Dryer makes a loud squeaking/squealing noise while drying.
If the dryer model number begins with 417, the drum is supported by a ball bearing in back, and a seal and glides up front. Often, the bearing will become very dry, either from years of use, or from excessive lint blowing up into the bearing. If the bearing isn't cracked or otherwise noticeably bad, you can usually solve the issue simply by lubing the bearing with a high temp grease. While the machine is apart...(a major pain in the butt), make sure to check the condition of the seal and glides on the front panel, and replace the belt if it looks at all cracked or frayed.
If this dryer is not a 417 and/or does not have a rear bearing, it's best to get a maintainance kit (belt, idler pulley and drum rollers) and install all the aforementioned parts, as they are the most likely source of screech. Also, check the motor by spinning the shaft manually with the belt off....if that is squeeking, it's motor
