Hey, I have an 89 5.0, it leaked power steering fluid, and long story short, I removed the Rack and Pinion to replace the lines. I have everything connected back up now and when I run the car, the wheel pulls all the way one way on it's own, then all the way the other way...I have no idea why it does this and would appreciate any ideas...my brother said something about maybe needing to bleed it, but we don't know how...
