When looking at that picture, look at the rectangular shaped metal piece under the bolt head, on your truck it is oval shaped, that's a cam eccentric bolt. When the bolt is turned, that oval turns and pushes the control arm, and that bolt moves in that slot that you will be punching out (if it hasn't been punched before).
Those controls Camber, the inward and outward tilt of the wheel.
