What is the reason for the noise when the car is turning?

1. The sound of the turn signal returning.

If the turn signal is turned on at the same time as the steering, then the sound may be the sound of the rebound clip of the turn signal automatic return mechanism, which needs to be confirmed by the car owner, if so, then this is a normal situation. Sometimes you will hear more than once, at that time, because of the amplitude of your rotation of the steering wheel, the directional column has three automatic return positions in one circle, and if you turn the steering wheel once, then it will sound three times.

2. Friction between plastic parts.

The steering wheel is usually made of plastic parts, and if the temperature gets colder, the plastic will harden, and there is a natural possibility of friction sound.

3. Abnormal noise coming from the steering wheel.

If the abnormal sound comes from the steering wheel, then the problem is 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, replace the airbag hairspring, because the airbag hairspring is damaged. Be careful to remove the steering wheel gently, or unplug the airbag fuse to avoid the airbag from deploying.

4. The ball joint of the steering tie rod is aging.

If the steering tie rod ball joint is aging, then it will cause the steering wheel to shake and make a sound, which is usually replaced by the steering tie rod ball joint and the four wheel alignment after replacement.

5. Steering machine failure.

If the abnormal noise during steering is very large, then it may be caused by too large gear clearance between the steering machine and the steering machine, and the steering machine needs to be replaced.

6. The plane bearing of the shock absorber makes an abnormal sound.

Just open the front cover to listen to whether the sound comes from the position of the top seat of the shock absorber, so that you can know whether it is the sound of the plane bearing of the shock absorber, the plane bearing of the shock absorber sounds, you can apply some butter on the plane bearing, if it still rings after coating, it can only be replaced.

7. The abnormal sound emitted by the balance bar.

If it is not the sound of the shock absorber, then check whether the balance bar glue is loose or damaged, the balance bar glue is loose and damaged, not only will it sound when playing in the direction, but also make a sound when crossing uneven roads, and the loose balance bar glue can be solved by adding gaskets, and if it is damaged, it can only be replaced.

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.

Hello 1

Abnormal noise in the car: 1. The sound of the rebound card of the turn signal. The direction column will have 3 grid return card positions per circle, and the steering wheel will make three gaggling sounds when it plays a circle, which is normal.

The sound made from the outside of the car: 1. The sound made by the plane bearing of the shock absorber is mostly caused by the lack of oil in the plane shaft of the shock absorber. The inspection method is also very simple, open the hood and listen to the sound** whether it is from the shock absorber.

The car makes a noise when it is steering, which is caused by the failure of the steering wheel parts, and it is best to find professional personnel to test and repair it, and replace the equipment that is not smooth in time, so that it can drive more safely and profitably.

The reason for the sound of the car when turning is that the steering wheel is usually made of plastic parts, and if the temperature gets cold, the plastic will harden, and there is a natural possibility of friction when turning.

A sound that appears when the car turns is a warning that tells us that the turn light has been turned on, which is what it means.

First, if it is a sound in the car.

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

If the steering wheel will have this sound after hitting the steering switch, it is the sound of the rebound clip of the turn signal automatic return mechanism, and this sound is normal. If you hit the steering wheel, there will be a pimple, and the steering wheel will turn around and it will appear three pimple sounds, because the steering column has three automatic return card positions in a circle, so this sound will appear. As soon as you turn off the turn signal, the sound will disappear.

2.The sound of the direction post dust jacket.

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.

3.The sound emitted by the interference of the airbag hairspring.

When playing the direction, the sound is emitted from the steering wheel, most of this problem is 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.

Second, if it is a sound outside the car.

1.The sound of the flat bearing of the shock absorber.

Hit the steering wheel to hear the sound is made from many outside the car, this may be the sound of the plane bearing of the shock absorber is short of oil, you just need to open the front cover to listen to whether the sound is from the position of the shock absorber top seat, so that you know whether it is the sound of the plane bearing of the shock absorber, the plane bearing of the shock absorber sounds, you can apply some butter on the plane bearing, if it is still loud after coating, it can only be replaced.

2.The sound of the glue loosening of the balance bar.

The sound is not emitted from the plane bearing of the shock absorber, it is necessary to check whether the balance bar rubber is loose or damaged, the balance bar rubber is loose and damaged, not only will it sound when playing in the direction, but also make a sound when crossing uneven roads, and the loosening of the balance bar rubber can be solved by adding a gasket, and if it is damaged, it can only be replaced.

Most of the hydraulic booster pumps will have this phenomenon, when playing the steering wheel, the booster oil can not circulate and is blocked, resulting in this squeaky sound, one is the sound of the combination of the switch shell and the steering wheel rubbing, the shell fixing screw is loosened and adjusted; The second is that there is a shrapnel inside the shell of the combination switch.

Solution: 1. Try not to kill the direction for a long time, of course, driving is generally not like this.

2. To kill the direction, try to shorten the time to avoid damage to the booster pump.

Turn the steering wheel to hear the sound is made from outside the car, this may be the sound of the plane bearing of the shock absorber is short of oil, you just need to open the cover to listen to whether the sound is from the position of the top seat of the shock absorber, so that you know whether it is the sound of the plane bearing of the shock absorber, the plane bearing of the shock absorber sounds, you can apply some butter on the plane bearing, if it still rings after coating, it can only be replaced.

Find out first that the sound is coming from **.

It is possible that the rack and pinion inside the steering machine are worn.

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. When I went to the repair shop to detect abnormal noise, only nearly 20% of Sun Nao's cars really had problems. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; 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 because of their own lack of understanding of mechanical knowledge, they mistake the reasonable abnormal noise for the car failure.

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

Second, the identification of car noise is limited, the sound of the car is difficult to measure 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., generally the volume of the celery 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 driving 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.
