What s the reason for the steering wheel to rattle?

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.

What's the reason for the steering wheel to rattle? What's the reason for the steering wheel to rattle? There is a rattling sound when the steering wheel rotates, and there are many reasons involved, and the common one is that there is a problem with the steering machine and ball head.

It should be noted here that if it is hydraulic power steering, when the steering wheel is killed, the hydraulic power assist pump is under high load, and there will be abnormal noise, which is a normal phenomenon. There are many kinds of ball joints, and different cars have different designs, which are generally divided into two types: tie rod ball joints and connecting rod ball joints. The function of the ball joint is to use the ball connection to realize the power transmission of different shafts, and provide the reason for the rattling sound of the multi-angle steering wheel

1. Abnormal friction of steering wheel horn electrodes; 2. The steering column universal joint is abnormal or the steering column is rubbing against the foot pad; 3. The steering wheel return lever makes abnormal noise. The abnormal friction sound of the steering wheel horn electrode is mostly seen in cars without airbags and only horn buttons on the steering wheel, because the horn switch rotates with the steering wheel, and the horn switch is not moved below the connection line, so it is easy to break the wire when hitting the direction. The abnormal sound of the universal joint of the steering column or the friction of the steering column against the foot pad is due to the fact that there is a universal joint at the front end of the steering column, and sometimes the universal joint will have a rattling sound due to lack of lubrication, and the universal joint needs to be lubricated.

The turn signal has an automatic return function, turn on the turn signal and turn the direction, the steering column will make a clicking sound when it touches the return lever. @2019

There are a lot of gurgling sounds on the left and right steering wheels, and the first thing to distinguish is the part: 1The lower part of the steering wheel may be caused by loose bolts or a lack of lubricating oil.

2.The chassis part of the body, mainly the suspension parts with too large axle head clearance or loose bolts, need to be checked.

What's the reason for the rattling sound when turning?

What's the deal with the creaking noise when hitting the direction? What should I do if the steering wheel of the car makes an abnormal noise?

The reasons for the rattling sound of the steering wheel are as follows: 1. The sound of the steering column rubbing against 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 comes from the steering wheel, it 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 sounds, 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 notice an abnormal noise coming from outside the car, it may be the sound of lack of oil in the plane bearing of the shock absorber. Just open the hood and listen to see if the sound is coming from the position of the top seat of the shock absorber, so that you know if it is the sound of the flat bearing of the shock absorber. If the shock absorber plane bearing is short of oil, apply some butter, if there is still abnormal noise after coating, it can only be replaced.

4. The balance bar is loose. If the sound is not from the plane bearing of the shock absorber, it is necessary to check whether the balance bar is loose or damaged, the balance bar 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 can be solved by adding a gasket, and if it is damaged, it can only be replaced. 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.

1. It is a strange sound in the direction of the in-situ, the dull sound, like a very laborious rotating sound, it should be the sound of the booster pump, generally the oil is less, resulting in insufficient pressure to inhale air.

2. It is still abnormal noise in situ and abnormal noise at the beginning, which should be a problem with the tightness of the booster belt, and sometimes it is a very sharp sound caused by the belt slipping. Sometimes it's a dull hum caused by the belt being too tight.

3. Then there is the sound of the shock absorbing spring caused by the damage of the pressure bearing of the shock absorber, which is like playing the strings of a musical instrument.

4. Then there is the sound of the locking card of the lower steering column, which is because of the sound of the card deformation when it rotates in the direction.

5. There is a friction sound under the steering wheel when you turn the steering wheel, which may be the friction of the shell under your steering wheel, 6. The universal joint of the lower steering column is corroded in only one direction that can be flexible, and the other is not very flexible, resulting in abnormal noise and heaviness of direction regularity.

This kind of abnormal noise is mostly seen in cars without airbags and only horn buttons on the steering wheel, because the horn switch rotates with the steering wheel, and the horn switch is not moving below the connection line, and if the horn switch is also connected with a wire, it is easy to break the wire when hitting the direction.

Therefore, the designers came up with a way to fix the electrode contacts, and then install a round metal electrode on the steering wheel to contact the fixed electrode contacts, so that the steering wheel can transmit electrical signals whenever it rotates.

In order to reduce friction, lubricating oil is installed on the electrode, but after a long time, the electrode contact wears out, and the contact surface becomes larger and larger, which will make abnormal noise. At this time, it is necessary to remove the fixed electrode, and then polish the contact to make the contact surface smooth to eliminate the abnormal noise.

There are many reasons why the steering wheel clicks. The common problem is that there is a problem with the steering gear and ball joint. It should be noted here that if it is hydraulic power steering, when the steering wheel is dead, the hydraulic power pump is in a high load state, and there will be abnormal noise, which is a normal phenomenon.

There are many kinds of ball sections, and different cars have different designs, which are generally divided into two types: tie rod ball knots and connecting rod ball knots. The function of the ball joint is to use the ball joint to realize the power transmission of different shafts, provide multi-angle rotation, make the steering mechanism steer smoothly, reduce vibration, and achieve smooth steering. So, if there is a problem with the ball head, it will cause a heavy blow to imitate the sound of the Qing Kuan.

If the squeak comes from the lower part of the steering wheel, it may be caused by a loose bolt or a lack of lubricating oil.

If the squeak is coming from the undercarriage, it may be that the axle head clearance of the suspension parts is too large or the bolts are loose.

Others, such as the steering column dust cover problem, the airbag balance spring of the bright disc, the plane bearing of the shock absorber, and the balance bar, may cause abnormal noise.

What's going on? We need to go to a 4S shop or a professional auto repair shop to let professionals check and determine the problem of hail, and then analyze it according to the specific problem and repair the symptoms.

Reasons for the position that may cause abnormal noises when turning the steering wheel: the sound of the rebound clip of the turn signal automatic return mechanism; Lack of lubrication of the direction post dust jacket; The airbag hairspring in the steering wheel causes an abnormal sound; The sound of lack of oil in the plane bearing of the shock absorber; The glue of the balance bar is loose or damaged.

1. The sound of the turn signal returning.

If the turn signal is turned on at the same time as the steering, the sound may be the sound of the rebound clamp of the turn signal automatic return mechanism, which needs to be confirmed by the owner, if so, then this is a normal situation. Sometimes you hear more than one sound, because of the amplitude of turning the steering wheel, the steering column will automatically return to the position in three circles, and if you turn the steering wheel once, then it will sound three times.

2. The abnormal sound emitted by the dust jacket of the direction column.

If the abnormal noise comes from under the steering wheel, it may be an abnormal sound from the dust jacket of the steering post. Due to the lack of lubrication of the steering post boot, there is a frictional sound. In this case, the owner only needs to apply some butter in the dust jacket, and the abnormal noise will disappear.

3. Abnormal noise coming from the steering wheel.

If the abnormal sound comes from the steering wheel, 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.

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

If the abnormal sound ** outside the car, it may be the sound of the plane bearing of the shock absorber caused by the lack of oil, as long as you open the front cover to listen to whether the sound is from the position of the top seat of the shock absorber, 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 is still loud after coating, it can only be replaced.

5. The abnormal sound emitted by the balance bar.

If it is not the sound 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, and the damage will not only sound when playing the direction, but also make a sound when crossing the uneven road, 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.

Generally, it is the problem of the general column under the steering machine, and it will be fine if you change it. I changed the car in 14 years. Generally, there will be a sound when you hit the dead back direction.

Turning the steering wheel has an abnormal sound, the more common fault is the steering machine, the ball head has a problem, when the ball head is old, sometimes it will cause the shaking or abnormal sound of the car steering wheel, usually replace the steering tie rod ball head can be solved. If the abnormal sound is at the position of the pipe column under the steering wheel of the car, it may be caused by loose bolts or lack of lubricating oil. If the abnormal sound is in the position of the chassis of the car body, it may be that the gap between the suspension parts and the thick axle head is too large and the bolts are loose.

The rest, such as the problem of the anti-Suisong dust cover of the steering column, the problem of the airbag hairspring in the steering wheel of the car, the problem of the plane bearing of the shock absorber, and the problem of the balance bar, will cause abnormal noise. What is the specific reason, you need to go to a 4S shop or a professional car repair shop, so that professionals can inspect and repair it.

The abnormal sound of the car turning the steering wheel is also related to the change of ambient temperature, it may also be the fault of the steering column, the plastic will harden after the temperature drops, and there will be an abnormal sound when the steering wheel is turned, and there will be friction when the gap is small when turning, and it can be restored to the original state after a while, if it is a normal phenomenon in winter, because the plastic parts on the steering wheel of the car produce friction, causing the gap of the car to be too small when turning, this fault does not need to be treated, Wait for the weather to warm up and you can return to the original state of use, if it is normal to have abnormal noise during the run-in period, it is usually normal to use after the run-in period, if there is also an abnormal sound after the run-in period, you need to reinstall the car steering wheel.
