nice write up.
so to clarify, you can engage the ARB under full throttle in the mud with no repercussions?
(since you say the electric and cable should not be, and i agree with that statement (read common sense usage))

Uh, no, not a good idea with any kind of auto locker. But with a good many dog teeth on the clutches the ARB engages pretty much instantaneously whereas the electric and cable locked units do not. But then you already know that...

I see lots of otherwise intelligent people doing really stupid things with their toys... no one has, to this day, developed a warning label that indicates how common sense should be appropriately employed.

okay, to clarify, the rear full size e/lockers are 2 huge teeth but the small e/lockers have numerous small teeth.
so in reality, in your opinion and from your write up, the ARB is really no advantage over the factory electric or cable.

the electric has (supposedly since i have yet to experience it) a chance for acting up in water. (i play in the water lots engaging the electric locker as needed on the dry and buried in the water, snow, mud and clay enviroments)

the cable lockers are like anything with a cable, capable of seizing so rutine inspection and maintainence is a good idea but the cables are very tough to rip off.

the ARB has the air line issues with possible freezing in the winter, needs a compressor to be activated so electrical issues could be a concern, possibility of the tiny air line being ripped off and when the final bill is recieved is more expensive the the factory option and you still have your worn crown and pinion.

the lockrite is cheap to install, easy to use but has the 'torque steer' concerns when accelerating and decelerating as well as the potential for 'fish tailing' on slippery conditions.

so it comes down to budget, application and desire of the potential customer.

personally, i will run anything but the ARBastard. should my feeling or experience change then i will be the first to admit any flaws as i experience them.

cheers.
 
There is another option, depending on whether they have a model to suit...

They all have their good and bad points but the ARB in my experience is not as faulted as you seem to believe they are. As for engaging under load, it is not recommended but all the comp guys down here who run ARB reguarly "crash lock" their ARB's under load with V8's screaming, not the best for long term life but certainly they do ok for a few racing seasons. Myself I like to atleast lift off the accelerator before engaging.

What problems do they have at low temps? The lowest I am likely to see here is -4c which presents no issues. As for air line problems that is a poor installation issue, if they give you problems, get a decent installer or do it yourself.

Both my lockers are OLD RD33's and have given no problems (the front has copped a blown pinion to the casing) with the rear covering over ~150,000km since the last rebuild trouble free. For the air lines I run the front with a HD airline (not the blue stuff) along the brake lines to the chassis then cab, the rear runs up the handbrake cable into the cab. If I ever manage to rip them out I will have far greater problems then a leaking air line.

I have experience with only 5 lockrites in 60/70 series cruisers, two are faultless but have had VERY VERY little use. The remaining are now all in the bin from internal issues ( I think it was a cross shaft/pin that keeps breaking). A Detroit would be a far better option.

I've had no experience with factory lockers, only read about peoples issues which have been primarily electrical and wearing of the dog teeth.

As for the $$$ between factory elec lockers and ARB, I dont think there is really much $$$ between it at all, on a new cruisers factory lockers are over 3K, twin ARB's similar and both situations ring and pinions are new (its a new car)

I dont see how going with ARB's gives you a worn ring and pinion over elecs? Unless up there you can buy new elecs with new gears for the same price as ARB's (in that case you should start shipping them down here!)
 
we don't get new Cruisers in Canada so when these guys install the ARB it is in higher mileage units (anywhere from a JDM with 150K to a CDM with 400K).
so
if you want new ring and pinion and ARB and installation time for each then the bill is big.
the new electric locker is a drop in with the 3.7 or 4.11 gear sets already set up, locker already installed so it is a remove old center unit, stick new center unit is and wire, done.

each to their own, i have watched those that brag up the ARB dislike them with in a short period of time.

cold temps are down to -30C, the moisture in the lines freeze up. no ar = no locker when you need it. with auto locker, elec or cable you don't have that issue (or if you live in balmy Oz. each climate zone will have its own problems.

in reality, it is the purchasers money, time and enjoyment. if they want ARBastard then no problem (but it won't be me installing it). everyone has their own choice to make.
 
If you have problems with water in the air, you can use a water seperator/dryer
 
yep, that is true but then you have another thing to be aware of...

KISS principal usually is the best rule to live by...
 
I had an ARB that didn't want to engage at about -30-ish when I was out in Saskatchewan in the early 90s. Quite annoying, really.
