I did not realize this dryer had wear out parts. The Bearing Slides need to be replaced occasionally. I takes someone removing the front panel to view the slides for wear. We didn't find this out until the main Drum Support Bearing wore down to the point of loud screaching driving us out of the house when we used the dryer. Thanks to AppliancePartsPros.com I was able to look at the parts list to view what the Drum Support Bearing was supposed to look like, because the worn piece was to damaged. I was able to then make a shopping list based on the diagrams offered by AppliancePartsPros.com.
