Ryan you have misread what I probably haven't written too well---If this site would ever get where I could post pictures as I want, I could better illustrate the points that I think are failure bound------Its not the stud, tapered or not-its the threaded part of the tube at the very end of the tie rod end-in this case-6 to 8 inches from the end-

And I've worked on lots of ag and industrial equipment over the years and seen lots of thse shaker things-------the torque and force used there is no where near what you'll see on a v8 driven vehicle transmitting 400 hp or hundreds of lbs of thrust (engine multiplied by gear ratio) into the rods that connect the rear end to the frame-add in chough holes, bumps, slamming speed shift gear changes, full throttle downshifts---------
