so i dropped my 04 X on H&R springs a couple of months ago, got some M45 wheels to go with it at the same time. now, there's some "chirp" type sound that seems to be coming from my front passenger side when i let my foot off the gas and just let the car cruise. i don't know what word to use to describe the sound, perhaps a squeal? it basically squeals, or chirps, with every rotation of the wheel.

maybe wheel bearings? any ideas?
