The chassis gurgled and gurgled for what reason

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.

Which distribution bolt of the caliper is loose, you want to change it, you can buy it yourself, you can change it in four s, you can hear it when you knock on the tire with a hammer, the change is very fast, and the rubber will sound when it ages.

Various possible causes of abnormal noise in the chassis of a car.

1. Abnormal sound of disc brakes.

Features: When the vehicle is driving at a low speed on a flat road, it makes an intermittent and irregular "rattling" sound on the axle.

Reason: This is due to the damage, deformation and falling off of the brake shoe support plate, vibration damping spring plate or guide plate of the disc brake, which increases the gap between the brake shoe and the brake caliper support frame, and makes a sound when it hits each other. You can go to the repair station to repair the deformed parts and replace the parts that have fallen off.

Second, the front suspension ball head abnormal sound.

Features: When the vehicle is driving on the undulating road surface in a low-speed gear, the front axle part emits an uninterrupted "click" sound, the worse the road quality, the louder the sound, and the sound intensifies with the increase of speed.

Reason: The gap between the ball head and the ball head seat becomes larger, and the looseness is severe. Because the ball head seat is a sealed structure and cannot be removed, it can only be replaced at the repair station in this case.

Three. Abnormal noise of the front wheel shock absorber.

Features: On flat roads, you can hear the "cooing" of the front of the vehicle, which is intensified when turning sharp corners.

Cause: Vehicles are often driven on bad roads and are not properly maintained, resulting in oil leakage and damage to shock absorbers. Depending on the severity of the damage, it will need to be repaired or replaced.

Fourth, the transmission shaft universal joint abnormal sound.

Features: If the front drive constant velocity joint is faulty, in the vehicle in motion, especially when cornering or accelerating sharply.

Reason: The abnormal sound of the constant velocity gimbal is due to the excessive clearance of the gimbal or the issuance of cards. The main reason for the abnormal sound of the universal cross shaft is that there is no lubrication device or the maintenance is not timely. In this case, you should go to the workshop to apply grease or repair.

The following are the specific causes of chassis noise on slightly bumpy roads:

1. Disc brake failure: Due to the damage and deformation of the brake shoe support plate of the disc brake, the gap between the brake shoe and the brake caliper support frame increases.

2. Front suspension ball joint failure: The gap between the ball head and the ball head seat becomes larger, and the looseness is serious.

3. Front wheel shock absorber failure: The vehicle is usually driven on bad roads and is not properly maintained, resulting in oil leakage and damage to the shock absorber.

The chassis refers to the combination of four parts of the transmission system, the driving system, the steering system and the brake system on the car, which supports and installs the automobile engine and its various components and assemblies to form the overall shape of the car, bear the engine power, and ensure normal driving.

The function of the chassis is to support and install the automobile engine and its various parts and assemblies, form the overall shape of the car, and accept the power of the engine, so that the car can move and ensure normal driving. At the same time, a good chassis can ensure the safety of the driver's life.

The chassis is composed of four parts: transmission system, driving system, steering system and brake system.

The drive train is mainly composed of clutch, transmission, universal joint, drive shaft and drive axle.

Clutch: Its function is to make the power of the engine and the transmission device smoothly engaged or temporarily separated, so as to facilitate the driver to start, stop, shift and other operations of the car.

Transmission: It is composed of transmission shell, transmission cover, first shaft, second shaft, intermediate shaft, reverse shaft, gear, bearing, control mechanism and other parts, which are used for automobile transmission and variable output torque.

The driving system consists of the frame, axles, suspension and wheels. The basic function is to support the quality of the whole car and ensure the driving of the car.

Leaf Springs & Shock Absorbers: The role of leaf springs is to maintain an elastic connection between the frame and body and the wheels or axles. The function of the shock absorber is to cushion the vibration when the car is subjected to vibration impact. The shock absorber is used in parallel with the leaf springs.

Hello, happy to answer your questions.

Hello. I am your exclusive technician, attentive, careful, attentive to answer your questions, I hope this service can help you. The car is slightly bumpy and the road surface is rumbling, and there are several times for the first reason of these reasons, there is a problem with the shock absorber, which causes a gurgling sound.

In the second case, you need to check the top glue for shock absorption. If there is a phenomenon of loosening or aging, this phenomenon will also occur, and the third phenomenon is the rubber pier of the balance bar. There is a looseness, and there is a gurgling sound.

These three situations need to be checked. The ** of the shock absorber is slightly more expensive than other pieces. It doesn't cost much to replace the pile, from dozens of dollars to more than 100 depending on the model.

Ask a question, check the chassis without a problem.

Focus on the three things I said.

Question: There is no oil leakage from the shock absorption.

No oil leakage means that he is not bad, and it will also have abnormal noises.

Question: The chassis was checked yesterday, and the lower arm ball head was replaced, and it was still loud to make sure that the chassis was not loose, so I checked the shock absorption and the top.

Top glue questions. Okay, if you feel that it is helpful to you, please give a like after the problem is over, and the platform will send you a coupon that you can use next time.

Ask a good question. Hmmm, if I can help you, please give me a thumbs up Thank you!

1. Constant velocity universal joint abnormal sound: Constant velocity universal joint is commonly known as ball cage, and its main function is to transmit power and complete steering. If the constant velocity universal joint is seriously worn, and the vehicle turns while driving, there is an abnormal sound similar to "rattle and rattle", you only need to confirm which side the abnormal noise is, and then replace the constant velocity universal joint to solve it.

2. Abnormal sound of wheel bearing: The function of wheel bearing is to connect the vehicle and the tire. No matter how big the tire is, the connection between the vehicle and the tire is by a small wheel bearing, if the wheel bearing is damaged, it will cause the tire to deviate, or even the tire to fall off.

When the vehicle is driving, it emits a continuous abnormal sound similar to "buzzing", which is the alarm of the wheel bearing, and the faster the speed, the stronger the sound, if it is slightly damaged, there will be an abnormal sound when the direction is generally tapped.

3. Abnormal sound of exhaust pipe: abnormal sound of exhaust pipe is generally caused by rupture or leakage of exhaust pipe, and there will be "poof" noise after the vehicle starts. It may also be caused by the damage or blockage of the three-way catalytic converter, which is used to reduce the noise while purifying the exhaust gas.

The above is the introduction of the abnormal sound of the car chassis, I hope it will help you.

Causes and solutions of car chassis rattling:

1.Disc brake abnormal sound:

Reason: This is because the brake shoe support plate, shock absorbing spring or guide plate of the disc brake is damaged, deformed and falling off, which increases the gap between the brake shoe and the caliper support frame, and makes a sound when colliding with each other.

Solution: You can go to the repair station to repair the deformed parts and replace the parts that have been removed.

2.Front suspension ball head abnormal sound:

Reason: The gap between the ball head and the ball head seat becomes larger, and the loosening is serious. Because the ball and socket are sealed and cannot be disassembled.

Solution: This situation can only be replaced by going to the repair station.

3.Abnormal sound of the front wheel shock absorber:

Reason: The vehicle usually drives in poor road conditions and improper maintenance, resulting in oil leakage and damage to the shock absorber.

Solution: This situation should be repaired or replaced depending on the severity of the damage.

4.Abnormal sound of the driveshaft universal joint: If the front drive constant velocity universal joint is faulty, it will be in motion, especially when turning or accelerating sharply.

Reason: The abnormal sound of the constant velocity universal joint is caused by too large a gap or a hairpin. The main reason for the abnormal sound of the cardan cross shaft is that there is no lubrication device or the maintenance is not timely.

Solution: In this case, you should go to the workshop to apply grease or repair.
