Special tools are required to adjust or remove the track rod end. Sooner or later, the hammer and screwdriver method will destroy the internal thread of the track rod end and the screw. I made something out of a 1/2' nut. I've bent the nut so that only the holder for the ratchet remains. Then I welded a cross of 3 mm thick metal strips, which fits exactly in the adjusting screw of the rail end. Now you can unscrew the screw or make the adjustment with feeling.
