What happens when the car is driving in a pothole and the left front wheel makes an abnormal noise?

When the car is driving on a pothole, there is an abnormal noise on the left front wheel. The reason is that the stabilizer bar rubber sleeve is aging or damaged, deformed, and the gap is increased.

In order to ensure the ride comfort of the car, the suspension height is generally designed to be relatively low, so that the driving of the car is more stable. When the stabilizer bar rubber sleeve is aged or damaged, deformed, the gap increases, and loosens, it will cause the front wheel to make an abnormal noise on the potholes and uneven road surface. The small connecting rod of the stabilizer bar, also known as the anti-roll bar and the balance bar, is an elastic element in the suspension of automobiles and plays a very important role in driving.

Therefore, the suspension system adopts a lateral stabilizer structure to improve the suspension angle and reduce the body inclination. A stabilizer bar is a torsion bar spring that is made of spring steel.

Made in a "U" shape, spanning the front and rear of the car. Rubber bushing in the middle of the rod body.

Hinged to the rod body or frame, the ends are connected to the suspension guide arms by rubber pads or ball pins at the ends of the sidewalls.

In addition, check the flat bearing of the shock absorber for abnormal noise. Shock absorber.

After the top rubber is aged and falls off, when the vehicle shakes up and down when passing through potholes, the shock absorber will directly collide with other components, making abnormal noises, and may further damage other parts. Therefore, it is better to carry out maintenance in time.

In addition to the deterioration of the cushioning rubber, damage to the shock absorber will also cause the car to make abnormal noises when passing through potholes. Although the service life of the shock absorber is relatively long, it is also a wearing part on the car; If you're driving on a rough road or driving roughly, it's hard to avoid damage or oil leaks. As long as you open the front cover and listen to the position that the sound does not come from the top seat of the shock absorber, so that you will know whether it is the abnormal sound of the shock absorber bearing, or the abnormal sound of the bearing of the shock absorber, you can grease it on the plane bearing, if it is not solved, it can only be replaced.

If the cushioning rubber is aging, the rubber can be replaced; If the shock absorber is damaged or leaking, the shock absorber will need to be replaced. It is best to choose original parts for replacing shock absorbers, and the quality of original parts is more reliable.

It may be because the front wheel is stuck with something, or there may be some fault in the front wheel, or it may be that the front wheel and the chassis are bumping, or the front wheel of the car has crushed something, so there will be abnormal noise.

It may be because there is a problem with your tire, the tire is bulging, or the screw is loose, so there is a sound.

It may be that there is a ball head in the chassis of your own car, which is a little loose. Or there is an oil leak in the pressure reducer, which should be checked immediately.

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.

Introduction: Vehicles have entered every household, and China's total road mileage ranks first in the world. Today, with the continuous construction and construction of roads, more and more funds are invested in road maintenance projects.

Because the quality of a road has a profound impact on the speed of traffic and traffic obstruction. In some vehicles, if the driving section is driven through potholes, then there will be some noise in the car, and even damage to the vehicle. Let's take a look at what causes abnormal noise in the car?

1. Wear and tear. If the driver buys a vehicle that is a small car, not an SUV or an off-road type, the chassis is very low. Then the suspension design of the vehicle is made up of a shock absorber.

The following triangular arm constitutes a suspension, the main function is to connect the frame with the axle together, play a cushioning role, since it plays a cushioning role, then it means that this frame has a certain service life, and has a shock-absorbing effect on the vehicle. For example, rubber will deteriorate after a long period of use, which means that the steering wheel.

It is unstable, and there will be a phenomenon of fetal eating. <>

2. Sundries. First of all, it is necessary to eliminate whether there are other debris in the car, at just a certain frequency or amplitude.

There is an impact sound in the case of radio waves, or due to a large difference in the ground, the suspension driving compression has reached the specified position and. There is an impact on the ground, or an impact occurs when the engine mount is aging and then vibrating, and the cushioning of each component is reduced to produce abnormal noise. Suspension system.

The aging of the shock absorber reduces the inhibition effect on the spring, resulting in some unnecessary vibration and abnormal noise. You can let the after-sales staff of the 4S store check them one by one. <>

3. Body. Another reason is that because of the intense friction between the door and the door and window, the uneven friction of the road surface is more intense, or there is a place for dewelding to produce friction, some car owners choose to paste rubber strips on the doors and windows or pad the rubber pad on the friction part, so that the symptoms are not cured, and the wind noise of some cars is very large, which is related to the shape. There are also some cars where the body parts are not fixed well, which may also cause abnormal noise, which can be solved by tightening the screws.

When the car passes through the pothole, the car will produce a certain amount of bumps, which may be due to the fact that there are some small parts in the car, and when the vehicle is bumpy, it will produce a throwing sound, and it may be that some parts of the car are missing or damaged, resulting in some swings in the bumpy process.

It is because the vehicle is driving in the pothole, the vehicle bump is too serious, so it will cause abnormal noise in the car, which is very normal.

The reason for this situation is generally that the shock-absorbing top glue or the side rod of the balance bar is broken, and you can go to the 4S shop for repair and replacement.

There may also be the chassis, where the screws are not tightened, so some sound will occur during walking.

There are many reasons for this:1. There is a foreign object between the brake disc and the brake pad of the vehicle, which is a pebble or water film.

2.The brake pads of the vehicle are seriously worn and need to be replaced in time. 3.

The vehicle has insufficient tire pressure. 4.The vehicle's rear suspension is loose or the shock absorber is leaking.

How to deal with abnormal noise of motor vehicles.

It is necessary to find the source of abnormal noise of motor vehicles in the first time and solve the abnormal noise of motor vehicles through the source. If there is an abnormal noise of a motor vehicle, the vehicle can only be used normally after treatment, otherwise it will bring safety hazards to the vehicle. You can drive slowly on a bumpy road to identify unusual noises.

Can motor vehicle squeak be repaired free of charge?

As long as it is within the normal warranty period, the vehicle can be repaired at any four S shops of the vehicle brand. If you need to replace any accessories, you don't need to pay anything. This is a free maintenance project. Once the warranty period is exceeded, maintenance and testing are charged.

Millions of car purchase subsidies.

<> "There is an abnormal noise on the front wheel of the vehicle while driving, and there is a problem.

The car is driving on the road, and after a long time, it will always encounter various problems, some small problems can be dealt with and repaired if the owner can find them in time, and some problems need to go to the repair shop to solve. Old drivers will judge whether there is a fault by listening to the abnormal noise on the car, this is because they have been running on the road all year round and have accumulated a lot of experience, so they can stop the loss in time when the vehicle has not yet obvious fault.

First, the faulty parts are different depending on the sound. When there is a clicking sound in the front tire, this sound generally becomes rapid with the acceleration of the vehicle's speed, which is usually a problem with the tire itself.

If you often drive on the gravel road, it is very likely that there will be some small stones stuck in the middle of the tire pattern, as the tire continues to put pressure on it, the card is getting tighter and tighter, how to rub it has not fallen, and it has been stuck in it and rubbed against the tire and the ground, so you will always hear a clicking sound. At this time, as long as you need to check it after stopping, you can remove the original stones or other foreign objects, otherwise it will cause damage to the tire in the long run.

The second: a buzzing sound from the position of the tire. The sound that occurs is not actually emitted by the tires, but by the shock absorber bearings on the top, which would have been accompanied by the situation of passing through the ground to alleviate the bumps caused by the road conditions to the vehicle, so that the occupants of the car can feel more comfortable.

It also has a breakdown, you need to drive the car to the repair shop to the professional repair personnel for diagnosis, if it is broken, the bearing needs to be replaced, of course, Suichun does not rule out that there may be a problem with the tire, but the probability is relatively small.

The third type: when the vehicle is driving slowly, the squeak of the tires, this sound is relatively small, and the careful owner can still hear it, and the sound seems to disappear when the speed increases. The reason is that the brake pads are worn too seriously, and there is a situation of high and low on one side, so there will be slight friction with the brake disc when driving, and this sound disappears after replacing the brake pad running-in, and then it is possible that the tire part is stuck with a foreign body, and the foreign body is rolled into the middle of the wheel hub and the brake system during driving, so you can get out of the car to check one by one after hearing the abnormal noise, and you can always find out the problem.
