Well too bad about the lttle one!!. . .glad he is ok, and it sure does sound like a spun hub...its no big deal,just make sure the seals are ok,i think they will be,just minor damage!!! im 100% sure,its meant to do that rather than do gear damage,its a replacement part thats very cheap,having a spare is always a good option bud....you will be ok,go to a reputable dealer,and you will be fishing by next weekend!!!! cheers
