UNIT REPAIR

The unit repair of this section is similar to the unit repair of power Steering gear. Refer to Section 6C, Power Steering Gear.

GENERAL DESCRIPTION AND SYSTEM OPERATION

Manual Rack and Pinion

The manual rack and pinion steering system consists of two main components: the rack and the pinion. The motion of the pinion is transferred through the pinion teeth that mesh with the teeth on the rack, which moves the rack. The force is then transmitted through the arms on the struts, which turn the wheels.
