About as much as an Atlas...
OP, IMO go get your gears swap done. This will help out your driving off road, and on, and then when the time comes you can upgrade the tcase and you'll be that much better of a driver. Just my opinion.
You can take what toymaster said a step further.
your setup now (3.73*2.73*4.46= 45.41) with a final crawl ratio of 45.41:1
So say your trying to get over something just idling along at 1000 RPMs
1000/45.41= 22 tire RPM/ 60 = .36 tire rotations per second.
You have 34" tires so
Your speed now at 1000 rpms is about 3.2 feet per second. If you followed that then
Now with your new gears at 4.88
1000/59.41= 16.8 tire RPM/60 = .28 tire rotations per second
Your new speed at 1000 rpms would be about 2.5 fps. It doesn't look like much on paper, but its a significant differance when you actually jump back in your ride.
No doubt, in the math the place to get the super low crawl ratio is in the Tcase, but for starting out, you'll be happy, and impressed with the drivability of a new gearset in your axles. And like Olean said, they're cheaper than a new tcase.
