Generally speaking, according to the actual problems of the car, the right medicine is enough. Just like if we have a headache, there is no need to take a medicine for headache and a medicine for stomachache, right?

There is no need for dynamic balance and four-wheel alignment to do Ma Jianjun's paper published in Technology and Market, and the different functions and analysis of automobile four-wheel alignment and wheel dynamic balance.

As mentioned above, the inspection and adjustment of tire dynamic balance is to ensure the driving stability of each tire, and the inspection and adjustment of four-wheel alignment is to ensure the driving track of the wheel.

Under what circumstances do you need to do tire dynamic balance? Generally speaking, as long as you have changed or repaired tires and wheels, you need to do dynamic balance, because the circle of tires is not an absolute circle. Under what circumstances do you need to do four-wheel alignment? Under what circumstances do you need to do four-wheel alignment?
