RPM Dependent Whine Just recently I have noticed a little whine that is getting louder and louder as time goes on. If the car is just idline you can't really hear it but as soon as you give it gas you can here a small whine that is RPM dependent. The higher the RPM the more high pitched the whine, it almost sounds like a supercharger whine to some degree.
It is not radio feedback.
I suspect a power steering pump but I wanted to check if any of you have seen a similar issue.
Thanks guys.

Go out side with your car off take off the cap of your ps resovoir and cut the wheels back and forth to see if any air bleeds out. That can certainly cause a whine.

I have that same whine but mine sounds like it's coming from near flex pipe or tranny. It sounds between a squeak and a whine though not like how a ps pump or alternator whine would sound

My friend had the same problem on his 94 ford explorer(I know its a completely different vehicle) and he replaced his alternator and it went away. It was pretty loud to start with and only got louder the higher he revved it. Maybe a certain pully is starting to go.

I have what I suspect to be the same whine. I had the transmission replaced for unrelated reasons but still have the whine so I don't think its trans related. Also replaced the water pump for unrelated, still whines. I suspect the power steering pump as others do but it only whines sometimes and turning the wheel side to side doesn't make the whine any different.

Yeah I will have to check the fluid level tomorrow, and no I have not had the power steering line recall done at least since I have owned it. I guess they could be leaking, who knows.

Update:
Problem was the idler pulley right under the power steering pump. I used a pry bar to activate teh tensioner spring and then slipped the belt off the pulley, then I spun each pulley and found one to be really rough to spin, replaced it, re-installed belt. No more noise. $16.18.
15MM socket to remove pulley.
I almost felt guily only spending that much money to fix it.
