The factory Saginaw power steering box on classic C10 trucks is a durable unit, but after 50+ years they develop play and require rebuilding or replacement. This thread compares your options: rebuild the original, install a rebuilt unit, or upgrade to a modern ratio box.
We cover what wear to look for, quick-ratio vs stock ratio gearboxes, and the difference between rebuilding for reliability vs upgrading for performance. Also discusses sector shaft seal replacement and preload adjustment.
For trucks making the full switch from manual to power steering, the GELUOXI Power Steering Gear Box Kit for 1967-1972 C10 is a great complete solution.
