How to solve the abnormal sound of wire movement

Symptom description: There is a high possibility of abnormal noise in the engine compartment. Most people also judge the abnormal noise in the engine compartment according to the sound source, usually the harsh noise of metal or the noise of the wind whistling.

Solution: The abnormal sound of the engine indicates that the technical state of a certain mechanism of the engine has changed. The main reason is that some parts are worn or even improperly adjusted. Some abnormal sounds can indicate that the engine may be accidentally damaged, so when the engine has abnormal sounds, it should be repaired in time to prevent the fault from expanding.

Need to be reminded that if the engine is abnormal, most owners can't solve it by themselves, so it's best to send it to the factory for maintenance.

2. The gearbox has abnormal sound.

Symptoms: If there is a "rustling" sound inside the gearbox when the car is driving, but it disappears after stepping on the clutch or accelerator, there will be a whistle when shifting gears.

Solution: There are many transmission parts, and the causes of noise are complicated. When analyzing and judging, we should pay attention to whether it is related to a specific speed. For example, the noise of some planetary gears is obvious around 50 km/h, and whether it is related to some gears is very important for judging the fault of the transmission. If a gear rings, it must be related to the parts that affect the transmission of that gear. If all gears ring, it is often the fault of the normally meshed gear shaft or the lack of oil in the transmission. Whether it is related to specific actions, such as upshifting, downshifting, starting, sudden acceleration, sudden deceleration, turning, etc. It is an effective means to judge abnormal sound, and changing the speed and direction is particularly important to judge the rear axle fault.

If the abnormal sound of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts and then replace them.
