Replaced the rear Drum Bearing kit, Glide Drum, Upper Felt and Idler Arm.
These were the most recommended repairs from AppliancePartsPros.com, and since I had the dryer apart, I chose to replace all the common wear parts.
The hardest part was figuring out how to take the top off... there were no good images or descriptions. For my model, there are two spring clips on the front above the control panel and top which need to be depressed with a flat head screw driver.
