My trusty Frigidaire dryer works fine, much in part thanks to this website and part availability but it is now squeaking like crazy. I thought it was the belt tensioner but that that is less than one year old.

I popped the lid and noted the drum is rubbing the plastic guide connected to the front frame. I attached an image to show what I am referring to.

What would cause this to rub and what can I do to fix this?

As a side note, I replaced the drum bearing kit, belt, motor, blower housing assembly, idler pulley/tensioner, and heating element.
