anyone know any thing about these

Spline count,wms-wms width anything else that could be useful

I got a front 6 lug 44 from a waggie to swap inhto the wifes TJ and would like to find a 6 lug rear 44 to go with it( unfortunatly the rear that came off the waggie was a model 20)

thanks

my rear D44 is off a 95 Isuzu Rodeo...

- 58" WMS to WMS
- factory disk brakes
- 6 lug
- 30spline
- larger than normal axles that neck down to normal size.... this only helps load weight, not rotation force.
- both axles are same length

Overall, it is a normal rear D44 with the exception of the yoke. It has a flange mount yoke... but it can be replaced with any stardard D44 yoke, which is what I did...

the 98+ Isuzu D44s use a thicker ring gear than normal and can be had in 4.10 and 4.30 ratios stock depending on transmission. because of the thicker ring gear however you have to use the arb for the 3.93? and numerically lower gears even tho the ratio is numerically higher. a few of the isuzu guys have run into this problem. IIRC the ARB for the Isuzu is the RD07. One person i know has converted it to full floater, but it took so much work i'm not sure it was worth it, tho it did save him when he blew a R&P in moab in october.

Will these thicker R&P sets work in standard D44s like say a Scout? I know the Scout ARB is an RD07...

Might be a cheap way for me to use the high ratio trackloks I have kicking around on the farm truck 4.30s would be about right (from 3.73) for the 35s.

I have seen them with 4.56s as well. They seem to have a lot of problems with axle seals leaking, but I think there are updated parts avail. for this

If you guys are looking for a pig of a rear axle, go with a Nissan axle. The H233B in the rear of my pathfinder has the 3rd member design, 31 spline axles (I don't believe the neck down at all), gear ratios up to 5.89, and best of all, a ring gear bigger than a Ford 9" (Something like 9.2"). And, if you get one from a 93-95 Pathfinder, they come with disk brakes. Only problem is expense. Anything you want for one is crazy expensive. Oh, and if you get one out of an automatic Pathfinder/truck, it comes with 4.625 gears stock.

What's the width on this axle?

on that note the Isuzu 12 bolt is damn beefy as well. came in 1st gen amigos, and most all troopers til 99 or so. basically all dimensions are slightly larger than a ford 9", and they all came with disc brakes, and almost all had 4.56 gears, tho some 2wd amigos got 4.30s, and a very few troopers got 4.77s. only problem is that the only locker is the ARB (RD44) or lincoln, and there aren't any gears for it other than the 3 i mentioned, tho Tera is taking deposits right now to get a set of 5.38s made.

PS - before some shmuck says it, NO its not a GM 12 bolt!!! its an isuzu 12 bolt. some early rodeos came with the GM 10 bolt, but i'm not talkin about that POS. the isuzu 12 is a 3rd member design.

Actually, depending on what gear ratio you use will dictate what ARB you use in the Isuzu Dana. Since I went to 4:89s I had to get a RD06. Go figure where the dividing line is. :rolleyes: Randy's R&P should have a good handle on this by now. We spent enough time on the phone with Buddy King sorting through it.
As for the Full Floater Conversion, It was worth it for my application. I flat tow my Rodeo a lot and do not want to cause an early demise of my Marlins gear boxes. Not to mention it saved my butt when I blew the R&P, (Dallas was riding Shotgun on that one) Would I do it again for myself? Cost aside , YES. Would I do it for somebody else? Probably not! It was a PITA, but, for me it was worth it.
My next project,(86 Turbo Diesel Trooper 2 door) I'm probably going to go Waggoneer Danas both ends. FF Kits are a lot cheaper and easy to get parts for.
BTY, Around here in my neck of the woods, Waggy Danas are a lot cheaper and easier to find than the Isuzu Danas.

I don't know the exact WMS to WMS of the Nissan axle, but its the size of a light truck axle. It was used in the Nissan Hardbody's and Pathfinders. I would say 58-60" WMS to WMS. Aftermarket lockers are ARB, Detroit, and lockright. Soon, the Eaton electric locker will be available for it. Another thing about the H233B from Pathfinders is they are already setup to receive coil springs. The seats will accept an height early bronco spring.

Now, if you REALLY want to go for strength, go with an H260B from a diesel Patrol (in Austrailia or Europe). The ring gear on those is a bigger-than-dana-60 10.24 inches in diameter. It's a HUGE axle, setup for coils as well.

the isuzu 12 bolt in amigos and early troopers is set up for leafs. in 92+ troopers is set up for a 4 link with coils.

An H233B from a hardbody pickup will come setup for leafs. SOA.

I was going to put an Isuzu Dana in the rear of my 4Runner...yard in Big Sandy (W TX) had 3 of them for $150 each + $100 delivery if needed. I was going to put 5.38's and a spool in it. Went with a 2nd gen 4runner axle that I found cheap in a local yard instead. Kind of wish I had tried the Dana though.

My understanding is Isuzu went with the thicker ring gear so they wouldn't have to mess with carrier breaks. By replacing the carrier with a full locker you should be able to use std. D-44 gear sets.

Yes, it is pretty beefy, but it is slightly *smaller* than a Ford 9", not larger.

And if you want *really* beefy, try the Isuzu NPR axle. There's gotta be a bunch of these things around, some in GMC clothing.

11,000 lb gross weight, 3rd member, full floating axle design, 4.2" axle tubes, 11.5" ring gear, 4 pinion diff and 5.85:1 (and others) axle ratio. Downside is I don't know what, if any, locker options there are for it.

Width is probably a little shorter as I think these are all dually's. Not sure what's available for brakes or lug count/pattern either.

the other kick ass Isuzu axle is the Modified 12 bolt rear found in the '98 Isuzu trooper....



ready for this? hold onto your hats..............

3rd membered axle w/
9.75" (+/-) Spicer produced ring gear (ala D60)
1.5" axle shafts
factory disk brakes
4.56 ratio
width is around 60 ish"
and there is an ARB for it ....... p# RD85



HMMMM...interesting :cool:

Nice...I assume 30 spline?

Damn... talk about polishing a turd.... why make a 1.5" 26 spline shaft?? That's about as bad as the Super35 :rainbow:

hold your horses...i'd have to confirm that count......i'm not sure it's 26...the older isuzu corp 12 bolt axle from like '88-mid 90's is 26, but the shafts are smaller.


i'll check into it.......(time lapse)..................

ok got some info from ARB site + what i knew:



Trooper, Amigo, Pickup (leaf sprung) 1987-97
axle: 12 bolt (disc brake)
1.32" shafts
26 spline



1993 on Rodeo (leaf sprung), late model 98+ Amigo ( coil sprung): V-6 motor only
axle: Dana 44
1.31" shafts
30 spline



Trooper (coil sprung) 1998-99
Isuzu (modified) 12 bolt
1.50" shafts
23 spline



Ok.......so it is actually 23 spline ........................



Hmmmmm................spline count does seem low?
