But will it be

serviceable? One of the things I have always loved about the wrangler (CJ on up to today’s TJ) is I can do 95% of any of the mechanical maintenance and repair ever needed. Any insight on the “serviceability” of the new JK?

while some things might require a bit of learning about, I dont see it being THAT much different. Afterall, it is still a Wrangler.

Of course we can only give educated guess's now. But i dont think its going to be as simple as the TJ. This thing will have traction control and roll mitigation. I would think it would be almost like working on a grand cherokee.

But I am sure it will be much better than working on a 06 Ford F250 with a 6.0 diesel...LOL...

Well, the engine is a carry-over from the minivans of the last couple of years, and the axles, transmissions, and transfer cases are all carry-overs from the current TJ, so I would assume that that stuff will be just as serviceable. The only things that would muck it up are all the sensors for the new gadgets.

I heard the axles were different and the old skids and stuff would not work on the new jk. I always thought a dana 44 was a dana 44?

Yeah, from what I've read, the axles are beefier. (Dana is considering calling it a 45?) Something to do with more or bigger splines? I know zero about axles, but I definitely read something like that on one of the boards.

2007 Jeep Wrangler Chief Engineer Jim Issner has responded to email questions:

6. "I didn't want to paraphrase this next question, it comes from one of our readers with the nickname, 'disturbed': "The number 1 question I have is WHY OH WHY DID YOU GUYS STICK A D35 UNDER THIS THING? "

This is THE most hated Jeep/Dana axle assembly ever produced and to continue to use it under the entirely new JK platform (even with upgrades) is mind-boggling. The D44 or AAM equivalent should have been used across the board for all JKs."




""The Dana 30 front axles have a high pinion design (TJ was a low pinion design) to provide greater gear strength, the housing is stiffer and stronger, and the pinion bearings are larger for improved durability.The Dana 35 rear axle also has a larger pinion and unitized wheel bearings. The prior design had an on-shaft bearing. The axle shafts have also increased in cross section for improved strength. Overall, the axles have been improved over its predecessor. In fact, we are considering different names for the axles since they are virtually all new""




A Jeep spokesman was also quoted as saying that the Dana44's were so much bigger that they considered renaming them Dana45's. I'll try to find that to post, too.

Yeah, what he said.

And welcome, ghostship. If your G-wagen nemesis shows up over here, please ignore him! JeepForum is my way of getting away from that silliness.

The 3.8L has been around longer than that... it's been in minivans for over a decade... it's 3.3L little brother is even older.
