Transfer case ?

Just a quick question. I'm guessing it is a Dana 44 but want skilled eyes to look. And what do all the numbers mean. And is the 44 good?

That's a differential, not a transfer case. Yes, it's a Dana 44. It's the strongest rear axle Jeep put in the TJ. I believe the numbers on the tag indicate the gear ratio. The numbers on the housing should tell you it's a Dana 44 and if it originally came equipped with a limited slip differential.

That is a D44! Congrats.

But the transfer case is in the center of the Jeep behind the tranny. Yours should be a NP231.

sweet.. and I only have an '04 sport which I hear they normaly come with the 35. This makes me happy. And as far as I can tell it never really went off road. I took it to the black hills in South Dakota last year and hoping to do some more wheeling in the near future.

When it comes to gears, how can you tell what gear ratio you have and what does it really do?

If it's all stock and a D44, chances are it has 3.73 gears. If it is an auto and a '04, you have the 42rle tranny with OD and you will definitely have 3.73 gears in it.

Lower gears are essential when going to larger than stock tires. They keep the Jeep from losing the power on the road, and improves off road low range.

That little metal tag to the left should have your gear ratio stamped into it, if you can chisle some of the dirt/grime off of it.

The numbers associated with a front or rear axle gear ratio(s) refer to the numerical relationship between the ring gear & the pinion gear. It's basically the number of revolutions of the pinion gear that it takes to spin the ring gear one complete revolution. Lower gears (like 4.56 or 4.88, etc) are preferred for rock climbing or steep trails (off road activities) and general street performance. Higher gears (like the 3.07 gears that a lot of TJ's came with) are supposed to be better for highway driving and gas milage. If you don't have the factory tag on your axle, you can use the method in this link How to Calculate Gear Ratios by Rotating a Rear Wheel | eHow.com be sure to read all steps and the tips and warnings.

I'm not referring to the numbers on the tag. The method that I suggested is for when you don't have a tag or you can't read it. Then you follow the instructions in the link.
