Dryer Squeaks When Drum Turns

My dryer squeaks when the drum turns. everything works fine but the squeaking noise is very annoying. I’ve checked the felt seal and the drum belt and I can’t figure out what the problem is. Can anyone help me please?

hello,

Going through some issues with my dryer of which squeaky while turning is one. I opened front end and took out tensioner and cleaned completed with dawn dishwash stuff returned tensioner and so far it has been quiet as a mouse.

For Ruben:
Remove drum by lifting rear ball out of the socket. Use high temperature grease in the socket, that should fix it. Click on your model # for assembly info or parts.
