You beat me to it lol.
I did not even think about using bushings in the carrier bearings instead of using the center section bearings. This makes sense, though the center section could be off by a little bit (differing from the bushing used during the process you showed) and lead to the parasitic losses I mentioned.
However, there's not too much that you can do to avoid that. These things were assembled very precisely the first time around.
