Dryer is making a high pitch squeak, sounds like a rusty swing. possible bearings

You probably have dry bearings from all the heat over the years. Unplug the unit and remove the back to expose the bearing and shaft. Using a light oil such as 3-in-1 squirt oil into the bearing and let it soak in. Do this several times and keep a rag under the bearing to catch any excess oil. Odds are that with a little lubricant the dryer will quiet down and work fine for many more years. This would also be a good time to clean any lint and dust bunnies out of the unit. Reassemble and test. You should be good to go. Let me know if I can be of anymore help.
