POWER STEERING NOISE

2005 Ford 500

Steering problem
2005 Ford 500 6 cyl Two Wheel Drive Automatic 85000 miles

Everything is quiet and normal when the car is cool, but after it heats up there is a loud whining noise whenever I turn the steering wheel. I also have tried suctioning the fluid out of the reservoir and replacing with a power steering " stop leak lubricator". This will keep it quiet for about two weeks then it starts up again. Does it sound like I need to replace the pump? Any other ideas? Thanks.

If this is the problem, why does the noise go away if I replace all the fluid in the reservoir with new fluid. Tis works for about wo weeks then the noise comes back.

Well that's a good question, but Ford did not explain the defect, only how to correct it, did you try the tests?
