under the action of the hydraulic force, and then produce auxiliary force, at this time we will feel that the steering wheel is not so laborious.

2. The steering pump drives the belt to slip. The steering pump is driven by a belt, and if the friction between the belt and the pulley is too small, the belt will slip on the pulley, and there will be a squeaky sound at this time. It may be caused by loose belt adjustment, excessive wear of the grooves of the pulley, or the new belt does not fit well with the old pulley.

A simple way to tell is to pour a little water on the belt when there is a noise, if the noise goes away, it means that the belt is slipping. At this time, first adjust the tension of the belt, if there is still a sound after adjustment, you can use it for a period of time to make the belt and the pulley fully match and then see if it is still ringing, if it is still ringing, you have to replace the pulley.

What to do if the steering wheel of the car is abnormal.

1. The sound of rebounding the clip after the turn signal.

2. The sound of the dust jacket of the direction column.

Whether you are in place or driving as long as you hit the steering wheel, you will hear the sound coming from under the steering wheel, you should check the steering post dust jacket, once the steering post dust jacket lacks lubrication, it will produce a dry friction sound, you just need to apply some butter in the dust jacket This sound will disappear.

When the car turns the steering wheel and produces abnormal noise, it may be the abnormal sound of the steering column under the steering wheel, or it may be the abnormal noise of the suspension system.

When buying a mat, be sure to buy a special mat for a special car, so as to avoid interference between the mat and the steering column. If you usually wash your car or use your car in some wet areas, then the steering pillar is prone to rust, and turning the steering wheel after the steering pillar is rusty may produce abnormal noise.

There is some debris near the direction column, which may also cause the direction column to produce abnormal noise.

If there is a problem with the front suspension of the car, then there will be an abnormal noise when the steering wheel is turned. When you open the hood, you can see the top of the two towers that hold the front shock absorbers, and inside this tower there are flat bearings, if the flat bearings are damaged, then there will be a strange sound when the steering wheel is turned.

The front suspension has some bushings, the bushings are rubber products, and the bushings will age after a long time, so the suspension's spacing will become larger, so that there will be abnormal noises when turning the steering wheel.

Usually, before parking and turning off the engine, be sure to turn the steering wheel back to the center. Don't beat the steering wheel to death while driving, you can get it back to the right a little bit after the killing. Do not drive your car on the curb while driving, as this will increase the burden on the suspension system.

Do not splash water on the steering pillar when washing the car, and after cleaning the mat, you should dry the mat completely before putting it back in the car.

The causes of abnormal noises when the steering wheel rotates are friction between plastic parts and abnormal noises coming from the steering wheel. The following is a detailed introduction to the abnormal noise when the steering wheel is turned:

Friction between plastic parts:

Because the steering wheel is usually made of plastic parts, if the temperature becomes colder, the plastic parts will become stiff and cause a friction sound.

Strange noises coming from the steering wheel:

If the abnormal sound comes from the steering wheel, it is very likely to be caused by the airbag hairspring in the steering wheel, remove the steering wheel airbag hairspring and apply some butter to see if it still sounds, if it still rings, you need to replace the airbag hairspring, because the airbag hairspring has been damaged. Be careful to remove the steering wheel gently, or unplug the airbag fuse to avoid the airbag from deploying.

It may be that the balance of the directional transmission inside has been broken, or there has been excessive wear on the transmission shaft and spline shaft.

In medium-speed driving, especially on uneven roads, there are a dozen directions"Click"Sound or other periodic abnormal noise, abnormal vibration of the steering wheel, sometimes lead to hand numbness, then it is necessary to check the vehicle in detail to see the dynamic balance of the steering gear, whether the transmission shaft and its spline shaft and spline sleeve are worn, and whether the zero parts are tightened.

The car squeaks when the steering wheel squeaks? Don't blindly go to the 4S store, the problem may appear here.

1. The abnormal sound of hitting the direction in situ should be the sound of the spring steel plate rubbing against the steering wheel by the speaker line under the steering wheel, usually the sound comes from the car, and it is the sound of rustling metal rubbing. The solution is to apply some lubricating oil to the friction between the spring steel plate and the steering wheel.

2. If it is an abnormal sound in the direction of driving, usually the sound comes from the front suspension outside the car. If it is a sharp squeak, then it should be the grinding sound caused by the front wheel toe being too large or too small, and the front wheel not turning parallel to the direction when hitting the direction. If it's a rattling sound, it's the abnormal sound of your car's half-shaft cage being worn out excessively, and it's time to replace it.

Usually the left wheel is a damage to the right cage.

3. It is recommended to check it lightly or use the elimination method to find out whether it is caused by the following three conditions:

A When the tires are wheeled in place, the friction between the tires and the ground will produce abnormal noise.

b.The steering ball joint is damaged or loose.

c The assistant system will have a sound when the hydraulic pressure works.
