I just read above 06. Should be x-drive and not compatible with mismatch. I think bmw says 1% maximum difference between axles of 1%.

The correct part number (33107510656) is on a sticker on top of the diff (you''ll need a probe camera or a mirror) and will include the diff ratio (4.10): -

It was casted on the diff next to the right cv. I guess should ignore that. Just curious, should almost all post facelift models with 3.0i have a 4.10? Mine is 2006 production October 2005.

Did you ever have drive train "shudder"? I've seen A couple examples of x-drive with just slightly different sizeb tires made the DSC very mad. Made the car shudder until they replaced the tires.

No, car drove fine prior to this. Just the howling at 60 and the clicking which was 100% the front splines.

I did have wheel spin with the 4x4 light flashing in the rear during the winter but its just because the inside of the rear tires are bad cuz of the toe. Was gonna replace them soon.
