I asked other Nissanheads and they are not saying which is stronger. Probily don't know since we don't have these diffs in the US of A.
This is for MK's btw....
1986/1987 H233 full floater
or
1980/1987 H260
So which is it? Or is one stronger than the other in certain areas? Such as the H233 FF having stronger axles and the H260 having a stronger r&p? Could you make the H260 a full floater?
Whatcha think??
Also...have you ever seen a H233 FF? Are they as rare as I think they are....??
I haven't seen a H233 full floater, but i would say that the h260 would be a stronger unit, definately stronger than the standard h233, bigger axles ring and pinion.
There are no stupid questions, but there are a LOT of inquisitive idiots
yea the H260 is all around larger. But a full floating axle the weight of the truck sits on the hub not the axle. The plain jane H260 is not a full floater thus the truck's weight sits on the axle. H233 ff this will not be the case which makes me think overall the smaller H233 is at the least less likely to brake an axle. I am thinking the H260 is definately stronger in the r&p as a ff won't affect the diff center, only the axles.
Yea maybe but i would have thought that even without a full floater setup most of the weight of the truck would go no further than the outer wheel bearings, where it would be distrubuted to the housing.
I read somewhere that a h260 has 40mm axles I'm not sure how big the h233ff axles are. And most of the broken axles ive heard of have broken near the spline, not between the flange and outer bearing.
i reckon they'd both be pretty strong, guess it just depends how easy they are to get and get parts for. - What are u planning on doing that would overload a h260 anyway....

My opinion is that H260 is stronger.
But I´m f*** up that I cant get any locks to H260/H233, at least any reasonoble price, locks to front+rear = about 2500 euros,WHICH IS QUITE MUCH, I can get Volvos portal axles for that price and they sure are locker axles.
But I think I´m gonna use Toyota HJ61 original locker axles,full floater at rear,they cost only 500 euros.
BTW. heres few pictures and videos how to break H260
My mistake, I wrecked it with welded rear lock and snowchains + increased power by turbo. *CLICK HERE*
Yes h260 is stronger. I believe that as usual Nissan overbuilt , with this axles as the spllines are 1.5 inches and count 37. The ring gear is about the size of a d70, which is the axle on the Ford Super Duty (a much larger, powerful vehicle).
axle diameter and ring gear diameter is not the answer. The material will make a big difference, no good having 40 spline axles made from cheese.
also design will also be important, pinion gear to crownwheel contact area and strength of teeth are more important than diameter.
also strength of the case, to resist distortion, is important.
eg: the 9" ford diff has 3 bearings on the pinion shaft, to resist deflection (a big cause of breakage) and has a larger tooth and bigger contact patch than a D60. So they are actually stronger in the centre than a D60, and only need to be converted to Full Floater to fully supercede the D60 for strength, even though the numbers (sizes etc) are smaller
Front diffs by design are full floaters, for interests sake. That is why they can survive a little more punishment than the semi floater rears (in the axle department, anyway)
Trucks run full float diffs, and you can buy kits to convert 9" Ford diffs to full float quite cheaply.
ok, it seems appropriate to put this question in here seeing as were talking about H260's.
I just bought a H260 from a 4.8 Patrol 2003 model. I currently have a full float rear leaf on my ute, im going to a coil swap. Both the rear diffs i have a 4.3 gears. The coily diff looks like it may have had the handbrake on it?? Is this right?
what i think is the handbrake is circled in red???

Semi float diffs have the wheel flange as part of the axle, supported by bearings in the axle housing. The axle is retained by the bearing. The axle itself carries the weight of the vehicle, and takes the load when you jump, get wheelspin, then traction, carry a load etc etc.
As the axle is retained by the bearing, if it breaks between the bearing and the wheel flange, the wheel parts company from the car.
Full floater diffs have the wheel, brakes and weight of the car supported by 2 bearings on the end of the diff housing. thru the middle of it all is the axle, and all the axle does is turn the wheel. In fact, you can remove the axle from the car, without even pulling the wheel off, and still drive it.
but i would have thought that even without a full floater setup most of the weight of the truck would go no further than the outer wheel bearings, where it would be distrubuted to the housing.
I'm not sure how big the h233ff axles are. And most of the broken axles ive heard of have broken near the spline, not between the flange and outer bearing.
