Dryer made loud screeching noise.

After reading all the other repair stories on Partselect, by the way thank you all, I removed the door, then removed the two security hooks that hold the top secure. Then I removed the front panel. I then marked all the screws on the outer door and shroud so I could easily put it back together. I left the all the wires connected and set the shroud and outer door to the side and removed the drum belt and drum. Removed the spring off the idler arm, then using nutdriver, removed the screw that secures the idler arm to the motor. Assembled the new idler arm parts and reversed the process to put it all back together. If I would have replaced the idler arm assembly the same time I replaced the drum support rollers, I wouldn't have had to do this twice! But now I am an expert repair tech on this particular model.
