I have an issue with power steering on my 2000 V6.
It makes that oh-so-annoying high pitched sound like you're low on power steering fluid, but I know I'm not low because I am always reminded to check it to make sure I'm not.
It hardly takes any effort at all to turn so I don't think it's going out.
This has been going on for a long time but it has gone far past the point of simply ignoring it.
I had the tires rotated not long ago, that changed nothing.
My mechanic friend suggested I completely drain the fluid, flush it, and then refill it with clean, new fluid. I don't think this has ever been done to me car.
