What is the reason for the abnormal sound of the steering wheel of the 15 Regal cool cars

Analysis of the causes of abnormal noise when the car is steering, and suggested solutions

1. The friction steering wheel between plastic parts is composed of various plastic parts, if the gap is too small when turning, there will always be abnormal noise, especially for new cars, and it will be good to run in for a while. If there is still an abnormal sound after the run-in, you can try to reinstall the steering wheel.

2. The friction between the steering column and the foot pad Sometimes the foot pad installed after the rear is too large, and it is in direct contact with the steering column, so the steering column will produce friction when it rotates.

3. Friends who have removed the steering wheel should pay more attention to the failure of the airbag hairspring in the steering wheel, which may be that the airbag hairspring is broken or the airbag hairspring plug is not plugged in properly, and the airbag hairspring or fixed plug can be replaced.

4. The steering tie rod ball joint is aging, and there is a space to replace the steering tie rod ball joint, but remember to do four-wheel alignment after replacement.

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

6. If the steering machine is faulty, 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.

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

8. 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.

9. 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 the power assist oil can be replaced.

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.

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.

The reason for the abnormal noise of the steering wheel is the problem of the booster oil, see if the booster oil is below the scale, the oil becomes thin or the color of the oil becomes black, it means that the booster oil needs to be replaced. If you can replace it yourself, first open the front cover of the car and use the oil extractor to suck the old oil clean. Then inject the new booster oil, and then turn the steering wheel back and forth to let the new oil penetrate, in order to penetrate thoroughly, the owner had better turn the direction left and right sharply, and then, and then slightly turn the direction left and right.

However, the purpose of hitting the steering wheel back and forth is to drain the old oil in the steering machine, don't kill the steering wheel for a long time, otherwise the steering oil will spray out. Next, the oil from the booster tank is sucked out, and then a new booster oil is injected, and the steering wheel is turned again. The third time to suck the booster oil away is to make sure that the old oil is completely removed.

Then inject new oil. That's it, verbose: the engine oil can't be mixed.

I sometimes have it, shake the plastic shell and it won't sound 1. Friction between plastic parts Because the steering wheel is usually composed of plastic parts, if the temperature becomes cold, the plastic will become hard, and there is naturally a possibility of friction sound. 2. 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. Be careful to remove the steering wheel gently, or unplug the airbag fuse to avoid the airbag from deploying.

3. Aging of the steering tie rod ball joint If the steering tie rod ball joint is aging, then it will cause the shaking and sound of the car steering wheel, which is usually to replace the steering tie rod ball joint, and carry out four-wheel alignment after replacement. 4. If the abnormal sound emitted by the balance bar is not the sound from the shock absorber, then check whether the balance bar glue is loose or damaged, the loose and damaged balance bar glue will not only 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 a gasket, if it is damaged, it can only be replaced @2019

The main reasons for the abnormal sound of the steering wheel include: 1. The steering column is not lubricated; 2. High friction; 3. Check that the steering power assist oil is less; 4. There is a problem with the universal joint; 5. The chassis suspension balance rod lifting lug sleeve is aging and hardening.

There is a gurgle sound when steering, which can basically be judged as the steering machine due to aging, and it is also a precursor to the failure of the steering system. At the same time, it is also necessary to pay attention to whether there is aging phenomenon in wearing parts such as steering crossbars, ball joints and steering machines, and should be checked and maintained in time to avoid unnecessary trouble.

When the car makes a rattling or other abnormal noise when steering, it is basically caused by the aging of the steering power mechanism. The plastic friction in the steering machine, the reduction of steering power oil, the aging of the ball joint of the steering tie rod, the failure of the steering machine and the aging of the tightness of the belt can all lead to abnormal steering noise. Therefore, at this time, you should go to the professional maintenance shop in time to test the steering power system, otherwise there will be steering difficulties and other failures in the later use.

The solution to the problem of turning the direction is a crack, which can basically be judged to be caused by the aging of the steering machine, and it is also a precursor to the failure of the steering system. At the same time, it is also necessary to pay attention to whether there is aging phenomenon in wearing parts such as vertical crossbars, ball joints and steering machines, and should be checked and maintained in time to avoid unnecessary trouble.

A steering system is a series of devices used to change or maintain the direction in which a car is moving or reversing. The function of the steering system is to control the direction of the car according to the driver's wishes. The automobile steering system is very important to the driving safety of the car, so the parts of the automobile steering system are called security parts.

Automobile steering system and braking system are two systems that must be paid attention to in automobile safety.
