Axle swaps besides Toyota/wag44?

The bearing journal diameters and bearings are different between the two.

RD147 uses Timken # LM104949 / LM104912.
RD157 uses Timken # JLM704649 / JLM704610.

So rear only application?

I would have to agree. 15 years ago I drove like a hammer and was breaking d60 joints, shafts and gears. I’ll now adjust my line and try not to get wedged too badly.

I am back to the early days of four wheeling where I had to drive my junk home. Nothing was worse for my jeep than when I bought my trailer.
 
One of the big values, to me, for the LP-D44 or 9" is how deep you can gear them. old school LP44 can get 5.89 gears, where the newer stuff is limited to 5.38. I know yotas can go 5.71, but always heard that was a bad idea.

To try and build the lightest combo, for strength, I would likely lean towards 9" center with UB30/44 outers. Run the 1350/larger RCVs with 35spl inner and 30spl outers, and can gear them down to 6.50.

A single Tcase with deeper high range or underdrive would be the ticket, to me.

What is the intended use?
 
I have a line on a set of early Ford axles, a D44 front and a 9” rear. I’m going to check them out this weekend and see if they’re worth getting. For $400 I don’t think it’s too bad so long as everything is there and not molested too bad.

More then likely the front has the wedges on the axle tubes which isn’t an issue for me as I have to re-tube the front anyway to move the turd over to passenger side.

I’m looking forward to this build as it’s more therapy for me than anything. I love the dreaming up ideas and figuring things out. I love the fabrication side of it too.

It’s been a while but this was my last buggy that I built everything on it from ground up. It belongs in the heavy axle use thread tho as I built twin steer rockwells for it. It’s somewhere in California now.

If it was me narrowed Chevy 44 like stayed above 5.89 gears. Rear 44 from Cherokee, Isuzu rodeo/passport or fsj Cherokee rear. Not the lightest plenty strong.

Money was no expense I’d go with 6.20 geared 9” stuff.

I like a HP front if I can set it up right. Maybe 5.13’s and max 36” tires

Is the scout D44 weak compared to a Cherokee?

I’m not searching for anything Isuzu.
 
Whelp, looks like no turning back now. Picked up a matched set of Ford axles. D44 HP front and 9” rear. I got everything for the front end it was just in parts. I got a rebuild kit for the rear and new mile marker lockouts.

Now I’m putting my Scout II axles up for sale to recoup my expense on buying these.

I’ll retube the D44 front and make it a passenger side turd.

I just picked up a Chevy D44 front with flat top knuckles for $100 for my Ford D44 modifications. Now I got some more nasty tires to get rid of. Tires are like rabbits with me.

What year? Only the 73-74 Chevy spindles can run the ford “small bearing” hubs.

Don’t know what year it is. Guy I got it from bought a huge pile of 4wd differentials from a scrap guy some years ago and has been selling them off. Either way I don’t think I did bad at $100 for it.

I read where they say you can turn down the big bearing spindles but not positive on that fit sure
 
All else you can just bolt a small spindle to it and sell off the big spindles for couple bucks. I had a D44 I wanted to swap to 8 lug but it had the small spindles so I used a complete setup from a 10 bolt. I can't remember if the D44 was originally a chevy one or maybe J10 I have had too many of each axle.

The 10 bolts he had weren’t flat top knuckles. I’ll figure it out once I get to tearing into them. I gotta buy a 3” OD .375 or .5 wall thick tube for it first, then strip everything down and measure it all. I’m looking forward to doing this part. Of the build.

Pick up another 9” housing and combine it with this donor for a 944 front axle. Probably less work than retubing the hp44 chunk and you can run gears lower than 5.38 along with many other benefits the 9” brings to the table.




Also, I thought this thread was about axle swaps besides a Dana 44.:flipoff2:
 
I originally was going with a 44 from a Waggy or perhaps cutting down a fullsize. At the end of the day I really hate to say it. You always end up with a $$$ under axled unit or a 60. So I'm gonna drag this bitch everywhere until I grow into it...

Yeah I don't think the 10 bolts ever got the flat top knuckles, I just meant I used the spindles off a 10 bolt to match the 8 lug D44 stuff I had. So if yours is big spindle you can always unbolt them and bolt on the small bearing spindles to the flat top knuckle.

As far as I can remember the 10 bolts never got flat tops but always got big bearing spindles and D44 got either big or small depending on year but I think you should already have the small with that chevy axle. I wish my memory was better because I also had the D44 apart in my 72 K5 but I cant remember what it had or that might open up search for the correct small spindles if you do have to hunt them down.

Ok I'll stop with the D44 talk:lmao:

The early (pre 75) Chevy 44’s were small. Everything after was large
 
Been seeing a few CJ5 offset rear 44’s on marketplace (two-piece shafts). I remember a kid in my high school had a Sammy with a offset cj5 rear end.

Positives (imo) are the correct bolt pattern, offset already, bigger diff and narrow width Negative is the two piece 19spline shafts. Can you still get 30 spline one piece kits or full float kits for these? A Mahindra Roxor has essentially the same rear end right? and you can get a 30spline 1-piece and full float for those?

Used to wheel with a guy that ran that with the open knuckle Dana 30. Solid setup under samurai.

I don’t think the warn full float kits are offered anymore. But Mieser makes some billet ends to run front 44 spindles in the rear. Here’s his website.

Yeah I was thinking about that, needs custom shafts right?

I watched a YouTube vid recently that was a feature of Ned Bacon’s flatty that’s on a Roxor frame. He converted the rear to full float 30spl IIRC, I believe On The Rox fab sells that kit. I wonder if it works with the CJ5 offset 44, since I thought that’s the axle the Roxor copied?
 
Rear axle plan for my little samurai. Jeep tj dana 30, narrowed to 52.5”, wj knuckles, Dutchman shafts, factory 3.73s, spartan. Should be fun on 32s

Rear steer and a 1/2” bigger R&P 👍

I have a narrow track CJ7 front 30 housing, steering knuckles, no shafts or spindles if you need to build a matching front

Yes custom shafts. Have to talk to Brennan but I’ve only seen it work with bored Dana 44 Chevy big bearing spindles. As the small bearing shafts didn’t seem to leave enough meat after you get it opened up enough for 30 spline shafts. Maybe he knows an away to keep it 5 lug.

I removed the Dana 30 rear from mine and went to a Dana 44 rear from an LJ because I was regearing and going to sticky roxzillas

Flex testing with one 35 mounted

That's a decent rear end, but I'm surprised you were able to get one. Aren't the TJ guys willing to pay like $1k for those?
