So I just wanted to give an update. Power steering appears to be fixed. Had the truck aligned yesterday. I replaced the steering gear box and there was a night and day difference. The old gear box felt almost like a manual gear box (when cold), but was precise. Of course when the vehicle warmed up, the steering was worse than a manual gear box especially with the wide front tires. The new gear box felt closer to a typical power steering gear box. The power steering fluid did not get hot so I was able to remove the gen 4 camaro power steering cooler. I will be driving the truck more often to see how it pans out, but everything looks on the up and up.

Glad you got it fixed and thanks for letting us know the solution.
