Hello - you all were so helpful with a fridge a few years ago I thought maybe you could help with a dryer too?

I have a dryer that squeaks, squeals when running and it is getting worse!

I thought that if you could hear it, a tech familiar with these machines would be able to identify the issue.

Be prepared for some truly unpleasant sounds.

Which part to you think it might be?

Belt and Drum roller were suggested at the part site, but I'm not so sure.

Thanks for any help.

Kurt
