When I did it, I put a "box" wrench on the nut,small one at the top left, and hammered the end of the box wrench "up", in your case, until the nut loosened. I also think a warm engine helps, as was mentioned earlier. Then I unscrewed the the solenoid "Lefty" for a "lot" of turns. Can't give any more help than that!!! Perserverance, on your part, or take it into the dealer $$$$. I wish I was in on this earlier, before you all went chisel!!!! It is frustrating :cries: but high fives on the outcome are well deserved as your steering will radically improve. These cars have a lot of well thought out Engineering and circumventing that lock nut is not a good idea. It must be loosened "first". God Speed.
