Did not think you were questioning me at all, I just found that it was humorous that my techinque was so similar to the file you mentioned.

As far as the nuts go it could be a case of they did the review on a first year model car and never redid it. On the first year model cars the ball joints are fastened to the control arm with studs and nuts so that if you removed the nuts you could drop the arm out of the way much the same way as pulling the ball joint down out of the knuckle.

Remember when you are using the hammer technique to pop a tie rod end or ball joint of the same design(not the 850 design) that you want to hit the outside of the piece that it goes through and not the threaded shaft in any way.
