Need a little help here the weekend my left rear wheel stopping spinning, I am not sure if it is the axel or the differential (hoping its the axel). The axel has play close to the differential but does not seem to have been twisted off. The video I attached the hand brake is applied and the bike is in neutral If I spin the wheel by hand the axel turns and also does the driveshaft. But when the bike is in gear the rear wheel does not turn leaving me to believe the cv joint is stripped close to the differential. Any help or input is greatly appreciated. The bike is a 2005 sportsman 500.

Thanks Jake
