I’d call a driveline shop and see if they can fix it. Next I’d call the service desk at a polaris or can am dealer and see if they have any suggestions as who might be able to fix it. With all the shortages and delays some UTV dealer must have figured out a solution as people who pay 30 plus K for these things aren’t going to be happy waiting for parts.I am unsure who would fix the axle, I have tried a couple dealers and on line and its backordered.
