Yes they have been broken, but it takes some unholy abuse to do so even with largish rubber. 36's or less they are very very durable, 37's plus you need to think about your driving a bit and not just go at it like a rapped ape.

breakages will become more common, as comp trucks start to use long arm style rear links which tend to "plant" the tyres more in hard launches, this coupled to the use of 'stickies' or comp spec tyres place huge loads on the axles. Nissans have very 'brittle' axles and they tend to snap far too common. The axles are huge and will take far more power than alove_mud wrote:Yes they have been broken, but it takes some unholy abuse to do so even with largish rubber. 36's or less they are very very durable, 37's plus you need to think about your driving a bit and not just go at it like a rapped ape.
H233, the housings can be shaved quite a lot and done properly can have the same if not slightly more clearance than a H233 housing.

They said they can shave off 23mm which is still 7mm short of the H233 diff housing.
So 7mm less clearence than a H233 diff but on the up side a heap more strength.
Cheers
7mm vs 50%+ increase in axle strength is a good deal IMO.segan1 wrote:A friend rang Cheezy Racing today about having the H260 diff housing shaved.1MadEngineer wrote:breakages will become more common, as comp trucks start to use long arm style rear links which tend to "plant" the tyres more in hard launches, this coupled to the use of 'stickies' or comp spec tyres place huge loads on the axles.

(we shave way more than most in our comp diffs, we plug weld hole and add new studs to get another 10mm+)

The really BIG rear diff from a leaf sprung GU is a cab-star.
Looks about twice the size of that of the H260.
And is a true full-floater.

but the bolting flange is huge, so at the bottom we actually cut ~5-8mm off the bottom of it and move the lowest holes apart ~20-25mm and use bolts instead of studs.

Ok, now Im confused.
The GU leaf sprung ute has this rear diff housing (which I thought was from a cab-star truck - full floater) that is massive in comparison to that of a 3 litre GU rear diff, which I thought was a H260 (3/4 full floater).
It (3 litre GU rear diff) being massive when compared to a H233.
So, what is the housing that is in the GU leaf ute?

the leaf and 3.0L centres are the same (except a different spline count for the axles i think), the axle size is the same but the leaf diff has flull floaters and the 3.0L is semi floating. leaf diffs and the 3.0L are 4.3 ratio however there is also a 4.2 ratio version but i dont know what they were factory fitted to.bushy555 wrote:>Some Cabstar trucks had a full floating version of the H260, but with

The Cabstar truck H260 diff center is exactly the same as a patrol H260 but with a 2 pinion center and 6.72 ratio. The axle shafts are 37 spline 1.5" at the diff end, but neck down a fair bit to pass through an oil seal located in the end of the stub axle. Even though the Cabstar version is full floating, the stub axle and hub are much bigger than the GU full floating version--presumably to cope with the extra weight as the truck has a 3ton payload capacity. The axle housing itself is also much narrower than a patrol housing.
Also slightly off topic, but worth mentioning, is that later versions of the Cabstar truck use the same transmission as the GQ, but with a cable shift and lower gearing. 5.72:1 first gear and slightly lower 2nd 3rd and 5th gears. This version of the transmission is an RS5R50A--RS meaning 'remote shift' i presume.

This is a shaved H260 -
This is a H260 axle beside a 12mm Rachet Ring Spanner -
H260 Centre -
H233 Centre -
This is a shaved H260 (Different to the one above) -
Hope that helps

WICKED you are a legend.
Now i need this done.
Im in Victoria, does anyone know where i can get a shaving job done like the top pic for maxium clearence.
Will prolly travell to NSW to have it done if i cant get it done here.
Cheers

Pretty sure they stopped fitting the big diff to the wagons in late 02 when they went to the GUIII.mickyd555 wrote:3L autos did and manual didnt or the other way round, im not sure.Micka wrote:I thought the H260 was in the 4.8L petrol Patrols and the leafy Utes only.

We had an '00 GU 3.0L Manual with the big diff. Seems to be no set pattern to which vehicles had the big rear diffs.
Just another random nissan parts bin thing.
