This started with a squeaking noise on a 7-year old GE dryer. So I purchased a new idler pulley and the 4 glides (2 green 2 teflon) for the front bearing and decided since I was going to have the whole thing apart anyways, I'd order the rear bearing assembly with the other parts and replace it as well. I disassembled and reassembled the unit and my squeak was gone- woohoo- but now I have a damn scraping noise in the back of the drum. What was odd is it only happens for about 1/8 of the rotation. Upon further review, I could watch the drum move front to back to front to back to... about 1/8-1/4 inch as it rotated (it scraped each time it went to the BACK of the machine) so I took another step and since the front plastic drum support bearing had worn from the glides being bad, I ordered and replaced that as well as the felt strip on the bottom. I still have the same problem even though the front to back to front to.. movement has been cut in about half. That said, I can put light pressure on the back of the drum while it's rotating, pushing it towards the front, and stop the noise completely. I'm at a loss on how I could have introduced a new problem by adding new parts. Thoughts?
