The parallelogram steering system gets it's name because: a. The center link and the idler arm run parallel to each other. b. The pitman arm and the axle always run parallel to each other. c. The wheels run parallel to each other. d. The pitman and idler arms run parallel to each other.

The correct answer is a. The center link and the idler arm run parallel to each other.<br /><br />In a parallelogram steering system, the center link (also known as the tie rod) and the idler arm are connected in such a way that they maintain a parallel relationship with each other. This parallel arrangement allows for smooth and stable steering motion, as the forces and torques generated during steering are evenly distributed between the two parallel components.
