I would try flushing the power steering fluid out, and put new in first, as its probably the cheapest thing to do.
Just remember these cars use DexronIII type ATF and not regular power steering fluid.
I had an issue with hard to turn steering wheel and I added a splash of Seafoam brand Trans Tune that I picked up from AutoZone to the fluid and it instantly helped out and kind of band-aid' the worn pump I have.
