Got the Mopar 2009 Performance Catalog today. Went right for the Jeep section and on page 277 found this:
P5155256 Axle, Front Assembly, Dana 44, JK, Modified For TJ
P5155257 Axle, Rear Assembly, Dana 44, JK, Modified For TJ
That's right, those are JK Rubicon Dana 44's, 4:10 gears and a locker modified to bolt in to a Jeep TJ.
So that's the good news, the bad news; sit down when you call the dealer for the pricing
