Outer Limits 4x4 Board

Any one had any problems with a Lokka Diff Lock from 4wd Systems as I am thinking of putting one in front of the GQ got an lsd in the back.
There about $695.00 at the moment which is what I can afford.
If you got one and think there OK let us know as well
Thanks regards graham

Don't put it in the back. Put it in the front if you are going to get one.

Most on here will tell ya to save and get an airlocker but I find for what I do the auto ones are good.

Depends on what sort of driving you do.

Main thing is not to put em in the rear.

I have one in the front of a GQ and know of 5 others in the front as well all GQ's and only one problem has risen in the nature of not unlocking to well, but it's running is in it's 3rd car now (we havn't had the time to pull out and check why, maybe a spring has come out).

I think there good because you can still steer and power on at the same time. I reckon the price is good too.

I did have one in the back off a Hilux years ago and wasn't too bad, but sometimes a real pain in the arse.

Hope this helps.

I have one in my GQ shorty in the front - works well for the money. Also had one in the front of a hilux.
Mine is starting to "click" when pushed hard but I am confident that it just needs the clearance set correctly.

Makes steering a little harder but for rock crawling its really good, especially downhill. For mud it tends to want to go straight on at times.

I am a little worried about long distance cruising over gravel tracks where I want to be in 4WD but not locked, just under 80kph. Might want to steer me off the road.

Have not used the "locakright" or "detroit" versions. The "lokka" works well.

well this is the first thread about lokka's where nobody has said "just save up and buy a froggin air locker" good to see.
I am also interested in getting one for my patrol, looks like i'm getting an lsd for the rear which i will make up really tight, but for the front who knows???might try and get one of these?
any body had problems / worries about them being in the front???

Been interested since I already have a rear factory vacuum locker, whether a LSD (converted Pathfinder LSD) or an autolocker would be suitable for the front.


If I could get a vacuum locker for the front I would, no question. An airlocker - the price of buying 1 is 2/3 the price of buying 2 when you include air compressor and I already have one but ARB dont like you using others.

With being able to turn the rear off the steering shouldnt be too bad... even having a welded rear affected steering a lot.

So I can't see a scenario where Power steering plus Front LSD or Autolocker and 2" bigger tyres is worse than welded rear diff + no power steering + 5" bigger tyres.

i guess if you are on a tight budget you may be able to justify it however
i just removed my front autolocker in preference for an open centre because it made the car steer like a real pig when in 4wd at any speed above about 10km/h. If the car is only used for slow low range work it may be ok but the typical phrase-I would save my pennies up for an airlocker

i had a vacuum locker in mine and they are so different to an air locker. turn the switch on and they engage but maybe not fully causing damage if under load. its alright if you have plenty of time but you cant just turn them on and expect them to be fully engaged, once there in there fine but once they get burred edges they slip a notch and make a cracking sound and get damaged more. they just dont have enough positive engagement to hold them locked. also didn't disengage properly everytime. sometimes it would stay locked for ages. i used mine heaps and it was great, i just wouldn't bank on it working forever. i have gone air locker now and its great, but am thinking of the traction control from sam for the front for its ability to change between vehicles.

This thread is good I'm probably importing one soon from the states soon for the zook. We can land zook ones for between $268 and $370 depending on import taxes

This might sound strange..... But I think that the torque/power the motor makes can make a difference especially with the front auto lockers.

I had a 4wd systems one in a 1hz na and you could hardly tell it was there most of the time.
I currently have a loka lockrite one in a turbo intercooled patrol (ie much more torque/pwer and I notice it a fair bit more.
On the beach for example if you are into it and change up a gear it can kick the steering wheel a bit. Power steer helps a lot!

I really don't think it is that bad but. If ya steering locks up a bit. then back off on the power and they normally unlock. Going down hill can be harder on em.

I don't think they are suited to fast comps etc but for general 4wd they are great. I do think it is great not having to worry about switches etc too.
You can normally steer pretty well most of the time.

Pretty sure that 4wd systems doesn't recommend you use em in the rear.
I wouldn't ever after a mate took his out of a hilux and put in front one.

I am a Kiwi with a SWB Patrol/Safari (import) and have fitted a Lokka in the front and a factory vacuum diff lock in the back.
The steering does become stiffer/heaver and I find that you must turn the steering wheel more to turn corners than before I installed it.
The turning circle is also a little bigger but you get use to it.
The Best thing about the Lokka is that it is always working when you need it.

My import Safari (2nd hand from Japan) had a larger 4-pinion diff head (heaps stronger than 2). The Lokka only works in a 2-pinion diff head so had to buy one of these as well.

Have had this set up for over a year now with no problems.

I don't mean to hijack the thread, but some people have been talking about putting LSD's in the front diff...
Has anyone transplanted an LSD hemisphere from the rear of GQ into the front?
I have heard contradicting stories about whether it will actually go in regarding axle spline size/shape...

Nope.... diff and axle sizes front to rear are different so can't be done. Some are H233 front and rear but have different nos of splines.

Correct me if I'm wrong (not that you'll need the invitation)



What in theory can be done (never seen any proof of it) is that the Pathfinder rear LSD centre can be fitted in the Patrol front, with the Patrol R&P.

It'd be a professional effort to do it unless you're equipped with the right gear to measure backlash and all that stuff.

As to whether or not it's better than a locker... it won't have the same 100% lock unless you're applying power, but won't solidly lock up the steering as badly either (especially off the power).


The questions are:

How much $
How much will it affect steering
Will it do any harm to CV's (especially needing that extra power to lock up)


I think it will cost similar in the end to a lokka... but happy to volunteer if someone has the right Pathfinder diff spare.

Otherwise for now it's a "discussion item"

the spline count, ans shaft size are completely different, they may have been saying you could fit an MQ LSD centre in

GQ front - 31 spline and 32mm shafts
rear - 33 spline and 33.3mm shafts

MQ rear - 31 spline and 32mm shafts,

id say, theres a possibility you could use an MQ rear LSD centre, and put your diff gears into it, and then put it up fornt of the GQ

I tried a Lockrite in the front of a LWB Petrol GQ. Put up with it for 6 months and then sold it

Bloody dangerous at times. ie driving a long with hubs locked on gravel rds as you do turn into corners, steering heavy, had to back off mid corner, steering light, direction change.....cool not

Driving along slippery clay rds in 4wd, slight corners, nissan goes straight on, too slippery for diff to disengage properly.
Down real steep hill in low range, hairpin turn , cant turn bloody steering wheel, diff wound up and wont unlock.

And dont say,, oh get out and unlock a hub.. wont help after the fact..
who want to do that anyway..

Saved for another year and got ,,, dont say it Baz,,,, an AIrlocker, never looked back.

Can use any compressor you want too, as long as you use. An ARB pressure switch and at least 1/2 litre tank.. no probs

Ozy1, are you sure the MQ 31-spline rear has 33.3mm diameter shafts? That just seems odd in the first place, and ARB's application guide shows it with the usual 32mm shafts. All 31-spline shafts are 32mm, all 33-spline shafts are 33.3mm in the Nissan line that I know of, though I'm still learning.

Check out ARB's application guide, looks like the 31-spline WD21 Pathfinder rear application uses the same ARB part number (RD09) as the GQ front, so I'd say the OEM (or any other) centres would interchange just as readily. In fact, other than crown wheel bolt size (and of course shaft spline/diameter) differences, I'm curious what other factors could possibly affect interchangeability across the H233B range.

Interesting to note that ARB indicates there are 34-spline H260 diffs (with no locker application), and also does NOT indicate a 31-spline H260 in the mix (but I learned here there is such a thing). Anyone know more about either?

Hmmm.... reliance on ARB for a full list of patrol intechangeability will not get you the full story.

34 Spline H260 is found under some of the new Leaf sprung GU cab chassis models.

sorry bout the typo on the MQ shaft, it is 32mm, and i fixed it in the above post.

i blame the fact that i havnt been well for the past 2 days
