It mounts to the frame crossmember and supports the center of the driveshaft, reducing vibration and preventing excessive wear on U‑joints and slip yokes. The assembly includes a sealed ball bearing with a 1.968 inch bore, a rubber cushion, and a stamped steel bracket. Replacement is needed when the bearing becomes noisy, the rubber deteriorates, or the driveshaft vibrates under load.
