I've got a 2005 Polaris Sportsman 500 HO AWD on demand and I'm having problems with the 4x4 left side will engage right side will not I have fixed the ground problem and I am stumped if anybody has advice please message me thank you

 

Most common problems were the plastic roller cage cracking and armature plate becoming magnetized causing one side to lock up. Plus output shafts and bearings need to looked over also.Even if the roller cage hasn't cracked,replace it with a billet aluminum one before it does.Plenty of them on ebay and amazon. Here's a similar gear case from a Rzr.
