search gears or re-gearing. This topic has been debated at length on this forum. You can can some performance improvement with a CAI, exhaust and chip but the gains are minimal with a Jeep. The best way to improve performance of larger tires is re-gearing. There are a couple of quality gear manufactures out there: Superior comes to mind but there are a couple others who's names are escaping me right now. If you regear, be prepared to spend $1,000 to $1,500 for gears and labor to install them. Don't try to install gears yourself unless you know what you are doing.

I'm sorry, it's a writeup in progress. It can be done by the do-it-yourselfer providing you have the patience, can obtain the right tools and study the process until you have no questions. When you can understand what bearing preload is, and how backlash and pinion depth are adjusted and what all those terms mean and how they effect each other, than I firmly believe you can do it yourself.
The gears in our diffs are where all the rotational energy from the engine is transferred 90 degrees to our axles...no doubt it is a daunting task.

How's your tool box? There is a fair amount specialty tools you'll need such as:

2. press
3. mic or calipers
4. dial indicator with magnetic base
5. 35mm socket
6. in-lb torque wrench
7. ft-lb torque wrench
8. pry bars
9. case spreader - optional
10. seal puller - optional, if not replacing bearings
11. puller - to remove flange
12. puller - to remove carrier bearings
13. brass punch - optional, if not replacing bearings, used to drive races
14. 400 ft lb impact wrench
or
15. pinion flange wrench, rear, with loooonnnggg arm
16. seal driver set - optional, if not replacing bearings
17. dead blow hammer
18. tube to fit over pinion and press inner bearing onto pinion
18. EXPERIENCE, friends with experience (and time) or tons and tons of research.
