#6194: Well, that's interesting
So, recalling something I read on-line during my search for answers on Wednesday, I stopped before getting on the highway on my way home today and let air out of the Jeep's front tires, until they were registering 32 PSI (warm, after a few miles of driving).
Result: amplitude of wobble around 55 MPH vastly reduced.
It seems that having your tire pressure too high can contribute to the wobble, even cause it in some cases. I've habitually kept the tires at 34 PSI cold, which goes up to about 38 PSI hot--and that's too much pressure, I think. So from now on I'll try to keep 'em around 28 PSI cold.
It's not gone but it's lessened, and I'll take any improvement I can get.

Heh.
