The 2018 Dongfeng Fengshen Ax7 started slowly, and the direction of the hit squeaked in the directio

Abnormal noise in the car. 1. Loud on low-speed bumpy road sections: the sound of the storage compartment items in the car, the items in the glove box or the wire tapping of the electronic equipment installed later. Sometimes this sound is refracted back through the ceiling, and you feel like the ceiling is ringing.

Reason: In this case, pay attention to check the storage compartment, the inside of the bootcase, the sunglasses in the glasses case will also ring, and the wiring of the dash cam installed after is not loose.

Check method: clench your fist and knock on some areas of the car, when the knock to a certain part of the sound appears, determine what is around the whole part nearby, take it out or fix it one by one, and confirm it in the knocking, if the sound disappears, it means that the thing you take out or fix is the source of the abnormal sound.

2. The second situation: if there is abnormal noise regardless of low speed or high speed, and the faster the speed and the faster the frequency, it means that it is related to the transmission mechanism, and the transmission part outside the car should be checked, such as tires, ball cages, etc.

Reason: This sound is accompanied by transmission or vibration, and is not the same as the fragmented clicking sound in the car. It's easy to tell the difference, and you can find out when you go to the repair shop and turn the tires on the shelf.

3. The third case: It has nothing to do with the speed of the car, and the sound is irregular, like the sound of knocking outside the car.

Reason: In this case, pay attention to the perimeter of the door frame, the loose items in the trunk, or check the chassis of the car. Check whether there are fallen leaves or debris under the front windshield that are blown by the air current, or whether it is the shaking and knocking sound of loose objects under the car body or the trunk (such as water bottles or debris shaking in the trunk); Or there are plastic bags or other debris hanging under the car.

Causes of engine noise:

1. The engine noise is caused by the wrong oil condition.

2. Engine noise caused by insufficient belt tightness or aging of the belt.

3. The engine noise is caused by leakage in the intake and exhaust pipes.

4. Poor fuel quality, high engine noise.

5. The abnormal noise of engine parts makes the engine noisy.

6. The engine has a "tempering" fault, resulting in high engine noise.

Solution: 1. Check the tightness of the engine belt.

2. If you need to check the intake and exhaust pipes.

3. Check the quality of the fuel.

4. If the screw of the guard plate under the engine is loose, the engine cannot be fixed, and it will shake violently and produce noise when working. Here's a comparison.

A common glitch is to tighten or adjust the engine underguard screws.

5. When the valve of the engine has too much carbon deposit or the timing adjustment is not right, the engine will have a "poof" sound, and the gas will be cleaned at this time.

The door is carbon, and the timing of the gas distribution can be adjusted.

Summary. 1. This may be caused by the loss of battery power, or it may be that there is a quality problem with the spark plug, and it may be that the carbon deposit of the engine is too much, which needs to be checked.

2. There are many reasons why the vehicle cannot catch fire, it may be the failure of the power supply system, check whether the battery is losing power, it may be that the spark plug is broken, it may be that the gasoline pump is broken, or it may be that the oil circuit is blocked.

3. In this case, most of the reasons are due to the lack of power in the battery of the original car, that is, the loss of power, it is recommended that you go to the auto repair shop to test the output voltage of the battery.

Dongfeng Fengshen **ax7 does not catch fire and shows the direction of rotation.

Hello dear. 1. This may be caused by the loss of power of the electric sluggish bottle, or it may be that there is a quality problem with the spark plug, and it may be that the carbon deposit of the engine is too much, which needs to be checked. 2. There are many reasons why the vehicle cannot catch fire, it may be the failure of the power supply system, check whether the battery is losing power, it may be that the spark plug is broken, it may be that the oil pump is broken, or the oil circuit is blocked.

3. In this case, most of the reasons are due to the lack of power caused by the appearance of the original car's battery, that is, the loss of electricity, it is recommended that you go to the auto repair shop to test the output voltage of the battery.

The central control in the car cannot be displayed, the one-button start cannot be ignited, and the headlights of other cars will be lit, which is a loss of power.

In the pro. It may be that the battery is losing a parent.

You honk. Will the sound be a little weaker than usual?

If not, it should be that the engine has serious carbon deposits.

So how does it show turning the steering wheel? Could it be that the steering column is broken?

Hello, this indicates that there is a problem with the steering system.

The steering column will not be not.

If it is fast after turning, it will deviate greatly from the direction.

215 Dongfeng Fengshen AX7 turns on the warm air, squeak and squeak is because of the sound of the blower, most of the sound of the blower is caused by poor bearing lubrication, and it may also be that there are foreign objects in the blowerPoor lubrication only requires adding a portion of oil or grease to the bearing.

Use of warm airThe car heater is to flow the cooling water of the engine through a heater core, and then use a blower to blow the cold air through the heater core to heat the air, so that the temperature in the car rises, and the temperature, air cleanliness and air flow in the cabin are adjusted and controlled in a better state, so as to provide a comfortable riding environment for the occupants and ensure driving safety.

Fan disassembly and cleaning, some models are normal, because of the plastic thermal expansion and contraction, if the water temperature is normal, or has been abnormal noise, it means that there is a problem, the most common situation is that the blower is abnormal, replace the blower, because you can't see the real car, so you can't make an accurate.

Summary. Hello, your situation is pro, consider the following reasons: 1. The sound of the direction column rubbing against the foot pad. If you find that the abnormal sound comes from under the steering wheel when you hit the steering wheel, you should check the steering column and the car mat, because the mat installed behind the car is too large, and there is direct contact with the steering column, with the rotation of the steering column will produce friction, if there is a lack of lubrication, there will be friction sound, in this case, as long as you apply some lubricating oil.

2. The airbag hairspring is faulty. If you find that the sound comes from the steering wheel, most of the problems are caused by the interference of the airbag hairspring in the steering wheel, remove the steering wheel airbag hairspring and apply some butter to see if it still sounds, if it still rings, replace the airbag hairspring, because the airbag hairspring is damaged. 3. Lack of oil in the plane bearing of the shock absorber.

When playing the steering wheel, if you notice an abnormal noise coming from outside the car, it may be the sound of lack of oil in the plane bearing of the shock absorber. Just open the hood and listen to see if the sound is coming from the position of the top seat of the shock absorber, so that you know if it is the sound of the flat bearing of the shock absorber.

Rear shock absorber squeak. The steering wheel rattled.

Hello, if you are blind early, consider the reason for the cover 1, the sound of the direction post rubbing against the pad. If you find that the abnormal sound comes from under the steering wheel when you hit the steering wheel, you should check the steering column and the car mat, because the mat installed behind the car is too large, and there is direct contact with the steering column, with the rotation of the steering column will produce friction, if there is a lack of lubrication, there will be friction sound, in this case, as long as you apply some lubricating oil. 2. The airbag hairspring is faulty.

Lack of oil in the plane bearing of the shock absorber. When playing the steering wheel, if you notice an abnormal noise coming from outside the car, it may be the sound of lack of oil in the plane bearing of the shock absorber.

Just open the hood and listen to see if the sound is coming from the position of the top seat of the shock absorber, so that you know if it is the sound of the flat bearing of the shock absorber.

The vehicle is driving on uneven roads, the rear shock absorption is abnormal, and the steering wheel shakes abnormally.

In this case, it may be a problem with the lack of purity of the shock absorber body or the loosening of the chassis parts, which may cause resonance or collision with the abnormal sound of the production car. It is recommended to replace the anti-retarder assembly. If it is a quality problem of the shock absorber itself, it can only be replaced completely.

The road surface is a little uneven, and the back keeps gurgling.

In this case, there is an abnormal sound when the road surface is uneven.

What you mean is normal.

No, I mean this shock absorption problem will appear in your case.

Why doesn't my Fengshen h30 ring.

If this happens to you, it's likely to be a shock absorption problem.

Hello, I don't know how many kilometers you have driven, if you feel that there is no abnormal noise in the use, try using a good synthetic engine oil.

The reason for the abnormal noise of the Dongfeng Fengshen AX5 engine:

1. The abnormal sound of piston knocking on the cylinder, the so-called piston knocking cylinder abnormal grinding sound, refers to the abnormal sound caused by the piston side slapping the cylinder wall. Generally speaking, when the direction of the axial force generated at the top of the piston changes from the piston to the work stroke, there will be a squeak of the piston knocking cylinder;

2. Crankshaft bearing (large watt) and connecting rod bearing (small watt) abnormal sound ruler, these two kinds of abnormal sound can be distinguished from the sound part and sound frequency, generally the sound of large watts is low, and the sound of small watts is high. Secondly, the method of breaking the cylinder can be used to distinguish it, because when the abnormal sound of individual small watts, if the ignition or fuel injection of the cylinder is broken, the abnormal sound will be weakened or eliminated; If the big tile sounds, the sound will only weaken or remain unchanged when the cylinder is broken, but it will never disappear;

3. Abnormal noise of the intake and exhaust system, when the intake manifold leaks, the engine will produce a sound when it idles, and the sound will intensify with the increase of engine speed; When the exhaust manifold is leaking, a sudden popping sound is heard when the engine accelerates;

4. When the air filter is blocked, the engine will be dull and produce abnormal sound when accelerating; When the exhaust system is clogged, there is sometimes a backfire explosion when the engine accelerates; When the air flow meter leaks from the throttle rubber hose, it will also produce a backfire popping sound when accelerating sharply.

Millions of car purchase subsidies.
