Flipping heck, no way have you got a mrs or kids progressing at this rate LOL
With drop links, the nuts seize cos the threads jam up with crap above the nut, it sends the nut tight and spins the balljoint instead of the nut. It's common on all the balljoints from old to new. When I remove a balljoint like that (Track rod end, drop link etc) I wazz a little WD40 on the exposed thread and then blast around it with a wire brush fitting on a drill. This cleans the threads up, and then I lever the joint from the back (if possible) pushing it in to the fitting and hit the nut with an air gun or rattle gun. It spins the nut off 99 times out of 100. If the joint doesnt knock apart easily with the nut off (track rod ends stick sometimes) don't risk damaging the thread, just heat the arm, as it expands the TRE will just fall out.
