What is the solution to the resonance and squeak of the car door?

The solution to the resonance and abnormal sound of the door is: 1. Clean the door sludge and spray lubricant on the hinge; 2. Apply sesame oil or butter to the hinge part; 3. Clean the dust on the windshield; 4. Replace the door seal; 5. Check whether there is too much dust in the sealing strip on the window, causing friction between the dirt and the glass; 6. Check whether there is any problem with the glass lifter. The causes of the resonant noise of the car door are:

1. The hinge is jerky and produces abnormal noise; 2. The windshield enters the dust; 3. The sealing strip of the door is aging; 4. There is an abnormal sound when the electric glass is lifted.

The hinge is a part that connects the door and the body, just like the hinge on the door, often opening and closing the door vigorously, which will cause serious wear and tear of the door hinge, and the door will not be closed tightly after a long time, resulting in abnormal noise.

In the problem 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. 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.

How to identify the sound of a car:

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.

Here's how to fix it:

Step one, rule out which door it is. If you are not sure whether it is the front door or the rear door, find a rough road to ensure that there is a sound at low speeds, in the direction of fastening the seat belt and confirming the safety of driving, slowly open the driver's door and continue to drive, if it still rings, it proves that it is the back door, so that the friend sitting in the back also confirms that the door is ringing.

Step 2: Eliminate whether the sealing rubber rings or the door lock rings. I cut the newspaper into 10 centimeter-wide strips, separated the contact surface between the sealing strip and the car door in sections, closed the door tightly and drove the test, if the abnormal noise disappears, it means that the sealing rubber rubbing sound, and if there is a sound, the sealing rubber is excluded. Basically, cars within 3 years old have abnormal seals.

Step 3: Eliminate the door lock ringing. Find insulating black tape to wrap the lock post of the door lock with black tape, close the door tightly and drive, and the abnormal noise disappears to prove that the door lock hook and the lock post friction produces abnormal noise, my car is this problem.

Step 4: Problem solving.

1. If the door lock rings, you can use colorless transparent glue to wrap the lock post in a layer, and at the same time lubricate the door lock with lubricating oil that is not harmful to the rubber, which may become a regular homework, because the transparent glue will break and the lubricating oil will dry after a long time.

2. If it is a problem with sealing rubber, you can find a bottle in **; Sealing tape maintenance wax, the entire door and door frame sealing strip is wiped over, and the effect really works. The packaging is good, and I have seen the technician in the 4S store also use it. The new car can also prevent the rubber hardening of the sealing strip and restore the toughness of the sealing strip.

3. The trunk door can also be solved by the above methods.

4. If none of the above methods can be ruled out, it means that the interior material is rubbing, and you can regularly use spray lubricant to spray a little in the gap between the interior material links.

1. The hinge is jerky and produces abnormal sound The hinge is a part connecting the door and the body, just like the hinge on the door, often opening and closing the door vigorously, which will cause serious wear and tear of the door hinge, and the door will not be closed tightly after a long time, resulting in abnormal noise. Solution: The hinge is jerky, the essence is insufficient lubrication, and some sludge may be generated, it is best to buy a bottle of anti-rust lubricant, clean the sludge first, and then spray lubricant on the hinge.

If there is no condition, you can also apply sesame oil and butter instead of lubricant, but do not use engine oil instead of lubricant, because engine oil is more likely to be contaminated with oil.

2. When the windshield enters the dust and drives in a relatively large area of wind and sand, it is often found that the windshield makes an abnormal sound, and whenever the vehicle drives to a bumpy road or an undulating road surface, it will make a "creaking" sound, which is particularly annoying. Solution: Generally, this situation will occur on the front windshield, you may think that the central control plastic cloth bayonet is not strict, in fact, the windshield is caused by dust, as long as the adapter plate is removed, do a cleaning can solve the problem.

3. The function of the aging sealing strip of the door sealing strip is to prevent rain and dust from entering the compartment, because the sealing strip is a rubber product, it will gradually age and damage with the wind and sun, and we will obviously feel the wind noise and friction sound when driving. Solution: If the sealing strip is seriously damaged and aged, it is recommended to replace it directly, the value of maintenance is not high, it is recommended to regularly clean up the dust and rain between the gaps of the sealing strip when using the car, so as to prevent aging.

4. Many car owners will encounter this situation, that is, when the window glass is lifted, it will be accompanied by abnormal vibration. Solution: Check first to see if there is too much dust in the sealing strip on the window, which causes friction between the dirt and the glass, if this is the case, clean the sealing strip to solve the problem.

There is also a situation where there is a problem with the glass regulator, and it is best to go to the repair shop to overhaul it.

Several causes and solutions for abnormal door noises:

1. There are small things in the door trim panels, such as lighters, coins, etc. Just take it away.

2. The interior trim panel or audio is loose, this fault can be found by shaking by hand, or pressing the abnormal sound when driving, if the abnormal sound disappears, it is a fault here, and it can be re-tightened.

3. The door hinges (hinges) are rusty, this phenomenon will be heard when the door is opened and closed, clean the hinges and apply some butter.

4. The door sealing strip is aging, and the door sealing strip will also have this failure if it has not been maintained for a long time, the best way is to buy a bottle of silicone grease to maintain it yourself, apply the silicone grease to the sealing strip, and wipe it off after absorbing for an hour, it will have a good effect.

5. If the door lock block is in poor contact, there is a gap or the lubrication is not good, you can apply butter at the lock block or wrap two circles of waterproof tape around the lock pin.

Extended information: 1. Door outer plate: the thin steel plate is stamped and formed;

2. Door reinforcing beam: that is, the door anti-collision beam, which has a closed round pipe section and a high-strength steel plate stamping form;

3. Door inner plate: an important support plate is also the installation body of the door accessories, and the thick thin steel plate is generally used. It has the following characteristics:

It is necessary to stretch out the deeper perimeter to form the door thickness;

Convex and concave tables of various shapes need to be stamped out on the board surface for the installation of accessory mechanisms;

Stamping out a variety of stiffeners to improve rigidity and reduce vibration and noise.

4. Door reinforcing plate: set up for partial reinforcement of the door body.

The part where the door accessory mechanism is installed on the inner plate surface improves the stiffness and connection strength of the installation part;

Thick reinforcing plates are arranged at the hinge of the door body, the opening limiter and the door lock, etc., and are welded with the inner plate of the door;

The reinforcing plate is set at the inner and outer window sill of the door, and the fixed installation structure of the cross-sectional form and sealing strip should be considered.

5. Door and window frames: most of them are stamped or rolled by thin steel plates. Key points to consider in the cross-section of the window frame structure:

Proper fit with the side wall door frame of the body;

Good sealing performance, layout and installation structure of sealing strip and glass guide trough;

Meet the requirements of glass lifting;

the stiffness of the window frame itself, which has a greater impact on the sealing;

The connection structure between the window frame and the inner and outer panels.

Door vibrations can be tried by wrapping some adhesive tape on the door buckle, or adding some lubricating oil to the hinges.

The door and the body are connected by hinges, just like the door at home, and the hinges are used for a long time to make a sound is normal, in order to ensure that the pulley is smooth and silent for a long time, you can regularly add some lubricating oil every 2-3 months for maintenance.

If you have been using the car for a period of time, you should check whether the door seal is aging, because the seal is a rubber product, and over time, the seal will gradually age and break, which will make the driver and passengers feel the obvious wind noise and friction sound. If the seal is aging and damaged, it is recommended to replace it directly, and regularly clean the dust and rain between the gaps of the seal when using the car regularly, which can prevent aging.

If the door inner cable hits the door panel, the sound is still very obvious, what we have to do is to disassemble the door trim panel first, and then wrap the door inner cable with a small sponge, so that there is no noise, which is also one of the reasons for the abnormal noise of the car.

If it is an abnormal sound generated by the door itself, the reason for this problem is that the door lock post is installed outside, resulting in the door itself and the car body is not very tight, at this time, we need to adjust the door lock post a little, little by little, until the door and the car body are tightly combined.

It is to wrap some adhesive tape on the door buckle, and then perfectly solve the problem of abnormal door noise when bumping, other car owners can try it if they encounter abnormal door noise, although it looks a little unsightly.

The door and the body are connected by hinges, just like the door at home, and the hinges are used for a long time to make a sound is normal, in order to ensure that the pulley is smooth and silent for a long time, you can regularly add some lubricating oil every 2-3 months for maintenance.

If you have been using the car for a period of time, you should check whether the door seal is aging, because the seal is a rubber product, and over time, the seal will gradually age and break, which will make the driver and passengers feel the obvious wind noise and friction sound. If the seal is aging and damaged, it is recommended to replace it directly, and regularly clean the dust and rain between the gaps of the seal when using the car regularly, which can prevent aging. 2019

Reasons for the abnormal sound and resonance of the door: 1. Whether there are individual small things in the door trim panel, such as lighters, coins and other objects; 2. The interior panel or audio is loose, this fault only needs to be shaken by the owner's hand to be found, or the abnormal noise is pressed when driving, if the abnormal sound disappears, then there is a fault here, and it can be tightened again; 3. If the door lock block has poor contact, gap or poor lubrication, it can be solved by applying butter at the lock block or wrapping two circles of waterproof tape around the lock pin; 4. Poor lubrication of the door hinge (hinge), this phenomenon can generally be heard when the door is opened and closed, and the owner only needs to clean the hinge and apply some butter; 5. If it still rings, it should be that there are too many dust particles on the side of the hinge near the door, and it is recommended to clean it carefully.

If the abnormal noise is obviously an assembly problem, just let the 4s disassemble it for free. But sometimes, because of the loud sound, some parts in the car will resonate with the sound, that is, the abnormal sound of the iron plate that I told you after the sale. At this time, it is necessary to remove the door panel and make sound insulation at the resonance, which can be solved.

Several causes and solutions of abnormal door noise:1. Abnormal sound caused by unsmooth hinges:

The hinge is the part that connects the door and the body, just like the hinge installed on the door, often opening and closing the door too hard will cause serious wear and tear of the door hinge, and the door will not be closed tightly for a long time, which will cause abnormal noise. Solution: The hinge is rough, the essence is insufficient lubrication, and there may be some sludge if the tung is not high.

It is best to buy a bottle of anti-rust lubricant, clean the sludge first, and then spray the hinge with lubricant. If you don't have the conditions, you can also use sesame oil and butter instead of lubricants, but don't replace them with oil, as oil is more likely to be contaminated by oil. 2.

Windshield dusting: When driving in areas with large winds and sand, it is often found that the windshield makes abnormal noise, and every time the vehicle walks to an empty position on a bumpy road or undulating road, it will make a creaking noise, which is particularly annoying. Workaround:

Typically, this happens on the front windshield. You may think that the central control plastic cloth bayonet is not strict, but it is actually caused by dust entering the windshield. Just remove the adapter plate and do some cleaning to solve the problem.

3.Door seals are old-fashioned: The purpose of the seals is to prevent rain and dust from entering the cabin.

Because the sealing strip is a rubber product, it will gradually age and break with the wind and sun, and we will clearly feel the wind noise and friction when driving. Solution: If the sealing strip is seriously damaged by aging, it is recommended to replace it directly, and the maintenance value is not high.

It is recommended to regularly clean the dust and rainwater between the gaps of the sealing strip when using the car to prevent aging. 4.Abnormal lifting noise of electric glass:

Many car owners will encounter this situation, that is, when the window glass is lifted, it will be accompanied by abnormal vibration noise. Solution: First check the sealing strip on the window for too much dust, causing dust and glass friction.

If this is the case, cleaning the seal will solve the problem. There is also a situation where there is a problem with the glass regulator and it is best to go to a repair shop to repair it.
