Wed6200sw works fine except its making metal draging sound

You'll have to take it apart and check the rollers and pulley and also check around the front of the drum,there's a felt seal there that i've found the drum cuts through it or something could be stuck in the felt,pull out the lint filter and remove the two screws in front of it,then get a screw driver and stick it in between the top cover and the front panel around two inches from the corner and pop up the top cover,check the drum to see if it looks like something is rubbing against it.if so unplug the dryer,disconnect the wire connector on the right side,and remove the two 5/16 inch screws that hold the front panel on.watch video
