Not very common with recirculating ball steering gear boxes but it is possible to have internal leakage or a bent flow control valve. The fact that you have normal power assist in one direction proves the pump is okay.
On the off-chance something recently happened to affect the alignment, the steering could be harder one way than the other if caster changed from side to side. That would mean the I-beam got bent, and that isn't real likely.
