My Repair & Advice
I figured it would be one of the drum rollers, so I went to Appliance Parts Pros website to order a roller before disassembling the dryer. I saw they had a kit available with all 4 rollers, belt, and idler pulley. Parts arrived the next day and were Whirlpool brand name (came with instruction sheet but the sheet was only high level, not step-by-step). As expected, lower rear roller had separated from the bearing. I replaced all rollers, idler pulley and belt. I also vacuumed the 9 years of lint buildup from inside the housing and all cracks/crevices. Works and sounds like new, all for under $50.
