A fully sealed ball type bearing provides support to the two-piece propeller shaft in the center of the vehicle. The bearing is housed n a rubber dampened insulator ring that allows the bearing some (minimal) movement. Once the bearing has been pressed out of insulator, the bearing must be replaced because the seal is damaged upon removal.
