Swapping rear Dana 35 for a Dana 44 on 07 JK

WJCO said:

I assume we're talking front? Pretty straight swap with basic hand tools. How did you get a jk with a Dana 35?

Hello fellow Jeepers. I am still new to the forum. Don't get a chance to post much. I need some help I have a 07 JK X with a D35 I purchased a D44 off a 10 JK X. I have never done a swap but I have worked on my spider gears thanks to this forum. The question i have is what tools do I need to do the swap? Also my D35 was 4.10. The D44 I purchase is 3.73. I am pretty sure I have to swap out the carrier and the spider gears but just want to get any input on what brand I should look for. Thanks for all the information in advance looking forward to posting more. I will be posting pictures Tuesday when the d44 arrives to my house.

I've read that too, never seen one although I remember seeing a 2wheel drive 07. JP mag tried to say a couple months ago that the 35 in a jk was a myth

Edit: Title says rear. So you have a rear 35? That's a new one...

You will need to regear the axle to match the front ratio. I would assume you can't do that and neither can I or most other people. If it wasn't for that the swap would be pretty easy

Carrier and spider gears will not need to change. I regeared from 3.21 to 488 and have the same carrier

The axle should just bolt right up. That's the easy part. You will NOT be able to use the gears in your Dana 35 on your new 44. If it were me, I would use the opportunity to have a locker installed as there would be no extra labor involved and can be done at the same time as your re-gear. You can always remove your front drive shaft and drive around in 2WD until you can do this.



Yup, this. VENGEANCE came with a factory Dana 35 rear axle.



Just goes to show how much JP knows. :naw:

Assuming you're still going to be running a Dana 30 front axle, I personally would not run anything more than a 4.88. As far as brands go, they are all made by the same company in South Korea only packaged in different boxes.
