powewr steering problem wheel hard to turn on 1993 Toyota Camry

my steering wheel is hard to turn,the pump was whining so i replaced it. but the steering wheel is still stiff, could the rack and pinion cause this?

yes it could be the rack but check for ps leaks first
How could i check the rack?When the wheel is turned one way the fluid in the resivour goes down then in the other direction the fluid goes up,i dont know if this is a clue or not,I dont see any leaks
