JAC Ruifeng M5 middle door makes abnormal noise

1. Abnormal noise from the car body

Abnormal noise from the car body is the most common. It is usually caused by insufficient stiffness of the car body. Long-term intense driving or a lot of walking on bumpy roads will cause slight deformation of the steel frame of the car body. , the most direct impact is abnormal impact or friction between the door and the car, or abnormal friction in some welding or screw parts, which may also cause abnormal noise; and some cars have larger wind noise, which to a certain extent is different from the car. related to the shape.

Solution:

These abnormal noises are not terrible and will not have a great impact on the overall performance of the vehicle, but they are troublesome to deal with and difficult to cure. They can only be caused by abnormal conditions. Add rubber pads or sponges to friction or impact areas.

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 loosely installed decorative panels and the co-pilot glove box. Loosening, seat belt buckle impact, etc.

Solution:

Automatically reset it or fill it with soft objects.

3. Abnormal brake noise

If there is a "squeaking" sound when applying the brakes, it is most likely caused by excessive wear of the brake pads, resulting in undue gaps. Of course, improper use or deformation of the material of the brake disc, and unqualified hardness, porosity, friction characteristics and compression characteristics of the brake pads may cause abnormal noise.

Generally speaking, the life of the front brake pads is 30,000 kilometers and the life of the rear brake pads is 120,000 kilometers.

Solution:

Abnormal brake noise can usually be solved by replacing the brake pads. If the brake disc is damaged, it also needs to be replaced. When replacing, pay attention to the model and other issues, otherwise the mismatch will still persist. There will be abnormal noise.

4. Suspension abnormal noise

The suspension system continues to operate during driving, and the rubber bushings between the shock absorbers and each connecting rod will inevitably wear out. When the bushing ages or falls off, 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 shop to have a specialized master replace the parts. If it occurs, it must be solved as soon as possible. It is best to strengthen inspections during daily maintenance to prevent abnormal noise from occurring.

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, road surface conditions, etc. Factors produce various noises of different strengths and weaknesses. When there is a low "pop" sound, it is mostly due to tire tread deformation, bagging, serious wear or insufficient air pressure. If there is a "click" sound, it may be that the tread is mixed with small stones or nails.

If the wheels make a sound of metal collision and friction while driving, it is likely that the shock absorbers and bearings are damaged. Car owners should pay attention 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 problems need to be brought to the attention of the car owner and asked to be dealt with by professionals.

6. Abnormal noise from the steering wheel

Abnormal noise will be detected when the steering wheel is turned left and right. When an abnormal noise occurs halfway through the direction, it can be basically judged as abnormal noise from the steering gear. If It is difficult to tell the source of the abnormal noise after the steering wheel is turned. The most common answer obtained when going to a 4S store for testing is the friction of the rubber sleeve of the steering rod ball head.

In addition, abnormal noise can also be caused by oil leakage from the dust jacket of the steering gear, insufficient tightness of the power-assisted belt or aging.

Solution:

The steering tie rod ball head is aging 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 is squeaking or whistling, it is usually caused by the belt slipping. If it is the sound of air leakage, it may be caused by 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, it may generally 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 is in use while the car is driving There is a "rustling" sound inside, and there is a whistling sound when shifting gears. This may be caused by the gearbox bearings or gears being worn or bearing spots.

If the gearbox makes abnormal noise when speeding up and shifting gears, it may be that the gearbox oil contains metal powder, indicating excessive wear of the gearbox brake belt, clutch and other components.

Solution:

The gearbox is a precision equipment, so no matter what abnormal noise occurs, it needs to be repaired in time.
