Diff Locks or LSD for BJ74

[letsplaychicken]

Hi,
I have been thinking of putting True Trac LSD's (the torsen kind) in my BJ74 but am also looking at a locker alternative.

What size diffs fit in the front and rear diff carriers - I am not knowledgeable on diffs, but I think they are 4.11 ratio's same as rear of 80 series? But how many inch are they? Anyone got aftermarket lockers can shed some light?

Thanks for your help.

lockers

I ran a set of Aussi lockers front and rear in my old 70. They were cheap, worked great off road and were easy to install without having to pay to get a diff set up. There were some noticeable negative handling changes on the road though. If I were to go with lockers again I would get some selectable ones. Pony up for electric lockers out of an 80 or, if the sky is the limit cable or ARB lockers. If you drive the truck on the road more often than not selectable lockers are the only way to go.

IMHO anyway.

You have the 9.5 in the rears, and pretty sure the BJs have the same size in the front, differs with year and model. Some of the newer trucks will have the high pinion front like the 80 series.

I have the factory LSD in my troopie right now, and am underwhelmed with it. No experience with the True Trac.

Lunchbox type lockers are great because they are cheap and do not require any wiring, air lines or compressors. However, the road manners can suck a little. I had an Aussie in the rear my 91 FJ80, worked great but you'd get the clunks and a jerk every no and then on a tight turn. If you have a selectable transfer case, a lunchbox is fine in the front as you run 2WD on the roads most of the time.

Air or electric are better for a DD type of truck, and the selectable option is great. E-lockers or cable are cool, some complaint threads about the long spline axle shafts twisting. Air lockers are great too, and there are complaints about o-rings blowing out or moisture getting into the lines/locker causing failures..

Do a search, tons of threads on lockers in the 40, 60, and 80 forums.

I am actually upgrading to the new TJM Pro lockers on my truck for something a little different.

I have ARB airs front and rear in mine and find them great, no problems and do what they are supposed to.

LSDs are just an expensive open diff.

Don't waste your time.

Yup X3 - I went 60 series CABLE lockers converted to AIR in my BJ75 simply AWESOME.

cable locks
electric locks
aussie locks

ARB are crap
limited slip are poor.

ARB are crap

Dont listen to this dribble, they are far from crap, not perfect by any stretch of stretch of the imagination but if properly installed can give hundreds of thousands of kilometres of trouble free driving.

The older 3 piece lockers IMO are better than the newer design lockers, the older ones take more operator ABUSE.

 

[crushers]

hundreds of thousands of UNLOCKED trouble free use ...

 

[Hulsty]

Locked and unlocked yes, why do you drive around with your cable/Elockers engaged all the time? Pointless and accelerates various component wear.

I've done a little tar driving with my rear locker engaged and its a pain in the arse. Personally I dont rate the lunch box type lockers to highly, if going a auto locker a replacement centre type like a detroit is a much better stronger option.

 

[crushers]

the idea you stated that an ARB is good for hundreds of thousands of km is mute. E/locker, Cable Locker, Aussie locker, ARB are used to LOCK for traction. if they fail when in use is what makes them a POS or a good locker.

if you actually drove hundreds of thousands of km off road with the ARB locked and unlocked and locked etc then your statement will make sense. but any locker that isn't in use will last the life of the truck.

ARBs are s***.

the same can be said of winches. you can have a winch that sits on the front of a truck for decades but that doesn't make it a good or bad winch. if it doesn't do the job when asked to do so then it is a POS.

Still licking your wounds after ARB-Safari roasted your ass for plagarising their snorkle design Wayne?

ARB lockers are the most prolific lockers in the world and there is some good reasons for that.
The Tuff Truck challenge 09 in oz saw every single competitor running them.
And no,ARB dont supply them free of charge for the competion,I cant even see them in the sponsor list.

 

[crushers]

nope, there wasn't the demand. turns out a 5% change in design eliminates any possibility of ARB winning a case.
no demand, not worth the effort.
plus
ARB snorkels are a distance second to factory and i scored a great deal on factory setups.

so thrribbtt on that idea.

Rosco, i learned decades ago that just because the Lemmings of the world go one way that doesn't make it the right way to go.

i have had zero issues with factory lockers or Aussi locks and i have watched numerous times the ARB s*** crap out when needed most.

so

run what you want, personally i will pass on s*** that doesn't work when needed.

Factory LSD , they kind off work when the clutches are in good shape otherwise a glorified open diff

Factory Cable lockers, sometimes you have to match the dog teeth, very strong but not always 100% postive action

ARB, I used to hear they only hold up to 33" tires (the older models) Mine have worked well for quite a while 100% positive action, TJM also

I have ARB and Factory Cable Locker, I prefer ARB

There are electric lockers , sometimes electrics and water dont mix, so unless they are modifed and waterproofed, forget it


Rosco , Nice to have you back!

Wayne , First you cut my Prado down , Then you cut my Low pro winch down, and now you are cutting my ARBs down sheeeeeesh it never stops

 

[crushers]

don't take it personal PradoT, i pick on everyone equally.

(can't help it you are still in your Cruiser infancy)

 

[gofast]

Hoping to contribute something useful, having had LSD and upgrading to an ARB, I'm somewhat saddened by the tone of this thread. So as it turns out I've got nothing to say other than glad to see ned kelley


Wayne, your opinions are sure interesting but sometimes take away from the usefulness of the thread. I much more prefer practical application and inventiveness which you are not short of.

Oh yeah, everyone's got one. Or should I say opinions are like wayne, everyone's....

So that means you will pass up on factory E lockers? Which are just as prone, if not more to issues as any other locker, yet a s***load more expensive to fix and more difficult to get parts for and possibly harder to fix if things go pear shaped. Good luck removing the centre from the housing if it gets stuck engaged.

What problems have you experienced with ARB lockers? You seem to be happy to bag them out with little explanation, I know of a few issues they have.


An issue guy I know of had a $2600 repair bill for his factory fitted E lockers on a VDJ79, a stick got caught and the actuator and housing was split and some wires pulled out.

Granted the air line from a ARB can also be ripped off, though careful running near eliminates the problem and if it did happen it would not cost $2600 to repair!

I'd have to check but I "think" their warranty was only up to 33'' tyres, though they are capable of much more. I have the old RD33 and so do many mates with 35''-36'' tyres with no locker problems.

I mate recently put a TJM Pro Locker into the front of his Nissan Patrol, he drives like a mad man, TD42, lots of boost and super swampers, has already damaged a new style ARB, will be interesting to see how the TJM locker holds up.

 

[crushers]

actually, the E/locker isn't as prone.
how do they go pear shaped?
and
to show you what you really know about the elocker, to remove the locker from the housing it needs to be ENGAGED. if it is open then you need to pull the cover on the side of the motor (3 bolts) pull the actuator bolt (one bolt) and you can engage the locker. takes about 3 mins to accomplish and you can pull the locker out.
your buddy needs to start working on his own truck instead of paying a Mech to do the work.

air lines ripped off is the biggest issues but also the air line freezes in the winter so when winter wheeling you don't have the option of ARB engaging, a true PITA when the snow is coming down and you have a steep slippery slop to climb.

other than those issue they seem to do the job for some..
