I just replaced the power steering pump and now it is hard to turn at idle speed and still makes a very loud whining noise. If I take the car out of gear and then increase the rpm's to about 1000 then it becomes easier to steer but still makes a very loud whining noise. I have checked for leaks and checked the belt. All seems good. When I changed the pump I did bleed all of the old fluid out but it still does not seem right. What is the next step?
