Sqeeky / sqealing dryer

Took off face of dryer (two lower screws below door in front) and then removed the drum which gave me access to the idler arm and idler pully. Vaccumed the interior to remove dust and lint. Replaced idler arm and idler pulley assembly. Replace old belt as drum was reinstalled. Opened rear access panel to complete final routing of the new belt over idler pulley and drive motor. Turned the machine on to check repairs and function. Closed rear access door. Pushed dryer back into place and re-leveled machine.
