I second the hammer method.

Although it may sound crude, two or three hammer blows along the side of the center-link where the tapered stud is fitted is usually all it takes. Resist the temptation to hit the threaded portion of the old tie-rod end and leave the nut on partially (two or three turns). Heat is another alternative but hitting something that splatters hot grease is not really necessary. Try the hammer method but be sure to give yourself ample room to make a few solid strikes.
Good luck.
