Sound coming from new rotor

I replaced the passenger side brake rotor (and front pads) today, and now when I go over ~33mph I get this whirring sound coming from that side of the car. I packed the bearings (sat there for an hour with those  things), put grease all over everything, I don't think it has anything to do with the brake pads cuz it's just that one side, the other side I just replaced the pads and that was it. Also when I press on the brakes it doesn't do anything to the sound except that it kinda starts slowing it down, only cuz the car is slowing down. It gets noticeable at about 33mph, any slower and you really can't hear anything. also, I went on the freeway for a short distance (like 1/2 mile) and noticed that at freeway speed I couldn't hear it either. any ideas as to wtf I did wrong?  :dunno:

Nope. The big "pie plate" behind the rotor.

come to think of it that dust shield might have been bent by putting the caliper on it. would this also be known as the "backing plate"?

I would think it'd make a more metally sound, rather than a whirring sound, but I guess I'll find out tomorrow
