After hours of struggling to remove the rusted-in cotter key from the top of the tie rod end, I finally was able to grab it with vise grips and eventually knock it out with a hammer. Now with the nut removed, I can't get the tie rod end to budge. I put the nut back on it partially and beat on it with a hammer, soaked it in Liquid Wrench, beat on it some more, but it won't budge.

I'm looking for suggestions here. Anyone?
