Glad that worked. I have a big, fast impact wrench, and all it did on mine was spin the nut, stud, and ball on the other end (i.e., counterholding the shaft was a must). I guess, you lucked out and the nut was not fully "frozen". If the impact would not have worked, your mechanic bill would have been $$+$$$=$$$$$, as then it gets to be time to be "creative".
