Yeah I think the rear is pressed as well, not screwed. I don't think it could be screwed on or off, because the wires wouldn't let it rotate.
Mine came loose a few months ago. My brother noticed it while the motor was out of the car, nothing happened while driving luckily.
I didn't see any threads on the endbell, so I just put some loctite on and pushed it back it. No problems since.

Maybe the 1521's are different? Because what's happening to BashOn's motor sounds pretty strange.
