When you turn the drum is there friction at the point it scrapes?
It sounds to me like this is a bearing issue, have you checked the motor is still square and removed the top to inspect the wiring harness?
Sorry for the delay in responding, place you hand on the side as you spin the drum can you feel any vibration to see if its occurring at the side, secondly when you get the drum in a place where it makes contact move it back and forth to see if its binding in both directions.
With the washer unplugged, use your hands on the drum as you rotate it at the back and see if you can feel what is making contact with the drum as it binds, the fact its a cylinder makes me think it is not the drum but a bearing attached to the drum\motor.
The next step would be remove the motor and any pulleys and then spin the drum to see if there is still scraping.
Good afternoon, I havent heard back from you I just wanted to follow up to see if you required any further assistance?
