Dirtrider, Is that machine on a riser? I have seen the riser's play a drastic roll in adding to their vibrating tendency's. A lot of the time, the installers installed the riser's improperly resulting in more movement then desired, and possibly even welds breaking on the riser itself. I own one of these machines (MAH9700) and I, for the most part don't have much shaking out of it. It does have the upgraded board in it, is on a concrete floor, leveled perfectly with a slight tilt back, and does not have a riser on it.
As a service technician, authorized by Maytag the day they came out and now, I do know I have had a ton of service calls on these machine's in regards to their shaking. I usually bite my tongue, re-level, and explain how they work. I have found that the shake away pads, or grip tape from a skate board work great for steadying the machine's.
Just some tips that I have found work best on my washer.
1. Always split laundry into like articles. IE: Towels with towels only. Lighter weight fabric's with lighter weight fabric's
2. These machine's, like most run better with larger loads compared to small loads (less of a chance of all the articles to end up on the same side while spinning)
