Couple things to check...
1) Check your snubber ring. This little creature sits between the wash mech and the base of the washer. If the ring is too worn and/or the base of the washer where the ring rubs against is contaminated, the mech will grab the base and transfer vibration. Remember, the Dependable Care Maytags use lubricated pads while your Norge/Magic Chef made Maytag (born in Herron, IL.) uses a DRY nylon/teflon ring.
2) Check your rear leveling legs! This is the simplest thing to check. The rear legs work on a see-saw kind of arrangement about the same as a Whirlpool washer and they can easily jam. Tip the washer towards you. You should see and hear the rear legs move and when you set it back down, hear the clunk of the rear legs self adjusting to the floor.
