DESCRIPTION AND OPERATION

rod ends to the steering knuckles, which turn the
wheels.
If hydraulic assist is not available, manual control is
maintained. However, under these conditions, more
steering effort is required. The movement of the steering
wheel is transferred to the pinion. The movement of the
pinion is then transferred through the pinion teeth, which
meshs with the teeth on the rack, causing the rack to
move.
