Remove the wheel, tape up or remove the innerfender-well flap, use a 5/8 spark plug socket, slide it up onto the plug and use a 3/4 wrench on the end of the socket ( I used a ratcheting wrench, they fit in the space nicely). Remove the plug, lube the rubber inside the plug socket for easy removal. The easiest way to install the plug is to put a piece of tubing on the end, lube the threads of the plug and use the tube to spin the plug in. Then use the socket and wrench to tighten. It took me 2 hours today to change mine and this is how I was able to get it done.
easiest way is jack up the truck place a jackstand under the frame remove left front tire and inner splash shield if needed and remove the spark plug through fender well

What I had to do is to take the plug socket and put it on the plug then take a open end wrench (3/4" I think) and break it loose. I then took a piece of brake tubing and put it over the end of the plug and backed it out that way. To install reverse the procedure. Otherwise you will have to take the steering column loose.
easiest way is to remove the tires and go in through access panel, real quick and easy
