So....I swapped out to a set of front radius arms that have the stock bushings, providing stock caster. The truck definitely turns back to center much better now! I did take some of the advice to check out the trunnion bearing and this is what I can feel. The wheels are definitely harder to turn through that area that would be from about 9 o'clock to about 3 o'clock. Once you get past just passed center, it eases up a bit. I can certainly feel the difference as I cycle the wheels from full lock to lock. Is that the trunnions bearings, or is that normal? Or, is that just the hydraulics causing that?
