Perhaps your ABS sensor is acting up. Possibly a bent hub? Also might be your ball joints/bearings
Just a few ideas. I've got the same chattering you talk about, drives me crazy, it's just I need to replace the pads/rotors. I sure hope that takes care of it

I feel your pain, hopefully you can get it figured out quick.
