The first thing I did was to unplug the dryer, I then removed the 2 screws on the lower cover,removed the cover, then removed the 2 screws for the door and un pluged the wires for the safet switch.and removed the door. I then removed the 4 screws that held the front durm support and removed it with the air ducting attached, I removed the 2 screws that hold the top of the dryer so that I could lift it as needed. I unhooked the belt from the tensioner and removed the belt and drum, I removed the snap rings and old rollers to give me access to the mounting bolts for the roller axels, and removed them. The drum had a flat spot from the worn out rollers that a few taps with a rubber mallet fixed. then usins the new parts reassembled the rollers, Installed the drum with a new drive belt. the bolted down the top the top, At this time I rolled the drum to make sure the belt and tensioner were ok. Then front support and ducting , the door ( remember to reattach the door safety switch wire ) and lower panel were bolted back into place. The dryer runs and sounds like new.
