Well I am having the same problem on the drivers side as I did on the passengers, only worse. The tapered ball joint shaft will not come out of the lower control arm. I even broke the giant autozone type c clamp joint puller - cracked right through. I have pounded on the shaft with a sledge hammer for hours, carving 1/4" deep impression in my concrete garage floor with the jack stand supporting the lower control arm while I beat on it. I was thinking about packing the joint/arm in Dry Ice to try and shrink the joint enough to free it up - Do you think the dry ice would weaken the control arm and cause issues later on down the road?
