1, the body has abnormal sound
Symptoms: There are always some abnormal sounds in a certain part of the car when driving the accelerator or brake. The sound is not loud, and it does not affect the normal driving, but there is always a little worry about what went wrong.
Solution: First check whether there are objects that are not fixed, easy to roll and make sounds in the trunk or rear seat of the car, to eliminate the noise that some items are not fixed.
If you find that the door and window parts are rubbed to cause abnormal noise, you can stick the rubber strip on the door and window or rubber in the friction part, which may reduce or eliminate the abnormal sound, but the result is only the palliative. If the above problems are not found, you must go to the regular repair shop for inspection and troubleshooting. 
2, the engine has abnormal sound
Symptoms: There is a greater chance of abnormal noise in the engine compartment. Most people also judge the abnormal sound of the engine compartment based on the sound source. It is usually a metal squeak or a whistling noise.
Solution: The abnormal noise of the engine indicates that the technical status of an engine has changed. Mainly due to some parts worn or even assembled or improperly adjusted. Some abnormal sounds can predict that the engine will be accidentally damaged. Therefore, when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.
Need to be reminded that if it is abnormal noise inside the engine, most of the owners can not solve it by themselves, and send it to the factory for repair.
3, the gearbox has abnormal sound
Symptoms: If the car has a "sand" sound inside the gearbox while driving, and there is no brake or throttle, there will be a whistling sound when shifting.
Solution: There are many transmission parts, and the cause of the noise is also complicated. When analyzing and judging, it should be noted whether it is related to a specific speed. For example, some planetary teeth are louder at around 50Km/h. Whether it is related to certain gears, it is very important to judge the transmission fault. If a certain gear is sounded, it must be related to the components that affect the transmission. If all the gears are ringing, it is often the fault of the common gear shaft or the lack of the transmission. oil. Whether it is related to a specific action, such as adding, downshifting, starting, rapid acceleration, rapid deceleration, turning, etc. are effective means for judging abnormal sound, wherein the transformation speed and the direction of transformation are particularly important for determining the rear axle failure.
If the abnormal noise of the transmission is obvious, it is recommended to send a professional repair shop to check the faulty parts and then replace them. 
4, the tire has abnormal sound
Symptoms: The tires make a rhythm, and the faster the speed, the higher the frequency.
Solution: First check if the tire screws are tightened to eliminate abnormal noise. When the hub screw is loose, tap the brake when going downhill, the wheel will make a slight humming sound. If the rear wheel screw is loose, the sound of the wheel will be amplified through the trunk and may be mistaken for the back box. Something sent out. When the hub screw is loose, the wheel will Swing in the middle of walking, and a relatively loud hum will be heard at low speed. At this time, stop the wheel screw immediately.
If the tire sound is rhythmic and the speed is high, the sound is judged according to the sound: if it is a low "beep" sound, most of the tire tread deformation, bagging, serious wear or insufficient air pressure; "å—’å—’" sound, it may be that the tread is mixed with pebbles; if the tires are screaming, and the body is obviously shaking or even moving in the direction, it goes without saying that the tires are blasting, get off the tires; if you are driving During the process, the sound of metal collision inside the tire may be caused by damage to the shock absorber and the bearing. The owners should go to a professional auto repair shop or 4S shop for repair.
5, hanging abnormal sound
Symptoms: When passing through a speed bump or uneven road surface, the suspension noise is very serious, and there is an abnormal sound on the flat road.
Solution: When you encounter bumps near the four wheels, you will make a "beep" or "beep" sound. Most of them are caused by shock absorber problems or loose parts. Please check with regular repair shop.
6, the engine guard plate has abnormal noise symptoms: the engine guard plate has been installed for some time, but after going out to run some suburban road conditions, come back and there will be a strange sound at the guard plate.
Solution: The screw will often shift in the car that is constantly moving. If you often hear the abnormal sound like the position of the air intake grille, except the grille is really loose, then the owner still needs to Check if the engine guard plate screws are loose, or the engine guard plate and the film are loose, causing abnormal noise. In addition to tightening the screws, you should also put some cardboard items in the abnormal sound area to easily eliminate the abnormal noise. 
7, the brakes have abnormal noise symptoms: the vehicle emits relatively loud noise and abnormal noise when the brakes are applied.
Solution: Brake friction plate is one of the most important parts in the brake system. Under normal circumstances, the life of the front brake friction plate is 30,000 km, and the service life of the rear brake friction plate is 120,000 km. If a “beep, bang†sound is heard when the brake is applied, most of it is a warning sound from the wear indicator of the brake lining, which indicates that the brake lining exceeds the limit of use. When this happens, the owners should go to the car dealership for repair as soon as possible, otherwise the brake friction plate will be exhausted, resulting in damage to the brake components, brake braking and accidents.
8. The shock absorber has abnormal sound
Solution:
1). See if the shock absorber leaks oil. Look directly at the shock absorber housing or dust jacket without rain or car wash. You can see it at a glance.
2). There is listening. At low speeds, there is a squeaking sound when the wheel passes through the raised portion of the road surface or when there is a slight vibration. The abnormal noise of the shock absorber is different from other chassis abnormal sounds, which is very dull. There is also a noticeable shock on the steering wheel of the front shock absorber. Finding an experienced driver can make a very accurate judgment of the suspension.
3). There is also the upper part of the suspension part of each wheel by hand, such as pressing the front and rear fenders. The faulty shock absorber is pressed hard. This is the symptom of the shock absorber leaking to the later stage. This must be judged by an experienced service technician.
4). The shock absorber has only been replaced and there is no way to repair it.
9. There is abnormal noise when playing the steering wheel
Symptom description:
The abnormal sound in the direction of the original position may be caused by a problem with the rubber parts such as the balance bar lifting eye and the arm rubber sleeve.
There are three reasons for running an abnormal sound at high speed:
First, this kind of sound may be tire noise. Each tire will have tire noise, but the time and sound size will be different, which will not affect the normal use. Second, the front and rear wheels will be wrong, resulting in tire tread. Wavy wear will also produce such an abnormal sound; third is caused by the wear of the wheel bearings.
Solution:
1) Check the rubber parts such as the balance bar lifting lug and the arm rubber sleeve
2) Check the tires to confirm that it is not tire noise.
3) Check the front beam of the front and rear wheels
4), the last check, whether the wheel bearing wear is serious, if it is serious, replace the left and right bearings.
10. There is abnormal noise in the stepping clutch. The separation bearing is worn or stuck; the separation lever pin and the pin hole are loose due to wear; the drive pin and the pin hole are loose due to wear.
Solution:
1). Continuously stepping on and releasing the clutch pedal, the clutch will sound when engaged or disengaged, and can be judged as the rivet of the separation lever pin hole and the support pin worn loose or the driven disc assembly according to the severity of the sound. Loose, damper failure and other reasons.
2). After stepping on and relaxing the clutch pedal, press the accelerator pedal again. If there is a intermittent impact sound, the return bearing spring will be broken or broken.
3). Two-plate clutch, when the pedal is stepped on the bottom, the sound of “click, click†is caused by the excessive clearance between the intermediate platen hole and the drive pin.
