My Kenmore Elite washer, model #110.23032101, is 12 years old. I bought it because it was guaranteed not to vibrate or move while spinning. It started vibrating very loudly and "walking" about a month ago. It is not a leveling problem. The whole tub shifts up to 1-1/2" in any direction if I push on it. I quit using it a few weeks ago out of fear something would break inside. Can you help me? I don't want to call a tech to be told it is too costly to fix and just buy a new one. Thank you.
