What axles do I have?

Sorry but this this could be confusing information. The carrier breaks are correct but not for a JK (or TJ Rubicon) application.
You'll need a new carrier for your front 30, but you'll be fine with the rear carrier.
All JK 44s use a 3.73 down carrier. The 4.10 and up gears are all what is known as 'thick' gears and don't require a different carrier (3.92 is an odd gear set and not relevant). Regardless of whether they are 3.21, 4.10 or 5.38, they will all fit on your rear 44 carrier.
