Outer Limits 4x4 Board

Gday guys

Just like to hear sum thoughts on runin either full maxi set up or swapin over to nissan diffs and housings in a range rover any advice would be great

Cheers

Chris

your best, bet and strongest setup would be GQ nissan diffs.
if you want it stronger and wider again, go GU with a h260 rear.
if you want totally unbreakable, put longfields on the GU/GQ axles.

with the gq/gu, you have the weight, the axle strength, the centre strength and the width.

Nissan, But GQ CV's are weak as piss

GU diffs are the go. Even the 233 rear is unbreakable.

what makes them weaker than any other NTN cv joint as fitted to most jap 4x4s .being in the cv joint and driveshaft industry i can tell you i sell 20 times more toyota and rover cvs than any nissan cvs ,toyota being the bigest seller by far followed by rodeo, pajero, patrols would be the least selling cv and im taking GQ here as ive only ever sold a couple of GUs

there are people fantasizing about nissn patrol CV's being weak.
its their only recourse

truth is they are stronger than factory toyota or rover CV's

and by god do they cop more of a pounding

Aren't Landrover Defender County 110 CV's halfway between GQ and GU?
Landrover Salisbury diffs are supposed to be something like an equivalent strength to that of a Dana 60.

sort of and yes - D60 and sals are almost identical (except for axle shaft size).

Copy of what I posted in the same thread in the rover section:

ISUZUROVER wrote:A Nissan H260 rear (biggest nissan diff) with an ARB or prolocker would be about the same strength as a salisbury with an MD locker.

Nissan front diff centre beats a rover diff by miles, but apart from that it depends what CVs you are running - lots of options to fit longfields, longtracks, cvunlimited or ashcroft (all 4340/4340m and very strong) to a rover - what about a GQ?

GQ cv's are the same size (bell diametre that is) as hilux, they are made by the same company, same material, therefore just as strong/weak.

As far as real world breakages go from what i have seen hilux and gq are on par.

GU would be where id be spending money with nissan gear, not GQ, unless of course someone makes chromoly stuff which ive heard is coming soon.

No, the bell is bigger, the star and race are exactly the same (as is Range Rover) but the Nissan bell has a lot more meat in it (~8mm bigger diameter and no flat spots machined into it). The GQ bell very rarely breaks, the star or race usually give up the ghost.
The GU CV is a good product, but the problem with it is the CV is strong enough to transmit the required force to break the stub axle

gu are much stronger, you can either put GU diffs in or get GU nuckles and weld them onto GQ housings

also, you get get longfields onto gq-gu axles aswell.

Not true. Outer dia of GQ bell is bigger than that of Hilux.

Again, not true. Most peeps over here with Lexus powered Hilux's swap to GQ diffs due to problems assoc. with std Hilux CV's. But when worked hard, GQ ones implode the inner star. This is why strengthing with a ring machined around the bell isn't effective like on 70 Cruisers etc.

Sorry boys, i was only saying that cause i've replaced alot more GQ CV's than rover

Fantising??? i just said nissan was the better option, no saying stick to rover stuff there and the GQ CV's are shite, put in some gu's and your laughing

Mate, i have measured them myself, i know its true they are exactly the same diametre (90mm) go an pull a gq cv and hilux one and actually measure it and youll see.

and from what i have seen, gq cv's break just about as often as hilux ones, and i wheel with an equal number of both vehicles. You would think they would break more in gq's considering the same dimesioned cv under a bigger truck.

lmao @ all the nissan owners getting emotional about there diffs and cv`s.

It is a well know fact that cruisers have ALWAYS been better then nissans

Seeing this thread dosnt involve a toyota (which is a shame, knowledge is wasted here ) I would go the the maxi`s.

Best you go measure again then. GQ outer is 94mm dia, Hilux is 90mm dia.

From memory, the star are the same size on both, so the GQ has a more substantial outer bell. I believe this is why the most typical mode of failure of the GQ ones is by imploding the star. The outer bell is broken much less frequently.

This is true, the Bell of the GQ is slightly larger and thicker, but the Star and Balls are interchangable between the lux / cruiser n gq cv's...

Kind of off topic but how strong is the standard (not the big one) gq/gu rear diff? How does it compare with a ford 9"?

Jimmy

GQ and Rover CVs (as per Disco 1) are the same outer diameter, but the input axles size is bigger on the Nissan, so overcomes the Rover weakness. I think a Toyota star (60 series) will fit into a Rover CV - interesting....will try it one day, but they look exactly the same. Same factory build I guess).

Ford 9 inch diff is the strongest diff of any. It has to do with the gear cut, contact surface area and double bearing pinion support. There is only one reason why this diff is the choice of dragsters and others heavy metal units - cause it is soooo strong.

so u cant compare the two? Gq and ford

i would reakon the h260 rear would shit all over a 9" rear
looking at the 9" and then h233 rear, i would still put my $$ on the h233

the dragsters dont just use a 9 out of an old x..... model ford, they run specially cut, shaved balanced on shortened axles which cost a grand and up.... ive seen a locked nine blow up by a guy doing a burn out on the road and dirt. the different traction just fudged it bad enough that i laughed and kept driving home while he called a towey.

nines arent the strongest they can be made it though, just like dana 60s, theyll break just as good as most high end diffs untill you put some custom strength in them. when it comes to custom made diffs and axles i dont think many can beat the strength of a 9 and A D60... my opinion (id be running both if i could afford them the way i want them.

They have 3 pinions bearings, 2 tapers and a needle roller, Not 2, standard form, they aint real strong, well the CW+P's are but the carriers are shite

I'll pay the H260 comment, NOT H233, seen a few of them break, i think your magic engineering looking eyes need adjusting, But remember the H260 is a truck diff, even F trucks move to dana 60's when they get bigger

So how good is the standard h233? How much power would u be looking at until u started having issues?

Lots, brake burnouts on 35's break them regularily

the 233 is recomended as the rear for most project vehicles not going to the extremes of danas and 9s. itll hold its own to more than enough power to satisfy or to ruin everything else on a 4wd

What Cloughy said... In stock form, as seen in OZ, 9" diffs are pretty weak - the cases and (small) axles usually fail. All the dragsters run nodular cases and big axles to make them strong enough.

all the big cars 1000hp+ use aluminium cases and aluminuim spools, billet axles expect to pay up to 12k for a mark williams set up no brakes

Fark u guys sure know about ya diffs looks like the only weak point in the maxi set up is the CW&P and there not that hard to break either in the rover..
Maby a rear salsbury mayby the go with maxi internals as it would be a straight bolt up nearly thanks for all the info guys ..
