Looking at the photos, the driver side shows a spring with the gap; i.e. absolutely no preload. Looking at the passenger side, that spring appears to be compressed somewhat compared to the relaxed one. You should be able to just about turn the spring on the king pin by hand, to prove there is no preload. So I would suggest that you adjust the passenger side first to get that condition and then see how it compares with the other side. It may not be as unequal as you first thought. Peter B of SSL maintains that the important thing is to have both compression springs just moveable by hand, no matter how much thread might be showing at the top above the adjuster rings.
