I have an old Lady Kenmore Portable Dryer that is squeaking this *constant* horrible high-pitched squeaking noise while it's running. Sometimes it gets louder and lower in pitch, but most of the time it's just the high-pitched noise and it's awful. :(

Which parts should I look at? Can I access them all by removing only the rear panel (I hope)? And can I use WD40 to lubricate whatever is squeaking?

I couldn't find anything for this specific model dryer, but it's extremely similar to my old portable dryer, a Whirlpool LE4905XMW1. Power cord is interchangeable, same overall design and placement of controls, etc.

Thank you for your help!
