Could be worn or leaking internal steering ram seals.

Have you tried jacking the front up and seeing what happens if the wheels are off the ground?

If that's the case then it could be one or both the king pins is partly seized. To check disconnect the steering rods and see how freely they move. It could also be weak steering pump pressure. This shows more when steering right because as Jim says there is more surface area on the piston when turning left than right.

Bit of a silly question I know but, is the ram mounting bolted to the correct threaded holes on the chassis,if not that could give more throw one way than the other.
