After the car has been used for a long time, if the dynamic wheel alignment finds that the direction becomes thick, trembling, the vehicle is running off the track, tilting, not returning to the original position, or one side of the tire is damaged, wavy, small pieces are damaged, eccentric wear and other abnormal damage, and the customer feels the car floating, shaking, swinging and other phenomena occur when driving safely, it is necessary to consider checking the correct alignment value of the wheels to see if the deviation is too large and repair it immediately.

What is the definition of a car's dynamic 4-wheel alignment? Front tire alignment includes caster angle, kingpin inclination angle, front tire camber angle and front wheel toe. Rear tire alignment includes wheel camber angle and rear tire toe. Front tire alignment and rear tire alignment are collectively called wheel alignment, which is commonly known as 4-wheel alignment. The effect of wheel alignment is to make the vehicle run straight and become light, and reduce the damage of tires and components during driving.

In addition, everyone must be especially aware of certain misconceptions, such as:

Misconception 1. To do a 4-wheel alignment is to adjust the toe of the front wheels. The front wheels not only have toe angles, but also camber angles, caster angles, and kingpin inclination angles. The rear wheels also have toe angles, as well as camber angles and thrust angles, which are key positioning angles.

Misconception 2: I think all dynamic wheel alignment instruments are the same. Whether the wheel alignment of a car is qualified depends on the ability of the maintenance personnel and the quality of the detection instrument.
