Sometimes, the shackle straps on a axle will "flip" and point down, rather than up. This can happen whenever you jack up the trailer, or go over a high speed bump, etc. This is how you flip the straps back to the correct position. Sometime you may need a pry bar to "flip" them if they dont go all the way on their own. Jack up the "good side" and the flipped" side should straighten out, then finally "flip back" R and P Carriages www.NeedaTrailer.com 815.357.3292
