I have a 36-year old Maytag A106 that is exhibiting a lot of problems lately. The washer shakes violently during its spin cycle but it never gets off balance or moves. The machine runs a bit louder than normal and squeaks throughout each spin cycle. After the machine completes its final spin, it makes a very loud high-pitched squealing noise. This high pitch squeal only happens at the very end of its final spin as the machine is shutting off and it is extremely loud. Even though the machine shakes and sounds terrible, it actually works well. Does anyone have any ideas what could be causing these symptoms? Since the machine still works, is there any danger of using it while it is making these strange noises? I am going to order a new Speed Queen to replace it, but I'd like to continue using it until it arrives unless there is a legitamite reason not to. I'm really sad to see this old machine finally die because it has been an excellent washer. I have been doing multiple loads of laundry in this washer each day for the past 17 years and it hasn't needed any repairs until recently.
