Dana 44 12-Bolt Diff

[HOrnbrod]

Anyone know which vehicles these are primarily found on?

IIRC, the Isuzu Trooper or Rodeo (forget which now) had a D44 with a finned cover (maybe the Vehicross, too).  Don't recall if it was std or optional though.

[HOrnbrod]

Thanks, but I meant the 12-bolt D44 rear. The cover is just an illustration.

I think if you look he is on the right path....Rodeo's came factory with a D 44 that was a 12 bolt (I do not know if that is the diff cover in your picture)

 

 

 

Here is one for a 2006 Grand Cherokee (second row last pic)

That looks nothing like your pick i will see if I can find an Isuzu pic

Nissan Titan, some Frontiers & Xterras (manual trans or NisMo/Pro 4X)  has a 12 bolt cover on their D44.  When I googled it, the Nissan boards say it has no common parts with "other" D44's.

 

Oh, and your pic will show up on a Google Image Search under Nissan Titan (or Frontier) Dana 44.  :thumbsup:

That sounds correct. Probably what's called the "Super D44", si?

 

All the 90s Isuzu Rodeo D44s I've seen have the common 10-bolt cover. I looked at a lot of them when I was searching for an MJ D44.

If you look in the menu on the left of yxmj's link and click on "Nissan" you will see what they're calling a Nissan 12 bolt - that's the Nissan D44.

I think i might have 1/2 the answer...The Isuzu rear end PRIOR to using the D44 was a "Corporate 12 bolt"...not a Dana...switch to D44 later on...... and as said above that first Nissan cover looks like the bolt pattern is the same.

I just discovered that the Frontier rear end come with a 4.09 ratio and a WMS width of 62.5

 

That would move the wheels out 1" in each direction for the rear.

 

 

What are the chances I could get new axles for the Frontier with 5 on 4.5?

[HOrnbrod]

That's it. Must be a Nissan-only axle. Strange........

[a4xnut]

The IH Scout II's Dana 44 is about an 1" narrower on each side.  It runs 5x5.5" bolt pattern (same as a CJ).  Due to the hub center's size, it can't be drilled to the MJ's 5x4.5" pattern, but you can get adapters to change it and with them, you'd be about the same as stock.  The Scout's rear axle doesn't come with disc brakes, but they are bigger than the Jeeps - and if you get a '75 or newer, they are bigger than the pre'75 models.

 

I used one from a '73 Scout II in my XJ (partly because it was scavenged from a rusty parts rig for free), but I didn't use adapters because I wanted to keep the 5x5.5" pattern and with the different offset typically used with 5x5.5" Jeep & Scout & Bronco, my track width actually increased with the narrower axle.  I did have to address the front though, otherwise I'd have to carry two spares.  I chose to build a hybrid full-floating high pinion D30 out of my OE axle.  http://www.4x4wire.com/jeep/tech/axle/xjupgrades/

 

Why not just run an Exploder 8.8 with discs?

Places like Moser engineering will make what about ever shaft you want or convert your current flange.

I had Moser make my custom D30 inner axles.  I was disappointed the only guarantee they gave was the axles were made to the dimensions I ordered.  One of them failed only a few weeks (two wheeling trips) later.  It's not like the GM 2.8 V6 overpowered it.  I had never managed to break a stock shaft.  The Moser unit broke right behind the u-joint yoke.  It could have only been a cleaner break if it were cut with a laser.  I'm pretty sure there was a process failure in heat treatment - or a complete lack of it.  Fortunately, it was the short side and it happens to be the same length as a Scout II D30's short side, which I happened to have.
