Did you lift the front of the truck with a jack because it make easier to turn the bolt.It that the only reason???
im no expert but from what ive heard its the proper way to do it.. you jack it up to release the tension on your suspension, so you can properly adjust it. im sure someone has a better explanation for you
so if you do this and you crank both bolts the same amount of turns, say 3... and when you measure it the pass side is higher should you adjust the drivers side so that they measure the same and one bolt has more turns or do you leave it the same number of turns???
