I replaced the dryer belt drying to resolve a loud squeak. After the belt change the dryer still had a loud squeak. After reviewing the videos on Appliance Parts Pro I decided it was not the expensive to replace the rear drum bearing, front drum support, bearing slides, and the idler pulley. With the guidance provided by Appliance Parts Pro it was easy to rebuild the inside of the dryer. It took me about an hour to do everything. The dryer now works great.
