Forced Induction Question for guys with KB blower

So I took my 2.1 KB off and sent it off for rebuild after noticing a bit a growling/grinding coming from the head unit. I did all the normal stuff like checking to make sure the noise wasn't coming from any other areas before assuming it was the blower. It wasn't crazy loud but I could hear it resonate in the car and it was slowly getting worse. So the re builder did find two bad bearing in the front of the blower and preformed a full rebuild. Anyways got the blower back and the noise is still there or possibly returned after about five minutes running (I didn't notice it right away anyways). It is not as loud as before but it's there for sure. I stuck a screw driver up to the drive snout area and I can hear a definite growling/grinding noise. I stuck the screw driver to all other pulley in the area and they are quite or normal bearing sound. My question is could this be normal? Do you guys with 1.7s or 2.1s have the same noise coming from your head unit? Maybe just normal gear noise? With shipping I'm into this rebuild about $830 so I'm a bit unnerved over the whole thing.

Sorry to hear about the hair loss. Yeah it's super frustrating to have a noise that could mean possible failure soon or just mean "yep its spinning normal". I'm glad to hear that I'm not the only one going nuts over this. Maybe I'll post a video. As for the noise in your video, I hear it but it sounds pretty normal. I have the 2.1 and I hear that noise sometimes as well.
