The manual steering system consists of a tube which contains the toothed rack, a pinion, the rack slipper, and the rack slipper spring. Steering effort is transmitted to the steering arms by the tie rods which are coupled to the ends of the rack, and the tie rod ends. The connection between the ends of the rack and the tie rod is protected by a bellows type oil seal which retains the gear lubricant.
The power steering system consists of four major parts: the power gear, power steering pump, pressure hose and the return hose. As with the manual system, the turning of the steering wheel is converted into linear travel through the meshing of the helical pinion teeth with the rack teeth. Power assist is provided by an open center, rotary type, three-way control valve which directs fluid to either side of the rack control piston.
