Thanks for sharing and dispelling all those myths that those with $2000 ARB Lockers like to talk about. They are an extremely capable Lokka for sure!

[@dallaseckert4427]

These lockers work well. I put one in my 98ZJ, solid performance...

[@antontaylor4530]

These things are essentially a ratchet in place of your normal diff centre (spider gears). They lock up under power, and force both tyres to run at the same speed as the ring gear, never slower - but if one tyre (the outside tyre) wants to run faster than the ring gear, it ratchets (hence the clack-clack noise) and that one side unlocks. The slower side is still locked to the ring gear. This means shock loading is reduced compared to unlocked diffs, so you should break less halfshafts in theory. In theory...!

[@hombre3000]

I was wondering and this is the perfect explanation. Thanks!

[@simontheyers547]

I see as a load thing. .certain amount of load and it slips. .. I agree with you. .in theory ☺

[@antontaylor4530]

@@simontheyers547 It's not a load thing, and my explanation is not a theory. I'm not trying to be rude, just explain that this is how they're engineered. Ok, if you want the facts of how they work: Your diff centre spider gears are replaced by two solid chunks of metal with ratchet sprockets on the outside, that mate into special side gears with similar ratchet sprockets on their inside face. Under no load, they'll ratchet (clack clack clack as one tyre spins faster than the other - or in the opposite direction even). Between these two chunks of metal you have a pin (the "carrier cross pin") that runs right through the thing, in a hole that isn't quite round. As you apply power, the diff carrier pushes on the carrier pin, and the carrier pin slides inside the slightly not round hole it lives in. This then pushes the two halves of the diff centre apart, forcing them into the side gears and locking them (and by extension, the wheels attached to those side gears by halfshafts). If one wheel tries to run faster than the diff housing, that causes the pin that is forcing the two halves apart back into the centre of the not quite round hole because it's not pushing the diff centre as fast as the wheel is turning. This lets the two halves slip back out of engagement with the side gears, and the whole thing unlocks, allowing the faster wheel to ratchet. (Clack clack clack). You can see this demonstrated at 2:12 in the video, where he pushes one side out of engagement with a screwdriver. In that shot you can also see the not-quite-round hole between the two halves (he doesn't have the cross-pin installed at this point, you can see it on the floor on the left). This is why if you try to power around a corner, they'll make crashing, banging, clunking sounds as they lock, unlock, lock and unlock over and over again. Most people try to coast around corners or at the very least, take corners smoothly without excessive power. This is not theory, this is how they're engineered. Trust me, I have built these into diffs. I get how they work.

[@liamcooper5202]

@@antontaylor4530 Basically it's a mechanical blinding version of a friction plate pack LSD except these lockers come as 2way only hahah. Hate the stock D22 navi LSD coz it was only 1way (triangle and not 'not quite round' hole. Either way I don't know why people can not wrap their heads around the working of it.

[@antontaylor4530]

@@liamcooper5202 They're actually the opposite of an LSD mechanically and operationally. An LSD is a set of clutches, and it'll slip if one wheel experiences significantly different forces to the other. This means that an LSD will usually slip if one wheel is in the air, making them barely better for offroad use than a basic open diff. They're not designed for offroad use, they're for track, drag and street use. Yes, manufacturers have fitted them to 4wd's. But that was more about marketing and mall crawling than offroading. LSD's aren't "lockers" at all, they're "resistant" differentials. A locker can lock up solid. An LSD can't do that (if it did, it would become a spool at that point, not an LSD). A "locker" is either automatic or selectable. A selectable is a diff, most often open but sometimes carrying an LSD centre. You select when it should act like a spool. An automatic is not a "differential" at all in the traditional sense if you look at the assembled components. It's either locked up like a spool, or it's ratcheting. It never, ever sends power to each wheel proportionally to the distance the wheel is turning - it either sends 100% to both wheels, 100% to one wheel (in low load scenarios) or it is unloaded and there is nothing to send to either wheel. Switching between 100% to one wheel, then 100% to both and back again is the reason they crash and bang around street corners when under power. This makes them great for drag cars, drift cars and offroaders, but terrible for track cars and mall crawlers.

[@noobpvptv5176]

We call these types of lockers lunch box lockers in the states. They are really only designed for very light duty use. The sharp edges on the teeth wear out fairly quickly and they start slipping and ratcheting. Most new guys in my jeep club go the route when they first start. But after they have went through 3 of them, they arent any cheaper than a Detroit, which also unlocks when cornering. Both the truetrack and the actual locker unlock. I started out with lock rights, the went to spools, then Detroit's, and finally arbs. For a manual install it and forget it, nothing works better that a Detroit. They will outlast your axles, period. Foe a push button system, arb with braided air lines is the best I have found. I base all of my statements off of 40 years of trail and breakage. There is nothing wrong with lunchbox lockers, just realize they are very light duty going in. Good luck.

[@DriftingDragon74]

I have to disagree with how he states that a lunchbox locker works. Yes the teeth are engaged by default and they will disengage when turning but only under specific conditions. The housing of a lunch box locker where the diff pin goes through is designed with an elongated hole. The reason for this hole design is so that when the pinion turns the carrier the pin that goes through both the carrier and the locker housing gets forced to the side of the locker housing oblongated hole which acts like a ramp forcing the two halves of the locker outward, this applies pressure to ensure the teeth stay engaged. So if you are in 4wd and there is torque applied to the front driveshaft the locker will not disengage until the load/torque is removed. If you have any type of traction on the front wheels while in 4wd they will not automatically disengage when you turn. Depending on whether your 4wd is a manual or automatic transmission will determine how to properly drive your vehicle in 4wd with lunch box lockers. There is a learning curve, especially if auto lockers are in the rear axle. For example if your vehicle is a manual transmission and need to make a sharp turn going uphill when you are sitting a stop light or intersection, to smoothly drive through that corner and give the auto locker the ability to disengage you must first drive straight and build momentum to carry you through the turn then press the clutch and coast through and the locker will unlock. If you try to accelerate through the corner it will create a load on the rear axle and the locker will not disengage and you'll chirp the tires or it will hop through the corner. Load or torque on the differential is needed to apply and no load to disengage. Also if in very slick conditions you may need to ride the brake pedal to add load to the differential to get the locker to engage or to stay engaged.

[@israels.s.7755]

Is it true that front auto lockers are noisy?

The amount of difference it made being able to back up off camber on my neighbors driveway with a plow on the front and also pushing banks around is night and day. One thing they don t mention though (at least for the version I have) is that the "unlock while turning" only works if you are not on the gas so it makes icy roundabouts that have hills interesting hah! Don't really notice it though at speed on a turn you just don't gun it though the corners and all is well.

For anyone trying to do testing after installing one in an SR5, if you only have the front wheels jacked up, you will need to turn the car on, put it in 4wd (may need to move the car a bit to engage it) then turn the car off still in 4wd. With the car off, put it in 2WD. The ADD won't disconnect the front half shaft until you turn the car back on, so the front wheels will stay connected to the diff and you can test as they have done in the vid.

[@alexdevries7594]

I installed one in a 2001 Rodeo. Amazing value off-road mod. Perfect for a vehicle like this with manual locking hubs. Unlock the hubs, shift into 2wd and the lokka is sitting idle. They should be called auto UNLOKKA. They're always locked until a wheel wants to travel FASTER than the engine is pushing it. It only unlocks when the wheel speed for single wheel is GREATER than the input drive from your engine. For example, you're driving up a difficult track. Your engine is pushing you at 2m per second (2m/s). You turn your wheels left. The lokka keeps driving your left wheel at 2m/s. Your right wheel (following the longer path) is pushed [by the ground] at 2.1m/s. So the lokka UNLOCKS and allows that wheel to travel faster. But it doesn't let it travel any slower than the engine speed (e.g. 2m/s). So as soon as you're straight again, it pushes BOTH wheels as 2m/s.

Scarecrow Hunter well I’ve never been to Australia unfortunately. But from what i see from 4WD action. Australia is more hardcore in my opinion. Here in the states we have so many different environments. I’m from the southern states. Florida to be exact. It’s flat swampy and sandy with some areas of red clay. Western states of our country is desert and mountains. Northern states have mountains and forests. The good thing about Australia is that you guys have almost have the same terrains as us. Just no frozen tundra . But in my opinion Australia seem more adventurous than the states because of it’s remoteness. The animals are different from ours. Off-roading here is fun and adventurous as well. it depends on what environment you want to go off roading.

I would recommend installing lockers front and rear, but I’d actually recommend starting with the rear first. Front axles, be it a solid or IFS, tend to be a lot weaker than the rear, and running lockers puts extra strain on the axle shafts, increasing the chances of breaking an axle.

Good point, curious about the durability of these, myself. I don't know if the bargain price is reflected in the quality of the materials used.

[@jaybajan]

what size rims and tires are you running on the hilux?

[@lesliemoreno6709]

Add that to my wish list. Thanks mate!

[@mikhail2400]

I have this exact same locker in my Jeeps front dana 30 axle and it works great but it does affect steering. Any time the diff is just free spinning its not engaged but anytime power is pushed thru the diff it will engage and no it does not disengage when turning a corner unless I let off the gas and allow it to coast which stops the power pushing thru the diff. In 4x4 when turning on pavement the tires will chirp and if im on an incline and take it out of 4x4 some times it wont disengage without me backing up a short ways. I have gotten into the habit of reversing a short distance anytime I come out of 4x4 just to ensure its disengaged. All in all im happy with the Lokka as it really improves performance off roading

[@Raven-cf5qd]

Just a question if the locker automatically disables if one wheel has resistance due to turning will it disable when one wheel has resistance during 4wding ?

[@r.mhaych5021]

Also in order to do the test that shauno did at the end when the luxy was on jack stands and he was turning the tyre to see if the other tyre would spin, would you have to engage 4Lo before doing the test to see if the lokka is working ?

[@liamcooper5202]

The locker doesn't unlock because on the inside spins slower (more resistance) but because the outside tyre spins faster than the diff centre. This unloads the carry pin from the ratchet halves on either side of the pin. The mechanism works the same way as friction pack LSD where the power is transmitted into the diff centre through the carrier pin. The shape of the 'not so round' hole that the pin sits in dictates the clamping force of the ratchet half under load. This is why Shauno could spin the tyre while ol mate held the other. If Shauno had of spun the drive shaft instead it would have just bound the diff until ol mate let go and both tyres spun.

[@mattdavis5443]

quick question what happens when you are going up a hill and you need a lokka but you also need to turn will it disengage?

[@TheMuddyhilux]

They made a stuff up with describing how these work. Basically, with any drive to the diff, they're locked. If you roll along in 4wd, out of gear and then turn, the locker will disengage. As soon as you accelerate, the locker will lock.

[@stephenhilton9262]

TheMuddyHilux have played with many of these over the years , Detroit made one so did truetrack and many other slight variations of the same design ( many court cases happened 20 years ago ). Both wheels are locked till one wheel drives faster than crown wheel speed this allows the dog clutches ride over each other against the low spring pressure

[@lukebailey8054]

Great video, need more like it on different accessories

[@jasonfelstead6476]

I had these on a gen 1 4 runner with ifs front had them on back and front and they made a huge difference but i will say the rear one can be a bit annoying occasionally it would spool up and let go no damage just noise second when you do tight turns you will hear it clicking away but no big issue but i did find if you were a supermarket carpark making multiple turn it would start spooling up and making it jerky to drive This was when it was manual when i put a auto in this did not happen any more due to constant drive going to the diff in front no issues just huge gains :) I had these for about 5 years and a lot of four wheel driving and it was my daily even when i put v6 in no issue i would happly use these again and will in my mitsubishi mk triton.

[@4wdsystemsgeartogoannawher754]

Yes - you will hear it tock around corners - you may not hear it with windows up. Occasionally you will get a metallic clack out of it when you are accelerating heavily out of a tunr when it was unlockerd - its the two halves slapping together under load - doesnt do any damage. That can also happen if you have different rotating tyre diameters - eg different tyres, different pressures, flat tyre or different wear rates on the tyres (eg using an old worn spare).

[@SlayerA97]

when old mate holds the other wheel and he can spin the tire that just says to me its not gonna crawl up a large rock step, on that one side. A rock step that is putting the same rotational resistance on the wheel as the fella holding the wheel is not hard to find either so its like having an upgraded LSD and you will still need momentum to get over it but there are hardly any comparison videos on this topic and most manual locker comparison videos talk about their function of locking the diff and not against the auto lockers. it's all about your preference and valued performance but hey auto in the front manual in the back can still steer on a steep tricky track and get the best of both worlds that is my opinion.

[@partygamer99]

@@SlayerA97 your incorrect its doing that because there is no power to the wheels. when power is applied it puts pressure on a pin which pushes the lokka out causing it to lock i suggest u watch a video of how a auto lokka works. in saying that i still prefer a manual locker

[@partygamer99]

it works the opposite to a lsd when ever u put drive down it will lock unless the force of the wheel wanting to spin at a different rate to the other side out weighs the force from the driveshaft. an auto lokka will stay locked majority of the time. thats why u run a manual locker so u have full control of when its on and off

[@Fernweh4x4andadventure]

Curious as I just thought about it, what about “automatic traction control” how does that affect the lokka on the road?

[@k2svpete]

Traction control and lockers like this are actually a very good combination.

[@Fernweh4x4andadventure]

Peter Moore, sounds promising, but if you have the traction control on, whilst driving on the road (2019 triton and pathfinders) wouldn’t that damage the lokka? I imagine using “auto traction” in the rain on bitumen roads, what if you forget and your doing 80+ kilometres. Just curious

[@4wdsystemsgeartogoannawher754]

Seems to work on everything we've thrown at it. The traction control detects wheel spin (or rather a significant difference in wheel speed) to start workikg - The Lokka prevents that from happening in the first place - so it doesnt geta chane to work !

Awesome! Sounds like my next purchase, thanks for the reply!

[@kingkire1556]

I noticed it makes a clunking noise when Shaun demonstrates how it unlocks. So can you hear the clunking from inside the cab when disengaged?

[@antontaylor4530]

The "clunking" noise is the locker ratcheting. It makes that noise when you corner. The inside tyre is getting all of the power and the outside wheel is over-running the inside tyre. Whether or not you can hear it from inside depends on a number of things - how well it's set up, how chunky your axles are etc. If you set it up properly, it's not super noisy. If you have a tin can like my Samurai, you can really hear it even when it's set up right, if you drive a Land Cruiser with lots of sound deadening and thicker diff pumpkins, probably not so much. Probably...?

@@antontaylor4530 Hey man, I just realized that this type requires power steering otherwise you'll fight the steering wheel badly! Right?

[@antontaylor4530]

@ No, they behave like an open diff in that respect. I have a friend who has a samurai with the lockright version of these front and back, and he doesn't have power steering. Steers like stock.

[@QuintinKruse]

I understand that the outside wheel can freely spin faster in a corner, and so it works great when driving forwards. Will it work in reverse though?

[@einfelder8262]

Yes. I have one in my Patrol, and it works in reverse, with a BUT - it causes windup on full lock in reverse when reversing uphill with a lot of load, such as when multi-point turning on a switchback. Solution is to use less power if possible and use less steering lock. However, that maybe would not happen in a vehicle that is not centre diff locked (the Patrol does not have a centre diff but a fixed drive transfer case). Reversing without load not a problem. I believe that when on full lock in a vehicle with CV shafts they are most prone to damage whether Lokka'd or not, if too much power is applied.

[@JeremyPetho]

The operation of the locker reverses when you are reversing or engine braking, so it it works just as well in both directions.

[@4wdsystemsgeartogoannawher754]

Yes it does - everything is symmetrical, it also works in reverse principle too - few people are aware of this - so downhill engine descending is much better - you can no longer lock op the wheel in the air(or on scrabbly slippery ground) when feathering the brake to slow you down which causes the wheel on the ground to double its speed and literally accelerate you down the hill !

[@stephenhilton9262]

[@andrewpedersen5071]

@Graeme Yamaha you're wrong in a way. They can't disengage if you are hard on the throttle and turning, the tiny springs can't overcome the torque which you are applying. I use to have one in my rear diff and if you put your foot down the lokka would stay locked on. It's annoying that they didn't explain this in this video because that is why I'm sceptical of sticking one in my front diff, it may be hard to turn or break something if you have to be on the throttle hard and turn at the same time. I broke the lokka branded one that was fitted into a 80 series 9.5 inch rear diff. Broke where the springs sit in the casing and made it so it didn't lock anymore and would make a hell of a noise when turning. I replaced it with a brand called spartan as they had a much beefier spring and detent setup than the lokka.

[@andrewpedersen5071]

@Graeme Yamaha as I said, the one I broke was fitted into a ln65 hilux with 80 series diffs and a 350 chev motor, it was in the rear though not the front. Have to say I loved it, for the price it work really well. It drove really well on road too, when it was working correctly I couldn't even hear it and the vehicle drove normally. I have never driven one with a front auto locker though and in my mind I'm not so sure about fitting them to the front but in saying that I really need to experience it first before making a final judgement. In the rear though I think they are the best bang for buck you can get.

[@alexdevries7594]

Hi Steve - it DOES work while you're turning on a track. It only unlocks when the wheel speed for single wheel is GREATER than the input drive from your engine. For example, you're driving up a difficult track. Your engine is pushing you at 2m per second. You turn your wheels left. The lokka keeps driving your left wheel at 2m/s. Your right wheel (following the longer path) is pushed [by the ground] at 2.1m/s. So the lokka UNLOCKS and allws that wheel to travel faster. But it doesn't let it travel any slower than the engine speed (e.g. 2m/s) Does that make sense? Does it answer your question?

[@4wdsystemsgeartogoannawher754]

Yes - it will unlock if the track is firm, but if its wheel spinning due to power all the way then it would stay locked. It can change what its doing all the way up the track - so each part of the track might require different action and it can handle that. The front diff fitment is actually the best part of the Lokka design - its actually the best way of locking a vehicle because you still retain almost all of your steering but also get differential action when you need it

[@Steel6Strings]

The type of auto locker installed in that probably has replaced the side gears with the plates shown in the vehicle. For Suzukis, that setup doesn't like to unlock easy and can easily snap CVs/axles too. The alternative is to retain appropriate side gears which function the same as the plates, but ratchet more easily.
