Well guys, took the calipers off last night and filed down the little channels the pads ride in and gently filed the "tabs" of the pads themselves, then put a very very thin amount of bearing grease in the channels. Also pulled the caliper slids bolts out and sanded them down gently with 500 grit, then lubed them up really good. Crossed the rotors (left side to right side, and vice versa) reinstalled everything good and tight.
...And no noise so far this morning (20 mile commute - mixed highway/city).
One of the pads looked like it was rubbing in the channels and I guess it was getting hung up in spots and the noise was it not seating right.
anyways all is good with the xploder now. cheers,
