One more important lesson is that the bearings need to go in a certain way. The speed sensor is imbedded in the bearing behind the dust shield. Although you can't see it, it is magnetic. Use a small metalic object, like a paperclip. And be wary, the first set of bearings I purchased did NOT have any speed sensors.
