Anonymous users2024-02-12First 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.

Anonymous users2024-02-11Featured Q&A: What is the reason for the loud sound of the car.
1.The engine overheated and caused the engine to lose power. If the engine is so active for so long that the surface overheats, the cooling system will strike.
The first thing to do at this time is to check the cooling system, if there is a problem with the air conditioning system, it may lead to a blockage in the exhaust gas, because there is a high chance that the vacuum pipe will break. At this time, steam or hot air will come out of the engine, which will make some "wow" sound. So as soon as you hear this sound, it is time to check if there is a problem with the cooling unit.
Of course, if the sound is made in the place of the exhaust pipe, it proves that there is a problem with the exhaust pipe first, and it is necessary to check the exhaust pipe first.
2.There is a problem with the inside of the engine, such as a clogged valve. In the process of driving, sometimes we don't see anything wrong with the appearance, but we find that the throttle is not strong when refueling.
It could also be a problem with the engine. Because when the throttle is added, the engine speed is actually increased, but the speed is not raised, which indicates that there is a problem with the inside of the engine. At this time, it is also necessary to look at the cooling system to see if the coolant is normal.
Then check the oil pressure gauge to see if it's because of the oil pressure, or if it's an ignition problem. There is also the problem of clogged internal valves and so on. If there is a loud noise when accelerating or decelerating, then you have to look at the generator shaft, or even the water pump, power steering pump, etc.

Anonymous users2024-02-10There are two situations, the first may be that your car is still in the run-in period, and the engine control template has not yet carried out the ignition time to the closest value of deflagration, that is, the ignition time of your engine has been delayed, so as to cause engine deflagration. The second situation is that the oil pressure of the engine is so low that the engine shivers.

Anonymous users2024-02-09If the problem is locked in the tire, the 4-wheel alignment will indeed affect the tire noise, but before the tire eccentricity problem occurs, the deviation of the 4-wheel alignment will not affect the very large tire noise, and the tire noise is still the following: tire pressure, tire width, tire material, tire tread shape, and the width of the tire tread groove.

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.
Let's start with axle bearings.

Knee sounds are divided into physiological and pathological sounds. Physiological sound is mainly when most adults straighten and bend their knees, they will hear a pop pop, and then there are no uncomfortable symptoms, and it will not cause pain or weakness especially in the knees. There is also a pathological snap, the most common is called synovial fold syndrome, that is, the knee has been injured, causing the synovium inside to scarring, so when the knee is moved, it causes the knee to pop and rub; Then there is also a kind of bounce caused by the presence of loose bodies in the joint, that is, some bone spurs fall off, and then cause the bone spurs to slide in the joint caused by the snap, which is often combined with pain; Another more common type is meniscus injury, which can be caused by trauma, and moving loose bodies in the joint can also cause the knee to snap, and this is often combined with pain, the latter two can be repaired by minimally invasive knee arthroscopic surgery. Of course, there are some patients who have repeated popping sounds, and it is also necessary to rule out whether there are extra-interjunctical factors, so this requires a doctor to conduct a physical examination and give him a touch to judge, and there is generally no major problem after excluding these factors.
The brain buzzing you are talking about may be brain ringing, and there are many factors that cause brain ringing, and you have to go to the hospital for examination and diagnosis.
Reason: The filter screen is too dirty, and the air inlet is blocked, resulting in a noisy air conditioner inside; The inner cover is not tightly covered, resulting in vibration and sound when the air conditioner is working; The sudden change in temperature causes the plastic shell and the internal plastic parts to expand and contract, resulting in sound. Workaround: >>>More
The cause of brain buzzing during sleep may be neurogenic encephalopathy, which may be caused by arteriosclerosis, cerebral insufficiency, high blood pressure, hyperlipidemia, cervical spondylosis, etc. It is mainly caused by long-term stress, insufficient nutrition, or poor rest. You can go to the nearest regular hospital to check blood pressure, blood lipids and blood sugar, cervical spine CT, and find out the cause before symptomatic**. >>>More
