What s going on with the abnormal sound of the front wheels of the car, what is the abnormal sound o

If it is a new car, the new car disc and disc are in a run-in state, which leads to a variety of reasons for abnormal brake noise, rust in water, stones stuck in the middle of the disc and disc, and large metal particles in the brake pad. It doesn't matter as long as it doesn't affect the performance of the brakes.

Check the bearings, shock absorption.

The reasons for the abnormal noise of the front wheels of the car are: 1. The front shock absorber is faulty; 2. The front-wheel drive half shaft is loose; 3. Loose chassis screws and rubber components; 4. The ball joints and bearings are loose; 5. Cracking of the wheel bearing; 6. The wheel hub lacks grease; 7. The steering tie rod is bent. The inspection steps for abnormal noise of the front wheels of the car are:

1. Use the lifter to lift the vehicle; 2. Check whether the screws and rubber components at the front end of the chassis are loose; 3. Check whether the shock absorber is good before disassembly; 4. Disassemble the front wheel and check the bearing; 5. Check whether the front wheel drive half shaft is loose; 6. Judge the cause of the failure and replace the parts.

This is likely to be due to the poor fluidity of the shock absorber oil in the shock absorber at low temperatures, resulting in excessive resistance of the damper during movement, which leads to the occurrence of this phenomenon, and it is also possible that the dry grinding of rubber parts such as balance bar lifting lugs and arm rubber sleeves will also cause abnormal noise after losing their elasticity at low temperatures.

Possible causes of squeak and squeak:

Front shock absorber failure.

2.The front-wheel drive half-shaft is loose.

3.The chassis screws and rubber components are loose, and the ball joints and bearings are loose.

Inspection steps: 1. Lift the vehicle with a lifter.

2. Check whether the screws and rubber components at the front end of the chassis are loose;

3. Disassemble the front shock absorber and check whether the shock absorber is good.

4. Disassemble the front wheel and check the front wheel bearing.

5. Check whether the front wheel drive half shaft is loose;

6. Finally, the cause of the fault is judged and the parts are replaced.

Abnormal wheel noise: Abnormal wheel noise is likely to be caused by untimely maintenance of the vehicle, or often driving on bad roads, resulting in uneven wear of tires, and serious wear of tire bearings.

It is difficult for ordinary car owners to distinguish which are fault abnormal noises and which are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Models equipped with turbocharged engines are different; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.

If there is an abnormal sound on the front wheel of the car, it should be investigated from the following aspects: 1. The abnormal noise of the door, the structure of the door is relatively simple, and it is necessary to see if it is because the screws are not tightened. 2. The abnormal sound of the skylight is very normal, and the guide rail inside the skylight will fall with small stones or dust, and if the sealing is not strict for a long time, it will produce abnormal noise.

3. The abnormal sound of the center console, the abnormal sound of the center console is generally related to the overall workmanship and materials of the car. It is necessary to consider whether the center console has been removed before the car and whether the navigation cable has been installed. 4. Abnormal noise ** in the chassis, or ** outside the car, in this case, it is recommended to go to the 4S store to check.

What is the reason for the abnormal noise in the front wheels of the car.

There are many reasons for this:1. It is the vehicle's dismantling braking system that causes friction between the brake caliper and the brake pads.

2.The front bearing of the vehicle failed. 3.

There is a problem with the front driveshaft of the vehicle. This kind of abnormal noise mainly occurs when the vehicle is driving.

What is the effect of the abnormal noise of the front wheels of the car.

It has a great impact on the overall driving safety of the vehicle. In the process of driving, it is easy to have potential safety hazards and cause accidents. If there is an abnormality in the front wheels of the vehicle, stop the vehicle when it is safe to do so.

It is necessary to preliminarily determine the abnormal noise**, or contact the repair shop for a detailed inspection, before continuing to use the vehicle.

The abnormal noise of the front wheels of the vehicle must be repaired.

It had to be repaired. It's not just the front wheels of the vehicle that are abnormal, but any part of the vehicle. The vehicle should be maintained regularly, and the problem should be repaired in time, so as to avoid the occurrence of problems. In this way, you can drive safely and ensure the safety of the people in the car.

Millions of car purchase subsidies are poor.
