Hey, you didn't write anything but just from my experience i would tighten those loose axle nuts. One of my hubs striped from the axle so that the wheel was getting no power i had to replace the whole axle. I noticed the hubs were jiggling around a little but didn't think anything of it becuase the nuts were still tight (i always was retighting them to ensure they wouldnt come loose). At one time or another they had to have been loose, it is the only thing i can think of that caused the hub to strip from the axle.

 

hey thanks i took care of it in another thread. raptor axle nut with set screws, i would never ride with the sprocket that loose!!!
