What part of it is binding on the screw? From your pics I can't really tell.
If anything, it looks like the links on the bottom should be turned up. I may be wrong.
Need more light under there to get a better pic. Can't see what's going on.
The tie rod (lower link) could be on upside down, but I cannot tell without seeing different angle. You have 3 pics, all taken from relatively the same angle.
The steering link from the servo to the knuckle is at a really steep angle. If it were me I would source some andled end links to fix that a bit.
Take a few more pics with a light shining under there, and from other angles.
