Well I don't see what would be causing these problems. Can you look at these pictures and check if there's anything you see wrong?
Good range of steering to the left.
Horrible steering to the right.
Close tie rod rubs on frame.
Added spacers to prevent the rod from bending over the frame when nobody was in the cart.
Spindle steering bracket hitting the lower shock mount when turned to the right.
No apparent bends in the factory suspension components that I can see that would cause these wacky problems.
Frame looks perfectly straight.
