Can someone help me out adjusting the headlamps on my 03 RAM 2500 4X4 QC. I've put 315's on the truck and would like to lower my headlamp beams. I find one "torques" adjusting screw beneath each headlamp. I spotted the headlight beam on my garage door and turned these screws several times in each direction. Doesn't seem to change the headlight aim. Where do I go from here?
