That is the 4.0 pulley u have, mine is the same, no lip. Now let's get a little more half-ass technical. You say whine. Could it be a buzz? That's a worn loose bearing noise. A consistent squeak? That could be a dry bearing noise, or belt(which I doubt is your problem, more of a squeal noise). A whine is more of a power steering pump normal operation noise, or the noise an alt makes before it goes, but yours is new. I had a good week of noise diagnostics in MMI Orlando, what a funny class that was. I forget a bunch of them now that I think of it, im gonna rip out my books and get some more later today.
Try to isolate the noise I guess, I wish I could hear this thing! You're sure it's on that side of the engine right? Sometimes rattles, like a/c clutch noises when they have loose parts, even the compressors sound like that sometimes when they are running. If I find my noise diag. sheet from school, I bet I would get it posted in the tech section, all my bike tech buddies and I diagnose over the phone all the time when we are stumped and people wonder what the hell we are talking about, but it always works.
Even a cellphone video helps man, put the microphone up to the ac, then the pulley bearing, then the alternator, all that stuff, at a nice low idle before the cooling fan kicks in. Even a set of internet ears can be of help sometimes Haha. Good luck man.
