I found those Mopar axle assamblies on the 4Wd hardware shop.

Has anyone installed such an axle into a Tj? how about gear ratios, are there 4.56 on the market?
i think i have to cut all original tabs and brackets and install a set from my old D30 axle. How about the steering links?

The price isnt bad:

:smokin:

uhh....where to start?

you do realize that for $3k you could probably buy an excellent condition dana 60 and 14b, and probably have enough coin left over to have them freighted to italy?

or some mog axles?

or for about 4k you could probably build your own currie axles?

ok, maybe not currie axles.

this is retarded.



:shaking:

edit: my point is, there are a zillion better options out there for that kind of money.

I will run MAXIMUM 37" tires. I think those axles will handle them pretty well.
2nd is that the are brand new, it isnt easy for us in the "old-world" to have D60 ore Gm14bolt parts, neccesarz to rebuild a used axle.

What do the JK rubicon owners think about the strength with 37" axles in competition use?

I know, its no bolt-on!
But the other option, here in europe is to use some Jap-axles like Nissan.
This is a lot more complicated to fit them to a TJ....

We dont have D60 or 9" in our yunkjards, just some import minivans and other poor junk............:(:shaking:

It just look pretty now! :flipoff2: Right noe im running A fullfloating D35 and a HP D30 both with the famous VacuumLocker from K&S. 34" tires and competition use, No problems!

I will find some other options... :smokin:

That was my point! I think you can do better than a JK axle, even over there. The problem is those axles haven't been proven. I see lots of JK's running 35s and 37s but none of them do any hardcore wheeling like others do. Even if they are a little beefier than a TJ 44, they're not going to have the longevity of a 1 ton on anything bigger than a 35. Good luck with finding what you need :)

@Tomster: There will be an JK-R kit available from superior axles, it contains a 35spline locker for the rear and 35spline axle shafts. Then you swap the JK rear locker to the front w/ the 32spline shafts.

If I can get my handy on a set of this axles and tires (from a 07 JK Rubi) than this will be the way I´ll be going.

Hope to get more information about two more sets of axle in the next 4-6 weeks.

Perhaps this could help w/ the swap: http://www.tntcustoms.com/webV5/Dana44Swap.asp

I think I´ll have to talk to Ralf about the swap once I get the axles because no one over there in Germany seems to have any experience w/ this axles.

axles.
If you are talking about moving the rear jk elocker to the front in a TJ d44 housing it could be tricky. The pinion is bigger in the JK D44 (and d30) and they use thick ring gears which means the carrier is for numerically lower gear sets, plus the ring gear bolts are larger in the JK carriers.

People do use regular D44 carriers for numerically lower gears and drill out the bolt holes but I'm not sure about going the other direction.

along with the suspension brackets not fitting I am pretty sure the bolt pattern is different too. 5x5 I think. so pretty much you have a crap D44 that you would have to do a lot of work to get it to fit into your Jeep. Just get a Ford Dana 44 or search for some matching D60s

Sounds like you have pretty much made up your mind that this is what you want to do. I agree with the 60/14 swap, but that is what this whole board is about. Trying new things in different rigs and testing it out. I say, if you want to do it, put em in, and report back on how they do. If your 30/35 have held up, these might do the trick. Good luck.

x2 if for some stroke of good fortune your keeping your D30/35 alive, then go to the new D44's and report back.

I'ld strongly recommend the aftermarket shafts = at least 31/32 spline front and 33/35 spline rear. Of coarse I think you should run the stock stuff till you break em though!! :D

There are many vehicles that do not need a 60 front or a 14 bolt rear. Fact is the JK rubicon has the strongest internals of any 44 built to date (except possibly the Titan rear)

A 44 requires a hell of a lot less power to push around than a 14bolt and offers a bunch more clearance. How much are selectable lockers for a 14bolt and a d60?

I just bought 2 '79 60's for my TJ. I got to get gears, lockers, set up kit, brackets, steering, another job and learn to weld. O and a bigger motor to push the fawkers. That doesn't include building the suspension links, working the fenders, tires and wheels, Full tank, bumpers and a stronger cage to keep me safe in an upside down heavier rig.

I say make a bracket jig before cutting off your old brackets, cut them off, weld them on using the jig you made. Then maybe some how use one of your old yokes to make some sort of booty fab flange connections. Run stock new rubi rims to suck the tires in alittle more and your set. O and then buy some new tires no bigger than 37" cause of the 4.10, and beat on 'em. You'd still only be in about 4and one half g's front and rear. DOIT.

The front lower arm pockets both measure 30" inside to inside on the TJ and JK axles. The front uppers are about 1" wider on the JK axle at 18.25" or so on the inside. Shock mounts are different but would probably work fine, the front track bar mount is above the bracket so no more interference at droop like the TJ axle. The JK axle also uses a full tie rod and highsteer passenger side knuckle which may be an advantage for some.

The rear axle has no common mounting points but as others have said RE and others offer bracket kits. The rear would also require brake link mods since the JK uses independent brake lines on each wheel for the ESP.

The JK axles are 3" wider (64" wms to wms, I think) but like others have said, they are 5x5 pattern so you would have to change wheels, WJ use the same wheel pattern. The only other down side I would see is the pinion flange would need an adapter since the factory uses a ball style cv driveshaft. RE has 1310 driveshafts that adapt to the OE cv flange.

Thats all I got...

The JK Dana44 are better than any D44 put in any stock vehicle including the Bronco. Add in the fact that Rubi JK axles come with lockers front & rear disc brakes the price is pretty good. The new lockers also have better actuators and pointed out the front outer axles a 32 spline. These are better than many of the shelf "custom" axles out there plus the rears are set up for coil springs. These are a very good option for a dd but probably not for a trailer queen. Superior does have alloys available for them.
