What are the symptoms of a broken shock absorber in a car?

If the shock absorber of the car is broken, there will be the following symptoms:

1. Oil leakage: When it is found that there is oil leakage outside the shock absorber, it means that the shock absorber has been damaged.

2. Loose chassis: When the vehicle is driving to a bumpy road, if it is found that the body attitude is too bumpy and swaying, it is generally a problem with the shock absorber.

3. Abnormal noise: If the shock absorber makes an abnormal noise when the vehicle is driving on a bumpy road, it is very likely that the shock absorber is the cause of damage.

4. Uneven tire wear: When the shock absorber is broken, the wheel will vibrate unevenly during driving. Causes the wheels to roll and other phenomena, so that the tire part that touches the ground is seriously worn, and the untouched part is not affected, and over time it forms an uneven shape of wear, and the vehicle is unstable, and it also increases the bump discomfort.

Symptoms of broken shock absorbers: the car will shake up and down if the road surface is slightly uneven. When crossing a bumpy road, it used to stop after one or two ups and downs, but now it takes three or four times to stop, and the amplitude increases, which is a typical symptom of a broken shock absorber.

The shock absorber usually does not need maintenance, only if it is broken, it needs to be replaced, and there are two common types of damage.

The car stops after driving 10km on the road surface with poor road conditions, and touches the shock absorber shell with your hands, if it is not hot enough, it means that there is no resistance inside the shock absorber, and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then carry out the test, if the shell is hot, it is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber has failed; Press the bumper hard, then release, if the car has 2 or 3 jumps, then the shock absorber is working well; When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber; Remove the shock absorber to stand upright, and clamp the lower end connecting ring on the vice, pull and press the damping rod several times, at this time there should be stable resistance, the resistance to pull up should be greater than the resistance when pressing down, if the resistance is unstable or no resistance, it may be that the shock absorber is short of oil or the valve parts are damaged, and the parts should be repaired or replaced.

After determining that the shock absorber is faulty or failing, you should first check the shock absorber for oil leakage or signs of old oil leakage.

The oil seal gasket and sealing washer are broken and damaged, and the oil storage cylinder head nut is loose. It may be that the oil seal and sealing gasket are damaged and failed, and the new seal should be replaced. If the oil leakage still cannot be eliminated, the shock absorber should be pulled out, if you feel a hairpin or a difference in weight, further check whether the gap between the piston and the cylinder barrel is too large, whether the piston connecting rod of the shock absorber is bent, and whether the piston connecting rod surface and the cylinder barrel are scratched or pulled marks.

If the shock absorber of the car is broken, the shock absorption effect will be worse, and the shock absorber will also make abnormal noises when passing over speed bumps or bumpy roads. Some cars will have oil leakage after the shock absorber is broken.

The shock absorber of the car is also a wearable part, and some cars need to replace the shock absorber after a long time.

If the shock absorbers of the riders are broken, it is recommended to replace all the shock absorbers on all four wheels.

When buying shock absorbers, you need to buy original parts, or buy shock absorbers made by big brands.

Many riders feel that the car is not as good as when the new car is first bought after a few years, but this is actually a normal phenomenon, because many parts on the chassis of the car will age after a few years of driving.

There are a lot of rubber bushings on the chassis, and these rubber products will age with the increase of use.

After the rubber bushing is aged, the space of many parts on the chassis of the car will become larger, so that the chassis will be loose when the car is driven.

If you want to restore the texture of the old car when you first bought it, you can replace all the aging rubber bushings on the chassis, or you can replace all four shock absorbers.

When replacing the rubber bushing, you must also choose the original accessories, and you can also buy the accessories produced by big brand manufacturers.

Hello friend, the shock absorber is broken, that is, it has no shock absorption, when encountering potholes, the vehicle will be particularly bumpy, please repair or replace it in time, thank you.

The performance of the broken shock absorber: when the car is on a bumpy road, the shock absorber makes a "rattle" or "squeak" sound when the bump occurs, and when the car drives slowly and brakes urgently, if the car vibrates more violently, these phenomena indicate that the shock absorber is broken, and one of the most important manifestations is the shock absorber oil leakage, which also indicates that the shock absorber is broken.

After the shock absorber is broken, the shock absorption effect will definitely become bad, and the bike may be more bumpy and unstable when driving.

If the shock absorber of the car is broken, it must be that the driver and passengers will feel very obvious when they cross the pothole.

The most obvious symptom of a broken car shock absorber is that it is bumpy on the road, and the vehicle will make abnormal noises when crossing potholes, and there will be oil leakage.

The direction deviates from the body and the body is uneven. The car shakes. Unable to drive normally.

What are the symptoms of a broken shock absorber in a car, and the shock absorber is particularly uncomfortable to sit on.

1. Make the car stop after driving 10 kilometers on the road surface with poor road conditions, touch the shock absorber shell with your hands, if it is not hot enough, it means that there is no resistance inside the DAO shock absorber, and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then test, if the shell is hot, it is a lack of oil inside the shock absorber, and enough oil should be added, otherwise, the shock absorber fails.

2. Press the bumper hard, and then release, if the car jumps no more than once or twice, it means that the shock absorber is working well. If you keep nodding your head up and down and look elastic, it's broken.

3. When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber.

4. Remove the shock absorber to stand upright, and clamp the lower end connecting ring on the vice, and pull and compress the shock absorber rod several times, at this time there should be stable resistance, and the resistance to pull up and restore should be greater than the resistance when pressing down, if the resistance is unstable or there is no resistance, it may be that the shock absorber is lacking oil inside or the valve parts are damaged, and the parts should be repaired or replaced.

An oil leak is considered bad.

2. The car runs on a bumpy road and makes a clattering sound.

You're all right, you're all amazing.

What are the symptoms of a broken shock absorber in a car? The automobile shock absorber is actually an assembly, so if you want to judge whether the shock absorber is damaged, you must start from each component that makes up the shock absorber assembly, so as to determine the cause of the failure. Today's automotive shock absorbers were originally designed by American engineer MacPherson, who used the same steering geometry as the traditional upper and lower control arms to invent a new type of suspension, using fewer parts, and can transmit vibrations directly to the springs without first going through the control arms, all of which bring a more comfortable ride and driving safety, the only requirement is that there must be a frame upper body and high-strength fenders.

"Shock absorber" consists of: shock absorber top fixing screw, plane bearing, top rubber, shock absorber buffer block, spring, shock absorber.

Determine the symptoms of a broken shock absorber:

When the road is tested, the vehicle through the pothole road makes a "knock knock" sound, at this time there are two situations, one is caused by the loosening of the ball joint of the vehicle balance bar, and the other is the failure of the shock absorber assembly. If the abnormal noise does not disappear, it proves that the shock absorber is faulty, otherwise it is the balance rod ball joint fault.

1. Plane bearing and top angle are damaged. When the steering wheel rotates left and right, there is a "cluck" sound, put your hand on the shock absorber spring and turn the steering wheel left and right, the spring has an obvious sense of vibration, this time proves that the plane bearing and top angle need to be replaced.

2. The shock absorber buffer block is damaged. One of the functions of the buffer block is to maintain the cleanliness of the shock absorber telescopic rod and avoid fine sand and gravel scratching the sealing ring resulting in oil leakage of the shock absorber; The second is to cushion the oil leakage caused by the extreme expansion and contraction of the shock absorber under high pressure pressureThe seemingly simple buffer block can effectively extend the service life of the shock absorber, and it must be replaced if it is damaged by aging for a long time.

3. Spring failure. The shock absorber spring will not have any problems under normal circumstances, and the vehicle will tell the spring to break if it is too strong when driving over a pothole, but I have only encountered this situation once, which is more extreme and basically does not occur.

4. Oil leakage and deformation of shock absorber. The oil leakage is easy to judge, as long as there are oil stains on the column wall of the shock absorber, if there is 100% damage to the shock absorber; To determine whether the shock absorber is deformed, you need to lift the vehicle, and then fall back to the original height, observe the camber change of the tire, if the camber angle is inconsistent, it proves that the shock absorber is deformed and bent.

Summarize and judge whether the shock absorber is damaged, from the balance bar ball joint, plane bearing, top rubber, shock absorber buffer block, spring, shock absorber these aspects one by one, basically the shock absorber damage is the most obvious is that there is abnormal noise during driving, and oil leakage is the majority.

The symptoms of a broken shock absorber include: oil leakage from the shock absorber; When a car is crossing a bumpy road or speed bump, a "clang" sound from one of the wheels indicates that the shock absorber may have been damaged.

The symptom of a broken shock absorber is that the uneven road surface will feel very hard and inelastic during driving, and there will be abnormal noises on the side of the tires.

The shock absorber will make a noise, which can be felt under normal circumstances, and the car will also bump around because of the uneven road surface.

When the car is driving to a bumpy road, the shock absorber will make an abnormal sound. When the shock absorber is damaged, there is also an oil leak, and if both of these are the case with the car, it is a shock absorber that is damaged.

It is driving on the road and encountering some small obstacles, you will find that the vehicle is particularly bumpy. Usually it's the shock absorber that's broken.

Two days ago, I changed the shock absorber, and I always felt that the repair shop was lying to me, but now that I look at it, it seems that there is an abnormal noise.

The performance of the broken shock absorber of the car is as follows: 1. When driving on the road surface with bad road conditions, if you feel that the vibration of the car body is large, it is easy to get motion sickness (referring to individual people). This means that the shock absorption of the car does not work, replace or check whether there are other parts of the reason; 2. When the car is driving, due to bumps, the tire grip is poor, the body is constantly shaking up and down, and the braking distance is extended during emergency braking; 3. During the driving of the car, the noise is large, which indicates that there is a problem with the car shock absorber, and you can properly check whether there is less lubricating oil.

If it still does not work, replace or repair; 4. Press the car bumper hard and then release it. If the continuous up and down vibration of the car cannot be stopped, it means that the shock absorber of the car has failed; 5. If there is a problem with the automobile shock absorber, it is not necessary to replace it, unless the shock absorber is deformed or broken.

1. Riding experience: When the shock absorber is broken and fails, the vehicle will inevitably produce bumps in the body when passing through the bumpy road, and the amplitude of vibration is large, which directly reduces the comfort of the passengers in the car with rubber socks.

2. Abnormal temperature: The shock absorber converts the body vibration and the mechanical energy of the wheels into heat energy, and dissipates it with the heat driving, so as to achieve the purpose of attenuation. If you feel the temperature of the shock absorber shell with your hands after driving on a rough road, and find that the shell is warm, it means normal, if you feel cold when you touch a certain shell, it means that the shock absorber has been damaged.

3. Oil leakage: When the shock absorber is working, the oil mist evaporated by the high-temperature oil is often attached to the cylinder wall, and with the driving of the vehicle, the dust brought up by the wheels will be adhered to the oil mist to form a layer of oil sludge, which is a normal situation. However, if the hydraulic oil inside the shock absorber does not escape from the piston rod, or there are oil stains or oil droplets on the cylinder wall and lower lifting ring of the shock absorber, it means that the shock absorber has leaked and failed.

4. Abnormal noise: If a shock absorber is damaged, the corresponding wheel is equivalent to no shock absorber, which will lead to a greatly reduced shock absorption effect, and when the vehicle is driving on a bumpy road, it will emit a "bang" abnormal sound. At the same time, the adhesion between the wheel and the ground will also be reduced, when the vehicle is cornering, the wheel will leave the ground, at this time it can be clearly felt that the body roll is intensified, and there will be a danger of sliding or even out of control in serious cases, which is mainly because the shock absorber damping is too small to effectively suppress the compression of the spring.

Therefore, when the shock absorber fails, especially when cornering, the driving speed of the vehicle must be reduced to ensure driving safety, and then repair it in time.

Automobile shock absorber is a very important part of the suspension system, its main role is to inhibit the spring suction such as hail vibration deformation and spring **, while absorbing the impact force from the road surface, so the car shock absorber is broken to check or replace in time.
