What should I do if the Mercedes Benz chassis has an abnormal sound and the transmission system rumb

If the car makes an abnormal noise when idling, and the abnormal noise disappears when the clutch is pressed, it means that the abnormal noise is caused by a faulty transmission. Abnormal noise in the gearbox is usually caused by wear of bearings or gears. When the car is refueling while driving, the noise coming from the chassis can be heard.

When the gear makes a "click" sound, then the bearing failure will make a "rustle" sound, and in severe cases, it will become a "click" or "click" sound. First of all, we judge the riding fault based on a small percentage of judgments. If it's money, now I think it's probably a small noise caused by loose bolts or badly worn door guards.

If you think about it after the tradition, it may be a consequence of your excessive wear clearance, caused by the link between the MacPherson suspension and the shock. You can park the car in a relatively quiet place and turn off the engine, then press your hands on the four shock absorbers, and the body part will move up and down, making the body shake up and down. If you listen carefully during the shaking, you can hear which part is making the sound.

If it is not the sound of tires rubbing against the ground, it can only be the sound of damage to the outer cage.

Abnormal noise can be eliminated by replacing the outer cage. If the tires rub against the ground, it is recommended to do four-wheel alignment. It is the abnormal sound of the gearbox, and there is an abnormal sound when the car idles.

After checking the clutch, the abnormal noise disappears, indicating that the abnormal noise is caused by a faulty gearbox. The sound of squeak engine vibration in engine compartment airports is normal, but there are special cases. Metal howling of belts is usually caused by belt slippage.

The most common failures of axles are deformation and breakage, and there are also failures caused by displacement and wear.

When you are repairing, you should check whether there is a problem with the gap between the chassis connector or buffer. To maintain the chassis in winter, it is necessary to thoroughly clean the chassis to prevent rust. First of all, the chassis should be thoroughly cleaned.

If there is too much dirt on the chassis, it is necessary to wash it again with degreasing detergent to reveal the original "true color" of the chassis before you can start anti-rust care. In a professional beauty shop, you can lift the car to the lifting frame for chassis cleaning, wiping, and anti-rust care. After cleaning, be sure to wait for the moisture on the chassis to dry before you can carry out anti-rust care.

When careting, be sure to keep the spray evenly to form a long-lasting and uniform anti-rust coating. After all the work is completed, it will be dried naturally for 5-10 minutes, and the chassis anti-rust treatment will be completed.

Hello! Glad for your question.

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.

It may be that the wear and tear of the chassis is more serious, it may be that the screws are loose, there may be abnormal bearings, and the suspension or brake system should be checked at this time, and the specific problems should be analyzed.

I think that when this abnormal noise occurs again, it is necessary to conduct an inspection of the car in time, and then find out what the problem is, if you can't solve it, it is recommended to go directly to the car repair shop for maintenance, and detect the cause of the problem in time, so as not to have a serious impact on future driving.

It may be that the wear is severe, it may be that there is friction between the shock absorber buffer and the shock absorber, it may be that the wheel is unstable or the propeller shaft is unbalanced.

Fault: Rumble, noise, hum and vibration from the drivetrain within a certain speed range (e.g. between 80km h and 90km h). Cause of failure:

There are a number of possible reasons for the failure of the drivetrain. Such as wheel imbalance, puncture, longitudinal and transverse runout of the wheel, unbalanced transmission shaft flange, transmission system tension, poor positioning of the transmission shaft and rear axle differential, etc. Solution:

If the fault phenomenon is present over the entire speed range, it may be a bearing damage on the differential. If the faulty Tuanzhou phenomenon is only making noise within a certain speed range, it should be handled in accordance with the TIPS document. The specific steps are as follows:

1 .First, a road test is performed to determine the type of fault symptom. For accurate analysis and location of noise, use the Noise Diagnostic Tool "Steelman Chassis Ear" (SI A).

2.New, balanced Mercedes-Benz genuine wheels (test wheels) are installed on the vehicle and then road tested. 3.

Check the bolting of the propeller shaft: are all the bolts present? Are all bolts the same length?

Do all bolted joints have washers? Check the tightening torque. 4.

The position of the flange of the rear wheel shaft main reducer relative to the transmission shaft changes: the three-arm flange is torsional 120 degrees; The four-arm flange is twisted 90 degrees to collapse. 5.

Reduces the pressure on engine mounts, transmission mounts, exhaust systems, flexible couplings, and intermediate bearings of propeller shafts. Inspect the flexible coupling for cracks and replace it if necessary. Reduce the pressure of the center bearing of the intermediate bearing of the propeller shaft (if the intermediate bearing center bearing must be replaced, the aluminum alloy model should be used), and note that all four wheels of the vehicle are standing on the ground.

In the case of the intermediate bearing bolt is loosened, the vehicle pushes or shakes the propeller shaft forward and backward, and then retightens the bolt with the specified torque (. 6.The tilt angle of the propeller shaft is measured and corrected if necessary.

Summary. Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Shou Bi Ji first determine in what state the vehicle abnormal sound regret socks, in general, the exhaust pipe rubber sleeve is loose, and the bearings of each wheel train are dry and astringent, and then check whether the rubber sleeve cage is damaged.

The 18 Mercedes-Benz C-class body turns right and is stressed by the force of the body, and the body inclination is large. There is a sound.

What accessories have you checked? And then say it.

I looked at the chassis and didn't find anything loose.

There are no flat roads.

There are no flat roads.

It's just that the tilt angle is large. Yes, there is.

If this one is not loose, you also need to check the aspects I just mentioned, and you need to pry it with a crowbar.

The reason why the tilt angle is large is caused by the force.

If your Mercedes Benz makes an abnormal noise when you zoom in**, you can try the following steps:

2.Check your speaker settings: Check that your speaker settings are correct, such as if there is a sound issue caused by misoperation. Try reverting your speaker settings to their default settings and see if the issue resolves.

3.Check your vehicle's power supply: If you're using a car stereo, it's possible that your vehicle's power supply is unstable and you're causing sound problems. You can try to check whether the power supply of the vehicle is normal, including the battery, electrical circuits, etc.

4.Check the sound line: Sometimes the sound line is sold out and the sound is also a problem. You can check if the speaker cable is plugged in, damaged, and needs to be replaced.

5.Contact a professional technician: If none of the above methods can solve the problem, then it is recommended to contact a professional technician for repair. They can conduct a comprehensive inspection of the vehicle's audio system, identify the problem, and give specific solutions.

If there is an abnormal sound in the Mercedes-Benz sound system, it may be due to the following reasons:

1.Poor sound system connection or faulty wiring.

2.The horn or subwoofer is damaged or deteriorated.

3.Amplifier failure.

4.Vehicle vibration causes the sound components to loosen.

In order to solve these problems, you can try the following methods:

1.Check the wiring and connections of the sound system to make sure they are all installed correctly and securely.

2.Inspect horns and subwoofers for damage or age. If yes, they need to be replaced.

3.Check the amplifier for damage. If yes, it needs to be repaired or replaced.

4.Check if the vibrations of the vehicle are causing the sound parts to loosen. If yes, reinstall the speaker parts and make sure they are secure.

If none of the above methods can solve the problem, it is recommended that you consult a professional car audio cavity maintenance personnel for maintenance and maintenance.

If your Mercedes Benz amplified singing voice has an abnormal sound, it could be caused by a number of reasons. Here are some common workarounds:

1.Check that the audio system's cables are not plugged in tightly or aged, and need to be reconnected or replaced.

2.Inspect the interior of the car for loose or detached parts, especially those such as the audio, speakers, and oscillators, which need to be re-fixed or adjusted.

3.Check whether the voltage of the vehicle's battery is normal, if the voltage is too low, it may cause abnormal noise in the audio system.

4.Check if the vehicle's ground wire is properly connected, test it with professional equipment and reconnect it.

5.If the above methods do not solve the problem, it is recommended to send the vehicle to a Mercedes-Benz authorized repair center for inspection and repair.

In general, the abnormal sound of the amplified singing voice of the Mercedes-Benz car may be caused by a variety of reasons, and it is necessary to investigate them one by one and take corresponding solutions. In any case, in order to ensure the proper operation of your vehicle and the safety of your vehicle, it is recommended to choose a professional car repair service.

If there is an abnormal sound in the chassis of the car, it may be caused by the fault of the wheel bearing of the vehicle, if it is this kind of failure, the bucket head Li is easy to make abnormal noise in the chassis when the vehicle is driving, you need to check the wheel bearing, and you must repair the fault or replace the corresponding parts in time.

2. There is an abnormal sound on the chassis of the car, if it occurs when driving on a smooth road, it may be related to the failure of the vehicle's braking system, and the braking system can be checked.

3. When the steering system of the vehicle fails, it is easy to cause the sound of abnormal noise on the chassis of the vehicle, in this case, it is necessary to check the steering system and deal with the fault in time.

4. There is abnormal noise in the chassis of the vehicle, which may also be caused by loose or damaged engine mounts, and the chassis is prone to abnormal noise when starting. If this is caused by this reason, the cause of the failure should also be checked and treated, and if the engine bracket is damaged, it should also be replaced with a new one in time. Causes of abnormal noise in the chassis of the car:

1. The abnormal noise emitted by the vehicle when starting is generally a fault of the suspension system, which may be caused by loose or damaged engine mounts. 2. The abnormal noise emitted by the vehicle when steering may be a fault of the steering system and suspension system. As the vehicle is steering, the suspension system is also involved in the movement due to the tilt of the vehicle that deforms the suspension system.

3. The abnormal noise emitted by the vehicle when the road conditions are good may be the fault of the braking system components. It can be caused by loose or worn brake system components, a brake drum that is out of shape, or a brake disc that is flat. 4. It may also be that there is a problem with the bearing between the dynamic and static connection of the vehicle.

If it is a bearing problem, the driver can distinguish it with a little brake, if the vehicle does not change the brake sound when moving at a constant speed, it is a problem with the bearing. 5. Most of the abnormal noises that occur when the vehicle is driving late when the road conditions are not good are the problems of the suspension system. It can also be caused by a loose braking system.

6. Most of the abnormal noises emitted when the vehicle accelerates, decelerates or stops are caused by the suspension system and braking system. The suspension system emits more friction sounds, to reduce these abnormal noises, the driver needs to pay attention not to drive roughly, try to avoid bumps, when encountering bad road conditions, need to slow down, avoid wading, so as to effectively reduce the abnormal noise of the vehicle chassis.

Mercedes-Benz is a world-famous luxury car brand, however, recently some owners have reported that their Mercedes-Benz engines have abnormal noise problems. So, what is the cause of the abnormal noise of the Mercedes-Benz engine?

First of all, the reason for the abnormal noise of the Mercedes-Benz engine may be that the sail pin is worn or damaged by the parts of the engine due to the long use of the car. For example, wear and tear on components such as crankshafts, connecting rods, piston rings, etc., can cause abnormal engine noises.

Secondly, it may be caused by insufficient oil or poor oil quality. If the engine does not have enough oil, or if the oil quality is not good, it will cause friction between engine components to increase, resulting in abnormal noise.

Third, impurities may appear in the engine air intake system during the driving of the car, such as sand or dust. When impurities in the air intake system are sucked into the engine, it will cause the engine to make abnormal noises.

Finally, it may also be due to the owner's failure to maintain the vehicle in accordance with the regulations during daily use, or the use of unsuitable fuel, resulting in abnormal engine noise. For example, long-term use of low-quality gasoline or diesel can lead to excessive carbon build-up in the components of the engine, which can produce squeak and squeak.

In short, there are many reasons for the abnormal noise of Mercedes-Benz engines, and car owners should pay attention to maintenance during daily use to avoid this problem. If there is an abnormal noise, it should be overhauled and dealt with in time to ensure driving safety.
