if the car is working good and goes straight most of the time then I would say maybe you are out of the groove when the car goes right. There are only a couple of reasons that a ladder bar car will go left or right at the hit. first is the rear is not square in the car. Second the front holes in the ladder bar mount are worn or elongated. Check both very carefully. Typically preload is not needed if the car is set up properly. My car I ladder bar and coil over. One other thing is I don't set the car up with the shocks on it. I have some struts that I made to go where the shocks mount the same length that I run the shocks. Set it up neutral with the struts then re install the shocks and set the ride height of the shocks exactly where it was with the struts.
