update>> it was packed in dirt - i finally got enough loosened up - that i was able to get the socket on the plug : )
--
i replaced 3 with no problems - other than they were tight as hell - well after 100k miles - i guess they thought they were never coming out again. but this last one - socket just spun and spun. what am i looking at - just got this pic - as i could not see in the hole during the daytime.
