Curious front end issue. Ideas wanted

All what you describe is normal. You cannot jounce the car with the tires sitting on the ground. They must be on something that allows motion like an alignment turnplate. So that's why the car doesn't settle until moved.

This is the correct answer. I’ve done the front alignment on my Duster and reset the torsion bar height after settling a few times now and what I found is 1/4 turn on torsion bar adjustment, drive around block, remeasure, repeat until you like the number. I tried that using the “jounce” method and added like an inch of height by accident. You have no issue, just overthinking how this suspension design works. It is not leafs, it is not coils, it does not work the same.

Some alignment shops are “scared” of torsion bars because they think they align differently. The torsion bars are only a height adjustment and affect alignment only if adjusted after the fact. After the ride height is set, alignment process is typical unless you ever take the weight off the car, then it’s a tighten hardware, lap around the block, back to measuring. More steps but not really… a Mopar can be aligned in a driveway with hand tools and tape measures, I have done it. And arguably easier, because “jounce” doesn’t work as well as driving to settle the car. Others may disagree but the end result is the same, just different ways to get there.
