Nolan K Virginia Beach , VA July 09, 2016 Appliance: Maytag Electric Dryer MDE8757AYW Maytag Dryer Mde8757ayw: Squealing when first turned on. How to replace Drum Support Roller. Replaced Drum Support Roller (only one of the two bad), Dryer Drum Roller Axle, Tumbler Bearing Kit (again only one was worn), Dryer Drum Belt (since it was apart anyway). Hex Nuts and Fiber Washers as needed. Hardess part was getting belt back on idler, found pushing it up and securing with a wire tie, before putting drum back in was the best way. I'm 70 years old and it wasn't that bad of a repair. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
