Tires rubbing

Are these tires stock sized on stock rims? If so then you may want to check if the steering stop is still in place on the A-arm where the steering knuckle hits it. It sounds like it may have been damaged. The torsion keys are set to level out the vehicles ride height, they can be uneven depending on the way they are keyed to the bar and the weight on each side.

That is one of the hazards of lifted trucks with big tires, they can hit. Sounds like it will need to have some stops added to keep the tires from rubbing. The -45 rim is part of the problem as it makes the tire arc much more than it would stock. About the only solution is to install some steering stops to keep them from hitting the frame. Now if the tires are rubbing things like the inner fenders or the bumper areas, the only solution there is to trim those parts, but never cut or trim on the actual truck frame as that would make the truck unsafe to drive as it will severely weaken it.

It just turns a bit tighter to the left than right, actually common because of the way the steering works.
