Thanks for the replies so far.
I was thinking about the OX Locker, then about upgraded axles. I figured I should replace any components that had some wear since I will be adding new parts. Then it started coming down to my ability to get it done and the time it takes for a beginner DIY.
I also read about the 8.8. I am looking at various options and opinions. That is what is so cool about this forum.
For the time being I will stick with the 33s. I do have a D44 in the rear. But I want the new one! (whining and pouting). But really it goes back to upgrading the axles, installing the lockers, etc. I figured i could get back some of the money I spent by selling the front and rear axles.
By the way here is the link to the G2 axles and specs:
Axle Assembly - Front Axle Assembly - Dana 44 Axle Assembly
I got the pricing from an ad in some Jeep porn mag.
