Just out of curiosity, I have a few regear questions. I'm new to Jeeps, so please bare with me....
1) When you re-gear, do you need to do both the front AND rear diffs, or just rear only?
2) Most of the time, is it a core exchange thing? Like you buy a D44 with 4.88s in it, then ship back your OEM D44 for a core exchange? If so, anyone you know online that does this?
1- yeas you have to regear both front and rear axles, if you do not you will cause major damage to your drive line, because the wheels front and rear will not be turning at the same speeds.
2 core exchange, yes you can remove the axles ,,,, but thats a major job, its best and cheaper to have a shop do it while the axles are still in the jeep. prices range anywhere from 1500 to 3k for a regear
3- yes 2012 can be regeared, although you will need a pro-cal or other tuner to let the ecu know what you have done, this will fix your tranny shift points and your spedo will work correctly.

I believe you can regear just the rear so long as you don't engage 4wd, no? Certainly if you disconnect the front driveshaft. Might let you split the install costs over two appointments.

I actually think that due to the Wrangler's excellent residual value, it might make sense later on to trade in for a 4.10 Rubicon. The money I lose will be almost the same. If you factor in wear and tear, I might actually come out on top.
Not sure what your specific situation is, but I think the decision whether to get a Sport or Rubi often comes down to whether the 4.10's are going to be sufficient for whatever tire size you intend to run. If not, you are regearing either way so may as well get the Sport and possibly install lockers when you regear.
Me, I think the stock Rubi package is sweet, 2 door '12 with a stick and 4.10's is perfect for me.
JT's Parts and Accessories can also build complete axles, using Mopar D44 housing and ship them as a bolt-on unit. Not cheap, but makes for an easy swap.
So one is looking for about 4.5K for both. I wonder what the value of the entire OEM axle set is. The problem with re-gearing (and I've experienced this when re-gearing my sports cars) is that it is SUCH a sensitive and specialized job, that most shops are simply not qualified to do them.
