Hey guys..having a wierd problem,

My front right wheel nut keeps coming off (After tightening it all the way)...and ONLY that wheel! I wouldnt like to use loctite, as it's a pain getting it back off again..specially if im in a pinch. Any ideas? the car only has like less then 10 runs on it, and no damage/scrapes/wear in that area what so ever..

Thanks!
