I would guess what @Mattman06 said above. The CV joints can plunge in and out of the axle cups. One is probably stuck in a little. I’d pull the axle out and make sure they plunge freely at both ends. The joint could have been damaged in the rollover. I believe that axle is on back order but they are rebuildable with Polaris parts. The parts to rebuild are in stock. Shoot me a PM if you end up needing any more parts.
