It's either the 3.73 or 3.21. I'm just having trouble finding out which one it came with. I'm looking through receipts and owners manual and such. Do you know where I can find this? I know the tire and wheel info is on the inside of the driver door so I'm hoping there is something similar somewhere on the Jeep but for axles

You can get your build sheet here. Enter your VIN at the end of the URL, after the vin=ABC123

Do you know if you have the max tow pkg on your jeep? If so then you'll have the 3.73, if not then you'll have 3.21s. If you have your original invoice sticker (window sticker) you should be able to confirm it. If you dont have it I think you can call Jeep with your vin and they should be able to tell you or send you a build sheet. Good luck.
