Hi Gang,

I have emailed back and forth to the Aussie Locker people. They tell me that their Australian engineers say the JDM diff is different and therefore Aussie Lockers will not fit a JDM BJ74.

Do any of you have any direct knowledge or experience on this? They have asked me to check this out as they would like to know if the info they have is correct. I assume it is accurate.....

Thanks,

Bruce

TOTAL BS
same diff center as sold here

[dieseldog]

The only possibility I can think of that would make this partially true would be if they are referring to Landcruiser II/Prado/Bundera. My 93 model does not have regular land cruiser axles, but instead axles that are similar to a Surf/4Runner. Smaller ring gear I believe. These cruisers are also referred to as Light Duty models. But even if this is the case, Aussie Locker makes a model for these diffs as well.

Perhaps they were referring to my Ltd Slip rear diff. But they do mention on their web site a setup where you leave the Ltd Slip on rear and add Aussie lockers on the front.

And Wayne, I love they way you don't mince words.

Thanks,

I have one set in my BJ74 and just but another set of Factory Cable lockers and they are the same. Wayne (as usual) is correct

Cheers,

I researched that a while back and I think Aussie Lockers didnt make one for the full floating rear ends found on JDM trucks.
BUT .....I'm old and forget

[denis]

it's not the full floating thing, it's the differential that would matter... I would bet that the LSD carrier wouldn't work with the locker ?

[The Dude]

My cable locking difs on my HJ61 are different then my other difs. Totally different bearings and set up.

[Little Joe]

I did some gear work a few months ago ..... Using some used mine truck diff parts. IIRC. I had one complete 3rd member and and two other gear sets all complete with 4.56, 4pinion factory LS.
(I don't know what exact model /year the 3rd member came from)but the 3rd member housing itself has different external rib reinforcement etc then any I have seen before.

I used a earlier open carrier with a lockright and the mine truck 4.56's in the mine truck housing........no problems.
However this mine truck gearset WILL NOT work in a (for example 1985)third member housing. I had to get an aftermarket gearset to allow setup in the earlier housing.

I really would like to know what year /model the mine truck 3rd housing was from??

Any idea Wayne?

Hi Bruce...

The Auzzie will work in your front diff, however not the rear LSD diff. An option is to remove both diff's, but the Aussie in the front diff, and then put that diff in the rear. Then put the LSD in the front. I know Wayne has talked about taking the LSD diffs apart, sand blasting the clutchs, and re-shimming them quite tight when back together. I have no experience with this.

Little Joe...were the external ribs pointed up slightly, instead of straight out?

Is it possible there are two differnet housing castings?

Some diff housings have the radially oriented ribs:



Greg_B tells me these are the newer housings.

Some others have the horizontal ribs, as do the cable and the electric diffs:



I wouldn't be very surprised if some aftermarket lockers do not work with some housings.

the original question was would the aussi locker fit in the BJ74 diffs, yes it will. they will not fit the cable lock diffs or the limited slip diffs.
grab a center unit from a CND 70 or 42, switch the companion flange if needed, and install that in the rear diff or shim the LSD and stick it in the front as Greg suggested...
soemtimes i ramble on and on, other times i am in a rush so few words are typed...
sorry if i offended you.
cheers

Hi Wayne,

No, you didn't offend. I was grinning. And thanks.

Dave , the top picture looks like the housing I referred to..........

The factory 4.56 gearsets will not work in the earlier housings although the complete pumkin is still a straight swap.

Lowenbrau just brought up a good point I had forgotten about on another thread. The FF rear will not like an auto locker. Somewhere in the depth of Mud or Pirates are some posts about upgrades to the studs and adding two more dowel pins to the hub and axle flange. Those would help I imagine.

Greg to you mean a specific auto locker or all auto lockers. I have a FF rear axle in my BJ42 and I originally put a Powertracs locker in it with no problems.

i have found a specail washer (slightly concvex with a seraded side) that works great even with my welded. i would recommend upgrading the dowels to one size larger...
cheers

[lowenbrau]

Welded is easier on FFs than auto lockers as far as I'm concerned.

These might be another trick for helping keep things tight.

I have a source but have to buy in volume.

[crushers]

that looks just like the ones i was talking about, they are available at Tri Ad...
i can understand what you are saying, the welded doesn't bang like an auto locker would, it is more even stress stiuation...
cheers

Wayne, what did Zepp have in the back of the 7*? I believe he said he had problems with it. I also recall reading a few years back about this issue as people posted up their experience's. I do not recall if it is all, or lunchbox types like the Auzzie.

gb

[crushers]

he had a FF, he also was running a lock rite. the hub was completely messed when i got th etruck back... i know he tried to fix it but it was just too far gone...
i am running an elec locker in the back now but i have not ran it long enough to give it a fair call...
cheers

Hi Guys,

My 1988 BJ74 build plate says my axle code is K085. Reviewing the Birfield thread at

http://www.birfield.com/modules.php?...EXT/09-01.html

my axle is as follows:
Ring gear size: 9.5"
Ring/pinion gear ration: 4.111 (teeth - ring: 37; pinion: 9)
# of spider gears: 4 (applies to Limited Slip Diff)

So.... this code applies to the rear diff only.

How would I find out about the spec on my front diff? Anyone know what it is?

Thanks,

Bruce

[Greg_B]

Open diff
Ring gear size: 9.5"
Ring/pinion gear ration: 4.111 (teeth - ring: 37; pinion: 9)

Unless someone has monkey'd with it in Japan...

You gonna put the LSD in the front, and the Ozzie in the rear?

In the front you have the same diff .. in fact, you can change 3rd member from rear to front .. easy.

Are you saying that if you have a land cruiser that came with LSD it has them in front and rear? I thought they only put LSD in the rear.

Thanks,

Michael

[crushers]

rear only from the factory...

Yes only on rear from factory, but you can move easy this LSD to the front diff and put a locker in rear ..

is the same 3rd member front and rear ..

[crushers]

as long as it is older than 1990 then yes, after 1990 then it depends on the front diff size...

that's right ..
