What is the simplest method to adjust toe-in?

[VanErin]

First, inflate all tires to the appropriate pressure for the car, ensuring all four tires are roughly consistent to achieve a stable placement of the vehicle. Use a long ruler to measure the distance between the centers of the car's wheels, then measure the distance between the front edges of the front wheels at the rear. The difference between these two measurements is the toe-in value. Turn the steering wheel fully in one direction, then use a wrench and tools to adjust the axle to the appropriate position and tighten it. Measure the rear wheels using the same method, adjust them accordingly, and finally remeasure the toe-in value to ensure it falls within the specified range.
