I'll probably get beat for this but I can't resist. Here is a page on identifying axels.

If you want to identify an axle you can do what SlikRic said. Sorry, I could not help myself. I'll go away now.

So true, axle has to be the most misspelled word on the 4x4 internet. Triple axels are pretty hard to do though.

AMC 20. I believe it depended on what engine you got.

I actually pulled the covers today. Front is a Dana 30. It has a 272 gear ratio. 49 teeth on the ring gear and 19 on the pinion. The back axle is a amc 20 with a 273 gear ratio.41 teeth on ring gear and 15 on the pinion. Is this normal for them to be different?

You should count your D30 teeth again because 49/19=2.578. An unheard of ratio in the world of Jeeps. Pinion should be 18 teeth.
