Which diff?
 
Which diff should I get on my 2008? 3.21 or 3.73? What is the difference in gas mileage?

if you ever decide to go larger on tires you will be glad you got the 3.73. And if you go big enough, even that wont be enough gear...

That depends on what you going to do with your Jeep.

If you plan to use it as "Mall Crawler" then get 3.21, you'll get better MPG.

If you plan on modding it and taking it off-road then go with 4.10 it will eat a bit more gas, but when you are climbing a hill or stuck, you will be glad that you got 4.10
