This is all the axle codes, along with what the code in the door jamb means, and their ratios. this chart is up to 2004 also some info on swapping to different ratios and swapping open to lsd.

What Axle Do I Have?

The axle code is located on the door jamb sticker on Nissans. If it's not there, there are visual ways of determining what you have. On some older trucks it's on a plate in the engine bay above the fender well on the passenger side.

HF35 - H190 axle found in weenie 2wd Hardbodies.
HF37 - H190 axle found in weenie 2wd Frontiers
HF41 - H190 axle found in one 1996 HArdbody with KA24E and Auto trans.

CA41 - Found on 720's - This is a C200/R180 combo with 4.11 gearing. Some 720's have the smaller H190 rear end that's identified by not having a removable rear diff cover. R180 front ends in 720's are different than the Hardbody and Frontier versions, as the diff is nearly centered. 720's use unequal length halfshafts and are not interchangeable. All 1986.5+ halfshafts are interchangeable left to right.
CA43 - found on 720's and Hardbodies. C200 rear / R180 front, 4.375:1 gearing
CA46 - found on Hardbodies and 4 banger Frontiers - C200 rear / R180 front, 4.625:1 gears
CA45 - found in 2003+ Frontier 4x4's. This is a C200/R180 combination with a new gear ratio - 4.5something:1 The C200 was upgraded to 31 splines on this model from the previous 29 spline unit.

HG43 - Found on Pathfinders, V6 Hardbodies, and a few '99 Frontiers - H233B rear / R200 front, 4.375:1 gearing. On the 2000+ 33 spline axles, the HG43 has a 4.363 ratio, however this is not a common axle code on the later models.
HG46 - found on auto equipped pathfinders, 96-97 hardody 4 bangers, many Xterras and Frontiers. This one has some variation. Pre-2000 versions are the H233B axle with 4.625:1 gearing (31 spline axles). 2000+ is the H233B axle with 4.636:1 gearing (33 spline axles). Typically comes with an R200 front axle, with the exception being in the '96-97 Hardbody pickups - those had an H233B / R180 combination. Axle shafts in the H233B were 31 spline up to about 2000, where they switched to 33 spline shafts. All Xterras and R50 Pathfinders received the 33 spline axles. In Frontiers, it can be a crapshoot if you have a '99-'00 model, though it is believed that the switchover was at or near 2/00 production date.
HG49 - found in mid year 2001+ Frontiers and Xterras. H233B / R200 combo with 4.90:1 gears.

I've learned recently from posts in NICOClub that there were some Hardbody 2wd's that appear to carry the C200 axle, but I've never actually seen one. If you have one, it's a rare bird. I'd love for anyone to post up their information and describe the year and model (I4, V6, XE, SE, etc.) of the truck that carries the C200 rear in the back of a 2wd so I can update my FAQ on my website.

Locker Selection:
ARB lockers are available for the older 30 spline C200's and all H233b's. They're also avaialble for the R200 front, however no traction device is out there for the R180.
Calmini LSD's will work in an R200 front. (A Calmini LSD is a slightly modified '87-89 Turbo 300ZX LSD)
Lockrights will only work in the older 31 spline H233B.
Detroit used to make a locker for the older 31 spline H233B, but those are getting scarce.
Up to 4.875:1 gearing is available for C200's and R180's. Up to 5.143 gearing can be had for H233B's and R200's. AC and SLR are the two companies offering gears, or you may be able to get them through Nismo.

Let's say you don't have the doorjamb sticker.
H190 - small 3rd member type axle found in 2wd's only (excluding Desert Runners, Xterras, pathfinders)
C200 - removable rear diff cover, 8 bolts. Found in all Nissans (yes, even a few early 2wd Pathfinders)
H233B - large 3rd member type axle found in most V6 and a few 4 banger 4x4's, Desert Runners, and 2wd Pathy's and 2wd Xterra V6's.

Other notes:
The H233B 3rd member changed from 9 bolts to 11 studs to hold it to the housing beginning with the 1990 models. Somewhere along this time (maybe around 6/89, the bolts holding the ring gear to the carrier changed from 10mm to 12mm, making a difference in replacement gear sets.

What do the numbers mean?
The number in the axle model indicates the size of the ring gear in mm.
R180 - 180mm ring gear
H190 - 190mm ring gear
C200 / R200 - 200mm ring gear
H233B - 233mm ring gear (yes, that's about 9.25"!)

How do I figure out my gear ratio?
Put a jack under the diff and get both wheels under the ground. Draw a chalk line on the tires where they would contact the ground. Rotate BOTH tires by hand at the same speed one exact revolution while counting revolutions of he driveshaft. Just under 4 1/2 turns will indicate the 4.375:1 gears. Just a bit over 4 1/2 turns would indicate 4.625:1 or 4.636:1 gearing. If you have a late model, just a tick under 5 turns of the DS would indicate 4.90 gears.

LSD or open?
If you lost the sticker, get that jack back under the diff. Turn a wheel with the truck in neutral. If the other wheel spins in the opposite direction, you have an open diff. If it spins in the same direction, you likely have some sort of traction device - probably an LSD.

Additional Contributions:
Contribued by OnlyOneDR on N4W:
Tractions aids can be found for the R180 in the 720, Nismo, Quaife, Kaaz, and Cusco sell LSDs, mostly because the R180 was under the earlier Zs and newer Subarus. Not sure if you can swap the bolt retainer in from an open R180A carrier to get it to bolt into an HB or Frontier axle. I did that trick to get my 300ZX lsd into my R200A.
The HB and Frontier front axles are "A" axles, (e.g. R200A, R180A). The A designates an offset carrier. The R200/R180 are different because it is centered and does not have axle tubes on either side.

Contributed by OffroadX of N4W, AC, and XOC notoriety:
I'm not sure that the A in R200A etc. indicates an offset diff, from what I gather, it indicates a short-pinion diff. The Patrol uses offset front (and even rear) H233 diffs, but they're not designated H233A. I have seen in the Nismo catalog that the R180A was developed with a shorter pinion (by 120mm) to reduce driveline angles vs. the regular R180.

The R180A axle designation is RB
The R200A axle designation is RC
C200 and R200A gears ARE INTERCHANGEABLE. Yes, the same part numbers are used for the same ratios in the Nismo catalog for both diffs.

Best I can tell, 10mm ring gear bolts were phased out of the H233B diffs 6/86.

There are 5.571 and 5.875 gears available from Nissan/Nismo for the H233B

Regarding the H233B, the ONLY difference in Nismo 5.14 gears are at the 1990 model year. There were originally only gears for pre-90 diffs. AC sold a modified version of those for post-90 diffs, but a couple of years ago Nissan finally started making 5.14 gears for the 90+ diffs. 4.90 Xterra gears will go into any 90+ diff too

Thats awesome. Now someone needs to find some info for the Toyota axles. Im gonna do the rear swap and want to see all my options for LDSs and ratios. Like what to run with a 31" tall tire and keep my drivability with a 5 speed...

burrsg101
10-25-2008, 02:07 AM
the ratio toyota used when the trucks came stock with 31s was 4.87 for auto trannies and 4.56 for manual. see my other post to decode the different axles

Low F350
10-25-2008, 02:42 AM
So if I have the 4.625 gears in my frontier how will the 4.87 or the 4.56 gears affect my truck?

burrsg101
10-25-2008, 03:09 AM
im not sure hwo your truck drives right now or what size tire or anything like that that your running, but if you went with the 4.87 youd gain a little acceleration over your stock gearing, but you'll also lose top end and when cruising on like the highway your rpm will be higher. if your putting bigger than stock tires on it would be a good idea to go with the 4.87 because putting bigger tires on is kind of like going with a lower gearing such as like a 4.40(random example) where youd lose some acceleration but the highway cruising would be at lower rpm. its up to you which way youd like it, you could leave it stock with bigger tires (i assume your putting bigger on) and youd lose some acceleration but youd cruise a little better, or you can go with the slightly higher gearing and go back to how it was stock, or go even higher and gain even more acceleration than stock, but youd lose top end again and cruise at higher engine speeds. keep in mind here that nissan trannies are also geared a little different from yota trannies. my pathy is at its stock gearing with undersized tires and its annoying as hell because i cruise the freeway at a rediculously high rpm. thats getting fixed though soon when i swap my z subframe in :) hope this helped

Low F350
10-25-2008, 02:33 PM
Yeah that helps a lot. Right now the truck is on 18s with a 40 series tire. The new wheels will be a good bit larger. So I guess the 4.87 will work perfect for me. Thanks for the info.

I've seen this list on many forums. It doesn't mention the HG39 found in my 93 2wd w/ VG30 engine.

There aren't any drop-in LSD options for this rearend. I want LSD, which factory LSD rearend should I swap?

burrsg101
02-18-2009, 06:38 PM
the HG39 just stands for the ratio it has. its a 3.9:1. Its still the same axle though. Also hardbodies had an option for an lsd rear end, you just have to find one in a junk yard. try car-part.com. Also 4x4 parts has a clutch type lsd for like $550. https://www.4x4parts.com/catalog/product_info.php?cPath=165_303&products_id=295

ok guys i have a 87 2wd hardbody with a vg30 and a 5 speed im a little ways from the truck so im just asking this, a buddy has a lsd thirdmember from a 95 4x4 pathy he is doing to throw it away if i dont want it today, so what are the chances of this fitting in my truck??

nismopu
02-27-2009, 09:59 PM
It will work in your truck the pathy and the v6 2wd use the same h233b rear axle. If you read above you will see the only difference will be the ring gear bolt size so drill them out and tap them on your carrier for your ring gear from a machine shop. Dont do it with a hand drill! peace.

burrsg101 i have a hb with a c200 ( i think)

its an lsd and it has the 8 bolts with a removable back caseing.

my d21 is a king cab also but its nothing special.. z24s p/s a/c.. could it have been a factory option? or could it be more common in the aussie ones?

I sold my old rear that was a HF35 out of my 89 King Cab. The guy I sold it to put it in his 97 King cab but he had an LT1 vette motor. He was trying to find another 4x4 rear with an LSD but couldnt find one. So he bought mine to get by with. Needless to say he spun the axle bearings in a month with the V-8.
I have a C200 out of a 96 King cab with an auto trans. It has the HF39 axle ratio. 3.90 is the exact number. Cant wait to put this in my truck now that I have the 18" Titans on it.

now are these axles any longer or shorter???? i seem to remember my buddy had a hb with a v6 and it had the bigger axle because it had a differencial cover. And his axle always seemed really wide because he had to flair the shit ouy of his bed just on 17 eskies

I just put a h233b rear in my 93hb and it fits perfectly, axle code is HG46 came out of a 97 4x4. The only difficulty with this swap is you have to shorten the Drive Shaft, The widths are the same.

I take it you have an auto tranny with those gear ratios?
How many miles on the truck? Rear ends dont last forever. It could have been its time to go or the axle didnt get serviced enough over the course of its life.

The 5sp comes with the HF37.... went to the JY and found a 720 auto with a HF39.

Not sure on the milage of the rear end as it was replaced some time ago with the exact same thing. I've put well over 100K miles. My engine doesn't qualify as stock anymore so that had more to do with it than anything else.

I'll see how long the HF39 3rd member holds up. I bolted it up to my axle and will be trying it out this week.

I saw a new ratio or axle code I havent seen before on an HB. It was a '97 reg cab, KA24E motor, Auto trans. With the HF41 axle code on the door. I thought that was unusual. But it would roll nice with the some Titans on it.

Hi guys- adding to the never-ending rear end threads!

I recently pulled a junkyard H233b from a 1988 Pathfinder V6 4x4 auto.
I'm not sure of the ratio, but 1 rotation of the wheel gets me 4 5/8 rotations on the driveshaft. Maybe 4.625 or 4.636?
http://i205.photobucket.com/albums/bb287/hessianben/IMG_1637.jpg

My question is: Is it possible to find 3:90 gears for the H233b rear end??

My '02 Frontier (broken, sad, waiting for a new rear end...) came with a c200 rear with 3:9:1 gears. http://i205.photobucket.com/albums/bb287/hessianben/1_MG_8650.jpg

I can't run the shorter gearing from the pathfinder or I'll be turning 6000rpm on the freeway!

Are there any pathfinders or H233 hardbodies that came with gears closer to 3:9?

Thanks guys!!

I picked up a H233B from a Pathfinder SE today from pull-a-part. $119 bucks without a core, and complete rotor to rotor. If your in the Oklahoma City area and want one, I saw at least 3 others there, all complete. Bring 22mm wrenches for the link bars (I forgot mine and had to go get'em) and get there early and beat the heat.

07-27-2011, 05:25 AM
Looking at my pathy axle earlier I noticed that there is a plug at the yoke on the 3rd member. Does anybody know what thats for? I assume that its something that has to do with the 4wd? I don't think that its a speed sensor since those are normally on the tranny, but I could be wrong its happened before. ha. The weenie axle in my 2wd HB doesn't have it, so again, 4wd? like a locker? I'm not familier with 4wd stuff, not my bag.

So, I'm seeing a lot of rear end swaps. I have a 97 reg cab 2wd HB with the ka24e 5speed. Pretty sure its got the h190 in it, but I'll check when I get home tonight. I want some more traction, and I want to slide it really bad. I'm tempted to pull the diff and weld the spiders. I'll get sideways and hook up straight line pretty well. However I plan on driving the truck this winter, so I'm looking for lsd instead. Is it possible to just swap diffs? Or will a whole rear end need to be swapped?

Hope I get some help here.

I got a 2004 KA24DE Frontier XE with Automatic trans. It say CA46 axles.

It has a C200 diff, and I know it comes with the 4.625 FD. ( 5 Speed truck is 3.90 FD )

I am in the process of putting a turbo on the truck. It should get 280-320 WHP when done.

I want to put a LSD unit on the truck. What are my options?

Does the R200 LSD unit bolt right up.

The C200 splines come 31 and 29. Which one do I have?

hessianben
09-20-2011, 09:04 PM
you are going to have a tough/expensive time finding something that will bolt in.

your money will go farther by getting an h233b rear axle/housing/assembly from a v6 hardbody and finding an lsd from an SE V6 pathfinder and you can harvest the discs from the pathy too!!

although it may be easier to just get the whole pathy rear assembly with discs- except you will have to cut off all the suspension brackets. with the hardbody, it will bolt straight up- you WILL have to have a custom driveshaft made- using the V6 rear d/s flange. i had the driveshaft shop put a stub/slip assembly in, so i can switch rear ends without having to make another driveshaft.

The SE version of the v6 pathfinders have LSD and discs, and most come with either 4:6 or 4:3 gearing. annnnd they are way stronger than our C200 units.

look at my build thread for some ispiration;

thing that's tough about that, is that you've gotta shell out the $580 or whatever first, before you can even start working it out and seeing what will and won't fit.

if you switch over to the h233b rear, all you gotta do is weld on some spring perches- AND there's an ENDLESS supply of pathy's in the junkyards- half off days you'll be drum-to-drum for less than $300 ! ANNNND you can get your rear discs going!

Andreas Miko

Ok here is what I have done today.

I have gone out to the junkyard and may have found an easy solution to my problem, which is getting an LSD unit with a lower numerical gear in my frontier automatic that comes with a 4.6 FD The 2000-2004 Xterra's have have the larger diff, they appear to have the same wheel base as the frontier and the xterra's run leaf springs so there should be no cutting, grinding and welding., or very little.

The Xterra's come with drum brakes so the complete affair should be bolt up. I will be measuring an Xterra from drum to drum and leaf spring seat to leaf spring seat on Sat-Sun to make sure my findings are 100% correct.

2000-2001 Nissan Xterra have the larger H233 diff.

6 cyl, 4x2, locking, 4.363 ratio (235/70R15 tires)
6 cyl, 4x2, locking, 4.636 ratio (265/70R15 tires)
6 cyl, 4x4, locking, 4.636 ratio (265/70R15 tires)
6 cyl, 4x4, locking, 4.363 ratio (235/70R15 tires)

2002-2004 Nissan Xterra have the larger H233 diff

6 cyl, 4x4, locking, 4.636 ratio
6 cyl, 4x4, locking, 4.9 ratio
6 cyl, 4x2, locking, 4.636 ratio, supercharged opt
6 cyl, 4x2, locking, 4.636 ratio, w/o supercharged opt
6 cyl, 4x2, locking, 4.9 ratio

I am getting happy.

Nice! keep in mind though, that some of the later rear ends came with viscous style lsd's not the clutch style, but better than open diff! i don't have the info on which ones though...

I am not building a race truck or a drift truck. I just want something that spins both wheels and most xterra owners are women so the diffs and LSD unit should be fine.

The Xterra tread-track is 59 inches

The frontier K24DE tread-track is 55 inches

The Frontier V6 tread-track is 59 inches

I work at a machine shop, so the welding and cutting is not probelm.

I am going to go with the Xterra unit and shorten each end 1 inch for a total length of 57 inches. Then run 1 inch hubcentric spacers up front.

I will have to shorten the axles one inch and respline them. Worst case I will have to have some shafts made for $250 for the pair.

I am going to stay with the drum brakes because everything shoul bolt up they are alot larger on the Xterra vs the Frontier.

you may not even mind the wider rear end. i run aluminum adapter/spacers with some wheels just to fill out the fender gaps, so you could run spacers in the front and have a wider stance overall.

Andreas Miko

Well I dont mind the wider rear end but the 59 inches is to long.

Stock is 55, if I take an inch off of 1 inch each side the tread will be 57 inches and that will put the tires which are 18x8 23mm offset flush with the fenders right now. So all I would have to run is 1 inch hubcentric spacers up front. If I ran the 59 tread which is the same as the the V6 trucks, I would have to get Desert Runner flares front and back and then I would have to put on 2 inch spacers up front. The desert runner rims and tires seem to stick out a little past the flares from factory.

If anyone knows the axle spline count.

I have axle code CA46. It is on a 2004 KA24DE Automatic Frontier.

From the information posted this should be a 29 spline axle, but I am just trying to confirm this.

I've got an HF41 in my 97 Hardbody. I'm thinking about looking for an HG46 or HG49 because the ratio would work better with my tire size. Other than welding the leaf spring mounts onto the underside of the new axle and getting a new proportioning valve for the disc brakes, would there be any other mods required? Would my stock driveshaft bolt up? Do they all have roughly the same track width?

Thanks in advance.

i have a 97 hb 4x4 and i think it has the r180a like i read in older post. what are upgrade options for this? other than a SAS swap.

if you are looking for a stronger axle for IFS, the R200 from a V6 pathy or HB will bolt in, don't remember if the inner 1/2 axle shaft needed to be swapped as well though. there are a few offroad companies that serve nissan needs.

i just brought my truck to a local mech shop and they said the driverside boot seal on the axle shaft was leaking the transfer case was bone dry of fluid and they there is leaking coming from somewhere on the transmission. OMG i dont know the cheapest route for all this.

dvdswan
11-22-2011, 10:20 PM
I was meaning the inner halves that bolt to the stub shafts in the diff. they could be different don't know for sure though. you could do a lot of the stuff yourself. ie, replace the axle boot, fill the t/case and find/fix the leak on the tranny.

from your name it looks like you're in the AF, they usually have some sort of auto hobby shop on base to help/guidance in repair your vehicle.

yes i am in the air force and that is where i found the leaks the first time was the auto hobby shop lol...you ex military? you have a sweet nissan. looks like alot of work. i had a 2wd 95 hardbody in high school that was lowered a inch on 15x10s and low profiles. i loved that truck. so for the past 2 years i have been looking for a cheap 4x4 regular cab hardbody and found one. but should have looked at all the underneath stuff. didnt know it was going to be this much work. im ordering the calmini 3 inch lift next month and i already have the tires and wheels. just want to start doing some offroading and scared all the leaks it might break down

for it to be a 1 ton rear end it will be a full floating axle.

Ok well I guess it didn't upload....looked like it did on my brother in laws comp...mine is down until the new charger comes in....but check my albums under bone yard finds...wondering if I could change out the pumpkin for the lsd and disc brakes out of a pathy I found that I can't pull the rear end out of cause they put the lifts pinned under it...

Anyone know if you can swap in the lsd from a 95 pathy into a hg43 axle housing from a 94 or 89 hardbody??

look at the axle code of the vehicle you want to swap it into. if it has HGXX, then yes, if its CAXX or HFXX then no.

Yep that was mine too. Can someone add it to the list?

ALSO


UPDATE: I HAVE FOUND A UNICORN!!!@&!!!

I found a kingcab d21 4x4 vg30i with a 5speed at the junkyard....
And the axle code was ...... HG....37!!!!!
3:7 gears FTW!!!! It's an open diff but the gears should plunk right on to my LSD H233b carrier!! no more 4k rpm at 65mph! ;)

i have an HG37 too and im at a little less than 3k rpm at 65. mines in a 2wd VG30 powered truck... weird. mine must be rare? lol

on this list it has a CA43 listed for a 720 or hardbody. My axle code in my jam says CA43 and i have a 2000 frontier. will it be the same gear ratio. im wantin to swap out my rear end for a toyota one. but i dont know what the gear ratio is on it

My 98 frontier has a ca43 axle code. And its a 2wd auto. I thought that code was for 4wd?

wonderboy
03-17-2013, 10:22 PM
Im going to bump this up in hopes of a answer.
My axle code is HF37, from what Ive gathered its a 3.54(something like that) for a stick, but I thought that Ive read that it was a 3.7 auto.
I have a auto so just tring to clarify what ratio is in mine. Id like to get a little bit higher ratio (3.9-4.0). If thats the ratio that I have.

10-28-2014, 06:03 PM
so what is the hg37?? if im not mistaken, my 1993 hardbody(reg cab)ka24 with auto trans has hg37 with an open diff. i dont see an hg37 in the op. would it be good for a casual drift truck?

Ghosty
10-29-2014, 01:09 PM
