BMW E46 Driveshaft Flex Disc and Center Support Bearing Kit

This kit pairs the two driveshaft wear parts that usually fail together on the E46: the rubber flex disc (guibo) at the transmission output and the center support bearing that holds the middle of the two-piece shaft. It replaces BMW 26111227410 for the flex disc and 26127501257 and 26121229492 for the center bearing.

Listed fitment: BMW E46 320i, 323i, 325i and 330i from 1997-2006, and the E85 Z4 from 2002-2005. Confirm the numbers on your old parts before ordering, since all-wheel-drive xi models and the M3 use different driveline parts.

On an E46 a cracked guibo causes a clunk when you shift into gear and a shudder when pulling away. A failed center bearing shows up as a vibration that builds with speed, and the rubber often tears so the shaft sags. Because both parts are the same age and the shaft has to come down for either one, replacing them together saves doing the job twice.

Bench notes: drop the exhaust and heat shield, mark the shaft halves and flanges, and unbolt the guibo from the transmission flange while holding the bolt heads so the new disc is not twisted. Press the new center bearing on with the shaft supported, and follow the BMW procedure for pre-loading the bearing bracket forward before tightening its nuts.
