My Repair & Advice
Took off oblong piece in the back of dryer that encircles the exhaust tube. With a flashlight and a screwdriver I was able to remove drive belt, remove idler pulley, replace with new pulley, and put the belt back on it. Took me maybe ten minutes. Not even close to the directions on here from other people but wow, much faster and requires a lot less skill. Obviously if you need to clean up lint build-up then do it the right way and take it all apart to mitigate fire hazards.
