Easily done. The driveshafts will be different, due to a slip and fixed yoke, along with 1310 and 1330 axle ends. Also, the 44 is slightly longer at the pinion.
I have 40k jeep he has 130k or so... mine has been in the family its whole life, I'm too attached lol his is wrecked, minor front end damage plus mine has lived in a barn or garage in a dry climate its whole life, aint no telling where his is from
If you also swap the tcase, swap the drive lines as well and you don’t have to worry about making any mods to them as everything will be the correct length on both jeeps. Just did this exact swap a few months ago. The only issue we ran into was the rubicon was an auto and the sport a manual. We had to put a new input shaft in one of the tcases (I think it was the 231) as the auto and manual had different length input shafts.
what about any sensors or check engine lights on the rubicon. I don't want him to have any problems after the swap. I mean I'm getting a driveline with 100k more miles on it than mine. Makes me want to just do the Super35 kit and keep my driveline.
130K on those axles is nothing. As far as the sensors, there would be no issues on his end. That said, given the low miles you have on the Jeep, I'd be inclined to keep what you have. The 44's are substantially heavier and give up a little bit of ground clearance, compared to your 30/35 combo. If you build what you have, you've got a low miles, original, treasure that will be reliable and plenty strong for your needs.
Im leaning this way. Just have free d44s to consider too tho. thanks for the advice
