Wasn't the belt!! Changed it anyway. Should have come here earlier. That mistake added several days to the repair waiting for a second batch of the right parts. Became a pro at taking the dryer apart and reassembling, though! Easy job, just take your time and mark your wires, if you need to.
Followed other people's excellent instructions. Clean out all the dust bunnies. Schematics were a great resource. Those and the prices made me a repeat customer.
The shaft of the Idler Lever wheel was the cause, but decided, since I had it apart, to spend a little more money and replace both Drum Support Rollers and the Roller Bracket and Shaft Assembly. They showed some wear, and the parts were very inexpensive. Make sure you have snap ring pliers with prongs that are smaller than the standard 0.40 to save some aggravation with the Drum Rollers. $5 tool. Total parts were less than $60. Probably saved $150+ in labor. Quieter than ever now. Thanks!
