Front rubi 44 locker in rear D44

Ok, will a rubicon 44 front locker work in my rear D44? I know it is a half a*$ed 44. kind of a mix of a d30 and a d44, but will it work? Also I have heard the term 'thick gears' and I know rubicons use these. So will stock D44 shafts work with a rubicon locker and gears? either front or rear. I am not looking at buying new or anything, that would be stupid. Have a chance to get a pretty good deal on a used rubi locker and have heard the front lockers are stronger then the rear.

Won't fit. The Rubi front 44 is far more D30 than 44. Front lockers are not typically stronger than rear lockers, they just see about 50% less torque. I suppose it could be stronger if you had an old waggy 44 up front and a D35 in the back.....but that wouldn't make much sense.

Ya, I am not giving up on this one easy. It is stronger in the fact that it doesnt act as a limited slip, and something about the helical gears. Not sure on all the details. Thanks monday, I'll give em a call tomorrow. Does anyone have experience with or have done this themselves?

We see a lot of Rubi owners replace broken rear units with front units.
this was from another thread, I tried to get the OP to elaborate, and also tried to send him a PM but was not able to do so. Does anyone have any more info on this matter

I haven't been able to bust my rear carrier and I just put 37's n another and wnet and beat the crap outta it,

they are prolly hamering on em before it's actually locked in, that will toast em...

I want your factory 07-up take-off/thrown out JK front/rear Lower Control Arms! Bent ones are perfect also as long as the bushings and cold cut rings are in good shape/useable

Yes the front will fit. You will have to shave .100 off of the carrier bearing cap that is notched for the airline. That is done to let the shift collar have enough movement to let the locker unlock and go into open diff mode. Not doing so binds it up and the locker won't unlock.

You will also need thick gears or a spacer for your regular gears depending on the carrier break and what you have.

As far as being stronger, there is some merit to that argument. Given that the limited slip portion of the rear locker is typically what fails and takes out the rest of the locker, not having it is a good thing.

MrBlaine:

I have a rear Rubicon locker with the thick gears and was wondering what it would take to put it into the rear Dana 44 on my 01 Sport.

I've heard that the rear locker is a bit wider and the standard (non-Rubicon) Dana 44 housing would have to be somehow shaved to make room for it. Is this true and how would one go about doing it?

I'm 99.99 percent certain you can't get the Rubi rear locker into a standard D-44 non Rubi housing. The front barely fits with some modifications to the carrier bearing cap and the rear Rubi locker is wider.

In the event that the .01 percent matters, get in touch with Gearman on POR and send him a PM. He will know for certain.
