The stud on the outside end of one of my tie rods spins with the nut, which makes it difficult to remove the tie rod.

Suggestions, before I start in with the hacksaw?

Na, just go for the hacksaw... and report back to us when you are finished.

Yea, better to break that bolt with a highspeed impact, with a jack underneath.

I've had it where I broke the bolt, but not not far enough to spin freely, then broke loose the taper press. Had a bugger of a time getting the nut off after that.
Had to place a jack underneath and wedge in a tapered fork.

You mean on the ball joint part? You could try a vise grip on the stud to hold it solid, but you'd probably do more damage than just cutting the nut would.

Use a floor jack under the tie rod to press it more tightly up into the taper. Friction between the stud and the taper will keep it from turning long enough to work the nut off.

Jack to lock the taper, impact to remove the nut.
No need to cut
