My 1997 TJ service manual says the stock front axle is an 181 FBI.
Is that what the rest of the universe calls a Dana 30?

OK, great.
Now one more question:
To change the ring and pinion from 3.07 to 3.73, do I need a different case (aka carrier)?
I belive so. AFAIK, D30 and D35 carriers go from 2.73ish to 3.54 and 3.55 to
5.13HTH,

yes you need a new carrier
Thanks for that listing.
I don't see 3.73 on the Dana 35 listed anywhere there?
Does mean I can just change my ring gear to change my 3.55s to 3.73s?
DANA 35 7.56" AXLE RATIO and tooth count: gear ratio ring gear-to-pinion teeth
3.07 43-14 3.31 43-13 ***********(carrier change here)*********** 3.55 39-11 3.73 41-11 4.11 37-9 4.56 41-9
The rear is definitely a Dana 35 unit. not a 44. I replaced a collision- damaged Dana 35 3.07 with a donor Dana 35 that I was told is 3.73. It's something different because the speedometer is way off now.
Here's the donor I bought and installed:

3.73 WAS availible in the dana 35.

Which means it was also available in the D30 ...
If I recall correctly, the 3.73 gears came with the automatic transmission.
AFAIK, 3.55 was standard with auto, 3.07 was standard with manual, 3.73 was towing package, 4.10 was 4cyl.
