It is challenging to see if the dimensions are actually different in terms of the bolt holes location for the front two and rear one.
BUT...when you look at RealOEM P/N's, the rear axle carrier is the SAME in the 4.8is and any other E53.

As a side note, there MAY BE a difference in your CV axle drive-flange. I had this issue on mine when I did the swap to 3.64 rear diff. All I did was swap the drive flanges out that was compatible with my rear cv axles, and voila.
You can see slight differences between a 4.8is diff and non. |
Thank you for this, that is exactly what's different in size.
However, the medium case diff in place of the large case (stock) causes about an inch and a half of space between the axles and the diff itself.
So do I need 4.4 axles? Or do I swap parts off the 4.10 large case to make the 3.64 medium case work?
