Yeah, seems to be a common occurrence. I loosened the rear brackets on day 2 because binding a little.
The front developed a growl at low/moderate speeds, probably just the tires that have a slight scalloping to them. I did a "quick bearing check" by trying to make the front wheels move, nothing.
When I get home I'm going to look everything over. (Yep, still not home yet, had work in Philly this week so went directly there instead of going home first and backtracking... via the Dragon).
