This is going to sound lame, but are you getting ANY movement out of the adjusters?> If your adjusting the hex head screw, thats for removing the light. But if you are adjusting the torx head screws, and they arent moving, then something is stripped or something... Im having headlight trouble with mine as well, but its getting the assy out that I cant do.
you sound like it should be just fine with the truck lowered and not raked etc...man, i dunno. sorry I couldnt help more.
