I have about two and half years old GE GFWR4800FWW (GFWR4800F0FWW specifically) front-loading washer. It has started making very loud noise during spin, and also when I turn the drum slowly by hand it seems something is pulled upward along with the drum little ways until gravity pulls it back down, creating a rattling sound, almost as if a chain would slide down on the outer surface of the drum. I've opened the back of the washer, and external to the plastic tub everything seems to be (at least visually) in order (shocks, suspension, etc.), so the problem seems to be inside the tub.
The next step would be to open the tub, which I haven't yet decided whether I want to attempt it myself. Based on the symptoms, I'm wondering how big bill I'm looking at in parts (and labor if I call someone to look at it), assuming something that could be tightened hasn't just come loose.
Thanks for any insights!
