What s wrong with the rattling sound of the car s steering wheel being killed

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 sound you said is to stay in place and kill the direction of the sound, first see if the power pump belt is not tight enough, if it is the direction of the death of the car sound, it is recommended to check the outer cage first.

Direction machine or lower arm, look for the lift, rise up and see.

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 on the spot, the friction between the tires and the foreign body on the ground will produce abnormal noise.

b.The steering ball joint is damaged or loose.

c.When the assistant system hydraulics work, there will be a sound.

Hello, this should be the sound of the steering power at the limit of the steering is normal, generally a lot of oil can be, if you are not assured, it is recommended to go to a professional repair shop to check and listen, find someone who understands a little.

Normal, because it is power steering, when the direction is killed, the vehicle steering power pump is still pressurizing, in fact, the steering gear has come to an end, so make a sound, it is recommended not to kill the direction, especially the direction for a long time!

Pay attention to two aspects of the problem, 1If it is not enough to replenish the standard scale, if the booster oil is discolored, it should be completely replaced. In addition, you should pay attention not to hit the direction to the limit (left or right) at ordinary times, as hitting the limit booster itself will make an abnormal sound, which is not good for the booster and is easy to cause damage.

2.As for whether the front wheel ball cage bearing is damaged, it can be judged in this way: in the process of driving, the direction of turning, especially the smaller the turning radius, the easier it is to judge, whether left or right, if there is a "click, click, click" rhythmic abnormal sound, it means that the ball cage bearing is broken.

Because your steering machine is still working and can't rotate, there is a sound, try not to kill it, it will hurt the steering machine.

Generally speaking, your front-wheel drive car is more likely to have this situation, and it may be that the cage is severely worn. It is recommended to check the cage, because I don't know what model it is, I don't know if there is a balance boom, and a loose balance boom will also produce abnormal noise, it is best to check it, the possibility of the cage is a little greater! Thank you!

Landlord: That's your direction, the help oil is gone.

There are many reasons for the abnormal noise of the steering wheel, depending on the situation. When there is an abnormal sound in the direction of the car, it is likely that the steering or chassis parts are faulty or damaged, so you should go to the 4S shop or repair shop for inspection and maintenance in time to avoid affecting driving safety.

1. In the case of left or right killing, the sound becomes louder, which may be due to the abnormal sound of the steering power pump. It is necessary to check whether the steering power oil is missing. In addition, our electronic steering machine will have a buzzing sound when it hits the left and right directions.

This is the sound of the steering machine working between the rack and the tooth fan, and the steering machine needs to be replaced.

2. When playing the direction, the chassis has a gurgling sound, which may be due to the steering tie rod ball joint or the chassis control arm clearance. There is also a situation that the gap between the top rubber of the shock absorber is too large, and there will be abnormal noise when hitting the direction. In addition, the steering column airbag slip ring under the steering wheel is damaged, and there will be a rattling sound in the direction, which is likely to be accompanied by an alarm of the airbag light.

Of course, there is a sound that is normal, that is, when you hit the direction in situ, there will be friction noise between the tire and the ground, this sound will be significantly reduced when the vehicle is driving, and the friction sound will become louder when you hit the direction in place, so this situation is normal and there is no need to worry.

Car Maintenance:

1. Maintenance of automobile engine.

The engine of the car should be cleaned at the right time. Because long-term use will form a thick layer of carbon deposits on the surface of the engine, which will cause greater corrosion to the rubber parts in the engine.

Second, both gasoline and water should be protected from evaporation.

In summer, the temperature is generally high. So both gasoline and water evaporate more easily than usual. Because the water tank and fuel tank should be checked frequently, and when the gasoline and water are relatively small, they should be added in time.

1. Sounds coming from inside 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 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.

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, the sound coming from outside the car.

1. The sound emitted by the plane 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 balance rod glue loosening.

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.

For the problem of abnormal noise, only by finding out the sound ** and determining the part of the sound can there be a solution.

When the steering wheel is killed, it is relatively common to have abnormal noises, which can come from flat bearings, suspension, and steering gear. If the squeak is from the steering machine, then the steering machine needs to be replaced if you want to eliminate the squeak.

It is recommended that riders usually do not kill the steering wheel when driving, and if they are killed, they can return a little, which is good for the steering machine. It is recommended that riders usually try to avoid hitting the direction on the spot, and it is best to turn the steering wheel back to the right before turning off the engine and stopping.

If the squeak is from a flat bearing, then only the flat bearing needs to be replaced. The cost of replacing a flat bearing is relatively low.

When the bonnet is opened, you can see the top of the tower where the two front shock absorbers are held, and inside the top of the tower there are flat bearings. When steering, the front shock absorber also rotates with it, and the plane bearing also rotates.

The reason for the squeak of the steering wheel in the car is that the balance of the directional transmission inside is broken, or there is excessive wear on the transmission shaft and spline shaft. In medium-speed driving, especially on uneven roads, there are a dozen directions"Click"Sounds or other periodic abnormal noises, abnormal vibrations of the steering wheel, sometimes cause numbness in the hands.

Steering wheel tips:

Make full use of a reference on the front of the car. When the reference object is located in the middle or on one side of the road, it should be able to correctly sense the position of the vehicle at this time, so as to determine the timing and amplitude of hitting or returning to the direction. When driving on the right-hand side of the vehicle, the steering wheel should be turned left to prevent the front of the vehicle from deflecting to the right.

The squeak of the steering wheel of the car may be a problem with the steering ball head rubber sleeve, and it is recommended to check whether the steering ball joint rubber sleeve of the car needs to be replaced.

There may be four reasons for this, you can take a look! First, whether the power assist oil for steering is missing (the power booster pump itself fails).

Second, whether there is a problem with the rod ball joint. (Locate whether the dust-proof rubber sleeve has oil seepage) Third, the steering machine itself is faulty.

Fourth, whether the bolts of the lock shelf are loose.

It can be judged that it is the sound of the belt slipping. The directional hydraulically assisted model has an external booster pump, which is usually driven by the engine belt. The booster pump sends the transmission oil into the power steering while we operate. Hope to adopt

First, whether the power assist oil for steering is missing (the power booster pump itself fails).

Second, whether there is a problem with the rod ball joint. (Locate the dust-proof rubber sleeve to see if there is oil seeping).

Third, the steering machine itself is faulty.

Friction between plastic partsBecause the steering wheel is usually made of plastic parts, if the temperature becomes colder, the plastic will harden, and there is a natural possibility of friction sound.

Safety hazards: 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.

There are many reasons for the rattling sound under the steering wheel, mainly the following: friction between plastics, lack of steering oil, aging of the ball joint of the steering tie rod, etc.

The reasons for the rattling of the steering wheel of the car are: 1. Friction between plastic parts; 2. Abnormal noise coming from the steering wheel; 3. Aging of the ball joint of the steering tie rod; 4. The abnormal sound emitted by the balance bar; 5. The plane bearing of the shock absorber makes an abnormal sound; 6. Steering machine failure; 7. Improper tightness or aging of the power belt. The car has a rattling sound when it hits the steering wheel, which is specifically manifested in:

1. Friction between plastic parts: Because the steering wheel is usually composed of plastic parts, if the temperature becomes colder, the plastic will become hard, and there is naturally a possibility of friction sound. 2. The abnormal sound comes from the steering wheel, because of the airbag hairspring in the steering wheel, remove the steering wheel airbag hairspring and apply some butter to see if it still sounds, and replace the airbag hairspring because the airbag hairspring is damaged.

3. The steering tie rod ball joint is aging, then it will cause the car steering wheel to shake and sound, which is usually to replace the steering tie rod ball joint, and carry out four-wheel alignment after replacement. 4. It is not the sound of the shock absorber, then it is necessary to 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 gaskets, and the damage can only be replaced. 5. 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.

6. The abnormal noise during steering is very large, then it may be caused by the excessive gear clearance of the steering machine, and the steering machine needs to be replaced. 7. For the improper tightness or aging of the mechanical hydraulic power belt, there will be a strange sound, adjust the tightness of the belt or replace the belt.
