Mark S Bonney Lake , WA April 06, 2020 My dryer was squealing non stop when running. Replaced the two main rollers, belt tension pulley and drive belt. One of the rollers had a bearing that had worn enough to not turn freely causing the loud squeal. I replaced the tension pulley and the belt as a preventative measure since I had the dryer apart.
