Yes, in a prior life, I was one.

Won't do any good on a Maytag, a 17 yo model would be front serviced.

Try these things:

1. Check the self-leveling feet in the rear. Sometimes they rust-up and won't level comepletely. Rock the machine forward onto it's front and then let it drop back. That usually gets them repositioned.
   
2. If it doesn't have the leveling feet, make sure all the feet are screwed up into the base. These machines have a tendency to rock a little and, over time, the feet unscrew little by little and get too far out making it a bit wobbly on it's pins.
   
3. If your floor is wood, make sure it isn't rotted out under one of the back feet.
   
4. Open the lid and see if the basket is centered in the opening. If it is off center one of the tub springs is broken or a tub support arm is rusted out. Either way, you need to plan on buying a new washer.
