Rear axle upgrade?
 
New guy here, starting a new build. Have a 96 Hardbody 2wd. Was wondering what rear axle upgrade is the most popular? I see folks have done the Dana 44, has anyone done a Ford 8.8Ē Explorer swap? Strong axle and disc brakes all in one. Iíve read the rear axle in the Hardbody is 59Ē wide and the Explorer 8.8Ē is 59.75Ē. Thoughts?

Planning to do an engine swap too? To what?

Axle swaps are not real common around here. Some of the pathfinders had rear disk. I think the izuzu axles (Rodeo??) Are a little 44 that fits.



The OEM axle is way stronger than people expect. The H233 is a monster. 233mm ring gear. A guy that was on here had a supercharged D21 V6 on 37" tires with a H233 in the rear. Kept blowing out the front wagoneer axles. The rear never had any issues. The Flaming Marshmallow has a PS4. I think he still has a stock 4cyl rear axle from the late 80s. I'm running a mild VG33, so is JP, on stock H233 axles.

Thanks, thatís really kinda what I needed to know. I built a 68 Bronco from the ground up, but I really donít know anything about these trucks other than they are sturdy and a good project truck. Is there a rear disc brake conversion kit? I HATE working on drum brakesÖ lol. Iíll have to check what axle I have. Is it stamped somewhere? Or did all that year come with the same?

Was thinking of either the small 240sx turbo kit or swap to the V6. Iíd be happy with 275/300 HP.

Honda Passport/Isuzu Rodeo rear ends should swap over pretty easy. I havent done it myself, but have read several places, that it is a direct bolt on. The break lines may or may not need some modification.

Being that you're a 2wd, IMO it would be easier to find a D44 from a Rodeo with the gear ratio you want than finding a 2wd V6 HB with a H233 axle.

H233b axles with discs (pathys only) can be found but the ratio is going to be 4.1, 4.3, or 4.6:1 usually the 4.3:1.

As far as the disc swap, it is really simple, hooking up the parking brake may require some fabrication though.

www.nissannut.com will cover the swap.

I have a 2wd V6 HG37 H233b but I’m in alabama.

Thanks anyway Brother!! :thumb:

What are you trying to do?

In stock form, there is no reason to upgrade the rear axle, as it is strong enough.

If you want disc brakes...put in a Nissan Axle. IMHO, drums work just fine in the rear.

Reserector 09-15-2021 05:38 PM

dvdswan nailed it.

I have a HG46 with limited slip diff from a 94 Pathfinder SE. Disc brakes. It is currently behind a 5.3L Chevy v8. The Nissan axles are stronger than any 8.8 IMHO. I cut off the coil buckets and link mounts and welded spring perches on mine in order to swap the complete axle from a C200


You could get away with swapping the guts into your H233B housing, though. There's just the parking brake thing to work around. The truck is side pull and the cable won't connect to the drum in hat setup that the Pathy uses. Pathy is center pull.


I had mine rigged up, but mud kept killing my park brakes, so I eventually just gutted them.

Since I am a newbie, this is what I needed to know. It definitely sounds like the stock axle will stand up to a moderate addition of HP

Could you please elaborate on this? Are you referring to swapping the stock drum axle shafts with the disc brake axle shafts out of the Pathfinder?

This definitely sounds like the way to go in order to get disc brakes and not have the parking brake issue.

I have some fab experience as I built a 68 Bronco from the ground up, so I am familiar with welding on spring perches.

Here is where my newbieness shows. Instead of cutting off the coil buckets and link mounts, can you convert the rear to link and coilovers? Or would you not want to do that?

How do I know what rear end is in my truck? 2.4L Z24 with a 4 speed manual.

Look at your door sticker or engine compartment pass. side fender wall, there will be a plate riveted to it. It will state your axle code. i.e. HG46 is a H233b with 4.63:1 ratio. CA43 is a C200 with a 4.325:1 ratio. and HF37 is a H190 with a 3.7:1 ratio.

https://www.nissan4wheelers.com/topi...xles-do-i-have

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.

PoBoi850 09-17-2021 01:44 PM

Thanks. My Door Door sticker is NO BUENO. All of the print has faded out of existence. I'll have to check the fender wall. Hopefully it's still there. The truck had PS damage that had been repaired before I got it.

Deerhurst 09-17-2021 04:46 PM

Older trucks have that info on the inner fender of the engine bay.

PoBoi850 09-17-2021 05:15 PM

I've looked all over the engine bay for it. No luck. Probably the H190. Non removable cover on a 2wd

Deerhurst 09-17-2021 06:56 PM

Usually top left under the passenger side corner. Metal tag.

Apologies if I'm highjacking this thread.
Here is my passenger fender. Can some one tell me where it "should" be. I think it came off a long time ago
Sorry it's a crappy pic

The photo is tiny. What is that box on the fender?

I can't make anything out in the picture but if you have a 2wd 4cyl base model almost guaranteed it's either an HF35 or HF37 axle.

PoBoi850 09-20-2021 12:32 PM

The black and blue boxes are relays.

Sure can. It's only steel. Make it do what you want it to do.

A D21 V6 2WD H233B makes for a good swap if you can find it. Right width, right perch width, higher gearing. I swapped out the H190 on my 98 Frontier with one, added WD21 discs, added LSD. Went from 3.7 to 3.9 gears, corrected with new speedo pinion. Spliced the OE parking brakes to the WD21 cable housings. Added WD22 sway bar.

Write-up here: https://www.clubfrontier.org/threads...brakes.367791/

I agree that the Nissan axles are stout, but I've busted spider gears in the H190 before. Did the swap because I hoard Nissan axle and differential parts.
