I have a Kenmore 80 series washer. It made a grinding noise during the spin cycle then quit spinning. I checked the coupler and the plastic piece cracked. I ordered a coupler from appliancepartspros.com and replaced (got the 2 plastic pieces and the rubber piece). I tapped the plastic pieces on like the video showed. Then tested it. The first run, a whistling noise occurred during the spin cycle. So, I took everything back apart to get to the couplings and tapped the plastic pieces a little bit more. I gave it another test run, the whistle came then went during the spin cycle, but now smells like burning rubber during it. Any ideas or suggestions?
