Well, I lifted the top and took off the front door panel and did a good vacuuming clean out. Definitely needed it. I popped the belt off the motor pulley and removed the drum (and vacuumed more, of course). I was able to turn the dryer on w/o the drum (probably not recommended) and noticed a very quiet sqeaking sound that seemed to be coming from the small motor pulley, but not too loud (I was thinking great, the motor is done). Of course, since the drum wasn't in, the two rollers weren't turning. But I couldn't get it to make the very loud squealing sound. I put the drum back in and hooked everything back up and dried a load of laundry. The loud squeal came back and I listened to the outside and the loudest part of the noise seemed to be coming from the back of the dryer, close to where the rollers are located. So I will order the tollers and see if that fixes the problem. I figure at $33 before shipping on that website, I might take a chance and see if it's the rollers.
