Removing the rotor cover reveals no obvious damage to the rotor or stator. Someone please correct me if I'm wrong, but in this case the stator would be the metal housing and permanent magnets mounted inside. There is also a race (yellow circle) in the top for one end of the rotor (red circle).
The rotor contains the windings and copper contacts for the brushes (purple arrow).
WARNING: The end that goes into the housing contains a ball bearing (light blue circle) that is not captured and almost certainly will get lost. It can be stuck in the old grease inside, or possibly come out with the rotor just long enough to bounce on the floor and out of your life. I'm sure they can be replaced, but I am not sure of the size.

Yes. There are two ball bearings on either end of the rotor. I thought the one in red was captured, because it never seems to come out when I remove the rotor. I guess it isn’t!It's been a few months since I disassembled and I didn't have nearly the documenting skills you did unfortunately.
However, I found two bearings in my disassembled parts (not one) and, while I can't be sure, I suspect the second bearing goes in the opposite tip of the rotor (red Circle).
Could that be the case?
Glad to hear that!So this thread is very inspiring, and I have pulled my wiper motor and have begun diagnosing why the wipers are not working
It appears that the rod that goes between the main section and the smaller section, to connect both wiper gears, is frozen on the smaller side.
Any tips on how to get that unstuck? I opened it up, and the gears are fine, but the little Rod appears to be rusted on the inside
Holy Moses. That rod doesn’t need medicine, it needs to be taken out back and put out of its misery
