My dryer started making a horrible high pitched squealing noise, gradually increasing in volume over a month or so until it was intolerable even being on another floor. Initially, upon reading online, I thought that the rear bearing might be going out. I unscrewed the top of the dryer, and removed the front. Turning the drum by hand, I could reproduce the noise, which sounded like it was coming from the back of the dryer. I opened the rear access panel and turned the drum again by hand to pin the noise down - it sounded like it was coming from the tension pulley or maybe the motor. I pulled the belt off of the drum and spun it again, no noise. I turned the motor by hand, no noise. My best guess was that the old belt was slipping and making the noise (it was in pretty miserable condition), but I decided to buy a pulley assembly in addition to a new belt anyway. Installing both of them fixed the problem (I didn't try only installing one, however, so I don't know which one fixed it).
