Axle Differential Codes and Ratios up to 2004

[jimmy726]

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 just blew my HF37 (37 tooth ring/10 tooth drive pinion) diff. Spider gears had too much play and eventually broke. The axles are 29 spline. Looking for options.

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.

It's hard to find Nissan/Datsun rear so I converted to 5 lug. Also more cheaper and different gear ratios to choose from.

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?


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.

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 think 4.38 is the lowest for the h233b,pathys as well from my experience,maybe im wrong though.
