Buzzing sound while the car is moving, there is a buzzing sound when the car is moving, what is the

If you hear the abnormal sound of "Zizi" in the process of driving, and this is the abnormal sound caused by the problem of the engine belt, because the abnormal sound of "Zizi" is mostly the aging of each belt group of the engine, or the belt is too loose caused by the problem of the tensioner, the friction abnormal sound, belt slippage, etc., if there is a similar "Zizi" abnormal sound, then look for the major belt groups and tensioners inside the engine, such as engine timing belt, generator belt, circulating water pump belt, air conditioning belt, power pump belt, etc. The problem that causes this abnormal noise is the abnormal sound of the engine belt, which is caused by the smooth grinding surface of the joint surface of the belt and the pulley. It usually occurs when the engine speed changes rapidly, and sometimes the belt rings when the load of the attachment driven by the belt increases.

How to solve the problem of abnormal noise of engine belt.

1. Check whether the accessories driven by the belt are damaged, stuck, loose or the power of the accessories has increased.

2. Replace the belt, or use 100 gauze to polish the joint surface of the pulley and the belt (light grinding is fine).

3. The temporary solution can be to drop 1 2 drops of oil on the joint surface of the belt and the pulley (it will not affect the belt slippage).

If it is the generator belt that rings and the headlights are more obvious, you have to take off the generator belt, turn the motor pulley to see if the generator rotates smoothly, if the generator is normal, you can check whether the battery is not stored power, because the battery storage is not good will increase the load of the generator.

The car may make abnormal noises after driving for a long time, so it is recommended that you go to the 4S shop for a comprehensive inspection to see if there is a problem with the chain, belt or engine.

The car is buzzing while driving, and it is very likely that it is an engine failure.

You need to go to the repair shop to listen to the sound of the actual car to make a judgment.

Hello friends, in this case you should go to the repair shop, let the master use a jack to jack up the four tires, and focus on checking the lost bearings, because the bearings on the wheels are broken, this sound will appear. I hope my answers will help you, and if you have any questions, you can always contact me. BBA Mercedes-Benz BMW Audi Maintenance wishes you a happy life, all the best, and a lot of money!

The main function of the bearing is to bear the load and provide precise guidance for the rotation of the hub, it bears both axial and radial loads, and is a very important component.

First of all, determine the location of the abnormal noise! If the car can be lifted with a lift, one person is in gear in the car, and the other person is under the car to judge the abnormal noise.

If the squeak occurs near the tyre and the wheels and bearings have been eliminated, then there is a possibility that the brake pads and brake discs are rubbing against each other. Generally, the abnormal noise of the brake pad is mostly due to the friction with the brake disc caused by the hard points of the brake pad, and the noise can be ignored if the sound is small; If the noise is loud, you can remove the brake pads and polish them with sandpaper before reinstalling them, and most of them can be solved.

If the sound is at the junction between the gearbox and the engine, it may be an abnormal sound caused by damage to the clutch plates and release bearings. If it is inside the gearbox, then the abnormal noise may be due to abnormal wear of the first and second gear gears.

It should be reminded that repairing a car is the same as seeing a doctor, and it is also important to find an experienced maintenance worker, so that you can definitely avoid detours and shorten the maintenance time as much as possible.

The abnormal sound of the body is usually due to the insufficient stiffness of the body, which causes the door to rub or shake the frame during driving, or the friction between the steel plates is caused by dewelding in some places. Methods such as sticking adhesive strips on doors and windows or padding rubber on friction parts may be able to reduce or eliminate abnormal noises, and if such abnormal noises occur, it is necessary to check as soon as possible to determine the fault point and replace the aging parts to solve it.

Answer Hello dear, 1If the sound comes from the bottom of the car during normal driving, it should be the drive shaft that loses its dynamic balance, causing a buzzing sound. Solution: Remove the drive shaft to do dynamic balancing, or directly replace the new drive shaft.

2.If it is driving it should be the sound of the bearing of the one shaft of the gearbox.

3.If it is a clutch sound, it should be that the clutch release bearing is damaged. Solution: Lift the gearbox and replace the bearing.

Hello, the neutral exercise is the problem of the wheel bearing, the acceleration is the engine mount, in which direction the ring is the bearing of the wheel, just change it.

When the vehicle starts cold, the oil is not fully lubricated in the various parts, the sound will generally be louder, and so the idle speed will be lowered, the sound will be smaller, if the car is hot for a while, there is a sound, consider whether there is a reason for the aging of the belt parts, including whether the engine is used for too long and other reasons, open the hood, find the sound**, and troubleshoot in time, so that the engine can achieve the best working condition.

Hello, buzzing sounds, 90 are all sounds made by tire bearings.

It could be that the hub bearing rang.

Resonance, is it installed with an iron guard.

The buzzing sound of the car while driving is most likely caused by these reasons, so be careful!

The problem you are talking about is most likely the tire noise, which is louder if the tire is harder. Take Goodyear tires, for example.

Hello answer, I have seen your question, and I am sorting out the answer, please wait a while,,, you run the car to 80km, and then slide in neutral gear, listen carefully, if the sound becomes clearer, it can be judged that there is a problem with one of the 4 wheels.

2. If the neutral gear slides and the sound disappears, it is generally a bearing failure of the engine, and the ablation of the bearings in the engine is generally a water pump, generator, and tensioner.

3. If the above situation is not a problem, the car has to be sent to the 4S shop for maintenance to find out the reason, because it is likely to be the sound of the transmission, which is more troublesome and more expensive to maintain.

Listen to your description, which part of the bearing should be caused by ablation. You can test the car like this: 1. You run the car to 80km, and then slide in neutral gear, listen carefully, if the sound becomes clearer, it can be judged that there is a problem with a bearing in the 4 wheels 2. If the neutral gear slides and the sound disappears, it is generally a bearing failure in the engine, and the ablation of the bearings in the engine is generally common water pumps, generators, and tensioners.

3. If you can't find any of the above problems, then your car has to go to the repair shop, because it is likely to be the sound of the transmission, which is more troublesome and expensive to maintain.

Check the tire bearings and do this. Drive the vehicle on the lifting platform, hang neutral gear, do not pull the handbrake, attach the ears to the side of the tire, use one hand, turn 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 main aspects are as follows:

Solution: Some high-grade sound-absorbing foam can be added to the engine cover, which can not only suppress the vibration caused by the hood, but also absorb a lot of noise, and the effect is obvious.

2. Tire noise: tire noise is caused by the friction between the tire and the road surface when the vehicle is driving at high speed, depending on the road conditions to determine the size of the tire noise, the worse the road conditions, the greater the tire noise, and the tire irritability generated by the asphalt road and the concrete road surface is very different.

Solution: tire noise is structure-borne noise, its main generation is vibration, the most reasonable solution is to control the vibration. Adding a damping plate and a sound-absorbing pad can solve road noise and tire noise well.

3. Wind noise: Wind noise refers to the pressure of the oncoming wind in the process of high-speed driving of the car has exceeded the sealing resistance of the door and entered the car. Solution:

Add or replace the door seal, because the seal is a rubber product, which will age after a long time, and the sound insulation and sealing effect will deteriorate.

4. Body structure noise: It is mainly affected by two aspects, one is the vibration transmission mode of the body structure, and the other is the noise generated by the metal components on the body due to the action of inside and outside. Solution:

This situation rarely occurs in new cars, pay attention to check whether the screws of the body parts are loose, and generally can be solved after tightening the screws or replacing the parts.

Abnormal noise 1: the storage compartment in the car, the cluttered and scattered items in the glove compartment or the sound of loose wires installed with electronic equipment, sometimes this sound will be folded back through the roof, which will make you feel that the roof is ringing. Those who have a sunroof will think: I wipe, the sunroof will not fly.

Reason: storage compartments, scattered things in the glove box, even the sunglasses nose bridge in the glasses case will ring, whether your lighter is littered again, and whether the driving record installed in the later stage is a little loose.

Solution: Make a fist and hit a part of the car, and when it hits a certain part, there will be a sound. Determine what is around the entire area, take it out or fix it one by one, and tap it again to confirm.

If the noise disappears, it means that the source of the abnormal noise is the one you took out or fixed.

Abnormal sound 2: Whether it is low speed or high speed, abnormal noise exists, the faster the speed, the faster the frequency.

Reason: It is related to the transmission mechanism, such as tires, cages, etc.

Solution: You can go to the repair shop and get on the lift to find out the cause.

Abnormal noise three: when idling, stand in front of the car with the engine speed to make a "whoosh" noise.

Reason: If you have changed the motor pulley or have not changed the motor pulley for more than 80,000 kilometers, then the reason is very simple.

Solution: It is necessary to go to the repair shop to check that the motor pulley is likely to be aging or unqualified if it has just been replaced.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, happy to answer your questions.

This sound appears on the right front tire while driving. If there is no problem, you need to check the half-shaft cage on the right, including the tire on the right, to see if there is a lot of wear and tear, and to see if there is any tire noise. Mainly check these aspects, as well as the side of the engine, the belt pulley bearing tensioner of the engine in this position, these parts need to be checked.

If there is a problem with the bearing, it will sound when you step together, lift the car up, turn the wheel, and the bearing can be heard. If it is buzzing when running, the speed of the car is slow and you can't hear clearly, the faster it is, the louder it is, most of it is the problem of tire wear, commonly known as eating tires. My 13-year-old Passat, like you, buzzed as soon as the rear wheel passed fifty or sixty, and the faster it was, the higher the frequency, and I went to the repair shop to see that the bearings were not.

The buzzing of the car's license may be caused by a damaged bearing.

The buzzing of the car while driving is 80% likely to be a problem with the wheel bearings.

The specific reasons are as follows: 1. The biggest possibility is the bearing problem! Because bearings are consumable parts, there may be a buzzing sound when the kilometers reach 7-80,000 kilometers.

If the speed is 80-90kmh neutral, if there is a buzzing sound, then it is most likely a bearing problem! Generally, when the wheels are off the ground, the tires will hear! 2. Tire noise will buzz!

It is normal for some tires to have varying degrees of aging after a period of use, but some tires are prone to hum after aging, similar to the abnormal noise produced by bearing breakage. This requires adjusting the tire position before and after the test drive! You can also touch the tread with your hands to see if it feels uneven or bulging!

3.Bridge bearings are damaged! It's unlikely to be a bad thing, but it can't be ruled out either!

This type of bridge bearing is only installed on the right half shaft of some cars. Analyze this specific problem in detail! 4.

Abnormal noise of transmission differential! The sound of this gearbox is quite complex. If there is a buzzing sound when cornering and it is not a bearing problem, consider whether it is a differential problem!

Generally encounter buzz first consider bearings and tires, these two are most likely!
