Isuzu dana 44 in tj solid questions

OK so I picked up the Isuzu axle, searched and searched and researched.
But rather then find answers I just hear everyone putting there .02 in why the 8.8 is better. Buy a pre built axle or buy a tj axle....not the droids I'm looking for...I mean information....

I understand that the axle is like 59" and the tj is like 60.5" , now would a normal tj Dane 44 axle fit in the axle I just got?

Common sense tells me no...

So would I have to find a place that sells izuzu rodeo or Honda pasport d44 axle shafts?

Also is the carrier the same so I could use a tj locker?

I'm gonna get a new drive shaft to bolt up to the pinion when I install the sye, and use my control arms to stretch the rear.

Brakes I think I read I can get the part from a Rubicon to adapt them.

Not sure why you would go to all that trouble when the tj units are readily available.
No, the tj shafts won't fit.
d44 carriers are d44 carriers. mind the carrier break. Remember that Rubicon lockers are different. In bearings and carrier beak.

You might want to research the brake compatibility more...honestly, you probably should have asked and read more about this before buying that axle.

why'd you get an Isuzu 44? those have a 6x5.5 wheel pattern and your TJ is 5x4.5 so you'd have 2 sets of rims, or you'd need custom 44 shafts which means if you break one you can't just go to the junkyard and pick up a spare. i thought about this after i sold my Rodeo and it's just not worth it. you'd also have to weld on all new brackets since they're not the same as your TJ. IMO if you're gonna put that much time and money into an axle just buy some 1 tons or something.

Like I said opinions aren't needed here, u can go ahead and search and that's all you get are people just regurgitating what someone else said.

The fact the bolt pattern is 6x5.5 is fine because thats the same as a wagoner d44 front....

Ever thought that if my axle shaft breaks I just get em out of an Isuzu rodeo or Honda passport?..

I seen dozens of them in the junk yard with d44s, how many jeeps with d44s you see? Well you probably seen one with a line of guys behind it waiting for there turn to rape it

You should be able to chop a TJ axle to fit the length and run TJ drums or rotors.

well if you already know what we're going to say and why we're going to say it, why not just prevent that from happening in the first place? all it takes is a simple statement like "i've got a front axle with a matching bolt pattern and gears".
honestly, if you're working on anything Isuzu, these are the guys to go to
https://www.independent4x.com/merchantmanager/index.php
that's where i got all my 'Zu stuff and they even have lockers for the 'Zu 44s. check out www.planetisuzoo.com as well.
and yes, Isuzu 44s are plenty strong for most setups. there's nothing wrong with using an "oddball" axle (by popular standards). just make sure we're all on the same page- we don't know where you're at in your current project, how experienced you are, etc.

Thank you for the links! That is very helpful. Before I build this by trial and error I wanted some info from someone that has maybe done it before....everyone says it can be done but finding someone that's done it is another story.

Anything can be done. I know of some grands with Toyota rear axles(a better, stronger choice btw)
But finding people that have done oddball swaps like this isn't easy. You'd have better luck searching pirate and Google honestly.

There's some very nice, and outside the box, work done around here. but there's other suess with more history of interesting swaps out there.

independent4x4 makes a $360 kit to weld all the tj spring mounts and control arm mounts to that axle. So now I order some wheel adapters and a little drive shaft mod and it should work

Flatlander757 comes to mind, because he did a passenger side drop dana 60 front on his TJ. He had to move everything around.

But The only other time I've seen someone swap in an izuzu 44 is my friend that had a 5.9 Grand. He said it was kind of a pain, but obviously the OP is ready to deal with it.

why not just get an 8.8? 8.8's kick a dana 44's ***. they are alot stronger, yes they have c clips but thats not what fails. all 96 and up is equipped with disc brakes, and alot of them have a limited slip. i got my 8.8 for 100 bucks, limited slip in perfect condition, and just regeared it to 4.56 this past weekend.

an 8.8 has strength that is almost as strong as a dana 60, so why go through the same trouble to do the isuzu dana 44 and an 8.8, when shafts, carriers, gears, etc. are readily available and at your dispense.

What size are the tubes on that axle?

There are several companies that make TJ axle brackets.

Mad4wd has a kit that is $199.

Because he already picked up the axle and is content with doing the work needed to make it work. He already said he's not changing it up.

Or buy an Artec truss - that's what I'd do if I had to do it again.

(OK, the MAD kit isn't quite that bad - everything ALMOST fits. It's still kind of expensive for almost.)
