Forgot to update this. I changed out the bearing before a trip on memorial day weekend. Turns out that the damn inside bearing was out of round....or had a couple of damaged bearings causing it to really look out of round. No spindle damage at all...no scoring, no nothing. I bought new bearings at NAPA, pulled out my green grease (I can't remember the name of it)....and took care of it. Not an issue since, and I check every hub at each stop just to make sure there isn't any issues. No idea what happened to that bearing. There was PLENTY of grease still in there.
