I'm working to change out the plugs myself on a 2008 Commander, 4.7-V8. Having a hell of a time getting to the plug with my 5/8s socket. Has anyone had this problem before and what is recommended. I got the socket in there yesterday when the engine was a little warm, but today, I can't get the socket in there at all. I've also tried using a neighbors socket wrench, and once again I can't get in there to access the plug.
