Ride height setting confusion

When my dart was new, that’s on of the things I noticed about it, was the fact that when you crossed the centre line the car would want to dart over to the other lane. Took it back to dealer they said front end was right on spec. Drove well didn’t wear tires so I thought it was a quirk in the car. You just new it would want to do this.
Had to know it would want to do this
