What is the reason for hearing a rattling sound while the car is moving?

If you hear the abnormal sound of "Zizi" in the process of driving, and this is the abnormal sound caused by the problem of the engine belt, because the abnormal sound of "Zizi" is mostly the aging of each belt group of the engine, or the belt is too loose caused by the problem of the tensioner, the friction abnormal sound, belt slippage, etc., if there is a similar "Zizi" abnormal sound, then look for the major belt groups and tensioners inside the engine, such as engine timing belt, generator belt, circulating water pump belt, air conditioning belt, power pump belt, etc. The problem that causes this abnormal noise is the abnormal sound of the engine belt, which is caused by the smooth grinding surface of the joint surface of the belt and the pulley. It usually occurs when the engine speed changes rapidly, and sometimes the belt rings when the load of the attachment driven by the belt increases.

How to solve the problem of abnormal noise of engine belt.

1. Check whether the accessories driven by the belt are damaged, stuck, loose or the power of the accessories has increased.

2. Replace the belt, or use 100 gauze to polish the joint surface of the pulley and the belt (light grinding is fine).

3. The temporary solution can be to drop 1 2 drops of oil on the joint surface of the belt and the pulley (it will not affect the belt slippage).

If it is the generator belt that rings and the headlights are more obvious, you have to take off the generator belt, turn the motor pulley to see if the generator rotates smoothly, if the generator is normal, you can check whether the battery is not stored power, because the battery storage is not good will increase the load of the generator.

It may be that the belt is loose and slippery, check if the belt is cracked or hardened. Then check the chassis screws and so on, your description is relatively broad, depending on the specific situation.

Hello: According to your description, the possibility of failure is that the shock absorber is already very high, and it is recommended to replace the shock absorber.

Hope the above helps, thanks!

One possibility bai

It is due to the phenomenon of poor return of the brake cylinder, which leads to the start of the brake disc and brake pad.

The internal end is in the capacity of slight friction; Another possibility is that there are hard spots on the surface of the brake pads, or foreign objects such as fine sand particles between the brake disc and the brake pads. First of all, it is certain that this kind of problem will not have a significant adverse effect on the working performance of the vehicle's braking system.

In addition, if you want to treat, it is recommended to go to a specialized shop to check whether the brake cylinder has a bad return phenomenon, or to remove the brake pads and polish the friction surface, which will generally be significantly improved.

The brake master cylinder, also known as the "brake master cylinder" and "brake master cylinder", is the main part of the vehicle braking system. According to different vehicles, it is also divided into two kinds of air brake master cylinder and oil brake master cylinder, under normal circumstances, most of the brake master cylinders of passenger cars (such as cars, micro-buses, etc.) use oil brake master cylinders. The brake master cylinder of commercial vehicles (such as trucks, tractors, etc.) generally uses air brake master cylinders.

The abnormal sound of the sunroof slide.

Some car owners rarely use the sunroof of their car, and once used, the sunroof will make a "squeak" sound. Experts said that the situation of the sunroof of the car is the situation that many car owners often "only know how to use, but do not know maintenance". In general, the sunroof should be lubricated at least once every two or three months.

Otherwise, it will make an abnormal noise. , poor movement. and even burn out the motor.

Experts said that car owners can use cotton cloth, gauze to wipe the track of the slide rail, after wiping clean, apply a small amount of grease to the slide track, generally 4S professional maintenance using tiger head hotolube or Kruber car sunroof grease. The maintenance interval is three to four months.

Do not use petroleum jelly or motor oil, as it will pollute the interior and emit harmful odors.

Abnormal noise caused by the door hinge.

After the hinge is used for a long time, it will greatly increase its friction, and then produce abnormal noise, then what we need to do is to apply grease, you can use the door hinge grease of the tiger head hotolube, which is the grease used for 4S maintenance. In this way, the friction will be greatly reduced, and there will be no abnormal door noise. The maintenance interval is three to four months.

Abnormal noise from the door limiter.

If the door limiter is not regularly maintained, it will also make the door make abnormal noise, what we need to do is to apply some of the same grease as the door hinge, so that the friction of the door limiter will be greatly reduced, and the abnormal noise of the door will be solved.

Is this sound coming from inside the car or from outside the car?

If it's in the ZHI car.

When the DAO is issued, it is necessary to check whether the air capsule under the lower steering wheel and the cross universal joint inside the direction column are normal. If these two parts are worn or malfunctioning, the fault phenomenon you mentioned will occur.

If there is an abnormal noise on the outside of the vehicle, it is necessary to check whether the plane bearings above the lower two front shocks are worn. Whether the ball head of the steering machine is loose. The rack and pinion inside the steering machine are worn. The failure of these 3 components will cause the vehicle to malfunction as you describe.

Please check whether the hand pick is to put some plastic products to cause resonance during the driving of the car, or check whether the outer door lock of the right front and rear doors is loose, which can also lead to resonance between the travel. Because sometimes it's the little glitches that don't make it easy for us to notice. If there is no problem after checking, then please go to the 4S point and ask someone to check the right front and rear shock absorption, check the chassis screws, check whether the door panel has loose screws, and check whether the inner door panel has buckle breakage.

I hope to solve the abnormal noise as soon as possible, because it is really annoying to have abnormal noise during driving.

Check to see if the shock absorbers are worn.

The sound of the brake disc is not stuck on a small rock or something.

The reason why there is a squeaky sound in the car:

One possibility. It is due to the phenomenon of poor return of the brake cylinder.

As a result, the brake disc and the brake pad are always in slight friction; Another possibility is that there are hard spots on the surface of the brake pads, or foreign objects such as fine sand particles between the brake disc and the brake pads. First of all, it is certain that this kind of problem will not cause obvious adverse effects on the working performance of the vehicle braking system, and if you want to deal with it, it is recommended to go to the repair shop to check whether the brake cylinder has a poor return phenomenon, or the brake pads are removed and the friction surface is polished, which will generally be significantly improved.

It is very likely that there is a lack of oil in the shock absorption, and many of them are abnormal noises caused by lubrication. Of course, the possibility of damper damage is not ruled out, and it is safer to drive slowly to the car repair shop for inspection!

This is the abnormal sound of the chassis, which needs to be checked in the maintenance shop to determine that there is a problem with the chassis parts, which is generally caused by damage to the ball joint, lower avoidance, and shock absorber.

It may be a problem with the car's shock absorption and steering system.

When the vehicle makes abnormal noises during driving, it is likely that there is a problem in these places.

Hello, dear, the exclusive technician of the car master will serve you, attentively, carefully and attentively answer your car questions, find solutions and solutions to the corresponding problems for you, and will definitely provide you with satisfactory service! I hope my answer can help you!

Dear, hello, the vehicle has a sizzling sound when driving, the reasons are as follows: the first vehicle brake pads are too thin, resulting in this phenomenon needs to be checked in time, if the thickness of the brake pads is less than one centimeter, it needs to be replaced in time.

Abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment. Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

Before dismantling, it is necessary to carry out an inspection to preliminarily determine the location of the fault, and then the analysis of the abnormal noise characteristics of the engine can basically diagnose the location, cause and degree of abnormal noise, and avoid the blindness of dismantling.

When the car creaks, I think there should be a problem inside the car, but the specific problem should still go to the 4S store and let the professional master help you take a look. If there is a problem with the car, it should be repaired in time. Don't drive a breakdown car on the road.

The car creaks when it is driven, depending on the sound from the **, whether it is under the seat of the car or under the chassis, if it is the chassis, it may be a problem with the shock absorbing spring of the car.

One possibility is that the brake cylinder has a poor return phenomenon, resulting in the brake disc and the brake pad are always in slight friction; Another possibility is that there are hard spots on the surface of the brake pads, or foreign objects such as fine sand particles between the brake disc and the brake pads.

It is certain that this kind of problem will not cause obvious adverse effects on the working performance of the vehicle braking system, and if you want to treat it, it is recommended to go to the repair shop to check whether the brake cylinder has a poor return phenomenon, or after removing the brake pads, the friction surface is polished, and it will generally be significantly improved.

The car sometimes squeaks while driving, it is recommended to check the steering of the car, the ball head rubber sleeve, and the shock absorbing spring, which may cause these problems.

Noise problems should be checked.

1. There are foreign objects in the tiresWhen we drive, the most abnormal noise we hear is probably from the tires. Of course, tires will also have a sound in normal driving, and we must be familiar with this sound. In this way, once there is an abnormal sound in the driving of the vehicle, we can appear in time.

Second, the abnormal sound of the suspension, in the normal driving process, if there is a problem with the suspension or in the abnormal noise, it is difficult for us to judge the specific cause. So for the driver, for the normal sound of our suspension is also to be mastered.

Third, there is an abnormal sound in the body, in addition to the normal sound of the body. The most abnormal noise is our body. Because many parts can be fixed on the body, no matter if there is a little problem, it may make the body make abnormal noise.

And the abnormal noise of the body is still the most difficult to deal with, because it is difficult for us to see that there is a problem in the stationary state. We can only solve the abnormal sound of the body by reinforcing the visible looseness, and there is no good way.

1.Engine: Whirring is a problem with the bearing, squeak is a problem with the starter or belt;

2.Gearbox: The click sound means that there is a problem with the gear, the rustling sound is the problem of the bearing, and the click sound means that the gearbox is seriously damaged;

3.Brakes: The sound of metal friction indicates that the brake pads need to be replaced;

4.Steering system: A rattling sound indicates a problem with the steering ball joint or rubber sleeve.
