What s the reason for the abnormal sound of the rotation in the direction of the natural sound?

Hello, if the sound is coming from under the car, you may need to check the steering machine, the steering knuckle, and if it is coming from the engine compartment, you may need to check the shock absorbers.

Flat bearings and bracket ball joints.

1. The sound of the friction between the direction column and the foot pad.

If you find that the abnormal sound comes from under the steering wheel when you hit the steering wheel, you should check the steering column and the car mat, because the mat installed behind the car is too large, and there is direct contact with the steering column, with the rotation of the steering column will produce friction, if there is a lack of lubrication, there will be friction sound, in this case, as long as you apply some lubricating oil.

2. The airbag hairspring is faulty.

If you find that the sound is coming out of 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.

3. Lack of oil in the plane bearing of the shock absorber.

When playing the steering wheel, if you find that the abnormal sound is coming from outside the car, it may be the sound of lack of oil in the plane bearing of the shock absorber. All you have to do is 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 coming from the flat bearing of the shock absorber.

If the shock absorber plane bearing is short of oil, you can apply some butter, if it still rings after coating, it can only be replaced.

4. The glue of the balance bar is loose.

If the sound is not emitted from the plane bearing of the shock absorber, it is necessary to 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 the direction, but also make a sound when crossing the uneven road, the loosening of the balance bar glue can be solved by adding a gasket, if it is damaged, it can only be replaced.

on the Internet).

5. The steering power oil is too dirty.

If the booster oil is too dirty, it will increase the pressure of the booster system, and the booster pump will make a "buzzing" sound, and the steering booster oil should be replaced in time.

6. The abnormal sound made by the rebound card after hitting the turn signal.

If you hit the steering wheel after the turn switch is turned on, there will be this sound, that is, the sound of the rebound clip of the turn signal automatic return mechanism. But this sound is the most normal, along the steering wheel will be a pimple sound, the steering wheel will turn around it will appear three pimple sounds, because the direction column has a circle of three automatic return card positions, so this sound will appear. At this point, the sound will disappear as soon as you turn off the turn signal.

1. The steering tie rod ball joint is aging, and there is a large amount of room to replace the steering tie rod ball joint, but remember to do four-wheel alignment after replacement.

2. If the dust jacket of the steering machine leaks, replace the dust jacket or re-butter it. Buttering is only a stopgap measure, though.

3. If the steering machine is faulty, if there is a "cluck" sound when hitting the direction, it may be that the gear gap between the steering machine and the gear is too large, and the steering machine can be replaced.

4. When the plane bearing is faulty, there is a "special tete" sound, which is likely to be the failure of the shock absorber top rubber or plane bearing, and it can be replaced.

5. Improper tightness or aging of the booster beltFor mechanical hydraulic assistance, if the tightness of the belt is improper or aging, there will be abnormal noise, and the belt can be adjusted or replaced.

6. If the steering oil is too dirty, it will increase the pressure of the power assist system, and the power pump will have a "buzzing" sound, and it is OK to replace the power assist oil.

1. The abnormal sound of hitting the direction in situ should be the sound of the speaker line under the steering wheel conducting the spring steel sheet rubbing against the steering wheel, usually the sound comes from inside the car and is a rustling of metallic 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 is a rattling sound, it is the abnormal sound caused by the excessive wear of the car's half-shaft cage, and it is time to replace it.

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

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:

1) When the tires are wheeled on the spot, the friction between the tires and the foreign body on the ground will produce abnormal noise.

2) The steering ball joint is damaged or loose.

3) There will be a sound when the hydraulic work of the assistant system.

The causes of abnormal steering sound are steering gear failure, front shock absorber bearing failure, steering power pump failure, you need to go to the repair shop to determine where the abnormal noise comes from before it can be repaired!

When driving a vehicle, we often notice unusual noises and abnormal vibrations. These faults are usually reflected on the steering wheel, and it is not too much to compare the steering wheel to a fault diagnostic device for a car. However, when there is vibration or unusual noise, is there a problem with these parts?

Many car owners do not recognize it, today teach you how to find out the cause of the fault from the steering wheel.

1. Abnormal sound occurs after turning on the steering switch.

Symptom: We turn on the steering switch and then turn on the steering wheel. Normal is not any abnormal sound; And suddenly you hear an abnormal sound of "click, click" from under the steering wheel, then it is abnormal!

Cause analysis: Since there will be abnormal sounds after the steering switch is turned on, we should analyze the reasons related to the switch. After removing the steering wheel, we turned on the steering switch and found that the aftertaste device of the steering switch was faulty, causing the steering wheel to interfere with the switch return device in the left and right directions, resulting in abnormal noise.

2. "Squeak" abnormal sound in the left and right directions.

Fault phenomenon: When the car turns left and right, people find that there is a "squeak" friction sound under the steering wheel, and the abnormal sound is similar to the rubber friction sound. Whether in the same direction or in the direction of travel, there will be an abnormal sound.

Cause analysis: This sound is mainly caused by the interference friction between the propeller shaft and the dust cover. There are two reasons for this, one is that the dust cover is installed at an abnormal angle and has abnormal friction.

The second is the lack of grease here. In general, if these two problems are solved, the anomalous noise can be solved.

3. The lower part of the steering wheel makes a "rustling" sound.

Fault phenomenon: "rustling" friction sound appears in the lower part of the steering wheel, when the left and right directions are hit. Anomalous sounds are present from all angles, and are louder when the steering is faster.

Cause analysis: If the sound appears under the steering wheel, it proves that the sound is related to the airbag spiral cable tubing. It is usually caused by damage or lack of lubrication inside the spiral cable.

Since the spiral cable cannot be disassembled and repaired, after the abnormal noise, if it is confirmed that the internal fault of the spiral cable is confirmed, it can only be replaced, and cannot be repaired by itself.

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.

If there is an abnormal sound on the front wheel when playing the direction, it may be that the car is out of order. There are several possible reasons for the abnormal noise:

1. Caused by lack of lubrication or damage to the front wheel bearing.

2. The gear clearance of the steering machine is too large, causing noise.

3. The sound of the turn signal returning. If the turn signal is turned on at the same time when steering, then the sound may be the sound of the rebound clip of the turn signal automatic return mechanism, this situation needs to be confirmed by the car owner, if it is the sound of the turn signal, then this is a normal situation.

4. Friction between plastic parts. Steering wheels are usually made of plastic, and if the temperature gets cold, the plastic will harden, which may cause friction noise.

5. There was an abnormal noise in the steering wheel. If the abnormal noise comes from the steering wheel, then the problem is most likely caused by the airbag hairspring in the steering wheel.

6. The ball joint of the steering tie rod is aging. If the ball joint of the steering tie rod is aging, it will cause the steering wheel of the car to shake.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound. Workaround:

Abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment. Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

When this happens, you need to check the flat bearings of the shock absorber and the ball joints of the suspension system.

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.
