Default Info on gears & axles?

I purchased a 2011 Sahara JKU automatic w/ 32k miles (no mods that I can tell). How do I know which gears I have and what axles?

Email Chrysler customer care and ask for a build sheet, just leave your vin. Otherwise Jack the rear up and count rotation of tire vs drive shaft. If your wheels spin same direction then you have LSD.....

Also you can go to jeep.com under the Owners section and create an account. Register your vehicle with its VIN and it will give you a build sheet online.

I just called the service department at the dealership and dictated my VIN to the tech over the phone... 2min later I knew my gear ratio.
