Power Steering problem. Suggestions?

This summer I was out wheeling here in Colorado along a nice smooth forest service road. The road has occasional large rocks on it (fire road off Guanella pass to Argentine). I was doing about 25-30 and thought I could swerve by the mother of all rocks. Nope. I mashed it pretty hard with one wheel and completely lost my EPS. Hurt at bit from the whiplash of the steering. So I turned the machine off, and back on, and it came back fine. But ever since then it’s been weak. You basically don’t feel it all in 4wd, and in 2wd it’s sorta feels like it’s half there.

After getting a second 570 with EPS I now realize that there is something wrong with my first one, by comparison.

Any suggestions on how to fix or look at it? I’m not afraid to wrench anything. It’s definitely working "somewhat", but not full strength. Maybe 40%. Looking for that magical answer about tightening some magic bolt that will make it whole again. 🙂
