The reasons for the unsteady driving, head swinging, and even steering wheel shaking of the car at high speed or at a certain high speed are as follows:
1. The positioning angle of the front wheel is inaccurate, and the toe is too large.
2. The air pressure of the front tire is too low or the tire is unbalanced due to repair and other reasons.
3. The front spokes are deformed or the number of tire bolts is different.
4. The installation of transmission system parts is loose.
5. The transmission shaft is bent, the power is unbalanced, and the front axle is deformed.
6. Shock absorber failure.
There are two situations of high-speed oscillation, one is that the oscillation becomes stronger with the increase of vehicle speed, and the other is oscillation occurs at a higher speed, which causes the steering wheel to shake. The drive axle can be erected first, the front wheel is plugged with safety plug blocks, the engine is started and gradually shifted into the high-speed gear, so that the drive wheel reaches the final test oscillation speed. If both the body and steering wheel shake at this time, it is caused by the drivetrain.
Because the front axle of the front wheel is in a stationary state at this time, if the final test oscillation speed is reached, the car does not shake, then the reason for the oscillation is that the front axle part of the car is faulty; Check whether the positioning angle and toe of the front wheel meet the requirements, and adjust if it is out of alignment; Set up the front axle and test the wheels to check the dynamic balance of the wheels and whether the tires are too deformed. If necessary, a good wheel can be replaced for a comparative test; Check whether the front axle and frame are deformed, check whether the transmission shaft is bent, and make the dynamic balance of the transmission shaft when possible.

What happens to the deformation of the front axle of a car? The deformation of the front axle of the car will cause the engine to tremble, which will drive the entire body to tremble, and will also lead to abnormal noise and oil leakage during driving.
-
Mistracking of the vehicle will occur.

The symptoms that will occur in the front plexus of the deformation of the half shaft of the car are as follows:
1. The deformation of the half shaft of the car will cause violent shaking when running;
2. The deformation of the half shaft of the car is light and abnormal when running, and the spine is bumpy, and it cannot be driven if it is heavy, and the car will deviate;
3. The half-shaft of the car is deformed, which will cause the tire to wear out for a long time.
-
If the front drive shaft of the car is broken, the car cannot move. If you hear a rattling sound while driving, it means that there is a problem with the propeller shaft. The propeller shaft transmits power, so it needs to be replaced if there are symptoms.
The propeller shaft is the shaft that can transmit power in the propeller shaft of the universal transmission. It is a rotating body with high key velocity and less support, so its dynamic balance is crucial.

The half shaft of the car is deformed, and there will be a violent shaking phenomenon when running.
1. The deformation of the half shaft of the car will cause abnormal noise and bumps when running, and it will not be able to drive if it is heavy, and the car will deviate and shake violently.
2. The half shaft of the car is deformed, which will cause the tire to wear out for a long time.
3. The half-shaft, also called the drive shaft, is the shaft that connects the differential with the drive wheel. The half-shaft is the shaft that transmits torque between the gearbox reducer and the driving wheel, and its inner and outer ends have a universal joint respectively connected with the inner ring of the reducer gear and the hub bearing through the spline on the universal joint.
4. The half-shaft is used to transmit power between the differential and the driving wheel. The half-shaft of the ordinary non-disconnecting drive axle can be divided into three types: full floating, 3 4 floating and semi-floating according to the different forms of external support. If deformed, it is recommended to replace it immediately.

Symptoms of malfunction:
Rotation of the gear-wheel on the shaft. Sometimes there is a momentary pause. This could be a damaged connection key on the shaft.
Rotational deflection of the pulley on the shaft. This may be due to the large gap between the pulley bore and the shaft, the shaft diameter being too small, or the pulley bore diameter being too large.
The rotating gears of the shaft have periodic meshing rotation noise, which may be caused by the bending of the transmission shaft.
The diameter of the shaft and the rolling bearing part becomes smaller, and the shaft rotates in the inner sleeve of the rolling bearing, so that the temperature rise of the bearing position is higher.
Cause of the failure. The temperature of the barrel is low or metal foreign matter falls into the barrel. Bending deformation occurs due to a sudden increase in the torque of the transmission shaft
The bearings at both ends of the transmission shaft are often damaged, and the diameter of the matching part of the shaft and the rolling bearing is reduced due to the wear of the shaft by disassembling the rolling shaft many times, and the interference fit between the inner sleeve of the rolling bearing and the diameter of the transmission shaft cannot be guaranteed.
The gear bore and the shaft fit clearance is large. Sometimes the gearing work is overloaded. Cause damage to the connecting key, so that the size of the keyway on the shaft changes.

Broken front driveshaft of the car:
The abnormal sound of rattling, no matter how serious it is, is that the car is lying on its stomach and does not go away when it steps on the accelerator (the car makes continuous noises during the whole driving process);
There is a crash sound on the transmission shaft when the car starts or shifts gears during driving, especially when driving at low speed in high-speed gears.
There is no abnormal sound of the transmission shaft when the car starts, and there is an impact sound of the transmission shaft when the car is driving or there is an abnormal sound of the transmission shaft when the car is coasting.

Hello, oil leakage is one of them, if the front half axle of the front area of the car is broken, the right front wheel is broken, there is no power, the left front wheel is broken, and the rear is broken. There is an abnormal noise. I hope it can help you with your car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The installation of equipment power is not enough can be extended with a three-to-three interface, opening the window ventilation is the best and most environmentally friendly way to deodorize the new car, open all the windows before driving, you can also put some grapefruit peel bamboo charcoal bag to assist in deodorization, open the sunroof during driving.
The noise of the Taiwan Bi-Sonic fan was measured in a non-reverberating chamber with a background noise of less than 15 dB. The fan to be tested runs in free air, and a noise meter is disposed of one meter away from the air inlet. >>>More
Clause. 1. Brightness.
Brightness is an aspect of the good or bad car wax, but the brightness has foggy greasy brightness and natural brightness, generally good car wax is natural brightness and clarity obvious, but no matter how good the car wax, for dark car paint plain car paint (such as: Japanese, domestic, general series dark car paint) The brightness improvement is very obvious, for metal paint, light-colored paint, especially the improvement of the brightness of the new car, it is not easy to distinguish with the naked eye, that is, it is not obvious, this is because of the characteristics of the paint itself and the principle of light! >>>More
Tire balance weights not only help to prolong the service life of tires and the normal performance of vehicles, but also contribute to the safety of drivers. Unbalanced tire movement can lead to irregular tire wear and unnecessary wear on the vehicle's suspension system, and unbalanced tire driving on the road can also cause vehicle bumps, resulting in driving fatigue.
Gasoline engines cannot add diesel, gasoline and diesel have different ignition points, and the combustion environment they adapt to is different. If the gasoline and diesel are mixed, after the gasoline is burned, it will die and the car will not be able to start, and the engine fault indicator will be on! Hope the above is helpful to you, thanks.
