I had to replace the one wheel bearing, unfortunately. As mentioned above, the "splash guard" (with the clip that the ABS connector attaches to) that get sandwiched between the bearing hub and the steering knuckle was missing thanks to a previous owner, so the wiring was chaffed pretty much right through at the clip (on the wheel bearing side). I was hoping to do some sort of repair, but one of the wires was severed elsewhere too. So I put the bearing in hoping that it would just fix it and not be some band-aid fix that could fail down the road.
I do not want to (and have NO plan to) keep dropping wheel bearings in at $152 (after tax) each, thus the reason I am thinking that a scan tool will at least help me pinpoint a direction to start from here since some basic visual inspection didn't reveal anything obvious.
