Use the BFH on the knuckle, on the side, never on the stud. Use a big hammer with a steel head that you can swing handily. A small hand sledge or a big ball peen. If possible put a pickle fork in, or use some kind of leverage to put the tie rod under some tension. It doesn't have to be much, and it's optional. Leave the nut on loosely so it doesn't fall out when it releases, and then hit the outside edge of the knuckle good and hard until the stud pops out.
