When the car is driving, it feels like the wheels are making abnormal noises

How does it sound? Click, buzz or squeak? Click-check the hub screws, buzz check the bearings, and squeak check the brake pads.

Summary: Hello, glad you asked.

When the car first starts, the wheel hub squeaks intermittently, and it is fine for a while, and there may be three reasons:

1. There is a foreign object between the brake disc and the brake pad; The brake disparator pump is broken, and the caliper cannot be separated from the brake disc; Excessive wear of brake pads causes grinding iron and needs to be replaced in time.

2 The most common reason is that the friction pads are worn thin, and the brake pads will automatically alarm, and the wheels need to be removed for inspection. If the brake pads are not thin, look at the wheels and the transmission half shaft near the wheels to see if there is something like iron wire entangled.

3. If the vehicle is not regularly maintained, it may cause problems such as wear of the movable pin of the brake caliper and falling off of the spring blade. Poor caliper reset will cause the disc to rub against the disc for a long time to make abnormal noise, and it is also necessary to check whether the brake disc is grooved, because local friction will cause abnormal noise. Hope mine can help you.

You're welcome, I hope to give a thumbs up thank you.

1. Fault 1: Low-speed driving emits a rhythmic humming sound, and the abnormal noise of high-speed driving is weakened.

Reason: The four-wheel alignment of the vehicle is inaccurate, and the long-distance driving has great wear on the tires, and the tires form eccentric wear and make abnormal noises.

Solution: Touch the pattern of the tire with your hands, if you can feel the unevenness of the inner or outer pattern, it must be the cause of the abnormal noise. Be sure to do a four-wheel alignment first and then change the tires.

2. Fault 2: The abnormal sound of low-speed driving is not obvious, and the reason for the uniform humming sound of high-speed driving: this phenomenon occurs when a wheel bearing of the vehicle is damaged.

Long-distance driving has high requirements for the bearings of the wheels, and the bearings with poor quality or have been used for a long time will be damaged due to fatigue and make abnormal noises under long-term high-speed operation.

Solution: Go to the service station to judge the abnormal noise part, determine which wheel is the problem, and replace it.

Well, I think it's the sound of the brake pad box brake disc rubbing, if it's the original brake pad. You don't have to think about it, if it is a brake pad from the analogue, it is recommended to replace the original parts. How to tell if it is a brake pad rubbing sound:

When the noise appears, tap the brakes, if the noise goes away, you can confirm, and if the noise doesn't go away, check elsewhere.

As long as there is a little bump in the road, this sound is particularly annoying The abnormal sound of the rear wheels, most of which is the abnormal sound produced by the brake part. 1. If the car has been hearing the sound of the rear wheel grunting and other sounds when driving, gently step on the brake, the sound disappears, and there is an abnormal sound when the brake is released, which is generally the imbalance of the brake disc and the jumping during driving, resulting in the abnormal sound of the rear wheel. In this case, re-fastening the brake disc or replacing the brake disc can solve the problem.

2. If you hear the abnormal sound of the brake disc and find that there is a groove caused by friction on the brake disc, this is the uneven side of the friction plate, resulting in abnormal friction sound. In this case, you can polish the friction surface flat (when the friction plate is still relatively thick), or replace the friction plate, and check the brake return mechanism to make the return in place, which can eliminate the friction noise. 3. If you hear the abnormal sound of the brake disc and set up the wheel, you find that the wheel makes an abnormal sound, and the wheel is not rolling smoothly or shaky, it may be that the handbrake cable is too tight, or the handbrake return mechanism is faulty, resulting in a certain braking effect when the handbrake disc is driving, so that the car is not smooth.

4. If there is an abnormal noise when driving, the faster the speed, the louder the sound. In this case, it may be that the rear wheel bearing is broken. 5. If the wheel rotates around, you will hear an abnormal sound, most of which is a tire clamping stones or hard things, or a fixed part touching the rotating parts on the wheel, causing a regular abnormal sound.

When encountering fixed parts and rotating parts, you can check whether the tire rotates smoothly, whether the brake disc jumps, and whether the gap between the brake pad and the friction pad is appropriate after returning. 6. If the wheel is abnormal and accompanied by the phenomenon of gnawing the tire, it may be that the tire fixing screw is loose, or the wheel hub is worn loose for a long time, and this kind of situation @2019

The reasons for the abnormal noise of automobile tires are as follows: 1. The rhythmic humming noise of low-speed driving is weakened by the abnormal noise of high-speed driving. Cause of failure:

The four-wheel alignment of the vehicle is inaccurate, and long-distance driving has a large tire wear, and the tire is biased and abrasive, making an abnormal sound. Fault solving: If you can feel the unevenness of the inner or outer pattern of the tire, it must be the cause of the abnormal noise.

Be sure to do a four-wheel alignment first and then change the tires. 2. The abnormal sound of low-speed driving is not obvious, and the high-speed driving emits a uniform humming sound. Cause of failure:

This phenomenon occurs when one of the wheel bearings of a vehicle is damaged. Long-distance driving has high requirements for the bearings of the wheels, and the bearings with poor quality or have been used for a long time will be damaged due to fatigue and make abnormal noises under long-term high-speed operation. Troubleshooting:

Go to the service station to determine which wheel is the problem of abnormal noise and replace it. 3. The road pattern clamps the stones or pierces the nails, glass and other sundries.

The vibrations that exist in the various mechanisms of the car when it is working.

On the issue of abnormal noise, it is difficult for ordinary car owners to distinguish which ones are fault abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; 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 they lack their own understanding of mechanical knowledge, so they can 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 sounds, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is smaller than that of the pin collapse stove, 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 driving 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.

Causes of abnormalities in car wheels: gravel embedded in the tread pattern or damage to shock absorber bearings, etc. The higher the frequency of this periodic sound, the faster the speed of the vehicle. In this case, first check whether the tire screws are tightened to eliminate abnormal noise.

1.Rhythmic, high-pitched sounds. This can be a friction sound caused by too little clearance between the brake shoe and the brake disc.

2. Continuous sharp sound, it may be that the bearing is broken. 3.Constant dull noise can be a problem with the driveshaft.

4.You can also know if there is a change in the sound during the hanger and traction. If there is, it is most likely a propeller shaft.

First of all, check if the tire screws are tightened to eliminate abnormal noise. When the hub screws are loose, the wheels will make a slight knocking sound when the brakes are lightly applied downhill. If the rear wheel screws are loose, the noise of the wheels will be amplified through the trunk and may be mistaken for something placed in the trunk.

When the hub screws are severely loose, the wheels will swing back and forth when walking, and a noticeable clicking sound will be heard at low speeds. At this time, immediately stop and check the hub screws. If the sound of the tires is rhythmic, if the speed is fast and the frequency is high, judge the reason according to the sound:

If it is low, it is mostly due to the deformation of the tread of the wheel, bagging, serious wear or insufficient air pressure; If it is a "click" sound, it may be that the tread is mixed with small stones; If the tires are honking, the body is obviously shaking or even running out of direction, needless to say that the tires must have burst, get out of the car and change the tires. If there is metal collision noise inside the tire while driving, it may be caused by damage to the shock absorber and bearing of the anti-eliminator, and the owner should go to a professional auto repair shop or 4S shop for repair.
