I have a Maytag Bravos MCT washer model mvwx655dw1 that is two years old. On spun cycles it spins out of balance causing it to shake and knock loudly. I replaced the suspension springs and it made no difference. I called a repairman out sho changed the hub and it seemed to be no different.He came back again and replaced the inner tub and it is better but still does it just not as often. Is there anything else to look for?? He said that the transmission would be his next guess. Is this something I should fix or just keep buying a new piece of junk every two years? Thanks for any help that anyone can provide.
