Double rocker shock absorbing squeak? What s going on with the abnormal sound of the rear shock abso

The double rocker shock absorption squeak should actually be checked.

In addition to bearing the weight of the vehicle itself and the people themselves, the shock absorber also has to work continuously in the process to reduce the bumps on the road. Hundreds of thousands of compressions over a lifetime inevitably have an impact on their lifespan and are accompanied by damage.

So what kind of situation should you pay attention to when the shock absorber occurs?

1. Oil leakage from shock absorber.

The most common problem, which is also the most intuitive to see, is the oil leakage of the shock absorber. After the oil leakage of the shock absorber, the oil pressure inside the entire sleeve decreases, the shock absorption effect will be weakened, and the abnormal sound will also occur due to the oil leakage. Such abnormal sounds are mostly the "duangduang" sound of hard objects hitting hard objects or the "squeak" sound of friction.

The judgment method is also relatively simple, that is, observe the shock absorber of the vehicle without washing the car to see if there is sludge and oil stain, if so, then you can conclude that the shock absorber is leaking. Minor oil leakage can be ignored and generally will not cause abnormal noise, but if there is a serious oil leak, it needs to be replaced in time to reduce potential safety hazards.

2. The shock absorber is installed incorrectly.

Some repair shops are not careful in installation, and the fixing nut is not fixed firmly during installation, or the fixing nut is loose due to long-term vibration in the driving. It will cause the shock absorption to make an abnormal sound, and you only need to tighten the fixing nut, and it is best to let the repair shop master check it once.

3. The shock absorber is deformed.

After the shock absorber encounters an impact, it deforms and makes an abnormal sound. Common shock absorber piston rods, cylinder barrels or oil reservoir deformations, piston rod hairpins, should go to the repair shop to check and replace.

4. The shock absorber "sizzles, sizzles" abnormal sound.

Because of the sound of friction between the piston rod and the oil seal of the shock absorber, it can be solved by touching a little butter where the piston rod and the oil seal rub (the butter of *** point). There is very little butter in the newly installed shock bearing, and the cold butter is frozen in winter, and it will produce abnormal noise when it is opened to an uneven place, and the solution is to add as much butter as possible to the plane bearing to remove the shock absorber.

5. Abnormal noise of other components.

The abnormal sound of the shock absorber is actually very easy to judge, but there are some black pots with abnormal noise that often need the shock absorber to back.

Severe wear on the steering ball joint is one of them. The steering ball joint is a part of the steering system that is more prone to wear and tear, and is more likely to appear on some older vehicles.

The steering header can also make a squeak when it is worn, and many irresponsible repair shops will ask for the shock absorber to be replaced. And because the steering ball head is relatively close to the shock absorber, it is indeed easy to be "misdiagnosed".

The other is that the top rubber or steering tie rod ball joint is loose, also called when there is a problem with the plane bearing, there will be an abnormal sound when the steering is played, a bit like the sound of tire rubber grinding the ground, after the vehicle is lifted off, the steering tire, the bearing will emit a regular "bar" sound. This is basically the sound of the balls inside the bearing. Such a sound is more pronounced when passing through speed bumps or over bumpy roads, and it is also easy to be "misdiagnosed" as a shock absorber failure.

The cause of the abnormal noise of the shock absorber is the abnormal noise caused by oil leakage or bending of the shock absorber itself, which can be solved by directly replacing a new shock absorber; The damping pressure bearing is aging or wearing abnormally, and this situation can be solved by direct replacement or lubrication.

The reasons for the abnormal sound of the shock absorber are: oil leakage or bending of the shock absorber itself, aging or abnormal wear of the shock absorber pressure bearing, deformation of the shock absorbing spring, damage to the rubber sleeve of the balance bar, and clearance of the connecting ball joint.

The abnormal noise of the shock absorber means that the rubber pad of your shock absorber is worn out and needs to be replaced.

If the shock absorber is leaking or bending, it can be replaced directly;

If the damping pressure bearing is caused by aging or abnormal wear, it should be replaced directly.

If the shock absorber spring is deformed, it can be replaced directly.

It's still a new car, and it's in the warranty, so if something goes wrong, go to the 4S store and let them be rectified. This is free to claim. Generally, there is not much time for a new car to be launched, and some problems are really uncertain.

If there is an abnormal noise when the car passes through a bumpy road, is the shock absorber malfunctioning? Detailed analysis of auto repair mechanics!

Cars provide great convenience for everyone's travel, and everyone drives out more and more frequently. However, after the car has been driven for a long time, various problems will occur, such as abnormal noise of shock absorbers. Next, I will give you a detailed introduction to what is going on with the abnormal noise of automobile shock absorbers.

1. It may be because the damping pressure bearing is aging. When the pressure bearing is aging and wears severely, it is very easy to make abnormal noise, and it needs to be lubricated in time, or replaced with a new shock-absorbing pressure bearing.

2. It may be because the shock absorber spring is deformed. When the shock absorber spring is deformed, there is no way to return to its original state, and then there will be abnormal noise. In this case, it is necessary to replace the shock absorber spring with a new one in time.

3. It may be because the wheel bearing is damaged. If the wheel bearings are damaged, then turning the steering wheel at low speeds will make a "squeak" noise.

The above is the reason for the abnormal noise of the car shock absorber, when the vehicle shock absorber has an abnormal noise, the owner had better go to the 4S shop as soon as possible for inspection, and carry out the corresponding repair or replacement, so as not to affect the normal operation of the car.

If it's just an over-deceleration with a fluttering sound, you can check for oil leaks (grease stains or drips) before driving. There are many reasons for the abnormal noise of the shock absorber, the common ones are: oil leakage, (some shock absorbers are inflated, if it is an air leak, it is not as light as the abnormal noise you described), welding and desoldering (this kind of sound will always have a sound), spring abnormal noise, valve system failure and so on.

I went to the pit and looked at it, and there shouldn't be any major problems.

Automobile shock absorption abnormal noise, when the winter weather is cold, the shock absorber is relatively viscous, when the car drives over the uneven road shock absorber function, at this time because the oil is too thick, the lubrication is not good will make abnormal noise. When the car is hot or in summer, the shock absorber oil is relatively thin, and when passing over the uneven area, the oil lubrication reducer is better, so it will not make a sound.

It's the problem with my car.

It's already there, I don't know if the landlord found it, this situation is only in the cool car, especially in winter, there will be a sound, asked the expert is.

Shock absorber. A voice from above, suggesting that LZ be at it, more than one expert said that even if the decisive time is changed, there will be.

The reasons for the abnormal noise of the broken shock absorber of the car: 1. If the shock absorber of the car is damaged, first of all, you can try that the shock absorption effect of the vehicle becomes worse, and the amplitude of the body shaking becomes larger, and secondly, you can hear the abnormal noise, and finally you may see oil stains; 2. Oil leakage from shock absorber. The normal outer surface of the shock absorber is:

The reason why the shock absorber of the car is broken and the abnormal noise:

1. If the shock absorber of the car is damaged, first of all, you can try that the shock absorption effect of the vehicle becomes worse, and the amplitude of the body shaking becomes larger, and secondly, you can hear abnormal noises, and finally you may see oil stains;

2. Oil leakage from shock absorber. The outer surface of the normal shock absorber is dry and clean, if there is oil seeping out, it means that the hydraulic oil inside the shock absorber escapes from the upper part of the piston rod, and the shock absorber has basically failed in this case;

3. When the car crosses a bumpy road or speed bump, a certain wheel makes a "clang" sound, indicating that the shock absorber on the wheel has a poor damping effect or fails; When the car is cornering, it obviously feels that the body roll increases, and even skidding will occur in serious cases, which is mainly because the damping force of the shock absorber is too small and cannot effectively suppress the compression of the spring;

4. After the car is driving in rough road conditions for a period of time, touch the shock absorber shell with your hand to feel the temperature of the shock absorber, under normal circumstances, the shock absorber shell is warm, if a shock absorber shell is cold, it means that the shock absorber has been damaged;

5. When the car is stopped, when the corner of the car body is pressed down and released, the body will be stable under the spring force, and if it tends to stabilize soon after the car, the shock absorber is good; If it stops after repeating ** several times, it means that the damping effect of the shock absorber is a little poor. What information should I bring to the inspection? What information do you need to bring to the 2019 car inspection?

1.Owner's ID card. If it is done by someone else, only the ID card of the **person needs to be provided; 2. Motor vehicle driver's license and copy, body ** copy; 3.

A copy of the compulsory insurance policy within the validity period, expired or uninsured, will not be accepted. or the original certificate of insurance of compulsory traffic insurance can also be used; 4.Cash; 5.

Because it is a car inspection, the car must be present. If the annual inspection is overdue, the public security traffic management integrated application platform will automatically display the vehicle status as overdue and uninspected. In this case, if the vehicle continues to drive on the road and is seized by the traffic police, in addition to temporarily impounding the motor vehicle, the driver will be fined 200 yuan and 3 points will be deducted; In the event of a traffic accident or loss, the insurance company may refuse to pay compensation, and all losses shall be borne by the owner himself.

Precautions for annual inspection of automobiles 1. Since the insurance documents need to be provided during the vehicle inspection, and the insurance documents must be the original within the validity period to ensure that the vehicle can be successfully inspected, the original insurance policy within the validity period needs to be carried during the vehicle inspection, for the purpose of compulsory insurance. 2.

Before the vehicle is inspected, the vehicle owner should ask whether the vehicle has violated the law. If you do not deal with the regulations, even if the vehicle can pass tests such as exhaust gases and appearance, check 3. Some car owners modify or paste some interesting vehicle logos for personal interest, and it is recommended that the vehicle be restored to the same as the ** on the driving license before the annual inspection.

The shock absorber is broken, what's the abnormal sound @2019

The reason for the abnormal noise of automobile rock imitation shock absorption:

1.Oil leakage from the shock absorber. When the shock absorber leaks, the inside of the shock absorber cannot be effectively lubricated, so there will be a lot of friction noise when working;

Solution: Replace the shock absorbers.

2.Aging of shock absorber top seat plane bearings or lack of oil. Aircraft bearings are located in the cabin. Open the hood, press the body, and listen for any abnormal noise coming from the shock absorber top seat. If so, it is likely that the aircraft bearings are aging.

Solution: Replace the shock absorber top seat plane bearing. Coarse.

3.The shock absorber spring is deformed or broken. In this case, the shock absorber springs can only be replaced in their entirety.

Solution: Go to the maintenance mechanism to replace the shock absorber spring.

4.Many reasons, such as damage to the damper in the shock absorber, damage to the rubber on the top of the shock absorber, etc., may cause the shock absorber to make abnormal noise;

Solution: Go to the 4S shop to replace the shock absorber and the top glue of the shock absorber.

5.Problems of rubber parts such as balance bar lifting lugs and rubber sleeves of support arms will also produce abnormal noises after aging;

Solution: Replace the rubber sleeve of the balance bar lifting lug and the support arm.

6.The shock absorber oil in the shock absorber has a large hail difference, which leads to excessive resistance of the shock absorber in motion, which leads to this phenomenon.

Solution: Change the shock absorber oil.
