at the beginning of this past summer I replaced both tie rods, the center steering link and the steering damper myself, it was only a few days after I finished that project when I had the car aligned. Assuming the job would take the dealer about 5 hours and the parts cost near 100 the total cost would be about $600, how hard would it be to replace the balljoints myself and what special tools are needed for the removal and replacement of the balljoints?
