Hey Ryan, from what you describe, it sounds like your rear bearing is getting noisy. The bearing is located at the rear of the tub and is not replaceable by itself. The entire rear drum gets replaced. The good news is that most of the 9150's have a 10 year warranty on that tub. You can go to servicematters.com and click on Warranty Summary Guide, enter your model and serial # XXXXX as printed on your machine and it will tell you what warranty you have. It can also be found in your owners manual if you have it. The labor won't be covered if more than 1 year old, but at most that would run you about $150-200. Kepp me posted....thanks! Kelly
I also was skeptical of this site when I first came across it, but there are some very knowledgeable techs here!!
