2004 Rubicon rear axle
 
SO I may be going to look at a Rubicon dana 44 rear axle geared to 4.10. It does not have the stock locker, but an ARB. Between a standard Dana 44 and a Rubicon Dana 44. Isn't the only difference the locker/carrier?

Carrier is different as you mentioned but only to support the thick cut gears used stock and aftermarket.


What are you wanting to know about it other than that?

Dana 44 (216mm) - 1997-2006 .....

* Optional rear axle used on 6 cyl models except the Rubicon model
* Stock gear ratio options - 3.55 (97 only), 3.73
* Carrier Break = 3.73 / 3.92
* Standard Trac-Lok limited slip differential on early model TJs / Optional on later model TJs
* Ring gear diameter = 8.5"
* Ring gear bolts = (10) 3/8 x 24 RH - Note: 7/16" x 20 RH used on later model TJs
* Low pinion
* Pinion shaft diameter = 1.376"
* Pinion shaft spline count = 26
* Axle shaft diameter = 1.31"
* Axle shaft spline count = 30
* WMS-WMS = approximately 60.5"
* 5 on 4.5" bolt pattern
* Available for the 1997 and newer 4.0L TJs only after 7/7/96
* Threaded 3/8" fill plug

* Ring gear bolts = (10) 7/16" x 20
* Low pinion
* Pinion shaft diameter = 1.376"
* Pinion shaft spline count = 26
* Axle shaft diameter = 1.31"

That is exactly what I am looking for. It is out of a 2004 Rubicon. Will my stock TJ drive shaft match up or will I need an new one?

What is the difference between the stock Dana 30 axle and the Dana 44 in front?

your shaft may be to short...the Rubicon uses a flange to bolt to the t-case not a yolk as the standard np231 t-case. And the ujoint is different size. You will need a conversion u-joint at the rear of the d-shaft if you use your current shaft.

Ring & pinion are different as well, you'll notice on most of the gear sites that have options for Rubicon D44.

Thanks distortedtj. That is exactly what I needed to know. I now need to go take it off his hands.

Yeah seriously, who would want a bigger ring gear, deeper ratio, thicker axle shafts, and a locker stock from the factory? At least you get a sticker to go with it...
