What is the reason for the abnormal noise in the rear of the car, and the abnormal noise in the car,

The abnormal noise of the shock absorber is generally divided into several situations, normal use and wear, external force damage or intermittent due to road conditions, weather and other reasons are also possible, but if the abnormal noise is serious, affecting the use of the car, it must be replaced. There may be several reasons for the abnormal noise of the general shock absorber. Damage to the rubber sleeve of the balance bar, or a gap in the connecting ball joint.

Shock absorber oil leakage or.

Loose chassis generally occurs in older cars, when the car is driving in bad road conditions, the steering wheel will feel unstable, the bottom of the car will also come out of the abnormal sound, usually the old driver can feel the overall a little loose, when encountering such a situation, it means that the chassis may be loose, and the reasons for this situation are divided into several, only by understanding the reasons, can we better prevent this problem from happening.

The first reason is the aging of rubber parts, we all know that the elasticity of rubber is particularly good, which can buffer the friction between parts and reduce noise at the same time. However, this kind of thing has a lifespan, and it will age after a long time, and the elasticity is not as good as before, so the buffering capacity will decrease, resulting in abnormal noise in each part, so it is necessary to check these rubber parts regularly and replace them in time.

The second possibility is the reason for the shock absorber, the main role of this part is to inhibit **, when the car is driving in the dustpan section, it will have an impact with the road surface, and the shock absorber can well ensure the smoothness of the car, if the shock absorber is damaged, there will be a scoop phenomenon, so that the chassis is loose, so usually check the shock absorber, if there is a leakage to repair in time.

The third is the clearance of the parts, that is to say, the ball head may be loose, this part is like the joint of the human body, if the ball head is loose, there will be a large gap between the lever and other connected parts, if the gap is too large, when crossing some dustpan roads, the screws between the subframe and the suspension will be loose, then the chassis will become loose, so usually check these two parts.

Thank you for adopting.

Abnormal noises are inevitable. As long as there are almost all cars, 10 tens of thousands of A-class cars, millions of S Mercedes-Benz, after a period of use, there will be abnormal noises.

This is determined by the plastic interior components of the car, many plastic components in the car interior are fixed by elastic pressing, and the plastic material will age and shrink elastically after a few years, so the pressure is not as tight as the new car, and there will naturally be abnormal noise. There are also interior panels of the model, all of which are fixed by plastic buckles, which will age and shrink after a few years, and the driving is in a state of vibration for a long time, especially in bumpy road conditions, and the buckles will always be impacted by external forces, which will accelerate the attenuation of the buckles.

In addition, with the aging of the entire body and chassis, especially the aging of the chassis rubber bushing, the vehicle will be more prone to resonance, and the NVH of the vehicle will become significantly inferior to that of the new car.

In short: the car is a consumable, generally speaking, the life of the car is 7 years, and the quality of the whole car will accelerate after 7 years. At this time, if you want the most quality of life, you have to change cars.

Hello, you said about this situation. It is generally caused by the improper installation of the interior panel of the vehicle. If any piece of abnormal noise. You take that piece off and reinstall it. It should be fine.

Sometimes a mineral water bottle is super loud when it is placed on the car door, and the key is that you can't hear it in the car... Empty the car first, and find the abnormal noise point first. Both of my cars are noisy, but as long as you find out which one is ringing, it will be easy to solve.

Solution: 1. No matter what "abnormal noise", find the problem, repair it in time, and do not delay, which is the premise. 2. According to the results of the inspection, timely treatment, repair and fixation of relevant faulty parts or personnel reasons such as missing, reverse installation and unfastening.

Eliminate potential safety hazards.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! There may be abnormal noises in the back of the car:1

If there is an abnormal noise on the road, it is an abnormal sound such as bearings or brake pads! 2.If it is an uneven road, the abnormal sound is shock absorption, and there is a loose abnormal sound of the swing arm ball head and the balance rod ball head or rubber sleeve!

Solution: Lift up, turn the tires, and check the bearings for abnormal noises. Use a crowbar to inspect all ball sleeves for damage or looseness.

If there is looseness or abnormal noise, give priority to replacing the faulty parts for the next step of troubleshooting!

I've changed everything I can, what else can I do? If the spring is not compressed and deformed, there will generally be no abnormal sound, but can the spring be deformed when driving?

There are always so many small problems in the process of daily car use, which only the owners of long-term use know. Small problems are the problems of any car, although it does not affect the normal driving of the vehicle, but it is very annoying, and the most annoying of them is the abnormal noise of the car.

This depends on the fact that your abnormal noise is sent from **, and it is recommended that you go to a local professional repair shop to check it.

The abnormal sound of the back of the car may be caused by something in the trunk or due to the loosening of the interior panel, and when some models reach a certain speed, the interior panel will cause resonance, which will also cause abnormal noise in the back. In addition to checking the fixation of items in the trunk, it is also recommended to check whether the connection between the rear wheel suspension and the transmission shaft is firm.

Abnormal sound of the gearbox: If there is an abnormal sound inside the gearbox during driving, and it disappears after stepping on the clutch, it means that the noise** is a gearbox failure, which may be caused by the wear of the gearbox bearing or gear and bearing spots.

Abnormal tire noise: The tire noise must be rhythmic, and the fast speed of the car is high. If it is a low abnormal sound, it is most likely that the tire tread is deformed, lifted, worn seriously or the air pressure is insufficient, and if it is a clicking sound, it may be that the tread is mixed with small stones.

If the tires are whirring, and the body is obviously shaking or even running in the wrong direction, it should be a tire burst, and it is recommended to get out of the car and change the tire.

The abnormal sound on the rear right side of the rear of the car may be caused by something in the trunk or a loose interior panel. When some models reach a certain speed, the interior panel will resonate, which will also cause abnormal sound at the rear end. Here's why it causes and how to fix it

Check the rear wheel suspension: often when the car is driving on a bumpy section of the road, the gap in the interior panels will become larger, resulting in noise. There is an unusual noise in the rear of the car.

In addition to inspecting the contents of the trunk, it is also advisable to check that the rear wheel suspension and the propeller shaft are securely attached. Resonance generated by interior panels: It is normal for there to be noise behind the car, especially when the trunk of the car is equal to empty, which is most likely to cause noise behind it.

Some MPV models, SUV models, and vans are the most prone to noise. When the trunk of these cars is not loaded, the interior panels may resonate and make noise.

It may be caused by loose screws under the chassis, or it may be due to the exhaust pipe. It is recommended that the owner go to the 4S shop or repair shop for inspection and treatment in time.

If it comes from under the chassis of the car, it may be that there is a problem with the suspension of the car, or that the shock absorber or other auto parts are loose or aging, and the small parts that are loose can be replaced or tightened.

The exhaust pipe and the engine are connected by a soft connection, which may be caused by the damage and aging of the soft connection after the car has been used for a long time. The exhaust pipe and frame connection are held in place by several rubber rings, which can be checked for damage or rubber deterioration. There are seals between the exhaust pipe and the soft connection, the soft connection and the engine, and the seals can be checked for damage.

In addition, the blockage of the three-way catalytic converter will also cause abnormal noise in the exhaust pipe, and it is recommended that the owner regularly clean the three-way catalytic converter. There will also be abnormal sound if there is water stored in the exhaust pipe, so you need to clean the water in the exhaust pipe. (Photo by photo:.)

The reasons for the abnormal noise behind the car are as follows: 1. The body stiffness is not enough: it causes the vehicle to be deformed during driving, the door and the frame are rubbed or shaken, or some places are dewelded, resulting in friction between the steel plates.

2. Engine problems: engine belt slippage, generator, water pump, power steering pump bearing damage; 3. Gearbox problems: caused by bearing or gear wear and bearing spots; 4. Caused by the failure of the shock absorber or the loosening of the suspension parts.

Extended information: It is normal for the car to have a noise in the back, especially when the trunk of the car is quite empty, and the rear is prone to noise. Some MPV models, SUV models and brigade cars are prone to noise in the back, and the trunk of these cars may resonate and make a sound when there is no thing in the trunk.

The reasons for the abnormal noise in front of the car are: 1. The abnormal noise of the tires: the tire tread is deformed, the bag is lifted, the wear is serious or the air pressure is insufficient; 2. Abnormal engine noise:

Problems with parts or kinematics; 3. Abnormal sound of the body: the rigidity of the body is not enough, which leads to the deformation of the vehicle during driving, and the friction between the door and the frame or the dewelding of some positions produces friction between the steel plates. The solution to the abnormal noise in front of the car is:

1. Check whether the tire tread is deformed, packaged, seriously worn or insufficient air pressure; 2. Check whether there is any problem with the zero tease training parts of the engine; 3. Check whether it is an abnormal sound of the body.
