The rotary motion of the steering wheel transfers through the following components:

• | The steering upper shaft

• | The lower shaft

• | The steering gear

The pitman arm attaches to the center link. As the pitman arm rotates, the center link moves linearly, actuating the right tie rod and the left tie rod. The right tie rod and the left tie rod turn the wheels right or left through the steering knuckles. The steering system is designed for the following purposes:

• | Easy steering

• | High durability

• | Excellent steering reaction

• | Reliable self-restoring action
