Diff Locker modifications
Hey everybody!
I am curious about changing the actuation of a diff locker.
I want a manually activated diff locker, TJM don't do one for my car, neither do Eaton Harrop, the only option i have is an ARB. However after seeing all the bad press about ARB lockers i'm not really keen to part with my hard earned coin to get one.
However, i wouldn't be as opposed to getting one of those Chinese lockers.
The question is: Has anyone tinkered with a locker to change the actuation method? Is it possible to modify an air locker so it can be activated via cable or electric solenoid?
Thanks folks

Re: Diff Locker modifications
You still got the pajero? I wouldn't think its possible to change the actuator without basically building a whole new locker. If your open to a Chinese copy I would just go the arb as when a Chinese one fails it will take out the whole diff center and no warranty. Is there not a factory option for the pajero

Re: Diff Locker modifications
Seriously?
You've seen a few complaints about one of the most widely used aftermarket difflocks, and you'd prefer to bank your money on the reliability of a Chinese copy of the ARB?
Have you seen any good reports on the Chinese copies?

Re: Diff Locker modifications
Yeah i still got the Paj. It only cost me $600 haha. I have read a few good reports about the chinese ones. And they are substantially cheaper than the ARB that's why i'm open to give them a try. And it hasn't just been a few complaints about ARB, it's been a lot. Mainly having to do with o ring failures, and after market service being woeful.
A mate of mine had them in his jeep and had nothing but dramas with them, every time we went out they were giving him issues. He now has TJM prolockers in his Patrol and they haven't given him a whisper of trouble.
Sadly the Pro locker isn't available for my NH or i would have gotten one in a heartbeat
I suppose with the chinese ones, i get what i pay for, so i won't be too ticked off if they fail. If i am spending what ARB are asking and they fail, needless to say i would be furious.
There isn't a factory option for the front of the Pajero's sadly, only the rear.
I was thinking about the possibility of putting an NM pajero front diff on mine. It is a bigger diff and they make a Pro locker for them. But i don't know how much modifying i would have to do to make it fit. CV's, ratios etc
Not a lot of Diff lock options for the old NH

$600 isn't that much cheaper.

Well then, put an ARB in it you'll triple the value. Add a full tank of fuel and you'll damn near quadruple it
$600 wagon? who gives a fuck, hit obstacles with enough momentum, you won't need a locker

Re: Diff Locker modifications
I think I got a little dumber just by reading this post. I've had arbs fir years and had only one failure due to an old design, and that was in a car that got beat on, I used to crash lock the diffs and they kept coming back for more. But please go ahead and buy a piece of shit Chinese locker so I can laugh my ass off when you get catastrophic failures. Just pull the diff and weld it if it's a cheap beater

Re: Diff Locker modifications
rockcrawler31 if that's all it takes to make you dumber i feel sorry for you. And have you had experience or personally know anyone who has had a "catastrophic" failure with a chinese locker?
If you read my initial post you may have noticed i wasn't really asking anyones opinion. I wanted to know if anyone had modified their lockers, if you haven't then there is no need for you to reply.
The whole purpose of forums is so people can come together and discuss their interests and exchange ideas. And believe it or not, some people have ideas that might not follow popular opinion. Or yours.
And due to the fact that i don't own a cruiser or patrol, there aren't as many options for my vehicle, so i have had to improvise on some things. At least I'm still willing to give things a try

If so, then rockcrawler's suggestion of welding the diff centre is actually a great solution
Cost virtually zero $$, if you smash the diff, get another from wreckers.
Off-road, simply engage 4x4, and lock both hubs, for dirt road between obstacles unlock drivers hub only, and use 4x2, bitumen, unlock both hubs, and use 4x2
I've seen this done by a few people including a patrol with big block Chevy and 37s.
Disadvantage is getting out in mud if you forget to lock a hub.
PS, its actually quite an achievement to make rockcrawler feel dumber

Know anyone who's had a catastrophic failure with an ARB? What's aftersales service like on the Chinese rip off?
Horses for courses. What's your intended use of the Paj? Touring, weekend beater, beach fishing rig??
If its a $600 hack thats going to getthumped around the bush, weld the diff.
I've had personal experience of a Chinese CV failing catastrophically.
That is, a $100 CV saved me $200 to buy, but destroyed $3-400 in associated parts when it snapped like a carrot, and I got off lightly by reusing a damaged axle.
Failure with $600 Chinese locker could equal $600 down, plus install cost, plus replacement diff, with welded diff, failure means replacement diff.

I actually use it for all of the above.80's_delirious wrote:What's your intended use of the Paj? Touring, weekend beater, beach fishing rig??
I did consider doing the diff weld, but only as a last resort. I also thought of the auto lokka. But I have the super select system in my rig so it doesn't have manual hubs and I use the 4H setting when I decide to go into "rally mode" on the dirt roads or if the roads are particularly windy and slippery...cough.....crickets....
The other reason I want to try modding something properly, is to help others in the same predicament. Ideally I would like an E locker, as a few others I know who do. But they don't make them for my model. So I asked myself. "Self, why not try modifying something, either a locker that can fit my diff, or the diff so it can fit an E locker"
As for the below question:
Not a catastrophic failure, just a lot of repeated annoying ones that left my mate with a completely ineffective ARB a few times. We gave him a lot of crap because he kept bragging about how great it was and every time we went out it never worked. He had it fitted by ARB.80's_delirious wrote:Know anyone who's had a catastrophic failure with an ARB?
The chinese ones reportedly have a breaking point of 6412 Ft-Lb = 8693Nm vs ARB 6929 Ft-Lb = 9394 Nm I got that info from the interweb.
Also how did the welded front affect your friends steering?
I'd rather have it and not need it, than need it and not have it...
Re: Diff Locker modifications
Yes, it does affect steering, as any locker does when its locked, with hubs locked.Nittus wrote: Also how did the welded front affect your friends steering?
When off-road, you lock hubs only when you expect to need the locker. Ie, as you approach a difficult obstacle, you lock hubs, and unlock hubs after passing the obstacle
Effectively, you drive 99% of the time in 2wd, and use 4wd only when really necessary . It's surprising how far you can in 2wd if you drive strategically.
I'm not familiar with "super select". I'm guessing you push a button which engages 4wd in the transfer and locks hubs? If so, a welded diff would be super easy. No getting out to lock/unlock hubs. But you then have 2wd, or 4wd with front end permanently locked.
Your super select would help overcome steering challenges too. Deselect 4wd if you need to turn tightly.
I find having the steering affected with the front locked is only a problem on a high grip surface or on flat ground, or in if trying to steer out of a rut, up a rock step etc.
Most of the time a wheel will slip in rough conditions when you need to steer (lockers are usually only used when traction is compromised). Steering is affected worst when there's a lot of load on the driveline. Unload the driveline, you unload the steering. I've often stepped on and off the clutch to gently rock the car back and forth to allow me to steer tightly to crawl an obstacle. Effectively all this does is unload the driveline momentarily to allow you to steer tightly.

Re: Diff Locker modifications
Modifying something like a locker or operation of a locker takes one of the following
1. Mad skillz,
2. A certain amount of arrogance and dumb luck,
3. A certain amount if naivety and dumb luck,
4. Or $$$ to buy someone else's mad skillz
2 & 3 can leave you with expensive scrap metal, 4 can make your cheap solution an expensive one

Re: Diff Locker modifications
I'd only personally weld lock the rear, and leave the front open. Manually faffing about with front hubs every obstacle would get old. The IFS 100 series i drive with an open front and locked rear goes all sorts of places.
Like i said, the only niggling failure i had in an ARB was the cross pins walking out, and even then it was still working, it just became apparent when we took out the centre to do other work and we noticed the cross pins were playing silly buggers. Comes down to "GOOD" installation too, and that's NOT what i'd call most ARB installers. Shit metallurgy on the other hand can't be accounted for regardless of how good the copied design is. And anyone who spends $600 to save $300 on a chinkychong chinese part that can cause expensive failures on other components like ring and pinions, axles etc needs their head read. Which is why i made the "dumber" comment. Either "spend well, spend once", or find an alernative way which is why i suggested a welded rear. Stop encouraging the market in chinese SHIT products.

Re: Diff Locker modifications
Basically, it's a lever activated "shift on the fly" system. You have 2H, 4H, 4H locked 4L locked. It activates a solenoid that engages your front wheels. When you drive in 4H it becomes an all wheel drive. Great if you're driving in pouring rain on a slippery road.80's_delirious wrote:I'm not familiar with "super select".
@rockcrawler80 I do entirely agree with the spend well spend once theory. Most of the time it pays off
