Important: DO NOT disassemble the power steering gear.

The power rack and pinion steering system has a control valve which directs hydraulic fluid under pressure to either side of the rack piston. The piston, attached to the rack, uses hydraulic pressure to move the steering rack left or right. This moves the tie rods and steering knuckles, which turn the front wheels.

If the hydraulic assist should fail, manual control is maintained, however, under this condition more steering effort is required.
