I have some numbers from TIS for the tool they use, but I'm told they would take a long time to get and be quite expensive. I didn't write all of them down, but the most important pieces are the receiver cup for the removal, which in TIS shows as 33 4 261, and the press plate for installation, 22 1 018. I have no idea how to translate those to actual part numbers...BMW seems to have followed Ford on this sort of nonsense! If I had those numbers I'm sure I could use them with any ordinary puller kit.
