This topic comes up often in various forms. I'd like to see one good thread that could be used for a NAXJA quality tech article or possibly a sticky; one that any other 4X4 site would gladly refer to.

Let's try to keep this ON TOPIC and prevent muddying it up with unrelated questions or opinions, like why not build a D-60, 9inch etc.

One main priority would be to make it as "Bolt in" as possible. In other words, keep it set up for the original style suspension and track bar mounts. This axle should be able to be pulled from one XJ (or TJ, ZJ etc., for that matter) and moved under another with as little work as possible.

For those who have done it... what would you do the same; what would you do differently?

Some of the items that should be covered:
Housing; whats the best donor vehicle and why? High Pinion or Low Pinion? We know that the HP is stronger but can it be made to fit in an XJ with 6"-7" of lift? Keep in mind we're using the 4-link bracketry. I'm thinking the LP is strong enough for most applications since a 44 front is most likely going to be used with 35 to 37 inch max tire sizes. Larger tire guys will probably be considering the 60.
Housing dimensions; What width, how much to cut and which side? Dimensions that allow the use of available stock length shafts would be very desirable.
Lockers; this should be kept to a minimum for the sake of this article since it's a matter of personal preference, plus the fact that there are many more types coming on the market now and time will tell which will be reliable.
Axles; Seems like Warn has the best rep so far but if you feel differently please chime in. Axle joints are another item that will be a matter of personal preference. 760's, CTM's, OX, etc. all have their place.
Inner C's; If you're going to build it from scratch you might as well do it right. Cutting and rotating them should be done now. Anyone who has their Castor to Pinion angle specs per lift height would be handy. Priority should be given to castor of course.
Knuckles, Brakes, hubs etc.; which do you prefer, and why?
Steering; This could be an article all by itself but let's at least touch on the basics with the emphasis on a street driven rig. Leave the Hydro set-ups for another thread.

With the amount of talent around here we should be able to come up with a great D-44 build-up. Let the fun begin. TC

The ultimate 44.....

I started with a Tera 50 housing(basically a fancy HP44) that I got off the forsale board. The only thing special about it is the pumpkin itself. Anyway, if I were going to build the "ultimate 44" this would be my recipe:

Tera 50 w/ 3" .500 wall tubes(like mine)
Crane D60 kingpin inner Cs and and knuckles
35spline ARB
Superior 35-spline shafts in and out
Warn lockouts
CTMs

The bracketry will be the same for any front axle. Buy your brackets from RE or make them(or mix and match which is what I'm doing), either way it's not that big a deal to do the bracketry.

I know you said you didn't want D60 tech in here, but hey, you said the ultimate 44, and I believe an axle is defined by its differential, not its knuckles :D Seriously though, in that setup, I think the R&P is the weakest link. And yes, what I described is possible thanks to the wonderful aftermarket.

not the ultimate, but possibly the Ultimate Budget D44 is what I did:

'80 Waggy LP D44 - $90
Chevy hubs and lockouts - $0 (friend)
Cut and turn knuckles - $5 (cutting/grinding wheels)
Used Spicer 4.88s and carrier - $75
flat-top knuckle, milled, drilled and tapped with ball-joints - $100
Parts Mike steering arm and hardware - $110
Lockright - $100
760x joints tack welded in - $40

Total; just over $500 into an axle that should be very reliable on 35s

this is setup with leaf springs, so no cost for brackets

there's also a good D44 thread going on over on the Jeep section of the Pirate board, much discussion of 33 and 35 spline ARBs, D60 outers, etc.

If I had it to do over again, Terra 50 housing, 300M D60 shafts, outers and CTMs. Shafts and housing can be made custom length to keep pinion at same position as stock so it can be run with 4" of lift or maybe even less. My HP 44 (Ford) runs stock pinion position with 5" lift and rarely the pinion U-joint hits the exhaust pipe.

Well, I don't see much point in making it bolt in if you're going through the work of building a D44. One of the big benefits of a D44 is the hy-steer arms on a flat top knuckle, which means you'll also have to raise the track bar mount on top of the axle tube, and move the sway bar links up. Since you're welding on all new bracketry, might as well move the axle end control arm mounts up a little higher for better angles. Also, the spring perches can be raised a few inches to build in a little lift, meaning fewer spacers, and you might as well reposition the shock mounts upward a little for more droop and outward a little to clear the frame with the extra droop.

So, to me your parameters for building the ultimate D44 are too limited. Might as well do what Mark said and stick with the D30. :D :D

Here's my sort of ultimate D44. I tried to go with the 33 spline axles and D60 outers, but the lockers were not available by themselves, custom knuckles weren't available then, and Currie said the cut down and resplined D60 axles to 30 spline were not holding up even in Toyota's. So, I went with Warn axles and CTM's. I decided to use off the shelf Warn axles for an '80-'84 Wagoneer, and cut the housing down to that size, which gave me a WMS to WMS about 3/4"-1" wider than the stock XJ. I like the Ford high pinion housings. The D30's (except the unlucky real late model guys) are high pinion, and I see no point in spending time and money and going backwards to a low pinion. The issue isn't the r & p strength, it's the driveline and yoke clearance, both from rocks and from potential binding due to severe droop. All of my bracketry is custom. I didn't see the point of building a new axle and leaving everything in the stock location. All of the control arm and track bar mounts, either bushings or johnny joints, are 2 5/8". It's not difficult to get 3" boxed tubing 3/16" wall, which gives an ID of 2 5/8", and use that to make all of your brackets and mounts. Since I'm always thinking about clearance, I also shaved and plated the bottom of the diff. Here's a couple of pics:

Richard, what you've done is an excellent example of what I was hoping to see. It's not that far from being "bolt in" (Hope you didn't think I was looking for "bolt ON" type mods), in other words once the front end is completed it can be swapped from one rig to another without major chassis mods. The rasied bracketry on the housing should still work on someones lifted XJ when they decide it's time to move up to the 44. Most folks build their rigs in stages and the change to a 44 usually comes after the lift and suspension mods.
The only concern I was wondering about with the HP was clearance problems without going to excessive lifts. How much lift are you running and did you need to limit up travel any? The HP 30 R&P may be close in strength to a LP 44, but the upsides are the stronger housing and knuckle/ball joints plus axle options (locking hubs). This is why the Rubi fronts aren't really much to get excited about. A cut and turned LP 44 like MAD built is a good Budget front anyone could copy. By rotating the pinion up the clearance at the yoke is improved a good bit as well as the driveshaft angle.
Although it's likely out of the range for most of us, how much are the Tera 50's new?
Maybe instead of "Ulitmate" (which is subjective) I should have asked for "Recipes for a D-44 front". :)

There is no reason to go through the trouble of building a front 44, and using a low pinion housing. Everything about a high pinion housing is better.

I have to ditto what CRASH said. With the parts that are available for a D30, I'd stick with it before I went to a low pinion D44. The cost of the D44 build up is the same whether you do low or high pinion, so do the extra work and spend a couple of bucks more and get the high pinion. There are no clearance issues that I can see with the HP. I have about 7.5" of lift, my bumpstops are raised about 3.5" and I stuff it to the bumpstops. I realize that Waggy D44's are fairly easy to get, but the HP is important. I'm not into getting a D44 (or anything else) because it's cool, only because it will work better, and high pinion works better than low pinion.

What mad maxj built is pretty good on a budget, and he has the hy-steer and bigger brakes, but out here we break Spicer axles like tooth picks so I'd still rather have a D30 with chomo axles than a D44 with Spicer axles. Just like the high pinion, I don't think it's worth building a front D44 and not going to chomo axles. Now, in mad maxj's case, the Spicer axles hold up much better on a leaf spring front end than they do on a link front end....but that's a whole 'nuther discussion.

Except that HP housings are getting a little more pricey and a little bit harder to come by. Also, you don't have to cut down the waggy 44's. This is nice for the folks that don't have the ability or courage to do this sort of work. Tim, I just got done building a waggy 44 for my buddy David. We cut and turned the knuckles to 5* castor, built in appx 1.75" of lift with the buckets and I'm doing the goatman copycat 3 link on it. It's sitting out in the shop if ya wanna come by and check it out.


Our meeting is tonight at 7 and we're doing a cookout so come out and grub. We'll probably get a few folks stuck and broke out back too:party:

I agree with your points about a waggy 44.......but this is a thread about the "ultimate D44". :D

BTW, if I remember correctly, I set my pinion angle at 10* and my castor at 5*.

In defense of my LP D44: It was cheap and available, 1.5 years ago I found a 77 F150 D44 at Pick N Pull and got it for about $100, then I turned around and sold it for $550. There's no way I was gonna pay anything close to that for a HP. And with the pinion rotated up, I was surprised to see just how high the yoke is now. Yes, the HP is better, and I'm still keeping my eyes open to find a bare housing for cheap.

the main reason I actually did the D44, is that I knew I needed to upgrade the D35, and I think the Toyota axle is the best thing going for 37" and smaller tires, so I needed something up front to match the 6 lug. This was a good excuse to upgrade housing strength, brakes, hubs, steering, etc at the same time. I had NO money invested in the D30 at the time, so no reason to build that at all; 3.55 gears, 260x joints, no locker.

Yes, I will probably break a few shafts at Rubicon and Fordyce, and I will carry spares, but I'm 19 (almost 20!) and that's just the game I have to play for now. I'll just see how it goes and keep throwing money in the piggy-bank for Warns.

as mentioned above, it isn't as much strength issue as a clearance issue. but i think people would be surprise how high the yoke is on my LP D44 that I cut and turned the knuckles on.

For any guys out there with a HP D44, measure the distance from ground to bottom of the diff, then the distance from ground to lowest part of the yoke, then subtract to see how high the yoke is above the bottom of the axle. I'll do the same on mine, and we'll see how close mine is getting to HP yoke clearance

Sean, one of these day's I'll make it over. As far as the HP being over rated, I wouldn't have put it that way.If you can find/afford one it's definately worth shooting for. I'm sure someone here may have seen one fail but I've gotta admit that all the broken R&P's that I've personally seen broken were the result of something else breaking first or improper installation. Mad, you make a number of good points, there is a place for the LP in some cases. Like I said, I shouldn't have used the word Ultimate, to restricting. TC

I measure 9.5" from the bottom of the pumpkin to the ground. 16" from the bottom of the pinion seal area to the ground. This makes for 6.5" of dimension change with my HP D44 sitting on worn out 33x10.5 AT's. I don't know the pinion angle, but it is pretty much in line with the driveshaft looking from the side. The Jeep has about 7" of measured lift. Anyone that would like to gain some HP 44 into an XJ inf. is free to look at my article on http://www.madxj.com. THE main reason I built my D44 was to get locking hubs so I could unlock them and have some semblance of smooth highway driving! I was NOT about to pay WARN prices for their conversion when I could get the same thing in stock parts and also get all the other advantages of the 44. One thing that did bother me is that even though I spent great care to rotate the pinion and get some caster, I still have vibes with the front hubs locked. I theorize that the vibes are coming from the fact that my pinion is shifted to the drivers side somewhere around 1.25" compared to stock. I'm using an early FSJ short axle shaft combined with a late FSJ long axle shaft with Chevy flat top knuckles and FSJ outers. When lying under the jeep, one can see that the driveshaft runs angled out from the transfer case. However, I just unlock the hubs and motor on smoothly. I ran this axle at 5-6" of lift with no clearance issues. In fact, since the pinion is shifted, there is less chance for the driveshaft to hit the header...which is a Borla unit on my rig. I have also gotten death wobble with this system. I don't know why, but a steering stabilizer helps quite a bit. Oh yeah, I built a jig that aligned with the control arm mounts on a D30 and then lowered the axle tube location in the jig by 2" which has the effect of locating the mounts 2" higher on the D44. Jeff

I run the same shafts/offset as you Jeff, and don't have vibes all the way up to 55 in 4 wd. Hell, I ran halfway across Nevada at 80 mph to Moab with the transfer case locked accidently in 4 wd (linkage issues) and only had mild vibes.

My caster is set at 6 degrees and the pinion is 13 degrees from horizontal. This is about perfect for 7" of lift and the T-case moved up near the floor.

i broke a LP d44 this past new years on lower 2 at tellico. granted i did a 3 ft wheelstand with the drivers side tire and came down spinning, but it let go right where the shaft necks down before the splines. i built mine on as much of a budget as i could, being a broke college student a couple of years ago.

ps - that was after 5-6 GOOD trips to tellico, aka hammering it on all the harder stuff there.

That is exactly why I went with the LP waggy 44 option. Now that I have more experience, I'm not sure if I would have done the same thing again or not. I do know that I probably would have taken the time to cut the knuckles, turn, and reweld them for a better pinion angle....but it doesn't really matter with my 6" lift and the locking hubs.

Mine ended up being as close to bolt in as possible. I built it up using the measurements from the 30 to locate the control arm mounts, trackbar mount, and coil buckets. I then took the 30 out....sold it....and put the 44 in. My friends and I were able to bolt the 44 up in a little over and hour. Very cool.

I have more stuff about it written on my site here:

I'm the loser with the D44 that meets your "swap from Jeep to Jeep" criteria. It's a high pinion Ford at stock width (3.75" BS rims). RE TJ brackets, high steer knuckles, trackbar mount raised to level with draglink, standard hi-steer crossover steering using TRE's, Warn hubs 5 on 5.5, rotated knuckles for 4 degrees of caster (I love the slightly lower caster with radius arms). Warn inners, spicer outers (fuse concept - will be changing this). This was 3 years ago.

I have 8" of lift, about 13 degrees of pinion angle, and I can drive in full time 4wd at 70 mph vibration free (the pig is just amazing in the snow). This is about as "factory" as you can get while still having the good stuff. As long as you took my trackbar, this would be bolt-on with no additional mods except reaming the pitman arm for the larger TRE and drilling out the trackbar bracket for the heim. Hook up any control arms you want. Minimum lift is about 5.5" (for oilpan clearance).

Today I would get the exact same axle, but add about 1.5" of width (same for the rear of course, although stock width with 3.75" BS rims works really well). I'd be building the suspension and bracketry from scratch. I'd use aftermarket hi-steer arms with heims in the steering. One of these days I'll probably rework it, since the basics are in place. For now I just need a limiting strap.

So my D44 is a really beefy D30 replacement that can handle the road miles (and this was exactly what I wanted at the time) and grab a few more rocks on the trail (it's not shaved). It *is* the ultimate D44 front end for those who haven't yet thought outside of the factory suspension parameters, which I hadn't when I built it. These days, you'd be much better off spending your money in ways that totally disregard Jeep to Jeep swaps.

on my best friends 5.3L Vortech powered 1989 YJ running 37x13.00 Boggers. 1 1/2 years zero problems and zero breaks. In fact now that my friends gone to D60s he has had alot of problems running 42" TSLs. His brother also used the same setup on his CJ powered by a Chevy 350, he is now on Rockwells with zero problems. I don't think an XJ with stock power would have a problem if these guys don't.

Here it is now so yeah it gets used:

I would have to dissagree w/ the over rated part. Its not so much of a strength issue....I would have gone w/ a low pinion, but with the driveshaft being so short & wheelbase not helping, the driveshaft gets too much angle (taller lifts). Thats why I chose a HP, you cant complain about the added bonus (strength of the ring/pinion on the forward rotation either :) )

Richard, do you experience a "dead spot" in your steering because of the way you have tied the draglink into the tie-rod? I just finished setting up the steering on a friend's WJ with the 85 Blazer TREs that uses the hole in the TRE to tie-in the draglink(like Andy's a few posts up), and he's got a noticeable deadspot from the tie-rod's TREs rotating under load. Just wondering if you experience the same condition and if there's anything to do about it besides a true cross-over steering. Thanks

This photo was used without my permission. I'm calling my attorney.

I get very little rotation when turning on level ground, but it does rotate a little in the rocks. My drag link and track bar are pretty flat when sitting on level ground, so there is only a small vertical load on the joint:

Well, since my D30 gave up this winter I decided to spend my time and efforts on a D44 buildup vs putting similar monies back in to the D30. Started down the EB 44 route but found a '77 F150 with a HP44 so now I am going to narrow that.(My experience on finding an HP was just following up on every lead you get. Truck ended up being at a yard 3 miles from where I work.....sometimes you just get lucky).

Q1: For those of you that have narrowed full width HP axels, what have you narrowed to?

Popular route seems to be to narrow to a waggy width so the shafts aren't a custom length. From what I have read this puts the drive shaft and pumkin in a good location similar to the D30. I am at 6" of lift and not interested in going a lot higher right now(one of the reasons I didn't stick with EB setup(other than LP vs HP) was the fact that the pumpkin being more centered required more lift to avoid oil pan/exhaust issues....sorry FarmerMatt).

Q2: XJ Dana 44 rear vs Ford 9 inch?

Also am having the debate with myself on the rear. I have the full width Ford 9 inch from the F150, plus an EB 9 inch housing. I can swap the 31 spline 3rd member from the full width over to the EB housing, put in alloy shafts and not have to change anything on brakes to go to 5x5.5. If I stay with the XJ D44 I have in the truck now I will need to either get adaptors to go to 5x5.5 or get new shafts and drill my drums. Opinions on which route to go would be appreciated. I see advantages both ways, thus the debate.

Also am having the debate with myself on the rear. I have the full width Ford 9 inch from the F150, plus an EB 9 inch housing. I can swap the 31 spline 3rd member from the full width over to the EB housing, put in alloy shafts and not have to change anything on brakes to go to 5x5.5. If I stay with the XJ D44 I have in the truck now I will need to either get adaptors to go to 5x5.5 or get new shafts and drill my drums. Opinions on which route to go would be appreciated. I see advantages both ways, thus the debate.
narrow it to Waggy length to be able to have junkyard shafts and off-the-shelf Warn shafts available

run the 9" unless you've already put gears and locker in the XJ d44

Richard, do you experience a "dead spot" in your steering because of the way you have tied the draglink into the tie-rod? I just finished setting up the steering on a friend's WJ with the 85 Blazer TREs that uses the hole in the TRE to tie-in the draglink(like Andy's a few posts up), and he's got a noticeable deadspot from the tie-rod's TREs rotating under load. Just wondering if you experience the same condition and if there's anything to do about it besides a true cross-over steering. Thanks

No, I don't have any dead spot. I do have a slight tap/clunk if I don't keep the drag link centered over the top of the tie rod in the direction of the push/pull. I also off set the heim joints on the tie rod so the tie rod can't pivot much, but this is precautionary. I don't have a dead spot even if I don't do that.

My take on the subject is twofold. One is that you don't want much angle on the drag link, so it pushes mostly sideways. The other is that even if there is some sideways movement (rotation of the tie rod) with a nearly flat drag link the amount of steering wheel movement to overcome the rotation is very slight and should be virtually unnoticeable. I think having the drag link mounted on top of the tie rod, rather than on the side, helps this whole scenario to some degree. Since there is always some angle on the drag link it's better to push down a little on the tie rod from the top rather than from the side.....from the side guarantees rotation before the tie rod moves. However, the heim joints/tie rod ends can be offset to eliminate most of the rotation, so it's still not much of a problem. With the tie rod going knuckle to knuckle there is very little misalignment required of the joint at the knuckle when turning, just the amount that the knuckle causes, so it doesn't hurt to offset the joints some.

Anyway, I don't have any deadspot. Once, I tried a YJ steering linkage, and I got rid of it fast because of the big deadspot it had.

Q1: For those of you that have narrowed full width HP axels, what have you narrowed to?

Popular route seems to be to narrow to a waggy width so the shafts aren't a custom length. From what I have read this puts the drive shaft and pumkin in a good location similar to the D30. I am at 6" of lift and not interested in going a lot higher right now(one of the reasons I didn't stick with EB setup(other than LP vs HP) was the fact that the pumpkin being more centered required more lift to avoid oil pan/exhaust issues....sorry FarmerMatt).

Mine is narrowed to the width of later model waggy...80-84....and it clears everything very well. It's 61.5" wide, which is 3/4-1" wider than stock XJ. To calculate how much to remove from the tubes on each side, I took the difference in axle length specs from the waggy to the XJ, and thats how much I shortened each side.....pretty simple.

Between the D44 and the 9", that's a tough call. What tire size are you going to run? There's not much difference in axle shaft strength between 30 and 31 splines, not enough to sway you one way or the other anyway. If you're going to get alloy axles, going to 5 on 5.5 is easy on the D44, so no real advantage there to the 9", only thing you'd save is having the drums drilled. Are the brakes on the 9" bigger than the D44, like maybe 11" vs 10"? That could be a slight advantage for the 9".

The 9" pinion is lower than the D44, but I don't remember how much. Any advantage here would depend on the tire size you're running, bigger tires and I wouldn't worry about the pinion height over more strength. Running 35's, I'd say stick with the D44. Running 37's or larger, I'd say go to the 9" for the stronger gears and very slightly stronger shafts.
