There is another possibility. I've been a pilot my entire adult life, going back to when I flew in the Navy. I know I'm anal retentive, and mechanics have often accused me of finding problems that are not really problems. Although the hands off steering wheel shake is significant (1 to 3 degrees back and forth), it's not so forceful that most people would notice it if they had both hands on the wheel. I sometimes wonder if this is not normal on these cars and I'm just too hard to please.
That notwithstanding, I know the wheels/tires are good. Even I'm not unlucky enough to get three different sets of bad ones.
The runout on the hub is a possibility, and I'll check that.
As for the alignment and toe. The car tracks perfectly true, so I don't think that's the source of the problem.
