GX470 steering stiff (1 Viewer)

Hey, I have an GX470 04, I have had an issue with steering for the past 2-3 weeks, the steeing stiff when you move like 1 full turn to either side, we changed rack, pump, intermediate shaft (this did a lot improvement) but issue still persist, not as hard as before changing the intermediate shaft, my next suspect is the steering column, but before going into that route, is there any test we can do confirm? does the the column has any Ujoint or something that can cause this?
