19 year old Kenmore dryer. Disassembly was easy, just like the video. Using a shop vac on blow and vacuum, it took over an hour to clean out all the old lint and dirt. Rear Bearing: After cleaning it, I found the rear bearing intact and undamaged. Did not change it. The plastic/nylon bearing support looked worn, so it was replaced. Put fresh grease everywhere. Front Felt: the upper felt on the front panel also supports the drum and acts as a bearing. Replaced it. Foam seal for the fan: the foam seal for the fan was deteriorated from age. Already working in the area, so it was replaced. Belt: Wanted to replace it but had problems. Two separate replacement belts were an inch too long and would not tension. Used the old belt. Put the dryer back in the house for the test. Squeaks and squeals are gone and it runs like new.
