Torsion bar removal
For breaking the lower ball joint (or tie rod ends, etc) loose I use two large hammers. Loosen the nut four or five turns. Place one hammer against the side of the part the ball joint stud goes in, give the other side a very good rap with the other hammer. This distorts the metal, popping the stud out. There is no damage to the parts, as the stud won't let the hammers deform the metal enough to hurt the part.
