I FINALLY got my sportsman back from the shop today. This is the first ride with the new cam, carb, exhaust, wheels & tires. Me and 2 of my friends went riding, hills/trails/creeks, and the ol' sportsman just aint right. When slowing down, the rear end shakes and vibrates BADLY, its only when Im slowing down from mid to higher speeds(20+). I dont know why its doing this, I have the rear axles timed perfectly according to the polaris dealer. The rear hubs are tight, everything has plenty of grease. The rear brake disc is loose, I have tried tightening it, cant get it, but im sure thats not causing the vibration and shaking, just the annoying clanking sound. Any Ideas on my problem?

 

I did some more investigating today, I jacked up the rear end, set the brake, and found out that theres a lot of play in the right axle where the 2 halves come together. I'm not sure but I think the only movement that should be in them will be in/out, not forward/back. I think its causing the vibration during deceleration because the inner axle isnt being held tight against the outer. Does this sound right? because I have also noticed that if I keep on the throttle a little while Im slowing down, it doesnt do it. I hope this is it. Would there be any other ideas or possible solutions?
