Question about Polaris ATV
They are magnetic activated check the small wires coming down along each shock to see if one is broken. If not sounds like cv joint came apart and needs rebuild

It is either your inner or outter rear CV joint! replace drive axle assembly which is cheaper than replacing just the joint! sometimes repacking the joints helps but only sometimes

I have a 2004 Polaris 500 with the same knock. Tear down shows tight lower rod bearing and wrist pin. The piston fits tight at .0015 clearance. The balancer seems OK also but did not split the crankcase.

Yes it is vacuum activated, I would check your vacuum lines for cracks and make sure they are snug. I would also check your air filter. If all looks good and it still happens I would clean youe carb because some dirt, rust or debris could have made its way there causing the inlet needle valve to be stuck open or it could be worn. Hope this helped
