We keep blowing diffs.

[Guy]

Ok lets test this

Anyone who's got blown spider gear diff centres laying around have a good look see. See if there is a seized gear on a shaft.
I'll bet there is.

I have spun the tyres hard for loooong periods of time in suzukis for what seemed more like 15 minutes than 15 seconds ... so Zuk diffs are X100 times stronger than hilux diffs

[Red_Zook]

id say a quick easy fix would be to weld them,
puts the load over all the pins evenley.. well in my head anyways..
also just a hijack.. how big is a gq wag r&p?? 10iinch??

H233 - 9.1"
H260 - 10.2"
C200 - 8"

The ring gear diameter in mm is the model number as far as I am aware.

GQ wagon and coil cab are H233.
GQ tray leaf is H260
GU wagon is H260 by the sound of it.

I believe the weak point on the H233 is pinion shaft strength but I could be wrong. H260's seem to be strong everywhere.

Steve was abit hit and miss which GU got the H260. Large number of ZD30's had them. But can be found in other models. But generally, the H233 is the most common. Which is the same as a GQ but somewhere around 70mm wider.

[cruiserkid]

Would not having enought slip joint movement do it?.
Because to me it seems that the tail shaft needs to be shortened.
Still working through the options at this stage.
We are looking a some 75 series diffs with air lockers in them, they might be the go I think.

Mates had H260 was a 4.5

[Tapage]

An old mechanic told me that spider gears breaking is caused by excessive wheel spin on one wheel.

Bingo !!! tha's it ..

Add to this the point already posted that we don't know about those spider gears history .. and add the 350 power ...

I add a ARB or Detroit locker as already posted also to solve this issue .. ( maybe driving style start blowing other thing )

So can a GQ centre from a H233 bolt straight into a GU H233 housing?

are the side gear splines the same? I don't know, just asking the q

[bazzle]

All coil rear the same with 233's

[Cheezy4x4]

Weak piont of a H260 is the long pinion. I have broken one and Pete Antinac has also.

[Cheezy4x4]

Toyota, Nissan and ford are all around the same size but sit the crown wheels and pinions side by side. The Ford and Nissan crownwheels are alot thicker than the toyota and so are the teeth of the gears. The Ford 9 has a much beefier pinion than the other two also. For cost and ease of your prob I would go a reco toyota with a ARB locker and stop doing single wheeler line lockers (come on its a 350 we know he does). If you want all out tuff go the big $$$ built Ford 9. I have run 1280hp through a built 9 with no probs but it cost around $5K to build.

someons gonna be upset about posting this but here ya go,
this will fox your centre issues

that is turbo4t off this board selling them.

We have been just boltiing in new centres.
The first one was the original one that was in the vehicle when he bought it.
The second one was a spare I had laying around out of a BJ70.
And the one we blew one the weekend is out of the front of a HJ60.

I dont know a lot about the internals of diffs, but from what I have been told it is the cross pin that keeps breaking which is then destroying the spider gears etc.
If that makes any sense to you.

Part of the problem could also be that none of the above sound like "new" centres. They sound like diff parts of unknown history that have been lying around in the shed for who knows how long after being fitted to a car with unknown use.


Dumbdunce and Gwagensteve, could this be a technical match made in heaven?

i having a wager on DD.

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.
