I finally have closure on this issue.

Last fall I replaced drag link, tie rod ends, track bar, alignment...problem was reduced but still there.

Since the problem started, I've had to put a couple pounds of air in the passenger side front tire every couple months or so. Didn't think much of it till I was rotating the tires and found a massive nail in said tire.

Had the nail removed, tire repaired, and no more wiggle/wobble!!
