My Maytag LDG490 is producing a distinct loud squeal as it turns, and I’m trying to isolate the cause to hopefully fix it. Even with the dryer turned off, manually rotating the drum produces the same squeal, but only when I push it in the same direction that the motor turns the drum, manually rotating the drum in the opposite direction does not produce any unusual sounds.
I’ve already replaced the Idler Pulley and the two support rollers, having initially thought it might be the cause of the sound(Plus they were a bit worn). In addition the belt was swapped out three or four years ago, and seemed in good shape when I examined it during the procedure. Any thoughts on what the real problem might be, and how to fix it?
What do the front drum glides look like? Part 24 in this diagram.
