My own personal diff came out of my 340i xDrive. Should fit all F2X F3X B58 chassis xDrive with ZF8.
Final drive is 2.81. Has 81k miles on it and the diff fluid was changed at 59K. Great condition.
If you wonder why this diff is out of my car, check out my review of Wavetrac LSD on the B58 discussion. This will be a great donor diff!
