Very loud squeeks coming from dryer

I had to remove all screws from the back of the dryer, control panel, and one side. Pulled top off. Took out two screws that held front door panel on. Disconnected 3 wires into door and completely removed door panel. Disconneted pink wire from heating element then slide belt off drum as I removed the drum. Pulled off the old completly worn out drum bearing sleeve and replaced it. Replaced drum slides as some were worn through. Had a little trouble getting belt back on when I reconnected everything but for 50 dollars in parts and shipping I have working dryer, so I would say it was well worth the effort.
