Today I was messing around on my 2002 Polaris Sportsman 400 and was jumping it on a dirt pile which was probably not a great idea and one time I landed and the rear end locked up. I took it into the shop and started taking it apart. The drive shaft is turning and the rest brake rotor witch is connected to the drive shaft is turning but the rear is not turning and it it locked up. I pulled the cv joints thinking maybe I broke them but they were fine. Have any of you had this happen? I have not yet pulled the clutches to get the rest end out and apart but before I got in too deep I figured I would seek some help. Any suggestions on what to look for or what do do next would be great! Thank you in advance.
