Serpentine Whine

Serpentine Whine
So I just notice that I am getting a whining from my front accesories... sounds exactly like an eaton type supercharger. Only happens after the truck as been driven and warmed up, whine is directly related to RPM.
I havent removed the belt yet to see if the noise goes away. If I get the truck warmed up so it starts whining, can I take the belt off and re-start the truck to see if the noise goes away(isolating the belt/accessories)? I know you can do this on most cars, but I dont know if this could cause a problem with the TIPM?
Otherwise I am guessing it is one of the static idle pulleys, or the pulley on the tensioner. Or could it be the belt getting warm and stretching causing the noise? Either way I think I am just going to change all 3 idle pulleys and the belt... its time anyway with 95,000 miles on the truck.
Does anyone know the part numbers for the 2 idle pulleys and the tensionor pulley? If I remember right, one idle pulley in on the top of the motor and I think one bolted to the water pump(I changed the water pump 15,000 miles ago)... are both those pulleys the same part number? I use Rock Auto, but they have a ton of pulleys listed.

What kinda problems you having? Does your sound change at all when you turn your wheel?

I removed the belt and drove my 03. Shouldn't be a problem. Just make sure you don't over heat it. I could drive about 45 seconds before the gauge started to spike upward. I found the A/C clutch bearing to be the problem. Dealer was trying to sell me an alternator.

Honestly, my truck has done this since it was new. I know exactly what you're talking about. Stay under 3500 RPM or so and you never hear it. But say you nail the throttle, it starts to SCREAM like a roots blower in high RPM.
I tried for a while to figure it out (not that hard), but never did. I've replaced both idlers & the tensioner pulley, and a new belt, but it had no affect.
Like I said, my truck has done this since it was new. It's now 7 years old with 145k, and still does it. '06 Ram 1500 HEMI QC 4x4

I changed to a new belt last night. When I took the original off and spun everything and everythin spun fine. PS was the hardest pulley to turn but it turned smooth, just with more resistance. I put the new belt on it and I didn't really hear the noise anymore, maybe the truck needed to run longer. I used a mechanics scope and all the pulleys sounded about the same.We'll see
