I apologize in advance if this is a total noob question; I also tried searching prior to posting.
The below is a clip of my window sticker. I just put on a lift and 35s, and would like to gain back the MPGs I lost. My question is what do I need to get in order to re-gear to 4.10 gears? Do I do need to only change the rear diff gears, or do I have to do both front and rear? I would assume both the front and rear gearing needs to be the same to drive in 4WD, but I might be very wrong. According to the sticker, I have a Dana 44 rear axle, and I have a 3.45 axle gear ratio. Very lost and any help is much appreciated.

Both differentials require the same ratio.

I would recommend using 4.56 gears with your 35's.
