Well, here is what I noticed. Bought the quad used from someone who I know wouldn't touch it himself. Heck, I have receipts for a crank case oil change at the dealer! I was adjusting the chain and noticed that both my rear tires will turn a little bit without the axle turning. There is play between the hubs and the axle. The axle nuts are loose, is I can rock them by hand. I took the cotter pin out and tried to tighten them. They bottomed out and would not tighten far enough to allow me to get the cotter pin back in. The nuts aren't specific to one side or the other, ie the threads only line up 1 way? Any ideas/suggestions?
