I would recommend replacing your bearings
Received my new MP10 quiet drive yesterday. It's no quieter than my old MP10, if anything its louder. I'm assuming there is a break-in period. Otherwise, I'm feeling a little ripped off right now.

MP10's are more prone to wet side noise (sounds like a rattle or rumble typically) out of the box but this noise does quiet considerably with a break-in period. This is because the bearings seat into one another over time.
When I first installed my new mp40QD I thought it was louder than it should be also. Turned out I had the wrong spacer on, even though by the measurments im pretty sure it was right. Either way I switched the spacer I was using and now its dead silent! I would try the other spacers and see if that makes it better or worse
