If you're referring to the tapered stud, use a large channel lock pliers to squeeze the socket to the steering arm. That will put pressure on the ball and socket to stop the ball / stud from spinning. It shouldn't take more pressure than you can squeeze with one hand. If that doesn't work, either there's excessive wear in the joint and it must be replaced, or the threads are damaged or rusty. For that, use a die from a tap and die set to clean up the threads.
Some tapered studs have a small hex at the end of the stud to hold it with a wrench while you tighten the nut with another wrench. That's the painfully slow way to do it. If there's no hex, you can hold the top of the stud with a vice-grip pliers.
Let me know if either of those methods works for you.
