Loud screeching metal to metal sound. The roller and "axle" were worn out.

First I disconnected the power cord. Next the top of the dryer was easily popped upen with a screw driver by inserting it between the top panel and the front door panel. I removed the two sheet metal screws that held the door panel on the upper right and left sides. The door panel was easily lifted up and out and set it to the side (the door switch can stay connected, the wire is long enough). d I pulled the drum out from off of the rollers that hold the drum in place. No need to remove the belt, it stays in place. I reached through the drum and removed the two hex-head screws that held the roller in place ( I only replaced the left one) and added the new one. I pushed the drum back in place over the rollers (it snaps in place). I propped the drum up with a short screw driver to raise it off of the right and left drum glides (on the bottom). I replaced the felt pads and the plastic glides and set the drum back in place. I also replaced the felt ring (seal) that circles the door opening that the drum also glides on. I glued it in place in spots (with gasket glue). It folds back over itself and forms a double thick pad. You will see what I mean when you see how the old one looks. I replaced the front door panel and snapped the top panel back in place. I let the dryer set over night so the glue would set up. I turned it on the next morning and it is as quiet now as when it was new. Oh ...Jay (the husband) did the work not Jean the wife (her dryer, her credit card)
