Take the bottom front panel off, and take a look. Through it in a drain and spin cycle, and check it out. You could have a broken shock. Last week I came accross one where the customer said she herd a rubbing noise, and the drain hose that comes from the pump, all the way up to the top right hand corner, had come loose, and it was hitting the tub in a drain a cycle. You might also wanrt to take the top off, there are three screws in the back the hold the top on, and give it a good sherlock holmes, and lets us know what you find. Tom ApplianceEducator.com

it is most likely the rear bearing. on the age of your product, that is about the time the rear bearing goes. that is a very expensive repair done by a service tech. that part roughly runs about $340.00 bucks, and is not an easy job for a novice. you might want to have someone come out and take a look at to be sure. it is worth a service call to be sure. the estimate for that type of repair depending on where you live could be 500 to 600 bucks. i would have it checked to be sure, then for that cost, i would buy a new one. unless you feel you can do it yourself. if you click on your model # at your first post, go to picture 7, and look at part #8, and that is it. tom
