A stiff part of the steering when turning back and forth can be verified as a steering gear or gear box as the shade tree mechanics call it, if it is stiff in the same place every time the wheels are turned. If the nut that holds the torque preload was adjusted accidentally that is definitely the problem.
The other possibility is a sticking steering mechanical component. Outer tie rods can rust internally and cause a stiff turning problem, but very rarely.
