bearings in the AC pump may be near stuffed putting more strain on it?

Are you tightening the locknut on the front of the idler pulley after you adjust it up?

The locknut is the nut on the front of the idler pulley. I'm sure they're the same as my 100 series.

that will probably be your problem if i was u i would pull your belt off and give the adjuster idler and the a/c pully a spin to see if they make any noise if they do replace the bearingd ;)
