Please teach the steering wheel idle shake problem

The steering wheel shakes when the car is idling, which is very common, and some car owners can feel a strong steering wheel shake when driving the car at high speeds, when the speed reaches 80-100km h or more. In this case, most of the problems occur in the tires of the car, because the uneven distribution of the mass of the whole part of the tire will cause the wheels to rotate at high speed, and there will be a dynamic imbalance state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires must be replaced.

In addition to the tires of the car, there may also be shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the brake force is too strong and too frequent, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to shake.

Generally, the symptoms can be solved after replacing the brake discs and brake pads. If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

The idle jitter of the steering machine is generally transmitted by the engine shake First determine whether the engine works smoothly and then check Don't have a headache and a pain in the feet, the general high-voltage line or high-voltage bag leakage aging The spark plug gap is too large, which is easy to cause the engine to work jitter.

I don't know if your car has been modified or crashed!

Check the distance from the center cover of the front wheel to the edge of the rear hub Measure the distance This is the most fundamental way, because your car may be bumped at high speeds, resulting in different distances between the two wheels, and that's how I did, just mistracking, but I can't check out what 4s I can, these stupid stupid people can! Later, I measured the distance at a friend's! Because there must be a difference in distance!

There must be a side short!

Also, if there is no problem in these places, it is simply a problem with the wheel tire, and each wheel with tire is dynamically balanced, marked separately, and then noted down the results of each data for comparison, if there is a big difference, it means that the wheel is deformed! This is what I learned from experience!

The problem of steering wheel shaking when the car is idling, as long as it is within the range of "reasonable shaking", there is no need to repair. The steering wheel of every car is shaking, but some cars are shaking imperceptibly, and some cars are shaking unbearably.

In the stage from "imperceptible" to "unbearable", there are many problems, among which there are also problems of each person's standard in the light of "unbearable".

Faulty jitter is generally noticeable. A slightly experienced repairman can easily figure out the cause at a glance, so this jitter repair is relatively easy.

There are many places where the engine is related to the whole car, and there are vibration isolation measures. For example, if the vibration isolation measures of the transmission link fail, the transmission lever will feel numb to the touch.

Steering wheel shaking is characteristic of the vibration of the whole car, and some vibrators that are not enough to cause the vibration of the whole car can only make a sound. Some people ask why the steering wheel doesn't shake when the speed increases? There are two reasons for this.

1. As soon as the speed is high, the vibration frequency will be high. When the vibration energy remains unchanged, the frequency is inversely proportional to the amplitude, and if the amplitude is small, the shaking of the steering wheel is not easy to detect.

2. The higher the speed, the greater the inertia of the flywheel, which attenuates the amplitude of the vibration source, and the steering wheel is not easy to shake.

In your case, there should be a problem with the steering wheel assist system, and it is recommended that you go to a local professional repair shop to check the specific situation.

This may be the case at high speeds, but you can still check it out at a 4S shop.

It may be that the carbon deposit, the fuel additives are useless, it is estimated that there is no need to clean the oil circuit now, I am almost 40,000 and all right, clean the throttle, mine is done at 20,000km, 100 meters.

Vehicle idle shake is generally caused by carbon deposits in the vehicle, and it is recommended to clean the throttle and fuel injector.

Steering wheel shake when idling: In fact, it is a failure caused by unstable idle caused by dirty throttle, and it will turn off when it is serious, and there will be no shaking when the idle speed is high, and it will not tremble when driving, if a cylinder does not work, then the engine will shake very badly, and the oil will also vibrate, especially when refueling urgently, the engine will shake, so go to clean the throttle to eliminate the fault. In this way, the engine mount is generally checked first, and if there is no problem with the bracket pad, the carbon deposit can be solved by cleaning.

Adjust the idle speed to the lowest as much as possible, which not only saves fuel but also reduces the volume and shaking of the car head.
