can someone explain the bad axle story on the grizzly? I have a 2003 grizzly with 700 miles on it and a friend was telling me about them. now I'm worried about mine. how can you check them? I don't ride hard but I do ride double at times and I don't want anything to happen to anyone. should everyone just change the axle and be done with it? I guess some grizzlys never had that problem or are they like cars where certain ones have that problem? Plus is there somewhere on the grizzly to make sure it is a 2003? Thanks for your help.
