Where did you get that little bearing you used to repair the motor?

The front (well, actually it's the rear) end of the motor bears the greatest
load, having to support the impeller. That sleeve bearing almost always is
found to be hollowed out and the shaft rattling around.
I added a tiny ball bearing to that end of the motor. The fan is
significantly quieter. The rear (with the PCB) end sleeve bearing can't be
helped likewise because of the mating of the PCB. But it's worth it to
remove the board and lubricate it.

Good luck,
