I know this is in no way a big deal, I just like knowing what my car is doing and why- When I make a turn that'* a little on the hard side, it makes this whiney high-pitched noise. Never been told what that was.

If you mean by "on the hard side" -- all the way to the stop -- every power steering car does this, and you should probably avoid doing it.

I think it'* simply the power steering motor trying desparately to continue to turn your wheels when there'* no way they can be turned further. You're not cranking that hard, but IT is.

(If that'* not what you mean, then somethings wrong. First thing to do of course is check your ps fluid level and add fluid if necessary. Next might be to pop the serpentine belt and grab and check the power steering pulley for grinding, excessive play, hard to turn etc.

Maybe this is more answer than you wanted )

No, that'* great, thank you

Always makes me nuts when I see people desparatly trying to turn thier wheels tighter and the pump is whining away. Best not to do that.

not the pump but its the check valve in the rack and pinon alot our cars are plauged with the same symptom...does it need to be replaced...nah ive also experienced the same noise but only when in first gear making sharp turns tell if this sound like what your experiencing

that'* EXACTLY it, thanks
