The manual says to measure the hight of your bulb from the floor. Transfer that hight and draw a line on paper on the wall that is 25 feet from your headlight. Draw a center line as best you can by eyeballing the center of your truck. Measure the distance your bulbs are apart and transfer that to the paper. The low beam's center should be 2 inches below the horiontal line. Side to side should be ok as all you did was raise the front end. That should give you somewhere to start. Adjust as necessary.
