The IMS shaft is 4 pieces that are lightly press fit together. The drive can separate from the driven components and when this occurs the precursor is wear debris like this. There's no way for this to get out of the shaft, until the shaft separates, or the bearing is pulled.

Or a hack installed the bearing and left debris from a previously failing bearing in the tube/ engine.
