Frigidaire squealing

Dryer Repair
,
1

I fix cars not dryers so im new with this, my frigidaire crown series model # F31C436ES0. Its making a loud squeeling, seems like it gets louder then quieter in a pattern every second, almost like a certain spot on the drum is making the noise. I removed a small square in the rear lower lt corner and removed a pulley freeing the belt. I then ran it and there was no noise. Im not sure if its the belt, pulley, or somthing with the drum, I also dont know how to remove any other panels to get better access in there. Any help is greatly appreciated, attached is a link with photos of the dryer and where I am at. Thank you.

I can hear the sound when I took the pulley off and manualy spin the drum. I just dont know what I need to replace in there, a bearing or guide? Also some information on how to get to the part and replace. Thank you

behind drum there is a support bearing. you will have to remove drum by lifting up on it from back of drum, it make take some force, remove belt first
