Center bearings support the driveline when using 2 or more driveshafts. The center bearing is a ball bearing mounted in a rubber cushion that attaches to a frame crossmember. The manufacturer pre-lubricates and seals the bearing. The cushion allows vertical motion at the driveline and helps isolate the vehicle from vibration.
