I want to put some Nissan axles under my Landy.

I have a pair of MQ axles already, but thinking of buying some GQ axles instead, due to them being a bit more common.

My question is, are there auto lockers available for these axles? Had an auto locker in my hilux and it was great, but I can't seem to find any for the Nissan diffs??

Just trying to nail down which axles to use and what is available for either axle.

Cheers

Can get them for the front or can use a Terrano LSD.

lockright do front for gq also the rear mk/mq diff head is the same as front gq diff 31 spline

Have got some

Sweet, will get the mq diffs stripped and fit a rear one.

I feel a dumb ass for not seeing them ones myself, I think I concentrated more on the gq rear though.

Cheers for the info guys

Suzolla, il be in touch soon

Just having a bit of a read through stuff before I go ordering bits and making the mq axles fit, this part http://www.justdifferentials.com/PT3220-p/pt3220.htm
States that it fits a gq rear diff, but everything else I've read or been told is that only the gq front can run an auto locker (the same as taz said above).

Has anyone got a gq with rear lockrite?

99% of gq rear diffs are lsd to fit lockers you need open they are out there but rare of hell personally id shim the rear lsd they work great and auto in front which is 31 spline but most likely 2 pin spider

I can tell you from experience the mk/mq front 29 spline isnt as strong as a gq

Cool, cheers taz. That's the sort of info I'm after.
Il keep an eye out for gq axles I think, I want it to be as strong as possible as I'm pretty rough on gear (ask deranged )

if u are going to spend all that money om Nissan diffs y not get an arb and pegging kit for ya landrover diffs ?

Because that's too obvious and too easy.

Also he would rather reduce the clearance under the diffs as well so it drags more ............

wheres the like button????

Whoa, I got flamed......

If you can do me an arb and pegging kit for $500 then please give me details.

Mq diffs cost me nothing and making them fit will also cost nothing, but obviously you guys knew that before you started talking smack.

If you have a useful suggestion, I'm open for ideas. No need to be a tit about it.

at the end of the day your boat your life but if u read into it most ppl regret doing the conversion

taz01 makes a good point about the MQ front diff. Its the C200 2-pin 8-incher, in something like a LWB Patrol thats starting to push the strength boundaries. Although the ring gear depth is the same as the H233 GQ front, you're still working with an 8" as opposed to 9.25" unit, heres a pic I just took of MK and GQ front gears side by side. FYI The MQ rear is the same as the GQ front.

The strongest version is the 4-pin clutch LSD version which would fit straight into the housing. Donor vehicle 300ZX twin turbo 87-89, or Navara 4x4 D21 rear.

Another easy mod is to fit GQ outer CV joints to the MK axle, which is an easy mod, only concern for me is that this moves the break point to the axle shafts.

Also The MK diffs are available in a greater range of ratios than the GQ diffs, ie 4.88.

Yeah mate, the ratios is another plus point for the nissan gear, but whether the mq axles will be too low a ratio, I'm unsure.
I will be running 35's and mostly for off road use, so I guess it won't be too much of an issue.
Definately want to run some kind of locker in the back at least, rather than lsd or open, and the lockrite I put in the lux worked a treat.

Can you point me in the direction of some of these that regret doing the swap? I would like to get more info, I've only spoken to a guy in napier who did a gq axle swap and a couple of forums in Aus and the one that Turoa did. All seemed to be positive about the swap. I would like to read about the ones who regret it though, and find out why they regret it.

Now re the whole clearance thing, check this out:
Heres a photo I just took of the Nissan GQ Patrol 9.25" ring gear next to a Rover diff.


I'm not going to dismantle the Rover diff for the sake of this demonstration, but the Nissan gear is only slightly larger in diameter. Eyeballing it I say the Rover looks like about 8.5" or Dana 44 size. So is the loss of clearance caused by case design, or...?

Now heres the 8" Nissan MK Front next to the Rover diff.


Here is some photographic evidence that demonstrates how the Nissan 8", like the famous Toyota 8" is actually smaller and more compact than the Rover but much stronger by its very design. Note depth and thickness of teeth. Both ring gears are standard cut, similar ratio.

Now where's the 'like' button !

the mk/mq C200 diff std ratio was 4.6 and the problem for it being weak is the spider gear pin is 17mm if you drill it out to 19mm you can use a cruiser pin then you wont have this issue as you can see i had a lokka

Aulro has a few who have done it can't be bothed looking for the links
Pirate 4x4 has a cupple of good builds. As I said do it that's what u want just don't do it with mq and I'll bet u right now u can't do the whole conversion for less than a grand

Are you saying I can do an arb, pegging and lower ratio Landy diffs for under a grand?

Not at all I'm just saying u can't do saff diffs on the road for twice what u recon if will cost. I'm not been a hater I have looked down this path and it was not cheep to do I even have all the rear brackets and spring seats to do the conversion
