The left side of the car squeaks to the speed bump, is it a shock problem?

The left side of the car to the speed bump squeaks, is it a shock absorption problem: in general, the "abnormal noise" should be called the suspension system abnormal noise, mostly from: a, the chassis connecting parts are loose, due to a long time and fall off or the tightness is too large (loose), the gap is too large and other reasons can cause abnormal noise.

b. The connecting ball (connector) is loose, the balance rod (sleeve) is deformed, or the buffer glue (block) is aging and falling off. c. Abnormal tire pressure (too high or too low), dynamic balance, etc., may affect the "abnormal noise", handling performance or tire noise from itself. d. The "sound" from the shock absorber, in general, the shock absorber itself has very little abnormal noise, only when the shock absorber function fails, the condition deteriorates, the internal parts fall off and loose, the shock absorber lifting eye rubber sleeve is loose, the internal oil shortage (hydraulic cylinder type) or oil leakage can cause abnormal noise.

However, the "silky" sound generated by the oil when the shock absorber piston moves up and down should not be regarded as an "abnormal sound". e. The buffer rubber block of other relevant parts, the "abnormal noise" caused by the swing (runout) rate of high-speed dynamic balance parts f. Human factors (operational errors), such as unreasonable assembly, different sizes of strength (tightness) during assembly, missing (missing) parts, etc.

Hello! You're right, it's probably a shock absorber problem.

It shouldn't be that a large part of the cars you pass by will have a sound.

Hello, it may be a shock absorption problem, and then check whether there is a problem with the balance bar upright.

This sound should be balanced in the front suspension.

The sound of the cushion sleeve on the rod holder rubbing against the balance bar. If this sound only happens in the winter when the temperature is low, there is nothing wrong with it.

The part pointed to by the red arrow in the picture below is the balance bar fixing sleeve. The balance bar is connected to the shock absorber by the balance pull rod, and when the balance bar is pulled during the shock absorption movement, the balance bar will produce a torsional force, and there will be a slight twist, and at this time, the balance bar is also stressed by a large force, and the friction with the rubber makes a creaking sound. Especially in winter, when the temperature is low, the rubber will harden to a certain extent, and hard grinding will produce this creaking sound.

Focus on checking whether the shock absorbing top glue, suspension ball joint, and torsion rod rubber sleeve are damaged.

The rubber sleeve is broken, and the car is swaying back and forth when it accelerates and decelerates; As for the ball head, the top glue is damaged, and it is vibrating up and down.

The torsion rubber sleeve is damaged, and when turning, it will creak and creak.

The car always has an abnormal sound, especially when it crosses the speed bump, check whether the car suspension system, exhaust pipe, etc. have loose fixing screws, and it is best to go to the four S shop to overhaul some.

Maybe the hydraulic oil is leaking, overhaul it, it may have to be replaced!

The creak of the shock absorber before passing the speed bump may be the oil leakage of the shock absorber due to early failure, the deformation or fracture of the shock absorber spring, the aging of the plane bearing of the shock absorber top seat or lack of oil.

When the exhaust gas is discharged from the exhaust pipe, it has a certain pressure, and when the exhaust pipe is poorly sealed, the exhaust gas will leak out of the gap, and the exhaust gas will leak when it passes through the gap at high speed. Secondly, if your car is equipped with air suspension, there will also be air leakage when raising or lowering the chassis, which is normal, and there is no need to repair the simple and simple reason. Finally, there will be a similar sound of car tire leakage, if there is a flat air at the same time the tire pressure is abnormal, it indicates that the tire is a problem.

Inspect the car

The parts connected between the shock absorber and the body are cushioned rubber, which can protect the body and improve the ride comfort of the car. When replacing the cushion rubber, it is necessary to disassemble and assemble the shock absorber, and when installing the shock absorber, be sure to use a special torque wrench to tighten the screws, and be sure to tighten the screws in the specified order.

After installing the shock absorbers, be sure to re-align the four wheels of the car, which can prevent the car from mistracking and tire wear. If the car deviates, it will affect the car's handling and driving stability. If the rubber product is aged, it will become hard, so that the car will make abnormal noises when the cushion rubber is squeezed when passing through some bumpy roads or speed bumps.

If the chassis rattles when the head of the Fang clan or the general direction is started, it should be a steering cage failure, mostly due to the damage of the cage dust jacket, resulting in impurities entering, and the result is poor lubrication and excessive wear for a long time. At this time, there will be an abnormal noise. Always pay attention to check the dust jacket when maintaining the car, and replace it immediately if it is damaged.

There is a lot of butter in the cage, and as long as the dust jacket is not broken, it is still very durable.

If there is an abnormal sound in the direction of hitting at low speed or stationary state, accompanied by the situation of directional weight, it may be a problem with the plane bearing above the shock absorber, which is to achieve the steering effect.

The reasons why a car squeaks when passing through speed bumps are:

1.aging of the ball head of the balance bar boom;

Solution: Replace the ball head of the boom with a new equalizer bar;

2.The ball joint clearance of the steering rod is too large;

Solution: Check whether the ball joint clearance of the steering rod is too large;

3.The cushioning parts on the chassis are damaged.

Solution: Replace the buffer assembly on the new chassis.

4.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: You can choose to replace the oil seal of the shock absorber;

5.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 the shock absorber top seat to make an abnormal noise. If so, it is likely that the aircraft bearings are aging.

Solution: The shock absorber is seriously aged, and the entire shock absorber can be replaced if necessary;

6.The shock absorber spring is deformed or broken.

Solution: In this case, the shock absorber spring can only be replaced as a whole.

Precautions when passing through speed bumps: Decelerate before passing through speed bumps, and pass slowly through the two wheels vertically. This method allows the left and right wheels to shrink at the same time. The force from the ground is divided in half by the springs and shock absorbers of the two wheels, and the even force can reduce the damage to the car.

Speed bumps, also known as speed bumps, are special traffic safety devices installed on highways to reduce the speed of motor vehicles and non-motor vehicles.

The abnormal noise of the car will indeed make the car buyers very uncomfortable in the whole process of driving, in addition to the abnormal noise of the interior of the car, the abnormal noise of the car chassis is also very common. Many car buyers show that their cars crunch over speed bumps, so what is the reason for the abnormal noise of the car chassis? The following will analyze for us a number of commonly used causes of abnormal noise in the automobile chassis.

The most common cause of equipment failure when a car creaks over a speed bump:

1. If the damping oil of the shock absorber of the car leaks or the liquid level gauge is too low, the shock absorber will not be fully moistened, and the shock absorber will make abnormal noise when the road is shaking;

2. If the gap between the front horn support point of the car is too large, similar abnormal noise will occur;

3. The last common reason is due to the embrittlement of the steering with the destruction of the rock rubber pad and the cage, and this kind of situation can only be completely solved by dismantling and replacing the new steering pad and cage.

Rear tire squeak solution over speed bumps.

If it is due to the leakage of the damping oil of the shock absorber, the skeleton seal of the shock absorber must be checked, if the shock absorber skeleton seal is damaged, it must be disassembled and replaced and oiled again, and all the shock absorbers can be dismantled and replaced if necessary. If the gap between the front horn support points of the car is too large, the horn gap can also be adjusted to deal with the problem of abnormal noise. Steering pads and cage embrittlement can only be handled by replacing them with new ones.

Usually, when you cross the residual positive speed belt, you should pay attention to slowing down and driving slowly to prevent a great impact on the suspension system.

Why does it make an abnormal noise when I turn the steering wheel in place?

The abnormal sound from the destruction of the rebound torsion spring of the steering power switch is also the sound of the automobile department. The second condition may be due to the sound of the azimuth pole dust jacket. Whether you stay still or drive just turn the steering wheel will hear, and the sound is coming from under the steering wheel of the car, you need to check the azimuth column dust jacket, once the azimuth column dust jacket lacks moisturization will cause a dry friction sound, you only need to apply some unsalted butter in the dust jacket This sound will subside.
