GQ Front diff in 40-55series

Joined: 10 Nov 2002 Location: Sydney

1 Has any one fitted a front GQ diff into a 40 - 55 series cruiser and kept the leaf spring setup?

2 Will cruiser front axles fit into the Nissan center? Or are they a different spline count and diameter Question

Totaly different diffs. why would you use a Nissan diff in a toyota and want to use toyota axles?

Hang on why would you want to use a nissan diff at all?

Nissan diff is high pinion (like the 80 series) but was wondering if the center is stronger than the weak 80.

The high pinion will go part way to fixing a very bad driveline angle.

Nissan center - toy axles - 75 series cv & hubs brakes etc.
I have all the toy parts lying around.

Yeah far enough point and im not sure on this but i think the nissan front centre may be 30spline but prob a different pitch and axle size. I think if you real;y wanted this it would be way cheaper to just cut all the mounts off the nissan diff and use it complete because the CVs are a lot stonger than the Toy ones. Also can you match the ratios?
If it were me i would just use a pair of nissan diffs.

from TTC 2002, nissan front and rear diffs, with leaf springs,

toyota axles WONT go into the nissan centre, i dont think the nissan HP, is THAT much stronger than the toyota one, but as a bolt in you can get 4" of width or more, so best to go with a complete nissan axle, if this floats your boat, and is cheaper than 80 series!

especially for $$$, hybrid axles, seals, and so forth will cost heaps!!

. I can match the ratios 4.8

.thanks I`ve just checked the FJ 45 `Gadget` out in TTC 2002

.....AS I have all the Toy parts Ill probably just run the original diff housing with 9.5 inch center cut the balls of and replace with the larger 75 series balls & cvs etc.
Ill also rotate spring saddles and balls to fix the bad drive line angle.

75 series CVs are the same size as the 40 ones. And HZJ75 ones are only just larger but not worth the hassel. 80series are larger again but not by enough again to make the conversion worth while.

You can now buy strengthened CVs to suit your 40 localy up here in Brisbane that have a lifetime warrenty i beleive. They are available through Custom Off Road Engineering. Team C.O.R.E from TTC this year has been running them since before TTC and i dont beleive he has broken one yet. He snapped an axle at TTC in the front but did not hurt the CV.

I am running Longfields but they are imported from the states and are big $$$. C.O.R.E's i beleive are much cheaper and localy made.

dont want to push in but to run front and rear patrol diffs you will have to run patrol trnsfr case as they are reverse cut gears in the front diff where as in a landcruiser they are not so if you fit just the diffs then you will be driving towards each other .Also if you are after a set of super strong CVs to suit a landcruiser 40/60 series then i can put you onto a set with lifetime guantee

WTF they are reverse cut but not reverse rotation. They still turn the same way. There are plenty of rigs around running swaped in patrol diffs and still running the original transfer and there are also a lot of rigs running the patrol transfers with the original diffs.
80 series,FZJ75s and also bunderas run reverse cut gears in the front as well and they still run a standard rotation transfer case.

Tell us more about these CVs?

Not really that much of a bolt-in when you look at how much the springs have to be outboarded to clear the centre.. This is the front of gadgets truck.

Hilux and Cruiser 40's, 50"s, 60's & 70's up to 1990 had the same CV's. The later 70's had a reinforcing rib around the out side edge of the outer but the inner bits are vertually the same. I would agree that the strengthed CV's would be better than the standards but i have had the Inner spider split on several occasions and spin on the inner axle splines. The other problemns when you give them a hard time with this size stuff is the king pin bearings are small, too close together also the swivel ball collaspes the bearings become loose and the CV's are a bitch to get out. With the 80 series stuff the CV's would be easy 3 time stronger, the kingpin bearings are heaps bigger, the bearings are spaced futher appart, the swivel ball is thicker and as a bonus the have more lock. It is possible to build tuff Toyota front ends but i does cost a few $$$$ but in the end its worth it as it can be done with all factory parts and a special housing. Its worth noting that small CV inner axle wont fit to and 80 CV. As for the strength of 80 series high pinion front diff they are o/k traveling forwards but lack strength in reverse, if you give them a hard time or if you have much more power than standard.
As to the GQ front high pinion they get the thumbs up there tuff, there cheap and you can fit Toyota side gears to the to run Toyota axles.
GQ CV's arn't the answer and they have problems with bigs wheels as do the wheelbearings they are too close together and get loaded up and fail.
If you were to put a GQ front diff assembly in a 40 the spring saddle ends up on the diff pumpkin as GQ's have a very short R/H axle.

I could keep going on but what i have written is from my own personal experiances. :black:

So bisicaly you are saying exactly what i said but you have gone into more detail.
But it looks to me that you beleive a stock 80series CV is stronger than a LONGFIELD or a C.O.R.E cv?

I have been running LONGFIELDS now for approx 8 months with no failures but i could break a stock cv at call. On average i could break 2 stock cv's in a day of wheeling. I run 38.5/16/15 Claws and there are a couple of other guys on here also running 38.5s and larger that have had a good run with the Longfields.

I have seen 80series CVs break just as easy as a hilux cv as well. And lots of them.

so tell us something new? apart from the fact that 80 series CVs are commonly halfway to failure due to the loads put on them 3 tonne truck, constant 4WD in the luxury models. 80 Series CVs are not the answer for big tyres, unless you are the shed guy, in which case suzuki gear should be fine, as:
1 you dont wheel
2 you drive like a girl

Your longfields may be o/k but i fail to see how changing the CV fixes all the other problems with the inner CV spider, king pin bearings and swivel balls . What your your stating inducates your a flat ground wheeler and i very much doubt you have seen a 80 series CV break, probably heard of one breaking!
