And now a 3rd motor with a similar problem. This is in a new to me used board I just bought. turns out it has a bit of motor growl and it looks to be the same kinda problem.
The growl:
The click, the play.
some dirty crap around the bearing this time:
inside bearing surface. ( lighting made the colors weird, black gook looks like ash)
magnets don’t look as bashed up as the original motors so this one hasn’t gotten as bad yet. was just noisy.
