While washing my bike I discovered my front axle nut was really loose. It was almost ready to fall off. I thought it was my axle cover, but it was the nut itself. Has any one else had this problem? I saw a few post on Bub's forum about it. Does anyone know the torque spec on tightening the front axle nut? I noticed the rear axle has a clip around the bolt after the nut to keep it from loosening. Is the front supposed to something simular? Or should I just use locktite and tighten it to the proper torque spec?
