The steering wheel of the car shakes, this situation is very common, 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.

In this case, it may be caused by uneven distribution of tire mass, and it is necessary to do a 4-wheel dynamic balancing to solve it.

Hello, first of all, it depends on whether the pattern is the same, is the tire a brand, it is best to choose the same pattern in front, and the dynamic balance should be able to solve your fault.
-
To do the dynamic balance, the balance is up to standard, and it will not shake
-
Most of this is to do tire dynamic balancing.

Steering wheel shake is an abnormal phenomenon when the car is running at high speed, which is related to many factors such as tires, suspension, resonance and brakes, specifically:
1. The tire causes shaking. Tires are an important device in direct contact between the car and the ground, and if there is a problem with the tire, it can be directly fed back to the driver, such as the tire is broken or deformed, and the driver can feel the problem most directly when driving. Generally, the repaired tires must be balanced once, if the dynamic balancing is not done, it may cause the steering wheel to shake, or replace the new tires, and the tire pressure of the four tires is not adjusted to the same, which will also cause the steering wheel to shake.
2. Suspension causes shaking. If there is no problem with the tires, the steering wheel shake may be related to the suspension. At this time, you should drive the car to the 4S store to check whether the chassis of the car is deformed or whether the lower arm and tie rod ball head are loose, which will also cause the steering wheel to shake.
3. Resonance causes jitter. Resonance causes steering wheel to shake, which generally occurs during the driving process, when the speed of the vehicle reaches a certain value, then the steering wheel begins to shake.
4. The steering wheel shakes due to the shaking of the brakes. When braking, the steering wheel or the whole car shakes a lot, which is likely to be a problem with the brake disc. Some drivers do not have good braking habits, and usually like to brake hard or suddenly, which can easily lead to the deformation of the brake disc, which also leads to steering wheel shake at high speeds.
Precautions for steering wheel shake.
When the car has a steering wheel shake, don't panic, determine whether it is driving shake or idle shake, if it is idle shake, you can go directly to the repair shop for maintenance, because the cause of shake is not easy to judge; If it is a driving shake, you must first judge the speed of the vehicle, judge whether it is a wheel problem or a steering transmission problem according to the speed, and then solve the problem in a targeted manner.
However, it should be noted that no matter what kind of problem causes the steering wheel to shake, it should be dealt with and solved in time, and do not go on the road with these problems, the danger factor is very high. You should take good care of your car and keep it in good condition.

The first possibility is that there is a problem with the tires of the vehicle, such as the inconsistent wear of the tires, the repaired tires, the dynamic balance problems, the deformation of the steel rim and the inconsistent tire pressure, then such problems may occur. If the steering wheel shakes at high speeds, the first thing you need to do is check the tires to see if there is a problem with them. Then check the dynamic balance of the vehicle, the tires of the car can be checked by themselves, but for the dynamic balance, professional instruments are required to detect.
If there is no problem with the tire and dynamic balance, then it may belong to the second situation, then it is very likely that the rubber sleeve of the front lower swing arm of the vehicle has aged and cracked, especially for relatively long vehicles, the probability of aging of the rubber sleeve is very large. The aging and cracking of the rubber sleeve causes the gap between the structures, which does not affect the vehicle at low speed, but increases the frequency when the vehicle is driving at high speed, so the impact will increase accordingly.

80-120 miles driving jitter, higher or lower than this interval fault disappears, then we should first check the four-wheel dynamic balance, which is also the most encountered by friends around us.
For example, the tire balance weight falls off, the tire is not dynamically balanced after repairing, or the dynamic balancing machine of some roadside shops is not accurate.
-
If the car runs at a high speed of more than 80 yards, the steering wheel shakes and generally needs to do the dynamic balance of the car tires. Because the tires may be deformed by stones or steel rims, or it may be that they are replaced with new tires.
-
When the steering wheel shakes at high speeds, I think it should be repaired in time, and the damn child should take a look.
-
Running high-speed steering wheel shaking? It turns out that these 4 reasons are too dangerous for many novices to know.
-
Brake pads or discs are worn unevenly.
-
Generally, the steering wheel shake is considered to be the inconsistent tire pressure of the four tires, or the dynamic balance and four-wheel alignment are not done in time after the tire is replaced.
-
Replacing new tires requires dynamic balancing, which may be that your dynamic balance is not done well.
-
It is estimated that the tire dynamic balance is not in place, and it is recommended to redo the tire dynamic balance.

If there is a slight shaking or deviation of the body during driving, it is generally caused by the fault. There are generally three reasons for this.
1. It may be that the tire balance is not good, and the owner needs to do a four-wheel alignment and dynamic balance as soon as possible.
2. It may be caused by the deformation of the steel rim, which requires the owner to go to the repair shop of the professional calendar for inspection, which generally occurs in the vehicle with a long service life. Generally, when the car is replaced with new tires and new steel rims, it is necessary to do a tire balance for the bucket car, otherwise the steering wheel will be prone to shake when the counterweight is uneven. Body shake will have an impact on driving comfort and handling judgment.
3. It is caused by the unbalanced deformation of the transmission empty shaft, which generally occurs in the ground collision of more cars.

The new tire brake steering wheel shakes the new tire brake steering wheel shake, to position, dynamic balance, bare brake disc, and now it is more shaken The new tire brake steering wheel shakes the new tire brake steering wheel shake, to position, dynamic balance, bare brake disc, and now it is more shaken The steering wheel shakes when stepping on the brakes, which is likely to be caused by the excessive amount of brake discs and brake pads. But don't be nervous when you encounter a slight shaking, just deal with it as soon as possible. The new tires need to be dynamically balanced, and the steering wheel will not shake after the dynamic balancing.
The wheels of a car are made up of tires and hubs. However, due to manufacturing reasons, it is impossible for the mass distribution of the parts of this whole to be very uniform. When the wheels of the car rotate at high speed, a dynamic imbalance will be formed, resulting in the phenomenon that the wheels of the vehicle shake and the steering wheel vibrates while driving.
In order to avoid this phenomenon or to eliminate the phenomenon that has already occurred, it is necessary to make the wheel correct the balance of each edge part by increasing the counterweight in the dynamic situation. The process of this correction is called dynamic balancing. Tires should be checked regularly for dynamic balance.
There are two types of tire balancing: dynamic balancing and static balancing. Dynamic imbalance causes the wheels to sway, causing the tires to wear in waves. Static imbalance can cause bumps and runouts, often causing flat spots in the tires. Therefore, checking the balance regularly not only prolongs the life of the tires, but also improves the stability of the car while driving.
Therefore, the dynamic balance should be done for new tires, and if the old tires are found to be shaken by the steering wheel, they should also be checked immediately. Driving safety is no trivial matter, and you must not be negligent. Here's how to do the balancing:
1. Put the tire on the dynamic balancing machine, fix it with a buckle, if there is an old balance weight on the tire, remove the old balance weight first. 2. Measure the distance from the machine to the tire rim, and enter the corresponding value on the machine. 3. Measure the width of the steel ring with calipers, get the value, and enter the data on the machine.
4. Read the radius of the tire steel rim, generally there will be specifications on the tire, for example, the radius of this tire is R13, enter 13 on the machine. 5. After the above steps are completed, you can press the start button on the machine, the tire will rotate at this time, and when the tire stops, the tire deviation value will be displayed on the machine. 6. Turn the tire by hand, when the inside of the machine shows a full grid, you can add the corresponding balance weight on the inside, if the value is too large, you can add several balance blocks to get the displayed value.
7. After the inner side is added, continue to rotate the tire by hand, and when the outer side is full, add the balance weight on the outside. 8. Press the start button on the machine again, the tire rotates, and after stopping, two 00 values are displayed on the machine, indicating that the dynamic balance is done. 2019

1. Direction machine problem:
1) Excessive wear of the ball joint of the tie rod of the steering machine: because it is active, it will wear out after a long time, and there will be subtle angle inaccuracy when steering after the problem, so there will be tire shaking and blurred steering at high speed;
2) Wear of fixed rubber bushing of steering machine: This problem is relatively rare, and it is easy to overhaul, and it only needs to be seen with the naked eye, but once it is worn, it will cause the steering wheel to tremble when driving.
2. There is a problem with the tire:
1) Wheel rim deformation: Generally, the wheel rim will be deformed due to violent impact by external force, and it is more likely to cause problems on some cars with flat tire size, and the wheel hub needs to be replaced;
2) Tire imbalance: Some car owners do not carry out tire dynamic balancing after disassembling and assembling tires, which will cause the high-speed steering wheel to tremble, and generally go to the tire shop to carry out tire dynamic balancing to solve the problem;
3) Tire deformation: Carefully stroke the four tire tread parts of the car with your hands, if you find that the tire tread is jagged, or a tire has a rather abrupt "bulge", it is tire deformation. Sometimes the tire is pierced by nails, which can also cause abnormal noise and heel shake.
3. Deformation of the transmission shaft
1) When the car collides, scratches hard things and damages such as curbs, stones, etc.;
2) The screws of the transmission shaft are seriously loosened or lost, resulting in misalignment;
3) The installation angle of the flange fork and telescopic fork is wrong, and the waist beam bearing and shock absorbing rubber ring of the multi-section drive shaft are damaged;
4) When the transmission pump is twisted and deformed, the feeling of shaking is especially obvious when the car accelerates.

Generally, after the car is replaced with new tires, the new tires need to be dynamically balanced, and the steering wheel will not shake after the dynamic balance is done. It is recommended that you do the balancing as soon as possible.
Precautions for replacing new tires:
1. Choose the appropriate tire specifications (should be consistent with the specifications on the original car, if you need to change the tire specifications, you must go to a professional tuning shop for tire upgrades or consult the vehicle manufacturer).
2. Ensure that the tires must be the same as another tire with the same axle, that is, the same axle should be equipped with tires of the same specification (including speed level and load index), brand, pattern (including special markings).
3. The new tire must be dynamically balanced. Theoretically, you have to balance the tire when you remove it from the rim and put it back on, because you can't restore the position of the removed tire and the rim.
4. It is not recommended to replace only one tire. The principle of replacing tires is: coaxial tires must be of the same brand, the same pattern, the same size, the same load index, the same speed level, and the same tread depth, which is for safe driving considerations.
5. When replacing new tires, you must replace the valve with a new one. This is because the valve is a rubber product, and there is a problem with the aging cycle of the spine. When a new tire is replaced, although the valve does not see the problem at the time, the valve may deteriorate prematurely during the life cycle of the new tire, causing a safety hazard.
6. If only two tires are replaced, the new tires must be installed on the rear axle of the vehicle. Note: If you put a tire with more wear on the rear axle of the vehicle, because the weak drainage capacity of the tire will greatly increase the risk of oversteering of the vehicle in rainy days, and the risk of vehicle flicking may occur.
It depends on individual needs. If it's quiet, you can choose Michelin, but this tire is a bit soft and wears out faster than other brands. Regular tires are Dunlop, Goodyear, Bridgestone, and Hankook. >>>More

If the wheel hub is bent, broken or severely corroded, the hub should be replaced in time. If the damaged wheel is not replaced, there is a high risk that the tire will slip out of the wheel and even cause problems such as loss of control. However, if it is just accidentally scratched, it is not a big problem, and the wheel hub will have to be replaced if it is deformed or dropped directly. >>>More
