I almost wanted to

when I saw this inside hub pic. I had to look up pictures. I had not realized the bearings were different than OEM. The black ring freaked me out.

After a few searches and looking at previous pics taken, I was cool.

The bearing must be multivehicle compatible.
While cleaning up under the X5, I found this long bended wire. I have no idea where it goes, if it goes on the X5. Anyone have a guess?
