1970 Dart Manual Steering-Car jerks left and right when trying to drive straight...
My truck is not the only vehicle that this happens to it was just the most extreme example of it in my personal cars, my wife has a Lexus GS that every spring when I take the 16" winter tires off and put the 18" low profiles which are the same overall height she mentions how bad it darts around on rough pavement.
I should have not used the term "in spec" to describe the suspension on the truck...it was 100% perfect.
Now I'm not really interest in going back and forth with you on tires and suspension, I just wanted to advise the original poster to try swapping over the front wheels and tires before he starts ripping the front end apart.
