The bar should **** the LCA toward the ground so when the cars suspension is loaded it is putting tension on the bar. It will naturally want to install and hang in a very downward position and will take a bit of force to lift it and the spindle up to meet the hanging UCA, ie. with a floor jack. There are 6 hexes so you can get the bar in 60 degrees 'out' and have the LCA almost stick straight out, this position will not support the front end and it will lower all the way to the stops. You should not have to loosen the adjusters.
