Loud Squeaky noise on GAS clothes Dryer

I have taken the Dryer apart and found that the Drum Roller guides were worn out and really deteriorated. I have ordered the the Kit to repair. I also noticed that the Lower Drum Seal felt was coming apart and I have the felt part number WE9M30. I did not see no glue holding the felt. Do you recommend that Glue be applied to hold the felt. I was reading on one of the posts that it is applied from the bottom to the top with the black part touching the drum. Is there a picture as to how the felt is applied?
