I'm in the same boat as you and about to pull the trigger myself. For the front I would choose a selectable locker. Your Jeep is a DD, if I'm not mistaken, and a selectable will be a lot easier to drive. You could go with an Automatic locker in the rear for a little more street-ability. You can re-gear and lock the D30, no need to worry about that.

 

Here we go more miss info, your locker is not even play unless the Jeep is in 4WD.

 

Thanks Rhino, they put a Lockright in frt, not an Aussie. I'll tell them about it. I originally asked for an Aussie, they said they used Lockright.

 

I had a Lock-Right in the rear of my TJ which I drove for near 80K never had any problems with it. You could hear a little clicking when turning but that was about it. I know people do use them for front lockers and seem to be happy with them. I'm not sure if they make one yet for the new D30 or if they are just putting them in because they seem to fit like some have one with the Aussie. There is differences between the Aussie and Lock-Right but they are very similar, The lunch box locker is not a perfect solution however it is a inexpensive fix that does work pretty well for the most part.

 

Lots of debate goin on up above...

You've got a 3.73 ratio. 4.56 with your 6-speed and tire selection sounds pretty alright to me You'll be happy.
As for the debate front or rear, selectable or auto....
What kinda wheeling do you do? Is this a daily driver? The answer to those questions can help alot.
You can always re-gear first and tackle locker install later...particularly with an aussie in the front, you can do that yourself....you could even install a selectable or other complete unit yourself as well, just takes a couple extra tools, some shims and new ring gear bolts, it CAN be done...ask dpoelstra
Some food for thought

 

Hey Rhino, do you think that the Aussie is going to cause the same type of backlash to my TC? You can turn the driveshaft 1/4 turn with the jk sitting still.

 

To answer your questions...

Currently I have 3.21's

Yes it is a Daily driver...

As for wheeling....Rocks, not huge (blues and easy blacks)...some water and mud and sand.

I am thinking I should get the locker done now with the gears to save money. I would not trust myself putting a locker in...

 

But your profile says your an '08 That means you have 3.73's...they dropped the 3.21's from the '08 line in favour of 3.73's for X and Sahara, tow package or not.....unless something weird happened with yours, stranger things have happened.
I think more people need to have a little faith in their mechanical abilties...you'd be surprised what you can accomplish on your own. Though I understand people are very busy, and not everyone likes skinned knuckles and such....but the Aussie can be installed by the do it yourselfer...heck so can locker installations and gears, just takes a few more tools and some knowledge.
Anyways...I have no personal experience with auto lockers at all, front or rear...I do agree with you, they sound GREAT...Rhino seems to have some knowledge and experience here...and there a tons of people with them installed on this forum and most people swear by 'em.
The great thing is...you really could have your gears done now, and save yourself some cash and have an aussie installed later in the front by yourself...or a friend perhaps??
The other thing to consider, do you have snow in your area?

Here we go more people that don't have to drive in the snow on the streets in 4hi telling you to put an auto locker in the front.

 

Maybe a 1/4" movement differently not a quarter turn. There is something wrong for sure, I don't know what but I don't think its the lock-right that causing it. When you find out please let us know.
