Is there a JK/JL axle bible?

At this point with all the different info I would love to have the cash and round up a few versions of the axles just to weigh ****. For my D30 front Toyota rear project I'm starting to wonder about the JL super 30 with aluminum knuckles, I am remembering correctly that was an option right? Narrow it a bit to match the XJ D30 \1st gen taco 8.4" width like 60-60.5". That or I guess match it up with a wider Toyota rear like 1st gen tundra and then run a deep backspace wheel.

I’d just use JL axles front and rear and run deep back spaced wheels.

Have you or anyone on here found JL takeouts that were good and usable? They are astronomically priced if I’ve found any. Like $6k asking price for used JL axles. For that kind of money I’m back to 99-04 superduty’s

$6k is insane for a pair of stock any size axles.

For rubicon or standard?

I want to say '84 Bronco II paid around there for his pretty built rubicon axles.

I have seen low mile JT rears with lockers for $2k on ebay. Doesn't seem horrible for something that's barely used.

I got a JT rubi rear housing with locker but no shafts for $150.

Rubicon.

My dad has an 05 LJ sport that’s mostly stock. I always thought one day I’d score a set of rubicon take outs from any generation and we’d long arm it when we swapped them in. It’s been 20 years and even doing what we do I’ve never happened onto a set of rubicon take outs except where the guys want $4K and up. Just recently someone posted a pair out of a JL on marketplace for $6500 bucks. That ad is gone so they must’ve sold. Maybe not for the full sixty five but I bet more than I was willing to pay for them.

I just sold a set of JL Sport Axles (Super 30 front M220 rear) with less than 1,500 miles for $1000. I bought a set of Upgraded Rubicon take outs (RCVs, trusses, etc.) for $4,000. When I was shopping, I saw several sets of Rubicon take outs in the $3,500-$4,500 range from people upgrading to 1 tons.

This is what I’ve seen in a jeep club that I run around with. Jl/jk guy gets tons then the tj/lj guy swoop up their axles. I still wan there to be a “mid weight axle” solution but not for more money than one tons.
 
Thats really interesting! Im curious what your thoughts/reasoning is on your build vs what most of us proposed here. It seems like most of the hybrid talks here are of using the jk/jl outers with 9" centers while you are doing the opposite. Do you feel the outers are a weak point? Or do you have specific clearance needs that make the m210 more logical? Or just looking for a bigger bolt pattern to match a full float rear?
I have no first hand experience with the strength of these axles, I probably barely even classify as a wheeler lol. I just like to build ****. Originally was gonna do a hp44/60 outers and the weak link be the pinion, but then these axles came out. That's how long I've been "working" on this lol. They're just interesting to me, massive chode of a pinion vs a D44, inner pinion bearing and ring gear side carrier bearing are .5" larger OD vs a D44, and the super low hypoid offset vs anything else out there were all selling points for me. My rear pinion with an M220 will be .75" higher vs my current 8.8, my TJ is my DD and my rear DC driveshaft operates at 21-22*, so it lives for about a year before the DC joint is absolutely worn out.

I was lucky to snag the old currie aluminum knuckles for $300 for the pair, so definitely gonna use those and make the rear m220 full float to have 99-04 UB on all corners. It's also a stock wheelbase TJ with an emphasis on up travel, so I didn't want to deal with shoving a D60 center between the frame and the motor at full bump. I removed the tubes from my front m210 center and will be pressing in some slugs, then returning to 3.5" axle tubes.

Not really planning on more than 35s, so I don't need the massive centers, but I want the 99-04 outers for longevity since I do 10-15k miles a year. And 45* steering.

Wanted to possibly use the factory lockers, but the cross pin design needs to be addressed and there's not much meat left to EDM to the side gears to 35 spline, plus I got quoted $600 for the EDM work. Cross pin wouldn't be too bad to upgrade, but I also don't like the super small thrust bearing washer on one of the side gears, seems like a lot less surface area vs a normal thrust bearing in any other diff and I don't want to be rebuilding a diff because of a stupid thrust bearing after 20-50k miles. Pretty sure I have pics of all that in my other thread. I'm just gonna shell out for the 35 spline ARB's
 
JL guys are ******ed on prices. "It's repairable, make me an offer, if it wasn't broken it would be $8,000, that's what replacements cost"

I did pick up an M220 out of a newer Colorado I think. $200, factory locker and shafts, just with some noisy gears. Like 66" wide I think and has 6x5.5 so it'll be a perfect swap into the rear of my J10 once I throw some 4.56s in it
 
Before I forget again, I found this when looking for pictures for what exhaust I put under the Rubicant..., this is the Chinesium JK Rubicon front axle I bought (behind it is an axle I got from Baseline 4x4 from a 2017 Recon). In storage have a Recon front housing I bought when Americas Most Wanted 4x4 was clearancing them out and maybe I'll try to dig it out and compare. It is buried in the back of a "temporary" shed so no promises.

Anyway, as far as I can tell it matches the factory axle in the front of my 2014 JKURubicant. I have everything I need to put it together including RCVs, but I now have my eyes set on 2025+ JTR axles because I'm tired of my tires rubbing the frame.

It seems like stock jl stock axles would have suited you well and would be near indestructible on a tj with 35s. But to each there own and if you just wanted a project then you got one lol
 
The aluminum knuckles are obviously hard to beat wieght wise. I guess would probably be fine in a light ass rig?

Yes, there are thousands of them out there running 37s under JLs/JTs, they would be fine in a lightweight rig.

I just pulled a set of M210/M220s out of a JT a few weeks ago and will be pulling a set out of a JL this week. Less than 5K miles on them. Both wide track, JL rear has a locker. Both missing brakes and the tapered ball joint camber sleeves.
I can check with the boss to see what he wants for a set.


When I was shopping, I saw several sets of Rubicon take outs in the $3,500-$4,500 range from people upgrading to 1 tons.

$4,500 to 6K is the price we usually see Rubicon M210/M220 sets go for.
$2,500 to 4,500 for non-Rubi axles.
 
JR4X what's your thought on 3rds for the axles you're bench racing in this thread? I'm assuming LP's to keep with the theme, what do you consider the limit for LP front 3rds tire size/rig weight? You've already stated your rig is going to be very light, so I assume LP is no issue strength wise.
 
Idk what specific trim model it's out of but I went and checked out an M220 out of a jeep yesterday. Has shafts, probably stock, calipers, ARB diff cover and a 32 spline ARB in it. Not exactly sure what ratio, possibly 3.73. They're asking $850, I can send a link if anyone's interested. I passed on it, just was checking if it was the 35 spline ARB by chance.

Edit: located in Lebanon, OR 97355

Probably would have, but I did bend my front TJ 44 jumping it at the dunes lol. I just wanted to build something and never have to worry about it. Some gun drilled shafts would be the cherry on top for me lol

Cheaper nodular low pinions F&R. Has to be low pinion to get the ratio I want. Cheap eBay gears. Lunch box locker front spool rear. Truck thirds will be plenty strong enough for this.

If it actually happens I might just order two crate 3rds built and ready to drop in from quick performance or speedway. But I’m a diff builder. Buying them pre assembled is weird.

This is what has me knowing these are sold second choice to SD’s

Please do. Probably not interested due to price and travel distance. You’re a long way from home homie!
$4,500 to 6K is the price we usually see Rubicon M210/M220 sets go for.
$2,500 to 4,500 for non-Rubi axles.
This what I’ve been seeing price wise since before the JL even existed yet. Those numbers are spot on.

Which is perplexing :confused: Dollars to strength that’s a terrible value. I have two 2011+ SD front 60’s and E locker Sterling 10.5’s that I paid $1,500 dollars for. For the math challenged that’s $750 a pair. I could slam gears in them and be in a bad ass set of axles for a Jeep under $2K ready to go. Then the axles they replaced in this scenario are going to sell for double that amount? I’ve thought about just buying and building a Jeep for this project but they are way bigger vehicles physically than I want.

meh, just a slight detour when you go race the big sky 200

I am actually looking at doing that. And because of my current 7 on 7 off schedule I have the days off post race for the detour
 
I haven't been able to comprehend what's propping up the price of these takeout JL axles, it's pretty insane. Even the 186mm (D30) prices are as if they were unobtanium. The most expensive axle prices I've ever seen by a long shot. But they seem plentiful and not particularly desirable outside of our uses? Or are there that many JL owners bending their axles on curbs lol

$4k+ freight for a used axle outta a wrecked rig? :laughing: Or am I missing something?

Guys love swapping these into older jeeps Xj cj yj tj as well as other smaller platforms just like they did with the JK axles. I found Mitchell on a fb page entirely dedicated to swapping jk and jl axles into other things. It isnt a new concept, it just isnt seem on the "hardcore" forums where "throw tons on it" is the typical answer.

90% of marketplace are crackhead sellers but there are deals to be had if you are patient. Ya there are morons selling busted FAD axles for thousands but there are also some giving them away. Retube the long side and set it up for a normal seal if it isnt already. Find a rear that the locker sensor was toast and the dealer replaced the whole housing and you have another budget freindly option

That really isnt too bad if someone wanted to run 5.38s IMO. The ultimate came with chromo axles. By the time you put a locker, gears and shafts in any axle you will close the gap there
