1. Abnormal noise from the car body
Abnormal noise from the car body is the most common. It is usually caused by insufficient rigidity of the car body or long-term intense driving. walking on bumpy roads will cause slight deformation of the car body steel frame, the most direct impact is abnormal impact or friction between the door and the car, or abnormal friction in some welding parts or of screws, which may also cause abnormal noise. ; and some cars have more wind noise, which is different from the shape-related car to a certain extent.
Solution:
These abnormal noises aren't terrible and won't have a big impact on the vehicle's overall performance, but they are annoying to deal with and difficult to cure. can only be caused by abnormal conditions. Add stampsrubber or sponges to areas of friction or impact.
2. Abnormal noises in the car
Abnormal noises in the car are the most common, and there are many places where abnormal noises occur, such as improperly installed decorative panels and the glove box. of the driver Loosening, impact of seat belt buckle, etc.
Solution:
Reset it automatically or fill it with soft objects.
3. Abnormal brake noise
If there is a “squealing” sound when applying the brakes, it is most likely caused by excessive wear of the brake pads, resulting in excessive gaps. Of course, improper use or deformation of the brake disc material, as well as unqualified hardness, porosity, friction characteristics and compression characteristics of the brake pads may cause abnormal noise.
Generally speaking, the duration ofThe life of the front brake pads is 30,000 kilometers and that of the rear brake pads is 120,000 kilometers.
Solution:
Abnormal brake noise can usually be resolved by replacing the brake pads. If the brake disc is damaged, it must also be replaced. When replacing, be careful. Model and other issues, otherwise the disparity will always persist. There will be an abnormal noise.
4. Abnormal suspension noise
The suspension system continues to operate while driving and the rubber bushings between the shock absorbers and each connecting rod inevitably wear out as the bushing ages or. falls, there will be abnormal metal impact sounds. If the shock absorber is broken, there will be a "dong dong" or "click" sound on bumpy roads.
Solution:
Generally, abnormal suspension noise cannot be solved by yourself. You must go to a repair workshoprepair or a 4S workshop for a specialized master to replace the parts. If this occurs, it must be resolved as quickly as possible. It is best to strengthen inspections during daily maintenance to avoid the occurrence of abnormal noises.
5. Abnormal noise from tires
Abnormal noise caused by tires is generally tire noise. The noise generated will also depend on the car's driving speed, tire type, tire pressure and road surface. conditions, etc. Factors produce various noises of different strengths and weaknesses. When there is a faint “pop” noise, it is mainly due to tire tread deformation, bagging, heavy wear, or insufficient air pressure. If there is a “clicking” sound, the tread may be mixed with small stones or nails. .
If the wheels make a colliding noisesion and metal friction while driving, it is likely that the shock absorbers and bearings will be damaged. Car owners should be careful when encountering these problems, even just driving nails can be dangerous.
Solution:
It was found that the tread was mixed with small stones.Wait, you can clean it yourself. Other issues should be brought to the attention of the car owner and handled by professionals.
6. Abnormal noise from steering wheel
Abnormal noise will be detected when the steering wheel is turned left and right. When an abnormal noise occurs halfway, it may be. essentially considered an abnormal noise coming from the steering gear. If it is difficult to determine the source of the abnormal noise after the steering wheel is rotated, the most common answer obtained by going to a 4S store for testingis the friction of the rubber sleeve of the steering wheel. the steering rod ball joint.
In addition, abnormal noises may also be caused by oil leakage from the steering gear cover, insufficient tightening of the power assist belt, or aging.
Solution:
The tie rod ball joint is getting old and the steering gear has problems and needs to be replaced in time.
7. Abnormal noises in the engine compartment
The situation of abnormal noises in the engine compartment is complicated and requires careful investigation.
If the belt squeaks or whistles, it is usually due to belt slippage. If it is an air leak noise, it may be caused by a blockage or breakage in the exhaust system or vacuum tubes; If there is friction and abnormal noise from external metal parts when the engine is running, this can usually be caused bys damage to the generator, water pump, etc.
Solution:
Find a professional to repair it as soon as possible
8 Abnormal noise in the gearbox
If the gearbox gear is broken. is moving while the car is driving If there is a "rustling" sound inside and a whistling sound when changing gears, this may be caused by worn gearbox bearings or gears or by rolling points.
If the gearbox makes an abnormal noise when accelerating and changing gears, the gearbox oil may contain metal powder, indicating excessive gear wear. the brake belt of the gearbox, clutch and other components.
Solution:
The gearbox is precision equipment, so no matter what abnormal noise occurs, it should be repaired in time.
