I have an old JD 1032 snowblower. It squeals like a stuck pig when the auger is engaged. I took the thing apart and on the back side of the housing is a triangle piece which has what looks like a metal bushing pressed into it. The parts diagram shows a bearing and bushing. I am wondering if there is a bearing inside the triangle piece behind the bushing. Nothing wants to turn but I would think there would have to be a bearing there. I have taken other machines apart in a similar manner and there has always been a bearing but it was good sized and very obvious.
