ACDelco 84448548 GM Original Equipment Drive Shaft Center Support Bearing

The ACDelco 84448548 is a GM Original Equipment Drive Shaft Center Support Bearing designed to restore proper driveline alignment and function on GM vehicles with multi-piece driveshaft configurations. As a genuine GM part, it is held to the same rigorous engineering and quality standards as the component originally installed at the factory.

Drive shaft center support bearings are a critical driveline component — they cradle the midpoint of a two-piece driveshaft, maintaining proper shaft alignment during rotation and absorbing vibration that would otherwise transfer into the cabin. When this bearing fails, drivers typically experience driveline vibration, humming or rumbling noises, and in severe cases, driveshaft instability.
