What is the cause of abnormal noises when the car is turning?

If there is an abnormal sound in the direction of the car, it may be a malfunction of the airbag hairspring in the steering wheel; The ball joint of the steering tie rod is aging and has spaciousness; oil leakage from the dust jacket of the steering machine; Improper tightness or aging of the booster belt; The steering power oil is too dirty. If there is a problem of abnormal noise in the direction of playing, we can only find out the abnormal sound and determine the location of the abnormal sound in order to have a better solution.

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.

If you hit the steering wheel and hear the sound is made from outside the car, this may be the sound of the plane bearing of the shock absorber is short 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, so that 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.

If the sound is not 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. Friction between plastic parts.

Because 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.

2. Abnormal noise coming from the steering wheel.

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.

3. The ball joint of the steering tie rod is aging.

If the steering tie rod ball joint is aging, then it will cause the steering wheel to shake and make a sound, which is usually replaced by the steering tie rod ball joint and the four wheel alignment after replacement.

4. The abnormal sound emitted by the balance bar.

If it is not the sound of the shock absorber, then 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 gaskets, and if it is damaged, it can only be replaced.

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

Just 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, the plane bearing of the shock absorber sounds, you can apply some butter on the plane bearing, if it still rings after coating, it can only be replaced.

6. Steering machine failure.

If the abnormal noise during steering is very large, then it may be caused by too large gear clearance between the steering machine and the steering machine, and the steering machine needs to be replaced.

7. Improper tightness or aging of the power belt.

For mechanical hydraulic assistance, if the power belt is not properly tightened or aged, there will be an abnormal sound, adjust the belt tightness or replace the belt.

If your car has abnormal noise when turning, you can judge from the above reasons, the owner pays attention to the maintenance of the car every day, and it is not very convenient for the owner to overhaul it.

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.

There is an abnormal sound when playing the direction 1, the friction between the plastic parts 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, it is good to run in for a period of time. 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 is sometimes too large and directly connected to the steering column.

The reasons why the car rattles when steering are:

friction between plastic parts;

There is friction between the steering column and the foot pads;

Failure of the airbag balance spring in the steering wheel;

The ball joint of the steering tie rod is aging and has spaciousness;

The gear clearance of the steering machine is too large. 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, it is good to run in for a period of time, if there is abnormal sound after running-in, you can try to reinstall the steering wheel. If the installed foot pad is too large and in direct contact with the steering column, the steering column will produce friction and make a sound when it rotates, which is a very common situation, and the foot pad can be adjusted or replaced.

The inside of the vehicle's steering machine is damaged, and the internal gear mechanism is faulty.

If there is a failure in the suspension of the vehicle, such as the shock absorber top rubber bearing, the loose ball joint of the upper and lower swing arms, etc., it will also cause abnormal sound in the direction or over uneven roads. Generally, checking the chassis can detect problems.

A loose balance bar or balance bar ball joint may also cause abnormal noises.

If it is mechanically hydraulic, it may be that the booster pump or belt is making an abnormal noise. Generally, when turning, the pressure of the system will be very high, and the mechanical hydraulic booster pump will have a large working load, which is easy to produce abnormal noise.

In the case of electric power assist, the internal power assist motor or other rubber parts may be damaged.

The fixed rubber sleeve of the steering machine is loose or loosened in other places, such as the ball joint in the direction machine or the ball joint outside the direction machine is loose.

1.It may be that the airbag hairspring in the steering wheel is faulty, and if the airbag hairspring is removed, if there is no abnormal noise, this is the case.

2.It may also be that the installed mat is too large and is in direct contact with the steering column to produce friction and make a sound, which is simple, and only needs to replace the pad.

3.It is also possible that the steering tie rod ball joint is aging and there is room to replace the steering tie rod ball joint, but don't forget to do four-wheel alignment after replacement.

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

There is an abnormal sound when the car is turning, it may be because of the transmission shaft connected to the steering wheel, the steering tie rod connected to the transmission shaft, and the ball head at the upper end of the rod has a problem, and the ball head is seriously worn, so it is necessary to replace the ball head of the steering tie rod.

This specific observation is the most abnormal noise, the greatest possibility is caused by serious wear of the steering pressure bearing, it is recommended to go to a professional repair shop to check and repair, hope.

The main reasons for abnormal noise in the steering system and steering wheel of the vehicle are as follows:

1. The steering fluid model is incorrect or missing; 2. There is air in the steering hydraulic system (pipeline); 3. The internal gear of the steering machine is loose or worn; 4. The steering oil pump is worn or damaged; 5. The ball joint of the straight tie rod is worn or damaged; 6. The universal joint of the steering string is loose; 7. The ball joint of the tie rod is worn or damaged; 8. Insufficient tire pressure or tire wear.

Solution: Damaged parts should be repaired or replaced in time, and contact the nearest service station for processing.

Principles of automotive steering

It is mainly to use the steering wheel to drive the steering machine, and then make the rack and pinion steering device function, so that the front tie rod swings left and right to make the front wheel produce an angle and thus the steering effect occurs. A car steering system is a system used to maintain or change the direction in which a car is traveling or reversing.

Automotive steering systems are divided into mechanical steering systems and power steering systems. The mechanical steering system uses the driver's physical strength as the steering energy, and all the force transmission components are mechanical. The mechanical steering system consists of a steering control mechanism, a steering gear, and a steering transmission mechanism.

Power steering is a steering system that uses both the driver's physical strength and engine power as steering energy. Under normal circumstances, the energy required for steering is only partially provided by the driver, while most of it is supplied by the engine through power steering.

The reasons for the abnormal sound when the car is steering are caused by the aging of the belt, the hairspring, the dirty power oil, the internal damage of the spiral electric digging cable, and the aging of the rubber sleeve.

1. Causes of belt aging: abnormal noise is heard due to improper tightness or aging of the automobile power belt; Adjust the belt tightness or replace the belt in time.

2. Caused by the hairspring: if the abnormal noise comes from the steering wheel, it is caused by the airbag hairspring in the steering wheel; Remove the steering wheel airbag hairspring in time and apply butter.

3. Reason for boosting oil: because boosting oil will increase the pressure of the booster system, the booster pump will hear abnormal noise; The booster oil should be replaced in time.

4. Internal damage of spiral cable: caused by internal damage or insufficient lubrication of spiral cable; It should be repaired or replaced in a timely manner.

5. Caused by the aging of the rubber sleeve: the aging of the rubber sleeve of the suspension balance rod of the automobile chassis; Replace the rubber sleeve of the balance bar lifting lug of the chassis suspension in time.

Technical characteristics of the steering system of the car.

In the process of driving, the car needs to change the direction of driving frequently according to the driver's will, that is, the so-called car steering. As far as wheeled vehicles are concerned, the method of realizing automobile steering is that the driver deflects the wheels on the automobile steering axle (generally the front axle) at a certain angle relative to the longitudinal axis of the automobile through a set of special mechanisms. When the car is driving in a straight line, the steering wheel will often be affected by the lateral interference force of the road surface, and automatically deflect and change the direction of travel.

At this time, the driver can also use this mechanism to deflect the steering wheel in the opposite direction, so that the car can return to the original driving direction. This set of special mechanisms used to change or restore the direction of the car is called the automobile steering system (commonly known as the automobile steering system). Therefore, the function of the steering system of the car is to ensure that the car can steer according to the driver's will.

1. There are many reasons for abnormal noise during steering, such as steering wheel, transmission shaft, or tires, and even temperature.

2. If there is a gurgling sound when steering, it may be that the steering tie rod ball joint is aging, and the steering tie rod ball joint needs to be replaced, and the four-wheel alignment must be done after replacement, or it may be that the soft rubber pad is worn, and the sound generated by friction between the machine parts and the machine parts needs to be adjusted or replaced. If there is a gurgling "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. If the above situation is excluded and there is a sound, it may be because of the swing arm and half shaft, the direction machine, you can make a detailed inspection of the chassis to ensure the safety of driving.

3. It is recommended that no matter what kind of abnormal noise, first go to the maintenance shop for inspection, because the abnormal noise when playing the direction is likely to affect the steering system of the car, and if you ignore the maintenance, it is very likely to cause steering failure.

Friction between plastic parts, friction between steering columns and floor pads, and steering gear failures can all cause abnormal steering noise.

1.Friction between plastic parts.

This abnormal noise is associated with temperature changes. When the temperature drops, especially in the northern winters, the plastic hardens and friction makes unusual noises. In addition, this can also be the case with new cars.

Steering wheels are made up of various plastic parts. If the gap between the steering wheels is too small when turning, there will always be friction, and running for a while will be fine.

2.Friction between the steering column and the foot pads.

This is very common. If the foot pad installed on the rear of the car is too large and comes into direct contact with the steering column, friction will occur as the steering column turns. Simply adjust the position of the foot pad or replace the foot pad.

3.Steering machine failure.

If there is a lot of abnormal noise during steering, it may be caused by too large gear clearance between the steering gears, and the steering gear needs to be replaced.

4.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 "humming" noise, and the steering booster oil needs to be replaced in time.

5.Improper tightening or aging of the power belt.

For mechanical hydraulic assistance, if the power assist belt is not properly tensioned or aged, an abnormal sound will be heard, and the belt tension needs to be adjusted or replaced.

6.Shock absorber plane bearing squeak.

Simply open the hood and listen to see if the sound is coming from the shock absorber top seat, so we can know if it's the sound coming from the shock absorber flat bearing. If the flat bearing of the shock absorber makes a sound, you can apply some butter to the flat bearing. If it still sounds after painting, you can only replace it.

7.The balance bar makes an unusual sound.

If it is not the sound made by the shock absorber, check the balance bar glue for loose or damaged pieces. If it is loose or damaged, it will make a sound not only when driving in the direction, but also when passing through uneven road surfaces. If damaged, it can only be replaced.
