The typical layout is a column and shaft leading from the steering wheel to a frame-mounted gear mechanism. This steering shaft rotates left and right, turning a cross-shaft within the gear. The cross-shaft rotates the pitman arm, and depending upon the front axle layout, the pitman arm moves either fore-and-aft or laterally. Mid-'60s Ford manual steering uses Saginaw's recirculating ball-and-nut engineering. Ford trucks relied on Gemmer worm-and-roller steering from 1937-60. The transition to ball-and-nut steering was an improvement in efficiency and dramatically increased the longevity of manual steering gears.
