This is heading toward the right direction. This is Bontrager's top-drawer road hub with press-fit sealed bearings.. Likely the schmoe who sold them to you took something apart and failed to put it back together properly. I can't tell you what's wrong with it without looking at the hub. Take it to a Trek dealer or a mechanic who has experience with these hubs.
