The dryer was making a "horrid" noise while tumbling. I ordered the rear drum bearing kit and replaced it. When I removed the drum, I noticed that the Idler Pulley had lost one of its flanges and the drum drive belt was rubbing on the belt tensioner. I replaced the Drive Belt Idler Pulley and as a safety measure replaced the drive belt. The drive belt was showing its age. Appliance Parts Pros shipped the new parts quickly and I repaired the dryer twice in that weekend.
