This is the driveshaft center support bearing for BMW E60 545i/550i, E60/E61 535xi 6MT, and E63 645ci/650i. It replaces BMW part number 26127521856 (26 12 7 521 856).
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.
