1. Measure the toe-in value, because the toe-in value is determined by the length of the tie rod, and the size of each tie rod is required to be different;
2. The connection between the tie rod and the ball head of the tie rod is connected by threads, which cannot ensure the consistency of the connection length;
3. After each replacement of the tie rod, the toe-in value must be measured to ensure the normal toe-in value;
4. The left and right steering angles are different. If the four-wheel alignment is done, the steering wheel angle will have a small difference. Adjusting from the left and right pull rods of the steering wheel will not have a big impact on the steering angle.
