The center support bearings (CSB) joins the two halves of the driveshaft together. There is a sealed set of ball bearings with a rubber mount and frame bolted to the chassis of the car. At some point either the bearings or rubber mount will fail, even under normal use. Symptoms include vibration or a whine/hum noise coming from the center of the car, and an audible clunk especially when pulling away from a stop. These are signs of a failing CSB and you should plan on replacing it soon. The CSB is an inexpensive fix but labor intensive so professional or experienced installation is recommended.

This is a center support bearing manufactured by Rein (CRP) Automotive - an original supplier to BMW for many engine and driveline components. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved.
