Hello, for this phenomenon, I suggest you check if the belt tensioner is aging, and also to check if there is a noise coming from the generator compressor. If there is no problem with the above, it means there is noise in the engine. , caused by excessive engine wear. This is what I recommend you try a full synthetic motor oil, which can reduce wear and noise, and also protect the life of the engine. I wish you good use of the car. you have any car questions, ask an auto guru. Professional technicians at 4S stores can solve the problem within 10 minutes.
1. Abnormal noise from the car body
Abnormal noise from the car body is the most common. It is usually caused by insufficient body rigidity and long-term intense driving. or a lot of walking on roadsbumpy roads, which will cause damage to the steel body of the car. If the frame is slightly deformed, the most direct impact is abnormal impact or friction between the door and the car, or abnormal friction in some. welded or screwed parts, which can also cause abnormal noise; and some cars have relatively large wind noise, which may occur to a certain extent. This is due to the shape of the car.
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 rubber pads 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 occursmells, such as incorrectly installed decorative panels and co-driver's glove box Loosening, seat belt buckle impact, 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 lifespan of front brake pads is 30,000 kilometers and that of rear brake pads is 120,000 kilometers.
Solution:
Abnormal brake noise can usually be resolved by replacing the padss brake. 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 need to go to a repair shop or 4S workshop to have a specialized master replace the parts. If this occurs, it must be resolved as quickly as possible. It is best to strengthen inspections during daily maintenance to avoidter the appearance 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 weak "pop" noise, it is mainly caused by tire tread deformation, bagging, heavy wear or insufficient air pressure. If it is "clicking", the tread may be mixed with small stones or nails.
If the wheels make a collision and metallic friction noise while driving, it is likely that the shock absorbers and bearings are damaged. Car owners should be careful when encountering these problems, even just pushing keysou can be dangerous.
Solution:
If you find that the tread is mixed with small stones, 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. While it is difficult to determine the source of the abnormal noise after the steering wheel is rotated, the most common response obtained when going to a 4S shop for testing is friction of the steering wheel rubber sleeve. the steering rod ball joint.
In addition, abnormal noises may also be caused by oil leakage from the steering gear jacket, insufficient tightening of the assist belt.e electrical 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 by 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 SThere is a 'rustling' noise inside and a whistling sound when changing gears, this may be caused by worn gearbox bearings or gears or bearing 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.
I hope to adopt him!
