Which one of the following is NOT found on a parallelogram steering system?

In a parallelogram steering system, the primary components are designed to work together to allow for effective steering of the vehicle. The system typically includes a center link, tie rods, and a pitman arm.

The pinion gear, however, is associated with a rack and pinion steering system, which operates quite differently. In a parallelogram steering setup, the steering mechanism relies more on the combination of the center link and tie rods to transmit the driver's input from the steering wheel to the steering arms that move the wheels.

Understanding the components of each type of steering system can help reinforce why the pinion gear does not belong in the context of a parallelogram steering system, solidifying knowledge about steering mechanics in motor vehicles.
