Maytag LDE9306ACE squeaking

Our Maytag LDE9306ACE dryer is squeaking. It sounds like it’s coming from the rear of the machine. From previous experience, I’ve already replaced the rear drum support rollers and axles. However, it has not fixed the problem. Also, the squeaking isn’t constant. It’s intermittent and irregular. What else could be causing this?

Replaced the idler puller, but it still didn’t fix the issue. Tonight, it stopped mid-cycle and made a buzzing sound when I tried to turn it back on. I opened the door, held the switch, and rotated the drum manually as I held the start button, and the dryer worked again.
