What s going on with the sound of the car hitting the steering wheel

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 a gurgling sound when turning, it is a problem with the position of the suspension and the ball head, usually after the soft rubber pad is worn, the sound of friction between the parts and the parts, if the above situation is excluded, there is a sound, check the swing arm and half shaft, direction machine and the like, and check the chassis.

If there is a gurgling sound when turning, it is a problem with the position of the suspension and ball joint, usually after the soft rubber pad is worn, the sound of friction between the parts and the parts, if the above situation is excluded, there is still a sound, check the swing arm and half shaft, direction machine and the like, and check the chassis.

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.

Steering wheel squeaks are caused by friction between plastic parts, friction between the steering column and the floor pads, and a malfunction of the airbag hairspring in the steering wheel. Friction between Huaicha plastic parts: The steering wheel is made up of various plastic parts.

If the clearance is too small during rotation, there will always be an abnormal noise, especially in new cars. Just run in for a while. If there is an abnormal noise after the run-in, try to reinstall the steering wheel.

Friction between the steering column and the foot pads: Sometimes the installed foot pads are too large to directly contact the steering column, resulting in friction when the steering column rotates. Inner airbag hairspring failure:

If the balloon balance spring is broken or the balloon spring plug is not inserted correctly, replace the balloon spring or fixed plug. Replace the dust cover or regreas: Oil leaks from the steering gear dust cover can be resolved by replacing the dust cover or regreasing.

Replace the tie rod ball joint, but after the replacement, four wheel alignment is required. Change the steering gear: The steering gear fails, and there is a terrible abnormal sound from the lead skin in the direction of travel, which may be that the steering gear gap is too large and the steering gear needs to be changed.

If there is a gurgling sound when turning, it is a problem with the position of the suspension and ball joint, usually after the soft rubber pad is worn, the sound of friction between the parts and the parts, if the above situation is excluded, there is still a sound, check the swing arm and half shaft, direction machine and the like, and check the chassis. In this case, car owners should carefully investigate, because there are many reasons for this situation, such as the sound of the turn signal returning, which is a normal situation, or it may be the abnormal sound of the steering column dust jacket, the friction between the plastics, the abnormal noise from the steering wheel, the abnormal noise from the plane bearing of the shock absorber or the abnormal sound from the balance bar. If it is the cause of the direction post dust jacket, then only the dust jacket or re-butter is sufficient.

Buttering is only a stopgap measure, though. In addition, because the steering wheel 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 is 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.

If there is an abnormal noise inside the steering wheel, it 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. If it is a plane bearing problem, you can replace it, because the plane bearing is responsible for linking the body and the shock absorber, avoiding direct friction, and also constitutes a component including the dust cover, raceway, ball, etc., which is located at the top of the shock absorber assembly, so it will also cause abnormal noise when hitting the direction. Usually the damage of the plane bearing is a matter of chance, if in case of damage, try to go back to 4S for warranty claims, if the car has been out of warranty, don't worry, spend a few hundred yuan to replace a new one.

When this happens, we also have 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 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

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.

Hello, I am helping you sort out the answers to your questions, please wait a while Hello, I am your exclusive technician, attentive, careful, and attentive to answer your car questions, and find corresponding problem solutions and solutions for you!

Based on your question, the following analysis was conducted.

The analysis solution is as follows:

If this sound occurs when playing in the direction in situ, then it is mainly caused by the damage of your shock absorber pressure bearing, and if there is this sound in the direction during driving, then it is mainly caused by the damage of your half-shaft ball cage, which needs to be judged according to your actual situation. At the same time, listen to the position of the sound, whether it is in the car or outside the car, and if it is in the car, it is possible that the gimbal of your steering machine is broken.

I hope my answer will be helpful to you.

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.

The reason why the car sometimes rattles when it hits the direction is:1. The sound of the rebound clip of the turn signal automatic return mechanism;

2. The friction steering wheel between plastic parts is usually composed of plastic parts, if the temperature becomes cold, the plastic will become hard, and there may be friction sound;

3. The airbag hairspring in the steering wheel is damaged;

4. If the ball joint of the steering tie rod is aged, if the ball joint of the steering tie rod is aged;

5. The gear clearance of the steering machine is too large.

Notes: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 in the direction, but also make a sound when crossing uneven roads, and the loose balance bar rubber can be solved by adding a gasket, and if it is damaged, it can only be replaced.
