Two support members of the parallelogram steering linkage are the which two arms?

In a parallelogram steering linkage, the two arms that provide the support are the Pitman arm and the Idler arm. The Pitman arm is driven by the steering box and pushes/pulls the center link, while the Idler arm provides a opposite mounting point on the frame to keep the center link aligned. Together with the center link and the tie rods, they form the parallelogram shape and ensure the front wheels turn in unison as you steer. The other parts aren’t the supporting arms of that parallelogram: tie rods connect the center link to the steering knuckles and transfer motion, and rack-and-pinion components pertain to a different steering arrangement, not the parallelogram setup.
