What's wrong with the abnormal sound of the car?

The way to judge the abnormal sound of the gearbox is that if the car makes noise at idle speed, the noise disappears after stepping on the clutch, indicating that the source of the noise is caused by the failure of the gearbox; for automatic transmission models, if there is a rustling sound inside the gearbox, the accelerator transmission will not sound. , then it is very likely that the gearbox has made a strange sound.

The abnormal noise caused by tires is generally tire noise, and the noise produced will also produce various noises of different strengths and weaknesses depending on the speed of the car, tire type, tire pressure, road surface and other factors.

Models equipped with turbocharged engines are different; models equipped with engine guards may also make noise due to friction; some car owners may mistake reasonable abnormal noises for vehicle failures due to their lack of understanding of mechanical knowledge after contact with different cars. Therefore, learn to distinguish abnormal car noises to avoid wasting time and energy.

Abnormal sound of the car body. This problem is usually caused by insufficient rigidity of the body, resulting in deformation of the vehicle while driving, friction or shaking of the door and the frame, or friction between the steel plates due to dewelding in some places.

Abnormal car noise is an abnormal phenomenon, which is a manifestation or precursor to car failure.If there is abnormal noise in the car, it must be that some parts are abnormally working or damaged, so once there is abnormal noise, the owner must check it. Abnormal noise is related to the driving performance and service life of the vehicle.

There is a strange sound when the car is driving. What is the reason?

Reason: There is a problem with the shock absorber. There is a rhythmic sound during driving. The reason is the friction sound caused by the gap between the brake skin and the brake disc is too small. The abnormal sound is not obvious when driving at low speed, and the abnormal sound is even when driving at high speed. Reason: This phenomenon occurs when a wheel bearing of the vehicle is damaged.

The models equipped with turbocharged engines are different; the models equipped with engine guards may also make noise due to friction;After contacting different cars, some car owners are likely to mistake reasonable abnormal sounds for vehicle failures due to their lack of understanding of machinery.

Sometimes it may be because the parts of the car body are not fixed, causing abnormal noise. In this case, you only need to tighten the screw. Tire abnormal sound If the vehicle hears abnormal tire noise during driving, the sound can be estimated by the sound.

Abnormal noise in cars is a relatively common phenomenon, because there are many parts, and it is inevitable that there will be aging and loosening. If there is a strange noise in the car during driving, it is better to stop and check it, and make sure that it is normal before continuing to drive. If the noise is particularly loud, especially the noise from the engine, don't continue driving.

What's the problem with the abnormal sound of the brakes while driving?1. Maybe your car hasn't been driven for a long time, and the brake pads are rusty. There is a strange noise when you start braking. After a period of distance, the brake disappears after stepping on the brake several times.

What's the matter with the buzzing sound of the car?

This may be caused by resonance in some parts of the body. If there is only a buzzing sound in a certain speed range, it is resonance. If there is a buzzing sound at any speed, it is emitted by a certain part of the car body. The source of the abnormal sound should be found and repaired.

The exhaust pipe leaks. When the intake and exhaust pipe leaks, the vehicle accelerates and the exhaust rate accelerates. At this time, the vehicle will make a loud roar.

The main reasons for the buzzing sound when the vehicle is driving are as follows: the tire pressure is too high to cause abnormal noise. When using the car on a daily basis, the tire pressure should be adjusted within the standard value range (generally 3bar-5bar). If the tire pressure is too high, it will cause serious wear of the crown and the shock absorption and cushioning performance of the tire will decrease. , the tire noise has increased significantly.

Check the tire bearing and operate it specifically. Drive the vehicle to the lifting platform, hang the idle gear, do not pull the handbrake, stick the ear to the edge of the tire, and use one hand to rotate the 4 tires in turn. As long as you hear a "buzzing" sound, it means that the bearing of the tire is broken. Remove it and replace it.

The reason for the buzzing of the car: It is caused by the wear and looseness of the wheel bearings of the car. It is caused by the tire grinding and eating the tire. Wheel bearing is a simple butImportant auto parts, it can make the wheels rotate freely, and the broken wheel bearing should be replaced before it can be used to avoid damage to the car and injury.

The strange sound you heard is likely to be emitted by the vibration of the storage you lead pin item. Abnormal sound source two: transmission mechanism.

There is a squeaky sound when the car is driving

If there is a "squeaky" sound when stepping on the brake, it is mostly caused by excessive wear of the brake pads, resulting in undue gaps. Of course, improper use or deformation of the brake disc material, unqualified hardness, porosity, friction characteristics and compression characteristics of the brake disc may lead to abnormal noise.

Poor brake circuit: When the car is driving, the squeak is usually caused by poor braking return.If it is the sound of the tire, there may be foreign objects on the tire, such as stones and cans sticking to it. If the brake pads make an abnormal sound, it is likely that the brake pads are almost worn out and need to be replaced in time.

The reason for the squeaking sound at the bottom of the car when the car is driving is caused by abnormal contact and friction between the brake disc and the brake pad. According to the analysis of previous maintenance cases, most cases are caused by the following reasons, one of which may be due to the poor return of the brake pump. As a result, brake discs and brake pads.

The squeaky sound of the car may come from the suspension. The suspension of the car includes a connecting rod, a spring, a shock absorber and a balance bar. If one of the parts is abnormal, such as a loose bolt, it may make a strange sound due to shaking.

How to solve the sound of the car

1. Paste adhesive strips on the doors and windows or put rubber on the friction part and other methods may It can reduce or eliminate abnormal sound, but it can treat the symptoms but not the root cause. Some cars have a lot of wind noise, which is related to the shape. If it is confirmed that no redundant items have been added, the owner will not find a way to solve it by himself.

2. The abnormal sound of the suspension generally cannot be solved by yourself. You need to go to the repair shop or 4S store to ask a specialized master to replace the parts. If it occurs, it must be solved as soon as possible. It is best to strengthen the inspection in daily maintenance to eliminate the occurrence of abnormal noise.

3. The solution is to determine the location and cause of abnormal noise. If plastic products harden and cause abnormal noise in cold weather, you can use some rubber pads or paper pads to solve it, and it is better to stick some 3m glue. It is recommended not to disassemble the interior as much as possible. The first task is to find out the source of noise.

4. Tips to reduce car noise. When we usually drive, we inevitably hear all kinds of noises, such as wind noise, tire noise, etc., which will feel very noisy and affect our mood. So what are the ways to reduce car noise? There is a lot of noise produced by cars, and noise is very destructive as an environmental pollution.

5. You can roughly find the abnormal sound source. After finding the abnormal sound source, you can solve it by yourself without wasting money. Here, I will tell you several common methods to solve the abnormal sound in the car.

6. Solution: If there is a "squeak, squeak" sound when stepping on the brake, it is mostly a warning sound from the wear indicator of the brake friction pad, which indicates that the brake friction pad has exceeded the usage limit.
