Strange squeaking noise
 
Can anyone help identify the squeaking noise in the attached youtube video? This is on my 1977 240D. I'm thinking its coming from the power steering pump area.

Power steering pump, water pump or even the AC pump. Very hard to tell from the video.

Spray a small amount of wd-40 at each pulleyed drive ,one at a time then test , see which one makes it go away .Very likely youve got a piece of an old belt wedge somewear ,does it smell when you rev it up like smoldering rubber?

I'm going to remove some belts and see if I can narrow it down.

No smells at all. Won't the WD-40 ruin the belts?

The noise appears to have the same frequency as the rotation of the power steering belt.
