Does it get too tight to tighten, or does the nut spin without moving? Details, (or pictures) please.

If it gets too tight to tighten, it's on too tight, or possibly just out of alignment

If the nut or bolt spins without tightening, you might need a new nut.

explain what you mean, i dont get whats going on with your nut on the kingpin frankly

sounds like cross-threading.
Have a look at the grooves on the inside of the nut, they may have been damaged.
