As before, this information was compiled while working on my 1970 Chevelle SS, but is relative and applicable to 3rd, 4th and 5th Gen El Caminos.
While cleaning and painting the front clip of my Chevelle earlier this year, I decided to go deeper into the engine bay and give her the cleaning and detailing that I've been meaning to do since 1998. The first major component, as I work my way towards the firewall, was the Saginaw power steering gear box. In the past someone painted mine blue, I'm assuming to match the exterior color. I had had a leaking PS resevior, cracked at the return hose fitting, which has been replaced and have replaced the hoses, so I thought a rebuild of the gearbox was in order. After looking at the overhaul manual and doing some net reading, I came across a GOLDMINE of information on YouTube Many thanks to hutchhiperf on YouTube for this series of videos concerning the rebuild and adjustment of a Saginaw Power Steering Gearbox:

There are two types of kit you can buy, one is a kit of seals, for a lower level refresh, and the other is more a intensive, full-on rebuild kit which includes seals and replacement bearings. I opted for the full rebuild kit to do my job.
All in all the process isn't terribly difficult. I will call out a few areas that I found were different than Hutchhiperf's video series and things that found made my job easier.
