In some cases you could just reseal the power steering pump and reseal your pump or just replace it. (Honda reseal kit) And replace the belt to. If the hose is leaking also replace that. If the pump is noisy I would replace it.

When you do. Make sure you cycle the ingnition without starting the vehicle so you don't stave the pump and cause extra added wear on the bearing then would lead to probably having to replace the pump again or noisy pump.
