I've basically rebuilt my entire drivetrain but ran into an issue on the finishing touches. I'm trying to tighten the nut on the bottom of my outer tie rod end, but the bolt keeps spinning. I was told that means they're bad so I bought two new outer ends. Wouldn't you know it I'm having the same damn problem. Would a C clamp help me or does anyone know any secrets? Any information would be helpful, I'm tired of this thing just sitting in my garage. Please help! Thanks.

 

if your still working on this...
use a pry bar to push the tie rod on/into the ball stud the force should hold the worn stud and allow you to remove the nut.. the a good whack with the hammer on the spindle should pop the stud out.. unless all the spinning has already got it lose...

 

This does happen frequently, you need tp put some pressure on it first to keep it from turning so you can tighten the nut. Some use impact wrench to tighten it, I would try to pry or use the C-clamp like you suggested.

First make sure that there's not a hex recess in the bottom of the threaded portion so one can hold it steady with an allen wrench while tightening with a box wrench. I guess one could also remove the tie rod end (again) and hacksaw a small groove in it so you could do similar with a screwdriver to hold it tight. That grove would end up being beyond where the nut rides, so you wouldn't be weakening the threaded portion where it's attached.
