[Dead Parrot]

Might check the races in the rotors. Went to get my rotors turned when replacing the pads and the guy noticed that the races were freely spinning in the rotors. Two new rotors and sets of bearings later, the problem was solved. At least it was discovered in the driveway instead of a 100 miles from home.

You did keep the bearings matched with their races? Mixing used bearings and races isn't recommended.

First thing I would try is loosening the spindle nut and resetting your bearings using oldpurple's method. Might be just that simple.
