Steering box with pitman arm systems use a parallelogram-type steering linkage.

Yes, that's correct. The steering box with pitman arm system, also known as the recirculating ball steering system, uses a parallelogram-type steering linkage. This system consists of several components including the steering box, pitman arm, idler arm, and tie rods.

Here's a step-by-step explanation of how it works:

1. When the driver turns the steering wheel, it rotates the steering shaft, which is connected to the steering box.

2. Inside the steering box, there's a worm gear attached to the end of the steering shaft. This worm gear spins a sector gear, which moves up and down as the worm gear turns.

3. The sector gear is connected to the pitman arm, which converts the rotational motion of the gears into linear motion.

4. The pitman arm is connected to the steering linkage (the parallelogram assembly), which includes the idler arm and tie rods. The movement of the pitman arm pushes or pulls the steering linkage.

5. The steering linkage, in turn, pushes or pulls the steering arms of the wheels, causing the wheels to turn left or right.

This system is commonly used in larger vehicles like trucks and SUVs because it's robust and can handle a lot of weight.
