Tracking down engine whine (video)
Hey all! So I haven't had working power-steering for about 6 months. I was too cheap to replace the pump and didn't really mind it. But recently it developed a whining noise, RPM dependent, similar to when power-steering reservoir is low. So I decided to go ahead and replace the pump. Well, I have power-steering now, but no change in the noise. Is there an easy way to eliminate other options?
It doesn't seem to be coming from the drivers side, so I'd like to eliminate ACE, PS, and AC. Is there a way, besides throwing money at new parts, to figure this out better? I just really hope it isn't the water pump. I've tried the screwdriver method, but it hasn't seemed to help me yet.
Hopefully this video will help:

You can get a stethescope that has a stick on the end and stick it on different components. You will know immediately when you touch the one that is whining. If you do not want to purchase one of these, large screwdrivers and a few longer extensions for a wratchet will work as well.
My alternator sounded like that and I just took it apart and replaced the bearings, but to be honest any of the components with a bad bearing can sound like that.

I use a wooden yardstick, very effective. It keeps you further away from the engine roar so the sound is more distinct.
EDIT: I've had alternators sound like that, but I'd verify with some sort of Stethoscope/Yardstick before spending money.

So, when I took the load off of the power steering pump - a brand new pump from All Makes by the way - i had NO more noise in the cabin in the rover.
Yes, could be a pulley too.
I just have been putting up with the sickening noise.
I tested for it by loosing the belt.
This is not a safe procedure to do it dynamically so be careful
