Rear end noise

First of all I’d like to thank everyone who’s helped to get my rzr to the point it is (its a week away from being a custom build) forum worthy but after several searches online the rear end is making terrible noises. 2015 fox edition and 8 months old so out of warranty so I don’t to shoot from the hip, either wheel bearing or rear end. Just want to know where to start.
