It depends on if you are used to playing with tinker toys or space shuttles... and what model year. If you are savvy to do-it-yourself mechanics, it should take about an hour and a half per side. If you have never done it before, I STRONGLY suggest the aid of a good manual with lots of pictures and instruction verbage.
it depends on your skill and the facilities you have to work with. if you came to my shop we would charge 3.2 hours to replace it.
6.6 hours including the a/c recharge plus parts....................
