repairmen said to buy a new dryer! or replace the motor! DO NOT EVEN THINK ABOUT IT!
It was the spring washer that was rubbing against the metal that was causing the very loud noise. The fiber washer that is used on the shaft on both sides of the roller had worn though and allowed the metal-metal contact. The fiber washer wore out! The fiber washers are very cheap!!!! in comparison to a motor or new dryer!
The drum rollers that support the rotating drum eventually wear out the fiber washer.
UNPLUG THE DRYER, DISCONNECT THE VENT
Remove the two screws on the lower front of the dryer panel, probably after you have tilted the unit backward. Remove the front panel by tilting out the bottom as there are two clips at the top. AFTER DOCUMENTING the CONNECTIONS - Disconnect the wires from the switch which is mounted on the front panel.
Carefully put the dryer on its back - be careful of the dryer vent to avoid damaging your floor or dryer vent!
Carefully pull the dryer drum up out of the dryer - as this is done the belt which moves the drum will fall away from the drum. I suggest before you remove the drum to eyeball the way the belt is tensioned and wrapped around the motor driveshaft, guard and tensioner. This will be the most difficult part of reassembling the machine. Some visual understand, maybe even pictures will help you later to get it installed correctly back into proper position... and it is NOT intuitive!
Once the drum is removed, the rollers are accessible. Rotate each and find the squeaker!
I recommend you replace the fiber washer on both, even though only one may be squeaking at this point (the other will be close to being worn out as well!).
I will not document the replacement of these parts as the assembly seems well documented elsewhere. I suggest you remain using the spring washer if there - as the after factory replacements do not seem to provide spring washers.
I would also suggest replacing the dryer drum belt, it is worn, after this many years, and putting in a new one will keep the dryer running for many more years. KNOWLEDGE IS POWER - USE IT
