Troubleshot and replaced the front assembly since the plastic tabs were worn down but it didn't solve the squeak. Bought the pulley and belt and waited a few days for them to deliver. Existing pulley had been worn down at the back of it somehow and I noticed a lot of black grime around it and under it. I watched the videos to replace both parts and clean the entire innards before putting it back together. So much dist accumulates form there. The replacement took about an hour.glad they have me the size for the wrench needed because I was struggling to find the right size. Once on and put back together it was the smoothest sound of it working again. Praise the Lord! Though we were liking drying the clothes outside ??.
