Center Bearing Description

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