1985 chevy's are passenger drop in front. Not a good swap.

97 TJ Sport OPJ project (other peoples junk) I can't remember the last time I bought a new part.

You can mount Rockwells under a tricycle if you have the money and skills.

In other words, if you have the money and fabrication skills, then yes, you can.

so are you wanting to know what are the "preferred" choices on 1-ton axles?

i would say most prefer

Ford hi-pinion kingpin d60s for the front

for the rear most will also go with d60s, d70s, or 14b ff.

About $10,000 is what you need to put some 1 ton axles under your rig and make it safe to drive. I originally figured around $6k... man was I wrong


What do you mean by "don't go nuts with the money?"


My build thread might be something worth reading... you can see just how much of a PITA it is to put a Chevy front axle(and matching 1 ton rear axle) under a TJ. I don't think it's possible to do it a whole lot cheaper than I did without using POS tractor heims and junkyard bushings and lots of other ghetto crap.

Most Dodge axles aren't worth swapping under... most have either external locking hubs(very undesirable and not easily upgraded to 35 spline... at least not cheaply) and they have ball joints. Most people prefer kingpins(last longer but are harder to service) and there is more aftermarket for kingpin axles(high steer arms etc etc) as it's relatively hard to do a proper high-steer arm on ball joint D60s.


If you're going to swap in an axle that doesn't bolt right on and is vastly different in width compared to stock... don't bother with anything short of a D60 or a Ford 9" w/ D60 outters... TJ and XJ D30s and HP D30s and Rubicon D44s all use the same axle shaft u-joint... which is the main thing that will break when paired with bigger tires and gears. My opinion is it's a waste to swap in much of anything for less than 35s... it was a LOT of work doing my axle swap and I'm damn glad I didn't do it with 3/4 ton front axle first only to want 1 tons after that.

Thanks a lot for the info.
the price isn't really the issue because once started my dad will fund everything.
So i'm looking for the 78-79 f350's

I want to run 38's when done maybe 40's like you.
I would just like to go through this build with the least amounts of mistakes

Well all the info you could possibly ever need is on PBB... there are hundreds of millions of threads about which D60s are optimal. In the ultimate build-ups and swaps thread if you click on them you'll find that about 95% of the 1 ton builds have a 78-79 Ford D60.

Especially when you knowing "ask for it" That was you right?

When you find PBB, you should have at least 6 months of just searching for info about 3hrs a day to keep you busy. If you are serious about building your Jeep like that... then you'll go out of your way to get the info yourself. Not ask for someone to walk you through it. If/when you've been there a while you'll eventually see what I'm talking about. There's a Non-hardcore tech section for a reason.

Just for reference with my D70HD rear, I have 12" of clearance under the center of the diff. It isn't shaved at all and this is on 40s. If you go for 1 tons, it's not worth it to run anything less than 40s.

37-38s are a stupid size to run when it comes to Dana axles... D44s are too weak, D60s/70s make you lose too much clearance unless you shave the hell out of it. 1 tons can easily handle 40s if you have 35 spline everything, so you might as well just go for it.


Check out www.pirate4x4.com

Read everything in the technical section and then go to the forum and just read everything you possibly can. Don't bother posting anything in the Hardcore Jeep section until you are very knowledgable on the subject, and even then you should probably post in the Non-Hardcore. Anything you could possibly need to know is on that site, just search for it.

If you've got funding, don't waste your time building junkyard axles. Just buy some Currie rock jocks or Dynatrac Pro Rocks and get out on the trail. It'll cost more than the 10k, but you can custom order exactly what you need instead of making the other stuff work.

(Basically, I'm saying, unless you enjoy tinkering hours on end in your garage building the axles you can save a lot of time and PITA buying "store bought" axles.

ive been to pirate and ive spend many hours looking.
Just everyone answers differently and there always seems to be a new problem popping up.

My dad does not like the idea of 40's.. idk why?

im building an entire new frame.
Its extending my wheel base and im going to go with coil-overs.

I wanna stay low to the ground and have a lot of clearance.
the Store bought axles are cool but very expensive.
in the end how much more are those than actually fabbing everything yourself?

I might do exactly what you did flat-lander just with 38's and coil-overs.
a 44 front should do fine with 38's? right?

Do you know what size U joints are used in a front Dana 44 axle? Do you know the size of the stub shafts? What about the ball joints?

Compare those to say a dana 30 and a 60 and decide if 50+ hours of sourcing, cleaning, rebuilding, swaping are worth it for a dana 44.

Although I will say a Dana 44 would have addressed the only trail damage I took to my Dana 30 with 35"s which was a busted ring gear. I also lost a stock U joint cap on the highway but never had an issue after going to Yukons.

I wouldn't bother with a 44 front. Still the same weak link as a D30.

If you're going to put your Jeep under the knife for an extensive build like this, do it once and be done.
