Driveshafts for 231 to 241OR transfer case swap?

Today I replaced the NP231 with a NP241OR in my 2006 65th Anniversary Edition. Jeep has a Dana 30 in front and a Dana 44 in rear. I have a 3" lift.

Now I have to decide what to do with drive shafts. I could get the Tom Woods Rubi shafts for around $650 with optimized lengths and correct ujoints, however, I got the stock Rubi drive shafts with the xfer case to avoid that cost. I would expect them to work since I don't think folks replace their drive shafts on Rubi's with a 3" lift (not sure about that).

The rear stock rubi shaft bolts right up (correct ujoint at diff), but there is about 3 more inches of the spline end of the slip showing (black in pic). Spline itself is not showing.




Looks like the front would work too if I get a 1330 flange for the Dana 30 up front? Does that sound right up front?

I'm a little concerned with the length on both shafts. Has anyone done this swap and been successful using the stock rubi shafts.

Thanks!

The front Rubicon DS will not work bc it is will be too short. You can use your stock front driveshaft though. You can get a 1310 output for the transfer case. I just went through this on my LJ not too long ago. Your 44 should have a 1310 pinion yoke like my LJ did but you can just get the 1330 pinion yoke or get a 1310/1330 conversion joint.

Perfect! That is exactly what I needed. I will get a 1310 output for xfer case and use my stock front.

Thanks! Great timing too...I was just about to head out and get a 1330 for the front diff so I could try and use the rubi shaft.

You provided a much better solution!

Really appreciate it!

I dont know if I would trust that rear, looks like it could separate pretty easily

I agree....don't think it is a good route. Now that softballnrd27 gave me the solution for the front, I think I will just spring for the Tom Woods for the rear.

Thanks!

I'm headed out to find one now.
Thanks though!

That sounds really good actually. I can wait. Really appreciate it!!

Some more info....

So over the weekend I cycled the rear suspension and the Rubi rear shaft does not show the spline at full droop. I figured the Rubi shaft would work on the rear since I have a Dana 44 so it should be the same configuration as the Rubi. Looks bad in the picture because the shaft was sitting out in the weather without a boot, fully compressed...the black part is the paint which was not exposed. Soooo I'm going to use the rear Rubi shaft and my stock front shaft.

The Ujoints are shot so I ordered a Spicer 793x and a 795x based on a post I read regarding the ujoints for a #410AD shaft. Turns out the 795X on the xfer case side is correct, but the 793x on the pinion end is not correct. I pulled the shaft and made measurements (which I should have done in the first place). Need a combination ujoint on the pinion end of the #410AD, at least on this one. Looks like a 1310 to a 3R. A Spicer 5-3022-1X appears to be the correct ujoint. Or at least that's what I measured.
