This used OEM Audi driveshaft/propeller shaft, part number 4E4521101B, also replaces 4E4521101A, 4E4521101E, and 4E4521101F. Pulled from a donor A8 Quattro, this rear shaft transfers power from the transmission to the rear differential. A failing unit often produces driveline vibration or a clunking noise on acceleration or deceleration. It came from a 4.2L V8 or 6.0L W12 engine car; check your specific application.
