This Genuine BMW driveshaft center support (26121229243 / ES#2815047) is the bearing carrier that suspends the middle of a two-piece driveshaft, isolating drivetrain vibration from the chassis. A worn or cracked rubber isolator in this mount is a common source of a droning or vibrating noise from underneath the car at speed.

Fitment: BMW E39 540i (M62 4.4L) and E52 Z8, including the Z8 Alpina Roadster (M62 4.8L) and standard Z8 (S62 5.0L) — not the 3 Series E36/E46 chassis or 325i/328i/330i/M3 models on the original listing.
