First thought the problem was a stretched drum belt or bad idler pulley. Ordered a new belt and idler assy plus spring. Replaced those items with relative ease following suggestions obtained at this site.However, problem persisted and I now suspected a bad drum bearing. Odered the bearing kit and replaced same using the following procedure.
1. Removed the cover from the back of the dryer (held in place via two phillip head screws)
2. Pushed down on the idler assy and removed the idler spring to release the drum belt.
3. Inserted flat tip screwdriver between the top panel and the dryer main body in the front of the dryer to pry the top loose from the two retaining clips.
4. used phillips screwdriver to remove the two retaining screws (one left, one right) that hold the front panel to the main body of the dryer. (about a foot down from the top of the dryer).
5. disconnected the wiring plug on the top right hand side at the top of the dryer.
6. lifted the front panel slightly removing it from the main body and placed it to the side.
7. lifted the rear of the drum to release it from the bearing bracket and removed the drum belt.
8. Pulled the drum through the front of the dryer body and moved it to an open work area.
9. Reached into the Dryer and loosened the two
bearing bracket screws with a nut driver. Here's where another pair of hands would have come in handy. Holding the ground bar on the back of the drum with on hand, reached into the dryer and finished removing the bracket screws somehow managing not to drop the tiny grounding ball (size of a BB) Removed the badly damaged plastic bracket, grounding bar, and grounding ball and set
them aside to be discarded later.
10. Used impact driver with phillips attachment to remove two of the three screws that hold the bearing to the back of the drum (these are on the inside) The third screw's head stripped out and I had a very difficult time removing it. Had it not been for that, the job would have taken less than an hour.
11. I had my wife hold the bearing in place while I started the three retaining screws.
12. My wife also got behing the dryer and held the grounding bar in place while I installed the new bearing bracket . (this kept me from loosing the grounding ball)
I just reversed the rest of the procedures to install the drum belt, drum, front panel, etc.
The dryer works like new now, doesn't squeal.
Also replaced the on/off switch knob (just pulled the old one from the stem and slid the new one on.
