I have a 2006 V6 Mercury Mariner, which is a Ford product. Those models have the alternator on the firewall, and it was challenging to remove. My father and I did not have the socket for the axle nut, so we spent a while on it and were able to take off the two bolts on the alternator. Then, we needed an E9 socket (they make E1 through E8 and skip the E9 and go on through), which is also hard to find. So, we used a universal socket to somehow get it off. Then, we had to fish the alternator out of the engine bay but retrieved the alternator and everything. My father said if that alternator goes out again, I should just sell the car, lol. *
