In a parallelogram steering linkage, which component does the pitman arm support?

• A. Tie rod end
• B. Center link
• C. Steering knuckle
• D. Rack and pinion

Answer: (B)

In a parallelogram steering linkage, the Pitman arm acts as a lever connected to the steering box output and converts the rotation of the steering wheel into a back-and-forth linear motion. This motion is applied to the center link, which runs between the two sides of the linkage and connects to the ends of the tie rods. So the Pitman arm directly supports and drives the center link, transmitting the steering action to the rest of the linkage. The tie rod ends and steering knuckles are connected to the center link to move the wheels, while rack and pinion is a different steering setup that isn’t the component the Pitman arm supports in this arrangement.
