Default Loud annoying idle with VIDEO

I've had this loud buzzy-like idle for quite a while. There'* a few noises that seem to be different, but it'* hard to tell. I thought the SC coupler was bad, now I'm thinking the tensioner pulley? I checked the SC pulley for play, and I don't think there is any. It seems tight every which way. There'* only a slight 'tick' noise turning it left to right, that may be normal. I don't really know though as I've never had comparisons.

Also, though possibly unrelated, when I drive my transmission seems very whiney, but it'* always had some whine since I got it in April.

Anyway, here'* a video if it helps.

EDIT: Most would already know, but for those that aren't sure, this is not the HB.

Oh yeah? I didn't even think of that. I figured I'd have noises while steering as well, and I don't THINK I do...or I can't hear them over the loud dying wheel bearing and my music.

I mentioned my tranny whines, but couldn't this be the PS pump instead? It'* very audible whine/whirr while driving and accelerating. It changes with speed. I didn't check the other pulleys besides the SC for any play. Maybe my tranny really isn't making the noises I thought it was...?

Take the belts off, maybe one at a time, see if you can narrow it down to a certain set of pulleys while running. Then spin them by hand.

I will try this tomorrow. Thanks Pat for making me realize it could be something else.

What exactly am I looking for when I spin the pulleys by hand? Off hand, I don't even know which one is for the PS. Off to find out....

EDIT: I'm guessing the PS pump is a pain to get to...in the back?

Grinding, play (I think the PS pump will have play regardless), catching. None are too difficult to reach.

Spin the pullies.. you will feel the grind or hear it.

Like a bad alternator.. squeak squeak squeak....I think if that goes too long, you won't have to guess which one it is.
