Why do the front wheels rattle when driving

What's going on with the abnormal noise of the left front wheel of the car.

1. Possible causes of abnormal noise.

1) 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.

2. Check the 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) Determine the cause of the failure and replace the parts.

If you are sure that it is the front wheel, first remove foreign objects from scratching the spoke hub of the tire rim.

Different types of brakes, according to your own brake type exclusion, disc brake to see whether to rub the disc, V brake to see whether the circle deflection causes the brake pad, other types of brakes and disc V have something in common, refer to the above methods to check and eliminate.

If the abnormal noise is accompanied by a flat tire, check whether the spokes are loose or caused by broken bars, and check whether the rims are cracked.

Quick release or non-quick release, check whether it is loose or whether there is a framed amount according to the corresponding method.

Disassemble the hub to check whether the parts of the hub are broken, check the ball and the ball bowl are in good condition, and check the bearing to be in good condition.

The above is a common situation, there is a very good saying, there can be hundreds of kinds of abnormal noise that may cause the front wheel, if the subject really does not understand, the description of this problem can only go to this extent, then find a car shop, save worry and effort. On the contrary, this question is really insincere and cannot be very good, just like you ask a doctor what is the problem with a stomachache.

The rattling of the right rear wheel of the car, if it is only when passing over a pothole, it should be a problem with the suspension system. The owner can check whether the upper and lower pads of the spring are aging, causing the spring to collide with the metal support and make a sound. Also check the degree of deterioration of the rubber parts at the joints of the various connecting rods of the suspension.

It is also necessary to check whether there is oil seepage after the shock absorption, if there is oil seepage after the shock absorption, it has not played the role of shock absorption. Check whether the rubber sleeve of the screws fixed up and down the shock absorber is loose, if so, it needs to be replaced or found a way to fix it.

Check whether the screws of the chassis, rear axle, tires and other screws are loose, and check and tighten all the screws that may cause abnormal noise. If the dust cover becomes stiff and long, the excess dust cover needs to be cut off due to the sound generated by friction.

The cause of the failure of the shock absorber will make a noise in actual use.

If the shock absorber collides with leaf springs, frames or shafts, the rubber pad is damaged or falls off, the shock absorber dust cylinder is deformed, and the oil is insufficient, the cause should be identified and repaired.

The owner can drive the car to stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell with his hands, if it is not hot enough, it means that there is no resistance inside the shock absorber, and the shock absorber does not work. Appropriate lubricating oil can be added, and then the test is carried out, if the shell is hot, it is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber is out of order.

Mine is also clucking low-speed sound running fast not loud for more than half a month went to the 4s shop and did not find the problem The repairman tightened the screws of the chassis and the rear axle The problem was still not solved Later, I bought the brake pads on the Internet and changed them myself In the process of changing, I found out that the reason was that the tire screws were loose I hope it can help you.

There may be several reasons for this:

1. The clutch sounds;

2. The transmission shaft supports the bearing;

3. Abnormal sound of drive axle;

4. Abnormal noise of the differential;

5. Abnormal tire noise;

6. A certain part of the vehicle loosens the vehicle resonance.

It depends on what the sound and the sound ** can be judged, it is recommended to go to 4S or a repair shop to check.

Check the tires first for problems.

The rattling of the right front wheel is usually caused by three reasons, one is the damage of the shock absorber plane bearing, one is the loose ball head of the lower swing arm, and the other is that the gap between the balance sleeve is too large.

The shock absorber plane bearing of the car is also known as the pressure bearing, which is commonly found in the McPherson suspension of the car, and is based on the spring shock absorber as the load-bearing pillar, which will directly affect the performance of the car after damage, resulting in a poor driving experience of the car.

There is cushioning rubber at the place where the shock absorber is connected to the body, and the rubber products will age and harden after long-term use; When the rubber hardens and is squeezed, it makes a popping sound. In this case, simply replacing the aging rubber on the shock absorber can solve the problem.

When the car passes through a bumpy road section, there is a lot of tire noise and deviation, it means that the damage is more serious, and the suspension may also be damaged, causing the car's steering system to fail.

Here's how to fix it:

If the cushioning rubber is aging, just replace it with a new cushioning rubber. If you change the shock absorber, you need to pay attention to the screws that must be tightened in accordance with the limited sequence and torque when installing, and you must do a new wheel alignment for the car. In this way, the car can avoid mistracking and tire wear.

When replacing accessories, be sure to choose original parts, the reliability and stability of original parts are better.

Sometimes there will be some inexplicable noise during the driving of the car, which is the problem of abnormal noise of the car that everyone will inevitably encounter. But these abnormal noises can not be ignored, because in many cases it is often due to the abnormal movement of the running parts, wear and aging and other reasons to bring abnormal noise, if not timely detection and repair, the light affects the driving mood, and the heavy brings driving safety hazards.

When the vehicle is driving, the wheels are rattling, and the related reasons are as follows.

The first wheel is caused by a problem with the bearing, this phenomenon needs to check the wheel bearing, if there is a problem need to replace the new bearing.

Second, the phenomenon caused by the material of the vehicle's brake pads being too hard needs to be dismantled and polished.

Third, the brake pads are too thin, and the thickness of the brake pads needs to be checked, and if the brake pads are too thin, they need to be replaced with new brake pads.

Your car is injured to the shock absorber, you better go to the 4s or repair shop to lift it up, generally this situation is that the shock absorber is deformed, the suspension may also be injured, the problem will not be very big, it will not affect the safety, that is, the sound is unpleasant, the comfort becomes poor.

If this situation occurs without stepping on the brakes during driving, then it is necessary to consider whether the suspension problem, such as the rubber sleeve of the balance bar, or the ball joint lever, etc., if this sound will appear when the brakes are stepped on, then it is necessary to consider whether the brake pads are thin, or the reason for too much dust in the brake pads.

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 ones are abnormal noises and which ones are imitation abnormal noises. When I went to the repair shop to inspect the vehicles on the abnormal noise bridge tour, only nearly 20% of the cars 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, to use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or to reduce the sound by using a single cylinder fire cut-off to meet the needs of diagnosis. The auscultation site should be kept quiet to minimize human interference.

The abnormal noise of the front wheel of the right gear of the car may be caused by a problem with the braking system, and the cause of the abnormal noise needs to be investigated one by one. It can be caused by severe wear of brake pads, damage to shock absorbers, deformation of the wheel, severe wear of the right front tire, or failure of the propeller shaft.

The brake pads used on automobiles all have wear and tear standards. If the thickness of the brake pads is less than 5 mm, the braking performance of the car will be significantly reduced, and symptoms such as abnormal steering noise will occur in the process of driving a bad car. When this happens, the brake pads must be replaced in a timely manner.

Damage to the right front shock absorber of the car can also cause abnormal noises. In this case, drive to the 4S shop for inspection, and you should use professional repair tools for repair.

In addition, after the deformation of the wheel hub of the car, the car will emit abnormal noise during driving, which will not only affect the comfort of the car, but also affect the safety of the car. In this case, the wheels should be replaced with new ones in a timely manner.

During use, too many or too few car tires will wear out. If you often drive on roads with poor road conditions, it is recommended that car owners regularly check the tires of the car to avoid affecting the normal use of the car.

The abnormal sound of the right front wheel of the car may be a problem with the braking system, and the cause of the abnormal noise needs to be investigated one by one. It can be caused by severe brake pad wear, damaged shock absorbers, wheel deformation, severe right front tire wear, or driveshaft failure.

The brake pads used in automobiles have wear standards. If the thickness of the brake pads is less than 5mm, the braking performance of the car will be significantly reduced, and there will be abnormal turning noise and other symptoms during the driving of the car. When this happens, the brake pads must be replaced in time.

Damage to the shock absorber on the right front wheel of the car can also produce abnormal noises. In this case, you should drive the car to the 4S shop for inspection, and use professional maintenance tools for maintenance.

In addition, after the wheel hub of the car is deformed, the car will make abnormal noises during driving, which will not only affect the comfort of the car, but also affect the safety of the car. In this case, the wheel hub should be replaced in a timely manner.

Automobile tires will wear out if they are too much or too little in the process of use. If you often drive on roads with poor road conditions, it is recommended that car owners regularly check the tires of their cars so as not to affect the normal use of their cars.
