Where should I get a power steering cooler at for these trucks

Yes I run only approved dexron atf in all these trucks.

How could the steering shaft be binding?

Check that shaft u joints are accepting grease and the needle bearings aren't rusted or broken, that means pulling the shaft and cups to inspect. If you do that replacing them isn't a bad idea. It could also be another u joint or knuckle in the steering column binding, it does happen. You will hear a clicking sound while turning the wheel.

Summitracing.com , small trans cooler and some high quality 2 wire teflon lines, braided stainless.
A line collapsing is something I would be sure wasn't happening before adding a cooler.

Is it possible the fluid is contaminated? Other than that it may be time to change the steering box.
