Do you have the 3:21 gearing right now? I've read before if you do you'll need a new carrier. If you have the 3:73 up you won't.

That is correct if you have 3.21 gears in the front D30 axle you will need a carrier. If you have 3.73 gears in the D30 you will be OK. PM us for pricing on gears and master install kits.

Just the front with 3.21's. The rear carrier is fine. (this is a JK 44 that uses the JK 'thick' gears. You may be correct on the carrier break for non-jk d44's..)

You do not need to replace the rear carrier with 3.21 or with 3.73. If you have 3.73 you do not need a carrier in the front. If you have 3.21 you need to change the front carrier.

Jeep.com website. Find the Contact Us area, email them your VIN and ask for a build sheet. That will tell you what it left the factory with. If you think a previous owner might have regeared, lift a rear corner, mark the tire and the driveshaft, spin the tire and count driveshaft revolutions. Or, open up the diff and count the teeth.
