04 4x4 xe automatic High pitched noise, sounds like Chewbacca is under my hood (or like the old rusty gate swinging open at my grandma's house). Here's a video link: It does this whether I'm moving or stationary, turning or traveling straight, rpms don't really seem to do anything predictable. Sometimes accelerating from dead stop makes it go away briefly but other times it just gets louder. I've got power steering fluid in the reservoir, could maybe use a bit more but I wouldn't say I'm low or anything. It does seem to be a lot quieter after driving for about 30 minutes, but it moaned the entire time I was driving to work and back (heard when going slowly and parking). Thanks!
