Dryer making screeching sound [video attached]

My dryer has been making a loud screeching sound for about a week which has gotten progressively worse. I took apart the dryer and the sound looks to be coming from the blower or the motor. This is my first time working on a dryer so any help pinpointing the problem would be appreciated. I’ve uploaded a video to youtube in case it’s of help:

Is there anything else I can do to narrow down what’s causing the sound? Or is it something obvious that I’m not aware of?

Most likely the problem is a bad blower wheel due to a worn out central hole. You will need a special pliers to remove the retaining ring (12 at the [B]diagram[/B]).
