I've had three conventional-design Maytags in my life. Longest life was 22 years. Shortest was 14. Transmission was the culprit for all three at the end. At ten years I'll bet you're not there yet....could be wrong about that.

First thing I'd do is walk it back where you want it to be. Second thing would be make sure the feet are bearing firmly on the floor as close to equally weighted as you can get them.

Then run a load and see what you've got. I'm suspecting the legs may have come out of adjustment over time and made it impossible for the suspension components to compensate.

If that doesn't settle things down, next step would be to take off the front panel and check the suspension inside.
