How the H E double hockey sticks do you remove the drivers side front/1st A-F/O2 sensor?

I've been at it for the last hour and I can not get a wrench in there and move it.

First do you have the O2 sockets and crowsfoot.
I found the crowsfoot worked the best.
Next I went through the wheel well to get it loose, also if you warm it up it makes it easier to loosen then after it cools down you can then remove it.
DONT FORGET TO THREAD CHASE THE PIPE BEFORE YOU INSTALL THE NEW ONE WITH ANTI-SIEZE ON THE THREADS. !!!!!!!!!!!!!!!!!!!!!!!!!
I have to do the exta same one again and am not even sweating it.

Go in from the side, not from underneath. Remove your wheel, pull the rubber liner, and you should be able to see the o2. Still a pain but much easier.

I got it out... I ended up dropping the skid pan, drive shaft and the trans/cat bracket to get enough room. I also snipped the cables and with a super deep socket and a long breaker bar. Once I got it loose, I was able to use an open ended wrench.

I couldn't figure out the wheel well, it points into the center of the truck.
