Is this normal steering shaft movements?

If there is any play in the steering gear, well, there should not be.

Since the track bar is not straight, measuring the angle that way is not correct - that’s why your angle numbers appeared so far off.

The angle you need is the line that connects the pivot points at either end of the track bar. Run a string - or something like a yard stick if that will work - from bolt to bolt and measure that angle. Since the drag link is straight, measuring the way you did is fine. Those are the two angles which should be pretty close.

If you post up some better pictures of the entire front end, taken from directly in front of the jeep, we may be able to help some more.
I’ll see if I can snap a pic tomorrow. I stopped by a “custom” car shop a few months ago and he told me everything up front looks good as far as angles go, but it won’t hurt for y’all to take a look at it too!

My RTC is only about 80% on my steering wheel too. I adjusted my caster up to 6* and it didn’t improve. I’m assuming that the play in the wheel isn’t allowing a full RTC.
