4wd Systems Diff "Lokka"

Thanks Mickl,
I have read all the 4wd systems info on their web page...... but it is their web page & it's always like talking to a salesman. I am hoping for some user feedback.

Thanks Rowler

Thanks Mark,
I am looking for the 4wd systems brand & have not seen anything on th threads.

Thanks Rowler

Sorry Mark...... Found the stuff on diff lokka's
Bloody blind, after reading it still confused though

Thanks Rowler

Rowler, What exactly are you wishing the diff lockkers for?
As far as I can see the choice is control the lock yourself- Air lockker(this is my preference)
Or Automatic lockkers such as Detroit or Lockrite. I went to a diff specialist the other day and he was saying that he had pulled out a heap of Air Lockkers from Defenders for the Army and installed Detroits prior to them going to Iraq. It was just that the SAS guys didn't like the manual operation which given that the someone may be shooting at you and your pushing buttons rather than a trigger, is understandable. He showed me how the Lockrite had worn down the teeth on the diff but I assume that this was a rear diff and may have had many k's under the belt.
You will be confused and if you really want to get confused, post a thread about fridges or tyres.
It is each to their own and there is no perfect answer... Sorry
Regards

you sure you broke your wheel studs due to the locker ? first time I have ever heard that . Did you set it up by the book ? not been smart here , just cuirious . I was trying to figure out why you would fit one in the front and not the back ? it you think it broke your wheel studs due to the locker in the rear , I would hate to think what it would do to your CV's

I prefrence is air locker front , to disengadge when I like for steering , and lokker for the rear, I find it releases fit , even less torque than a LSD in a Patrol. I find that if torque ic comming from a wheel . It disengadges real quick , if the torque is comming drom the tail shaft its rock solid .

The reason I like this set up is due to the fact that mine is a costant 4x4 so manuel lokker for the front in out of the question , and our LSD are non existent after 10,000 kms from new

gday eric.
whats your thoughts on a lokka in the front of my gq.
thanksback by popular demand

Why cant you use the auto locker with auto hubs? I though the hubs would only engage once the front axle was driven via the front drive shaft.

I had a GQ with the 4WD systems locker and it made a huge difference. Now have a GU and should have swapped it across but it made selling the GQ easier and I reckon I almost got my money back on it.

Wayne,
I have been to told (but obviously have not experienced) that a front lokka with auto hubs can "trick" the hubs into locking. This effectively is like driving in 2WD but leaving your hubs locked in.

This in itself is not a problem, but at the end of the day I, like most others, unfortunately spend more time on the blacktop and do not want to be driving with effectively locked hubs while in 2WD.

If others have any experience of an auto lokka with auto front hubs, I would like to know if you have experienced this "false locking" of hubs.

Cheers

Simply change the hubs to manual ones. I.ve got a 4WD systems Lokka in the front of 95 GQ. Bought it second hand from a mate who runs a 6.5litre turbo diesel through it. Its been treated like complete crap as the guy thrashes the bleep out of his car, always breaking axles, CV's and hubs but there wasn't a mark on the lokka. He scored a whole front diff after breaking both axles and 1 CV in a single outing and it came with an air locker. I changed the hubs because they can stick some times and this may have given me trouble with things trying to lock/unlock.

"save your money"... Truckster I think you need to check the prices of an air locker. By the time the air compressor is fitted, you are looking at $1500 - $1800 for a single diff. Compare that to ~$800 fitted for a lokka.

By your comments, it seems you have the air locker, not the auto locker and thus no first hand experience with auto lokas. I agree the air locker is a good locker, but so is the auto locka. I have mates that have broken air lockers and detroit lockers. Nothing is indestructable when abused.

There are many, many reports of satisifed auto loka owners and I am one of them. I had one in the front of my 80 series and that vehicle did some really hard miles (3" lift, 33" tyres, extractors etc...) in a variety of conditions. It has lasted 7 years and 150,000kms and is still going well (vehicle has over 300,000kms)

Most stories I hear of front locked diffs breaking are front CV joints. This will happen REGARDLESS of the type of locker (air, auto, Macnammarra etc...). And then one can usually trace that to huge amounts of torque, wheels in the air, lots of speed and then landing with the power on.

When comparing the internals of a locker, the auto locker's weak point is that it uses the original diffs centre. A detroit locker and an air locker replace the centre and are stronger than original equipment. So,
an auto locka can only be as strong as the original diff centre.

As for competition, that places an extreme stress on the diff and i would agree with the use of an air/detroit due to their stronger centres. However, you will find that virtually the whole drivetrain has to be strengthened as well (bigger CV's etc...) This is completely different than typical "hard" 4WDriving in a club situation.

Not all "new technology" or designs that challenge the existing crop of equipment is bad. I have read your threads on the 3.0 TD GU Patrol and can see that unless you can fix it with a hammer, duct tape and a large shifting spanner, then its too complicated, unreliable and not as good as a 1950's design with all the technology of that era.

Cheers

Mark..

I have no lockers, I dont need them, havent yet in 2 years of high country, toolangi, walhalla, Wombat, etc etc...

If you want a Lokka get one.. on the several forums IM on, including a few with all the top comp blokes in the country, I would save my $$ and go with an Air locker.

The other advantage with Air locker you get a compressor to inflat your tires with... Thats $300-400 saving there...

It costs more for an Air Locker for a reason. Quality.

had that problem once , were a wheel carried took a long time to arrive. I rang and complained , and problem was fixed , I usually receive things within 4days now , nice bunch of people to deal with to . Now remeber we are dealing with Adelaide here lol
