Is there a slight shake in the steering wheel when idling

Hello! As for the question you mentioned, the first thing to look at is the frequency and vibration of the steering wheel shake when idling, and if it is only a slight shake, then it is not a big problem. Many cars will have a certain vibration when idling, and the resonance frequency of the whole vehicle is close to the resonance frequency of the engine at idle, which is difficult to improve.

If you don't feel noticeable vibrations anymore, there's no problem. If there is a significant vibration when the vehicle is driving, it needs to be checked. The above suggestions are for your reference only.

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.

Generally, the car has no direction, and there is a situation of shaking, and I think this is normal if you don't have it.

There are many reasons for a car steering wheel to shake: toe-in failure, loss of wheel dynamic balance lead, loose push rod, loose wheel bearings, damage to steering shock absorbers, etc.

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.

There's a slight shaking, then you're going to have to check the engine foot squat.

It is advisable to clean the air intake system. The throttle is dirty, the weather is cold, and the intake pressure is small.

Steering wheel shake is a common situation encountered by many car owners. If the owner finds that the body shakes significantly when starting the vehicle or stopping the vehicle without turning off the engine, it may mean that the vehicle has the following three conditions: 1

The most common cause of car shake caused by serious carbon deposits in the engine is that the throttle valve is too dirty or the fuel injector is too much carbon. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, resulting in the mixture of cold start is too thin, making it difficult to start, in this case, only when the gasoline absorbed by the carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned. 2.

Ignition system problems Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug flashing condition is not good will also lead to this kind of failure. Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3.If the oil pressure is unstable, if you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is not good, the body shakes will be caused. Workaround:

Check the oil pressure and replace parts if necessary. 4. Aging of engine parts Automobile shake is also related to the aging of engine feet (also known as claw pads). The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

In this case, the throttle can be cleaned, and it is likely that the engine is caused by carbon deposits.

It may be that the engine gasket is aging.

1. The steering wheel shakes when idling is largely caused by the engine running unsmoothly and stably, and the idle shake caused by resonance is not very likely, because the starting speed is low when idling, and the resonance caused by low speed is unlikely, so the steering wheel shakes when idling, and it is recommended to go to the 4S shop for inspection and maintenance.

Second, when the engine is idling, due to the small amount of air intake, and the air cleaner is too dense to cause difficulty in suction, resulting in unstable engine speed, which causes the steering wheel to shake, such as removing the shake of the cleaner and disappearing, and replacing the air cleaner with a density that is not so large jitter can also be improved, but the excessive effect on dust will be reduced. Therefore, if you want to solve the jitter, you need to modify the engine intake system to completely solve it.
