How to Troubleshoot & Replace Ge AP2621539 / WE1M461 O Ring

I replaced everything was very easy work's great now 

I replaced the slide bearings a few years back. A few months later the rear bearing started to go so I replaced that one. Bad idea. Replace these two at the same time. The wobbling from the rear bearing failure caused accelerated wear on the slide bearings. Without the money to fix it I ran it as it was. Another bad idea. The drum not only chewed through the slide bearings, but eventually the assembly as well. I replaced the whole assembly and rear bearing at one time a couple days ago. It was really not that hard, though it did take a full day due to a stripped screw that eventually had to be drilled out. Would’ve only taken about an hour without that issue and now it runs smooth and quiet. 

Selected and ordered parts from online drawings. Watched videos showing how to make repair. Replaced worn parts with new ones. Suggested improvement: Videos didn't show my model (I know there are many models, showing all is probably not possible). In case of Felt the video showed a Maytag dryer when my model was GE. In my case Felt had torn and dislodge from slot so I didn't know exactly how it should be installed. A simple picture of the installed Item would help. Also the parts list should give number of each item required. The bearing slides require 2 of each type, the drawing only shows one and the parts list doesn't say 2 required. Other sites did specify this. 

Now it works perfectly with your part and especially your videos help. Thanks a lot 

Took it apart and replaced with new parts. 

Bought the parts I needed and watched the videos. Now my dryer is normal again. 

New Slides, Bearings, and Felt Seal. 

Replace the belt and rear bearing sleeve (worn), plus the front drum bearings and bearing slides (worn). The worn rear bearing sleeve and front drum bearings were very worn and caused the dryer to shake and vibrate which I believe wore out the belt prematurely. Once the parts were replaced the Dryer ran better than new. Amazing. Used the Video repair guides to get my education on how to do the repair. I spent $110 on Parts, and Saved over $200 in Labor! And over $600 had I just bought a new Dryer. AppliancePartsPros.com has a customer for life. 

Felt trap duct, drum belt, ring, ring bearing sleeve. 

Changed the bearing slides, rear drum bearing sleeve, and the belt since I was there.
