You most likely have a locking rear differential that is not slipping sufficiently to allow free turning. Ask at the dealer's parts department if they use an additive with whale oil. If they do, that will modify the gear lube to allow the clutch plates to slip easier. Lack of that additive, when needed, can also cause chattering when turning. That additive comes in about a four or six ounce bottle.
