What is the reason for the squeaking sound of a family car running at high speed

When the car starts cold, there is a terrible sound in the engine, and the car disappears after it runs hot. As long as it is a cold start, there is this strange sound. Look at the timing belt, the clutch of the air conditioner pump head, and whether the clutch is slipping, and the pressure plate is uneven and slipping.

Hello! In this case, it is mainly caused by the loosening of the chassis suspension, and it is recommended that you go to the repair shop to check whether the chassis rubber sleeve is aging and needs to be replaced in time.

Hello, your situation may be caused by the wind noise of the car. Specific learning aptitude checks.

Hello, it is recommended to check whether the abnormal noise of the engine belt is caused by the failure of the sealing strip of the door, and it is recommended to go to the repair station to check it.

Hello, first of all, it is recommended to check your door seals, the pulleys in the engine compartment, and the gearbox

In this case, it is recommended to go to the repair shop in time for inspection and find the abnormal noise for maintenance, so as not to affect the overall safety performance of the vehicle.

What about the sound of the specific **? Whether it is caused by loose parts, it is best to go to the store to check and repair.

Hello, in this case, you can go to the 4S store to test according to the actual car to see if it is caused by this sound.

If there is an abnormal noise at high speed, it depends on the specific type of hit, and it can be relieved by the right medicine.

The main reasons for the buzzing sound of a vehicle while driving are as follows:

1. The tire pressure is too high to cause abnormal noise, and the tire pressure should be adjusted within the standard value range when using the car daily (generally, if the tire pressure is too high, the tire crown will be seriously worn, the shock absorption and cushioning performance of the tire will decrease, and the tire noise will increase significantly.)

2. Abnormal tire wear causes abnormal noise, the crown of the tire is in contact with the ground and rubbing, if the crown is unevenly worn, there will be a buzzing sound.

3. The wheel bearing is damaged and abnormal, and the hub bearing will produce a buzzing sound after wearing, the main reason is that the wheel bearing is worn loose due to long-term use, and the wheel bearing can be protected by avoiding violent impact during daily use, and avoiding wading for a long time can play a protective role in the wheel bearing.

Several aspects of car care are as follows:

1. a belt. In the process of starting the car engine or driving the car, it is found that the belt rings, and the reasons are divided into two types: one is that the belt has not been adjusted for a long time, and it can be adjusted in time after being found. Another reason is that the belt is aging and needs to be replaced with a new one.

2. Air filter.

If the air filter is too dirty or blocked, it will directly lead to increased engine fuel consumption and poor operation. Check the air filter regularly every day, if you find that there is less dust and the blockage is not serious, you can use high-pressure air to blow it from the inside to the outside and continue to use it, and the dirty air filter should be replaced in time.

3. Gasoline filter.

If you find that the oil supply is not smooth, you should check whether the gasoline filter is blocked in time, and replace it in time if it is found to be blocked.

Many cars due to their own structural problems, or their own body weight problems, will make a buzzing sound when driving at high speed, which is the noise of the tires, or it may be a certain problem, if you are more concerned about the safety of the body, you can go to the shop in time for maintenance.

Hello is the tire tire noise sound, motor vehicles driving at high speed, tires and ground friction, and produce abnormal noise. The way to solve this problem is to replace the silent tires and make the whole car sound insulation for the motor vehicle. It can solve the noise from the outside of the car into the car and create a good driving environment.

The tires of the car make abnormal noises.

In most cases, when driving at high speeds, we will hear some slight abnormal noises from the tires of the car, such as the "click" sound. And when the body shakes or shakes, it is the abnormal sound of the tire, which means that there is a problem with the tire. Hurry up and get out of the car to check.

Generally, the screws are loose. If you don't check it in time, it is likely that the tire will automatically disengage. Serious conditions that lead to a car accident.

There was an abnormal noise on the chassis of the car.

The chassis of the car also has many important components underneath, such as gearbox, three-way catalytic converter, fuel tank, etc., which are laid out in the chassis. When we hear the sound of the chassis scraping the ground, it is usually a problem with the three-way catalytic converter.

It may be that there is a lot of carbon deposition that causes abnormal noise. If you don't get out of the car to check, if this is really a problem, it will cause the temperature of the three-way catalytic converter of the car to be too high, and the exhaust gas will not be discharged, resulting in the danger of bursting.

The brakes make a squeak and noise.

I don't know if you feel this way? When we are about to apply the brakes when we drive, we always make a screeching sound, which completely proves that the brake pads have reached the end of their life. Knowledgeable old drivers will quickly replace, and the cost of replacing brake deviations is not high, but the safety hazards are great, it will lead to brake failure, traffic accidents.

The normal life of the brake pads is within 60,000 kilometers, once it exceeds this kilometer, replace it decisively. Of course, in many cases, the abnormal noise disappears quickly, which may be caused by the erosion of the brake pads by rain on rainy days, so you can leave it alone. But there is always an abnormal noise, so it has to be changed.

The engine makes an abnormal noise.

The engine is the core component of the car, it is the heart, once we hear it make a strange sound when we drive at high speed, get out of the car and check it. Because it is generally a big problem, there are many reasons for abnormal engine noise, such as excessive carbon deposit, spark plugs, oil pumps, oil filters, etc.

The car sometimes squeaks while driving, it is recommended to check the steering of the car, the ball head rubber sleeve, and the shock absorbing spring, which may cause these problems.

Noise problems should be checked.

1. There are foreign objects in the tiresWhen we drive, the most abnormal noise we hear is probably from the tires. Of course, tires will also have a sound in normal driving, and we must be familiar with this sound. In this way, once there is an abnormal sound in the driving of the vehicle, we can appear in time.

Second, the abnormal sound of the suspension, in the normal driving process, if there is a problem with the suspension or in the abnormal noise, it is difficult for us to judge the specific cause. So for the driver, for the normal sound of our suspension is also to be mastered.

Third, there is an abnormal sound in the body, in addition to the normal sound of the body. The most abnormal noise is our body. Because many parts can be fixed on the body, no matter if there is a little problem, it may make the body make abnormal noise.

And the abnormal noise of the body is still the most difficult to deal with, because it is difficult for us to see that there is a problem in the stationary state. We can only solve the abnormal sound of the body by reinforcing the visible looseness, and there is no good way.

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.

It is very likely that there is a lack of oil in the shock absorption, and many of them are abnormal noises caused by lubrication. Of course, the possibility of damper damage is not ruled out, and it is safer to drive slowly to the car repair shop for inspection!

This is the abnormal sound of the chassis, which needs to be checked in the maintenance shop to determine that there is a problem with the chassis parts, which is generally caused by damage to the ball joint, lower avoidance, and shock absorber.

It may be a problem with the car's shock absorption and steering system.

When the vehicle makes abnormal noises during driving, it is likely that there is a problem in these places.

Check the shock absorption first.

The system bai shock absorber du spring and the upper and lower wrapping parts are not rubbing.

Scratch marks, tire unloaded, check whether the inner brake disc is true anti-face and other parts after rubbing the scratches, if you are sure that you have not idled the tires with your hands, whether there is a rustling sound (not the sound of rubbing with the brake pads), if there is, you can consider replacing the bearing! These are just for reference because you don't have professional tools.

From the situation you described, it should be a manual transmission car, I don't know whether it appears when the car is cold or after the hot car, if the car is cold, it is likely to be a problem with the belt adjustment wheel; If the hot car appears, there will be more problems, and you have to look at it specifically, I don't know how many kilometers your car has traveled?

It depends on what kind of vehicle it is.

It may be caused by wear of the ball joint on the rear axle.

You can go to the forum of your model to see, maybe it is a common problem, so it is easier to find the reason.

Check the drive belt oil.

It's a problem connecting the engine, so go and see it early...

First check whether there are some plastic products that cause resonance between the car, or check whether the outside door lock hand on the right front and rear doors is loose, which can also cause resonance between travel. Because sometimes it's the little glitches that don't make it easy for us to notice. If there is no problem after checking, then please go to the 4S point and ask someone to check the right front and rear shock absorption, check the chassis screws, check whether the door panel has loose screws, and check whether the inner door panel has buckle breakage.

The reason for the squeaking sound of the belt: the squeaky sound of the belt The squeaking sound of the belt generally means that the friction coefficient on the surface of the belt is greatly reduced, and it has been excessively worn. If you make a noise when the vehicle is loaded, look at one of the sets of transmission belts and you will notice an unusually high level of resistance or elasticity on the belt tensioner or belt tensioners.

Most belt auto tensioners have a set of belt wear length indication signs somewhere along the direction of the chute between their bottom and the tensioner arm. The sign consists of a pointer and two or three markings, which indicate the operating range of the belt tensioner. If the pointer is out of this range, then the belt is probably stretched too long and should be replaced.

In cars where there is no automatic belt tensioner installed, a standard belt elongation gauge is used to measure the middle of the two pulleys. If there is a discrepancy from the standard value, it is better to replace the belt.

The reason for the squeaking sound of the belt: what belts do cars haveThe generator belt is the most important belt in the car, connecting the generator, air conditioning compressor, booster pump, idler pulley, tensioner pulley and crankshaft pulley and so on. Its power source is the crankshaft pulley, which is provided by the rotation of the crankshaft, and then drives the other components to run together.

When a small crack occurs on the surface of the belt in contact with the pulley, it needs to be replaced. If there is a break, it will cause the generator to fail to generate electricity, the booster pump will fail, and the direction will not be moved, which is a very dangerous situation.

The timing belt is connected to the camshaft and camshaft. The crankshaft is connected to the piston, and when the crankshaft rotates, the piston moves up and down; The cam is connected to the throttle valve and controls the opening and closing of the throttle. The piston and the throttle need to work together, and when the piston inhales, the throttle opens; When venting, the throttle closes.

If the timing belt is broken, it will cause problems in the coordination between the piston and the throttle, and even cause the piston to break the throttle, and at the same time cause the piston to be damaged, then it is necessary to overhaul the engine. Therefore, it is best to replace the timing belt regularly according to the service life on the maintenance manual.

Nowadays, many cars should use a chain type of timing belt, the advantage is that its service life is very long, and the cost will not break. According to the national standard, the general vehicle has traveled 60,000 kilometers or two years, and the generator belt and belt accessories need to be replaced, and it is by no means used until it is broken, because once the belt is broken, it will directly affect the safety of driving.

The reasons for the squeaky sound of the car at low speed are: 1. The brake pads are uneven; 2. The position of the high-comic brake pad deviates from the correct position. The solution to the squeaky sound of the car at low speed:

1. Remove the brake pads and grind the edge of the brake pads with an angle grinder; 2. Check the position of the brake pads, if there is any deviation from the adjustment position; 3. Go to the 4S shop for overhaul and replace the brake pads with new ones. The shock absorber of the car may also have abnormal noise when used for a long time, the shock absorber is a wearable part, and it needs to be replaced after a long time of use, and the shock absorber of some cars will leak oil after a long time. The shock absorber is used to suppress the impact from the road surface after the spring absorption, and is widely used in automobiles to accelerate the attenuation of frame and body vibration, so as to improve the driving smoothness of the car.
