And thank you for your question.
Well as I'm sure you already know, this model is considered an "older" style dryer. Since your dryer is already disassembled, all you need to do in order to replace the drum bearing is remove the plastic sleeve from the rear of the drum. This sleeve is what they consider a bearing. See diagram below.
As for putting it all back together, just reverse the process in the link below and you should be in good shape. If you are still having problems, I have included a link below for the service manual that will cover your particular model.
I would also have a look at the front drum glides, and replace if necessary. Below is a link with an image for you.
I hope this answer helps you with your problem, and feel free to ask or add any additional comments.
