A trusted mechanic who is comfortable and confident with their gear work would be my first suggestion. Don't get anyone to do it who isn't comfortable with doing it- no "one stop" shops if you'd like your gears to last and serve you well.
*IF*, and only if, you have a really good dealer then that's an option. Again- make sure you talk to the guy who is going to do it. Anyone can install gears but setting the tolerances where they belong is the important part.

Great info and advice. Mine were done by a guy who was a Jeep dealer service tech for 17 years. He now works on Jeeps as a passion/hobby/business. They cost me $1100 including the gears. They MUST be done by someone who can set the tolerances!

I currently live in Bethesda Maryland. But I may be moving to Charleston South Carolina in a few weeks. It sounds like I should do some research and find some local mechanics

From some who's had 35s for 2 years and 37s for 18 months with 3.73 auto with the 3.8.....not worth regearing IMO. I'm 95% on roads, no highway, rare offroading (not my choice). Flashpaq was all I needed...

I have a 'new to me' 07 Unlimited Rubicon. I was wondering if I could reuse the factory Rubicon lockers if I regear. I'm sure that aftermarket lockers are generally better. I think for my application (35"s with 90% highway and a couple of trips to Moab and local trails) they should be sufficient.

Verify that he is comfortable with rubicon axles. There are quite a few posts from people saying "just regeared, and now my lockers don't work!!!" or " Won't disengage!!" It has something to do with the position of the plunger, and would be worth a few minutes of your time to research it.

Old tire size/new tire size*existing gear ratio=effective gear ratio
31.5/34.5*3.73=3.4:1 Would feels like ... meh.
New tire size/old tire size*existing gear ratio=equivalent gear ratio
34.5/31.5*3.73=4.08:1 Would feel like it did with the original tires ... kinda.

But wait, there's more!
New ratio/existing ratio*old tire size=projected equivalent tire size
4.56/3.73*31.5=38.5
Of course you can't really go on that completely. There are other factors. Increased mass, wind drag, friction to name a few.
