I've got a set of DeeTrax wheels that are just over a year old and the freehub is making some disturbing sounds. It only does it occasionally and usually at speed, when I'm going slower than approx. 10 mph it's quiet. The hub sounds like it's binding up (almost a howling sound) and if I backpedal a bit it will stop. I've pulled it apart once and everything is tight although the body has a bit of play (very slight but noticeable). Any suggestions for this other than the obvious (new wheel)? The wheel coasts very well when in the stand if that helps any..
