So, if you're looking for a Haynes, Chilton's, or similar, that is not what most people would call a "Service Manual". There is a difference, and a reason that you might want a factory manual some day. Eventually, all of the Haynes and Chilton manuals can be boiled down to "figure out what is wrong", then "remove all parts attached to the broken part", followed by "installation is reverse of removal". That is great for a lot of people, but eventually you figure out how to fly solo without that aid. They are certainly worth the $19.95 or whatever they run now, and are great sources for stuff like torque specs, but YouTube can also do most of that for you.
I do like the Haynes "Techbook" series, as they are a little more detailed, but specific to topic and not vehicle.
A factory "Service Manual" usually includes things like wrench and bolt sizes, troubleshooting fault trees, wiring diagrams, optional engines, axles, drivetrains, and specialty tool requirements in addition to transmission and axle specifications, etc...
A Haynes or Chilton generally says something like "rebuilding this part is beyond the scope of most mechanics"... "curl up in a ball and cry until you can afford a new truck"...
Seriously though, there is a huge difference between what I initially thought you were asking for and what I now believe you want. the factory service manual is worth $200+, and if you can download it onto a $50 Craigslist tablet, so much the better.
Either way, I don't have one, but appreciate you asking the question, because I'm finally free of the FCA warranty morons on my JK, and would like to find one.
