Dryer was squeaking, it's 15 yrs old. Went on Appliance Parts Pros, for information on the causes of the squeaking. The causes listed were belt, rollers & or Idler pulley. I took the dryer apart, not very hard but you need space to remove the front panel & drum. Inspected the belt, rollers, Idler pulley & Felt Drum seal, all needed replacement. Ordered the parts from App. Parts Pro, they came within 3 days, with instructions on how to replace these items. AppliancePartsPro, made this repair, simple, with straight forward information & instructions. The dryer is working like brand new, BUT, MOST IMPORTANT, WIFEY IS HAPPY, so I'm happy. Thanks
