Problems with car steering wheel jitter? What is the problem of car steering wheel shaking

There are many reasons for the vibration of the steering wheel of the car, and the reasons for the road surface are roughly as follows: 1. The free travel of the steering wheel becomes smaller, and the slight vibration caused by the road surface state is directly fed back to the steering wheel, and the free travel of the steering wheel can be adjusted in this case; 2. The toe-in of the car is inaccurate, resulting in the deviation of the car or the vibration of the steering wheel at a certain speed value, which usually appears in the car that has been used for a long time or the front wheel has been strongly impacted, and the four-wheel alignment correction can be made; 3. The steering wheel vibration caused by tire deformation, the tread pattern of poor quality or scrapped tires is dislocated due to shoulder deformation, forming periodic vibration, and the tire can be replaced; 4. The deformation or failure of the components of the automobile suspension system and steering system, such as the loose connection parts of the directional power assist system, the wear of the rubber sleeve of the movable connecting rod, etc., need to be checked in detail to determine the fault before it can be eliminated.

The reasons for the idle steering wheel shake are: 1. The most common thing is that the throttle is dirty or the throttle is faulty, which will lead to idle jitter; 2. The spark plug does not ignite, resulting in one or more cylinders not working, which will also lead to idle shaking. 3. The oil pressure is unstable, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is poor, it will cause the body to shake.

4. The quality of gasoline is not good, resulting in poor atomization effect of the fuel injector, and insufficient combustion of the mixture in the cylinder will also lead to idle jitter. With the car used for a long time, or often take some roads in poor road conditions, when the vehicle idles, the engine shakes very much, the steering wheel is even a little shocking, and the steering wheel vibrates even more when the car air conditioner is turned on.

Do a four-wheel alignment. Low-speed shaking is mostly due to the wheel pier, or the tire is wrapped, touch the tread and side of the tire to see if there is any obvious bagging. If you do, you'll have to change your tires.

Check whether the tire pressure is consistent, if it is inconsistent, if it is not consistent, if it is not good, you have to do positioning. Adjust the toe-in and you're good to go. It is recommended to find a better one.

The most likely is misalignment of the wheels. I used to have steering wheel shakes, especially above 90 miles, and then I eliminated the four-wheel alignment failure. It is recommended that the landlord do a four-wheel alignment, which is not expensive.

When the wheels of the car rotate at high speed, the balance state of the body is broken, resulting in the phenomenon of shaking the body and steering wheel of the vehicle while driving, which can be solved by doing the dynamic balance.

Causes and solutions for car steering wheel shake.

The steering wheel is shaking, the seat is numb, let me tell you the solution.

Why does a car steering wheel shake?

What is the problem of car steering wheel shaking

The steering wheel of a car is a relatively flexible component, and you have to turn it every day when you drive. Under normal circumstances, the steering wheel will not have obvious shaking, and there will be many reasons for the steering wheel shaking under abnormal circumstances, but most of them are caused by resonance, and there are really too few problems with the steering wheel accessories. The steering wheel shake that occurs in each state of the car basically corresponds to a specific problem, so let's take a look at the three reasons for the steering wheel shake today.

The first is that the steering wheel shakes when idling.

Generally, when idling, the engine will vibrate, and the vibration will be transmitted to the steering wheel along the frame. However, under normal circumstances, the vibration transmitted to the steering wheel is minimal, and I remember that when I buy a car, the sales deliberately let me hold the steering wheel to feel how small the vibration is.

If you feel the steering wheel vibration when idling, it is most likely that a part of the steering wheel is loose and causes resonance. Usually this is not a big problem, but novice friends can't do it on their own, and going to a repair shop can solve it quickly.

Second, the steering wheel shakes when the vehicle is moving.

I am deeply aware of this situation, the most important phenomenon is that the steering wheel will shake more and more violently with the acceleration of the speed of the vehicle when the vehicle is driving. When I encountered this situation before, my hands were numb with shaking, and this situation was basically a tire problem.

Because only the tire will speed up with the size of the throttle, generally if the tire repair or tire change is not done in time to do the dynamic balance, there will be jitter, if the balance of the tire is worse, the greater the shake. In this case, you need to reduce the speed as much as possible, go to the tire shop in time to do the dynamic balance of the tire, and if necessary, blindly do the four-wheel alignment.

The third is steering wheel shake when braking. with rocks.

I don't know if you have ever encountered the situation that the ABS anti-lock SI system of the vehicle intervenes when braking suddenly, generally if the brake is too urgent, the tire may be hugged SI when ABS will intervene, and the method of high-frequency point braking is taken to prevent the tire from holding SI, at this time, there will be steering wheel shake and brake pedal shake.

If the steering wheel shakes when the ABS is activated during the emergency braking, it is most likely caused by uneven brake pads and brake discs, and it is necessary to go to the repair shop as soon as possible to check and replace the brake pads and other accessories.

The steering wheel shake in the car is mainly caused by the following reasons: 1. The steering gear bearing is too loose or the steering gear gear transmission pair clearance is too large.

2. The ball joint pins of the main and tie rods are worn loosely and loose.

3. The kingpin and lining pin of the steering knuckle are seriously worn, and the matching gap is too large.

4. The front hub bearing is loose.

5. The front wheel is bent and the rivet is loose.

6. The frame and rim are deformed.

7. The toe-in is too large.

When to shake, how long and how far the front tires have run.

It's not uncommon for the steering wheel to shake while driving

Some car owners can feel a strong steering wheel shake when driving a car at high speeds of more than 80-100km h. 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 steering wheel is shaking, the seat is numb, let me tell you the solution.

When the car is idling, you can deal with it if you find that there is a noticeable shake in the steering wheel.

1.Replace the car spark plug. The engine spark plug is due to the embrittlement of the insulating layer applied in the interior for a long time, resulting in the secondary flashover or the flashover performance is not very good, resulting in the unstable operation of the engine, so the steering wheel of the car will shake.

2.Replace engine fuel. The engine burns less oil, and it will also cause the idle steering wheel to shake.

The gasoline of not very good quality will not burn enough, and in the case of the engine gasoline entering the cylinder, it is very easy to be absorbed by carbon deposits, which will cause the car engine to not reach the best state, of course, it will cause the situation of shaking.

3.Clean the throttle. If the electronic throttle valve has a serious carbon deposit, the electronic throttle opening will be inaccurate enough, causing the engine to shake when the car is hot.

If the engine is still shaking after the electronic throttle is cleared, it may be a problem with the total range of the electronic throttle, and it is necessary to go to the car 4S shop to carry out the replacement at this moment.

When the car is driving, the steering wheel shakes according to different driving conditions. At a speed of 30-40km h, the steering wheel shakes and the body shakes, if these problems occur are generally caused by wrong operation or car tire deformation caused by a long period of car tires, at this time you can only replace them with new wheels.

When the car is traveling at a speed of about 80 kilometers to 90 kilometers, the steering wheel shakes and recovers when the speed exceeds 90 kilometers. Most of this situation occurs because of the deformation of car tires or the reduction of the influence of the transmission device, it is necessary to check whether the precise positioning angle of the front tire and the toe are in accordance with the regulations, such as the return error must be adjusted, and at the same time check the dynamic balance of the car wheel rotor and whether the deformation of the car tire is too large, if there is a problem, it must be replaced.

If it is a car that has already run more than 50,000 kilometers, then you need to check whether your car brake pads have become thinner and thinner, if it is indeed a car brake pads that have become softer, you must replace a new pair of car brake pads. If you replace the car brake pads have not solved this problem, you must check the brake pads, the brake pads have been for a long time, and the deformation causes the brake pedal to shake and shake the hands of the car steering wheel, we can replace the brake pads immediately, and the shaking problem will be solved immediately. However, the brake pads are not cost-effective, so you can take them to a place where there are CNC lathe machines and equipment to test it.

In addition, if you press the brake pedal at high speed, the steering wheel shakes or it may be that the car transmission device is abnormal, so it is best to check whether the steering cross support rod and steering tie rod cage are rusty or loose.

Steering wheel shake, is not mainly the problem of the steering system, but the wheel, chassis problem, this kind of fault is also easier to solve, in the usual vehicle failure is also more common, the following is to list some of the main reasons: 1, tire dynamic balance inaccuracy. The inaccurate value of the tire dynamic balance will cause the car to shake the steering wheel within a certain speed range, beyond this.

It may be due to a malfunction of the spark plug and an aging condition. It could also be because the engine performance is unstable, or it may be because the speed and gear do not match, or because the tires of the car are deformed, or it may be affected by the transmission, or the brake pads of the car are faulty.

The steering wheel of the car shakes, it may be a problem with the poor balance of the tires, the problem of the wheel, too much friction, and high-speed driving, which will affect the shake.

It may be caused by spark plugs, or the engine is not working, or it may be caused by drag gear, or it may be caused by road conditions, or the engine is loose.

Car steering wheel shake mostly occurs in a certain speed range, and some are when braking violently. So what is the cause of a car steering wheel shake? In this article, the Chinese Internet of Things will tell you a few things!

Reasons for the shaking of the steering wheel of the car1The dynamic balance of the tire is not accurate. Inaccurate tire dynamic balance values will cause the steering wheel to shake and lead within a certain speed range, beyond which the fault will disappear.

You need to send friends to redo the wheel dynamic balance. 2.The brake disc is uneven.

This fault is mainly manifested in the shaking of the steering wheel during high-speed braking, and the brake disc needs to be replaced. 3.Half-shaft failure.

The half-shaft fault is mainly manifested in the fact that the steering wheel will shake when the vehicle accelerates, and the half-shaft needs to be checked. The above is an introduction to the causes of steering wheel shake in cars, especially the first two. If the fault is not eliminated, it is necessary to check the vehicle suspension, tie rod ball joint, balance bar rubber sleeve and other components.

Hope it helps.

Analysis of the original circle of automobile jitter:

1. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. So, when the electrical system, especially the air conditioner, is turned on, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

2. Tire problems.

For tires, the car must be balanced once when replacing new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

3. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the throttle valve will be too dirty to cause the throttle to close loosely or the idle motor to stagnate, resulting in too high idle speed, and the carbon deposit generated by the engine in the process will also cause the vehicle to shake, especially when starting the vehicle, the engine will shake more than normal, and even sometimes there will be a phenomenon that can not be started at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or throttle cleaner in time.

4. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.
