We say that the dynamic 4-wheel alignment is just a maintenance method. Under normal circumstances, if there is no problem with the vehicle, it is not necessary to do a 4-wheel alignment. In other words, the vehicle alignment only needs to be done when the vehicle really has a problem. Therefore, the 4-wheel alignment will not be done regularly like maintenance, but should be determined according to the situation. The conditions for doing a 4-wheel alignment are as follows:

1. When replacing chassis parts such as tie rods and adjusting the basic parameters of the four-wheel alignment of the car.

2,4 weeks when the tire is abnormally damaged.

3. The vehicle deviates to the left or right when the dynamic 4-wheel alignment instrument is driving in a straight line.

4. The steering wheel of the car is wobbling, shaking or too heavy when driving safely.

This also requires car owners to pay more attention to the safe driving experience when driving the vehicle, and check the use of tires more frequently.

The inaccuracy of the basic parameters of the dynamic 4-wheel alignment instrument is mostly caused by the obvious damage to the chassis parts during long-term driving, especially when the wheels hit the curbs, the vehicle has been involved in a collision accident, and the road conditions are very poor for long-term driving. If you can't feel the obvious problems, but always suspect that the wheel alignment is inaccurate, you can also do a car 4-wheel alignment inspection. For the question of how often to do it, if there are no obvious problems, then the "maintenance project" such as car 4-wheel alignment can be basically avoided.
