Yes, I've heard this one too, and the article I read in no way
denied it.

Gravitational interactions with other planets, mostly Jupiter.
The article didn't explain how, and I don't understand such
subtleties of rotational mechanics. I will point out the the
earth's axis of rotational does wobble, as it is, so something
is enough to push that axis around.
