I believe many car owners often hear about four-wheel alignment，Many friends have changed the tires after changing them，I am often tricked into doing wheel alignment by unscrupulous roadside shops，It turned out to be a waste of money，It also damages the original coefficients of various parts of the car，It will also be difficult to drive。

Then，What is four-wheel alignment?When should you do a four-wheel alignment?What is the difference between four-wheel alignment and dynamic balancing?

In simple terms，Four-wheel alignment is to adjust the position of various components of the chassis，Restore it to factory settings。

Due to the four wheels of the vehicle、Steering mechanism、The installation between the front and rear axles should have a certain relative position，This relative position is the standard value set by the manufacturer，If deviation occurs，The car will have various malfunctions。

Adjust the installation to restore this location，It’s four wheel alignment，It can ensure the straight driving of the vehicle、Driving stability and automatic steering return function, etc.，And reduce tire wear and extend service life。

If you ask how often a wheel alignment needs seabet appto be done，In fact, there is no fixed cycle。

Four-wheel alignment and maintenance are different，It is a means of maintenance。When there are no problems，There is no need for four-wheel alignment，A four-wheel alignment is only required when there is a problem with the vehicle。

Relatively speaking，Those who often get on the curb (especially from the front wheel) or often pass speed bumps quickly，And vehicles that are accidentally hit in traffic accidents and other accidents are more likely to cause deviations in wheel alignment，And then exhibit the following problems，You need to pay attention:

We all know that the steering wheel has an automatic return function，In fact, this is due to accurate four-wheel alignment。If one day you find that the car will veer to the left or right involuntarily，You have to keep adjusting the steering wheel to keep driving in a straight line，At this time, you need to do a four-wheel alignment。

We don’t check the tires carefully when driving，But we recommend carefully checking the tire condition every 20,000 kilometers or 1 year，Check if there is any eccentric wear，If you find what we often call fetal eating，You need to do a four-wheel alignment。

After the car was hit，If the suspension is damaged，It is also necessary to re-adjust the four-wheel parameters。Also，The steering wheel floats while driving、Shaking or being overweight may also be caused by inaccurate four-wheel alignment parameters。

I emphasize again: If the above situation does not occur，There is no need to do wheel alignment frequently，If the coefficients of each component are adjusted unnecessarily，It is possible to change the original coefficients of various components of the vehicle，On the contrary, it causes inaccurate four-wheel positioning of the vehicle。

Different from four-wheel alignment，Dynamic balancing only adjusts the unevenness of the wheel itself。

Due to manufacturing reasons，The mass distribution of each part of the wheel (tire and hub) cannot be very uniform。When the wheels rotate at high speed，A dynamic unbalanced state will be formed，Causes the wheels of the vehicle to vibrate while driving、Steering wheel vibration phenomenon。In order to avoid or eliminate this phenomenon，It is necessary to make the wheel dynamically increase the counterweight，Correct the balance of each edge of the wheel，This correction process is dynamic balancing。

Dynamic balancing can ensure that the tires can drive smoothly，Prevent jitter，Make the car more stable and safer to drive on the highway。

Generally，As long as the tire system (tire or wheel) has been replaced or repaired，Dynamic balancing is required，And some individual vehicles，Because it has been used for too long，It will also cause the "dynamic balancing weight block" to fall off，It will cause the tire weight balance to be imbalanced，Dynamic balancing is also required at this time。

Dynamic balancing only adjusts the weight balance of the tire，Generally, as long as the tire is "moved"，Need to do everything。

Four-wheel alignment is to adjust the angle coefficient between the vehicle chassis system，It is a maintenance method，So don’t do it easily。Compared to dynamic balancing，The construction process of four-wheel alignment is much more complicated，The charges are also relatively high。

Finally，Whether it is dynamic balancing or four-wheel alignment，It is recommended to find a professional 4S shop to do it，Avoid the parameter adjustment becoming more chaotic due to unprofessional maintenance technicians，It may also damage the car。Also，You should also pay attention to your usual car habits，Bad driving habits are likely to make seabet appyou a "frequent user" of four-wheel alignment。
