Inline Power Steering Filter
As many of us 3.8 guys know, the power steering whine during the turning of the wheel gets old quickly. Since I'm one of those guys, my approach to solve this would be to drain and refill the fluid, then install the correct sized filter on the return line. These "inline" filters are supposed to use dense media to filter out tiny particles and debris in the fluid, as well as having a magnet that captures metal shavings. I believe the name of the filter manufacturer is Magnafine. Apparently they do similar things for transmission lines as well. Anyways, after leaving the magnetic filter on for a couple of days I'll remove it and clean the filter out, do this a couple more times until it comes back clean, then add a bottle of Ford's friction modifier (intended for LSD rear ends) to aid the lubrication ability of the fluid.
I had the original pump at one point which whined, and my replacement is no different. Doing a GM Saginaw pump swap seems a little too much.
