Wheel Bearing Adusting Nut Size

it's like 12in lbs, or 1lb on a 12in lever, which is almost nothing. I tighten it with some channelocks a little tight to align the rollers in the bearings, then back off slightly, while turning the drum/disk and also stopping to check the wobble by trying to rock the drum/disk by pushing & pulling while grasping the top and bottom of drum/disk. I try to just tighten it back up until i eliminate the wobble when I put on the castelated lock nut to line up with the cotter pin hole in the spindle. I hope that makes sense.
