name of this part?

There is a "two hammer" method, apparently well-known to mechanics. Search for an article on Mustangs. I haven't tried it yet. I use a pickle fork on tie tod ends since I always replace the boot anyway. Sometimes I jam the fork in, then use a Pittman puller, putting the jaws over the fork. Of course, WD-40 soaked over-night helps. On my recent 65 Dart suspension/steering rebuild, I put anti-seize on the lower half of the studs. I hope that doesn't cause the stud to spin, but "too tight" is usually the problem when you try to remove them.
