Do-It-Yourself Story

Diagnosed the problem as an old/malfunctioning drum support roller. I had a problem finding a repair video or manual for my specific dryer (the Maytag Performa, MDE3500AYW, probably purchased around 2007-2008) which made proper disassembly difficult. But I finally found Appliance Parts Pros' excellent video here: https://www.youtube.com/watch?v=VTH4yJCoM0g The video was incredibly helpful, and made the repair simple. The most difficult part was removing and later repositioning the belt around the pulley, as it was hard to see what I was doing. Overall, though, it was doable. I tried the screwdriver trick (shown in the video) to get the snap ring off, but ended up purchasing snap ring pliers. Roller replacement was easy after that. I also took the opportunity to vacuum up all the lint and dust and other stuff inside the dryer. I also purchased the dryer drum roller axle, but did not end up needing it as the existing axles were undamaged. Our dryer now runs without a single squeak! It took about an hour to take the dryer apart, replace the rollers, and reassemble.
