[@colinsmith6340]

I have an auto-lokka in the front of my ZD30 D22 navara with manual locking hubs, and i can say that they are damn amazing. I have definitely noticed the stiffer steering when on higher traction surfaces, and in most cases, just backing off the power a bit helps immensely. You can even leave the hubs in and engage 2HI, and barely make a difference to steering, but on smooth surfaces you can sometimes hear them clicking. In saying that, they are mind blowing on soft sand, you can feel the vehicle clawing its way through instead of being pushed. Super easy to install. I think the most amazing thing though is with descents. With the lokka automatically engaged, you get both wheels braking forces even if one wheel is in the air, and descents are incredible more controlled. Without the lokka, if you lose traction on one front wheel it will more then likely spin faster as its being forced to spin via the transfer case, and the other wheel will lock up, causing a slide, as there is nothing actually forcing it to spin anymore, because the other side is in the air. That just doesn't happen with the front locker, and the control while on a gravel hill suprised the hell out of me. So yes definitely a vote for the autolokka. Yes, occasionally you will get the stiffer steering, and probably the most inconvenient time will be when you are about to go around a corner, but if you let your foot off, its fine. As for front/rear, scientificly, its a hard choice. I mean, LSDs are already in rears, so a locker would also help more. But in saying that, the front locker on an IFS vehicle is a no brainer. With a rear LSD already helping, the front locker works well with IFS's lack of traction. The way i think of it is this: going up hill, most of the power and center of gravity would be over the rear wheels, so those two wheels will more then likely ALWAYS be on the ground. Like jocko said, once you have one of the front wheels are in the air, you now have a 2wd vehicle. A front locker will at least give you a 3wd vehicle. A rear locker would not. You see this in never every clip here in this video, its usually one of the front wheels in the air. Hell its probably 90 percent of the time, you have a front wheel in the air. Once a front wheel is in the air, the entire front becomes useless. 3wd vs 2wd. In the case of ute with more weight on the front due to the engine, and an empty tray, your two front wheels will spend more time on the ground, and with the rear LSD already helping, giving you a rough "2.5wd" a front locker would go back to give you 3.5wd. That, and with the front locker helping prevent one wheel from spinning wildly, and then when hitting the ground it causes the CVs to snap, you simply dont have that issue anymore, and there is no need to "Send" it as hard, also make the case for a front locker first. I also see a lot more failed front diffs in utes all for the same reason. Going up a hill, front wheels go up in the air, come back down, and pieces of money fall out of the diff. So yes. i work on the principle - whatever wheels you see spin the most up in the air, they are the ones you should put a locker onto. See a wheel spinnin? lock it up!

For a street/trail rig, I really like the combo of an aggressive limited slip e.g. worm gear type TrueTrack for the rear and an air locker for the front.

[@fatmanoverlanding]

Good one Jacko 👍 For my 80, I'm planning to put a front locker first. With the type of driving I do, if I only fit a rear locker, this can increase more front wheel lifts and potentially cause a flip (torque front wheel lifts) as it pushes the vehicle up obstacles. Front lockers prevents this as it pulls the vehicle up and over obstacles. But will eventually fit both.

[@emikearizona]

That's a very good point, thank you. You alone helped me decide which to do 1st

[@trickster8635]

Keep in mind that you will lose steering ability with a front selectable lock. Especially so when weight has transferred onto front axle, ie driving down a rutted step. Front locker great at holding back vehicle on steep, loose downhills, at the expensive of steering.

[@rockie307]

When going up hill the weight shifts to the back rear locker will do more good more often. I would get rear first then front.

"Jocko's Toolbox" should be a regular segment. Honestly Jocko the enthusiasm you show when you are explaining the technical aspects of things is amazing! I have a 2011 Amarok equipped with a factory electric rear locker, if I was looking towards getting a front locker down the track, would it be worth converting the rear to an air locker if I was going to put an air locker(including compressor and all other needed bits) in the front? Can E locker rear and Air locker front work together or would it be a smarter option to have them both the same? Cheers

I am first time watcher and if your still around i hope cause its been 2 years since this video i want to tell you thank you so much! I have been wanting to find out about the different locking situations and you did it great and humbly with no cockyness and i truly preciate that buddy. I have two 4x4s. Both from factory have limited slip rears and full time lock in front. Both are old 4x4s but great trucks. So when i fill like i dont need both lockers in front i just put them back in 2x4 and then i have limited slip rear and single tire pull front only difference in mine and yalls is yall have a real nice fancy switch that would be so convenient and i have a manual shifter i have to pull but it works. One of mine is a w 1994 Dodge Ram 2500 5.2 motor 5 speed manual looks brand new. Single cab. The other 1988 GMC ext cab K2500 with 1992 Chevy Tahoe 350 motor and a 4 speed Chevy Bulldog manual transmission. Great trucks. 88 dont look pretty but drive train is great. But it takes 40 acres to turn it around thats the only fall back with it. But i realy preciate your help but also not just talk but you did a out on trail illustration and so we cant ask for anything more than that. By what you showed and taught me i believe im good but i am always eager to learn and i sure got a whole lot to learn. Take care buddy and thanks again!

Got an TD5 and I put ann Ashcroft ATB Limited SLip Differential in both axels. It´s more of an overlander and the fact that it always provides best traction even on dirt roads was important for me. Plus the TD5 got a traction control, so even when one wheel should spin it will be stopped and the wheel with traction gets some force. Very happy with that setup, it´s simple, it works and it holds up.

[@Vacublaster1]

I have an auto locker in the front of my 4WD mainly due to budget, having said that I will be installing an air locker in the rear later this year. With regards to the auto locker in the front, it isn't an issue in the front when on the road, just unlock the hubs and the locker isn't even engaged. When in 4WD with the hubs locked, the locker is noisy but it's not something you don't get used to. If you shift out of 4WD, then the locker is not engaged any longer and there is no noise. The only disadvantage with an auto locker is you can't use 4WD without it being engaged whereas an e or an air locker can be disengaged. Steering is compromised a little with an auto locker but it isn't that bad which is the advantage of the auto locker over the other two.

[@iconiic1234]

A well done and fair comparison of lockers. My personal preference is rear first, unless it's IFS or like a Patrol with a solid LSD in the back. It may be worth mentioning too that some e-lockers can temporarily unlock when you change direction e.g. you reverse a little to take another go at climbing, which can make technical driving more difficult at times. For those interested AllOffroad 4x4 Adventures TV, Filthy Motorsports and other KZbin channels do a good job of explaining it.

[@jocko4wd281]

I went for a rear e-locker in the mighty Maximus. Purely and simply because I didn't know where I could reasonably fit an air compressor in the setup that I had. It has evolved slightly since then, but I'm sticking with the e-locker, and I'm considering putting one up front as well.

It's certainly a "depends on your driving" type of answer. Rock crawling, a front locker comes into its own but for most people, the rear is the most useful. I've a Discovery 2 with air lockers at both ends. The rear gets more use but having both is excellent.

[@mrjackt-4wdtouringinwester769]

Live axle front and rear, rear air locker first. IFS with open diffs, rear locker first. Any vehicle with a strong rear LSD (and honestly, this is only Patrols), front locker first. My Ol’ Jackaroo had a strong rear LSD, so it got a front air locker. My current MQ Triton (GLX poverty pack) had no lockers. It got a rear first, then a front. Twin air (or “e”) lockers always ultimate. The early “Pony” videos with twin auto lockers and shit small road tyres, proved how dramatic an improvement lockers make.

Considering the $ spent on mods, the budget issue is really out the window. Nobody seems to think twice about fitting a front bar but they cost twice what a locker does fitted.

[@texnorthman]

Great video! Just to be a pedantic sod: An open diff gives you a 50/50 torque split (roughly, not taking any internal resistance into account here). If one wheel is in the air i can't take any torque, so the wheel on the ground gets the same low/zero amount of torque. A locked diff just locks the axles, so it is no longer responsible for the torque distribution ratio, that job is left to the available grip. If both wheels have the same amount of grip, 50/50 split, if one wheel is on the ground, and one wheel is in the air, that's a 100/0 split. That doesn't change any of your practical advice and conclusions mind you, I just happened to have nerded out on locking/limited slip/torsen diffs a while back.

Front air locker is my personal preference because I own patrols and both my patrols have really good tight rear diffs and when I am off road the lack of front traction is where I get hung up so I would chose front air locker personal as it would suit me and my driveing/vehicle.

I find the argument for the front makes the most sense

[@Chris_the_Muso]

I had a Hilux with a Detroit (auto) locker in the rear. It was absolutely bullet proof and I drove that thing every where for about fifteen years, it was unbreakable. The advantage of an auto locker on the rear is that it comes into play whenever it is required, even on (for example) a building site or a mud puddle where you didn't think it would be needed. Yes, to get the front up sometimes you have to bounce the front wheels up onto a step, after which you are home free. A mate had a later model Hilux and he elected to put a Lock Right (also auto) soft locker on the front. The soft locker is better on the front because it does allow for more steering ability when it has to, however if the diff was locked he had very little ability to steer in soft sand when going slow. Having said that, If you do a lot of soft sand then you might be better with a soft locker on the front because when it comes to soft sand, pulling is actually better than pushing (ploughing) the front wheels. So, rear for dirt terrain that isn't too soft, front for sand and mush. Obviously, having both is ideal if you can afford it. If you are going to get both anyway then air lockers are about the same price but if you only get one then an auto locker will be cheaper (because of the cost of the compressor and installation). I can recommend the two brands I mentioned for reliability, I don't have any experience with any of the others. The Detroit locker requires professional installation because the setup of the dog clutch is spring loaded, and it can remove fingers if you don't know what you are doing. I believe the Lock Right can be installed by anyone if you follow the instructions, but my mate got his installed too. The only stuff that caused me any real trouble was trying to get up a steep soft sand dune or hill unloaded. The Hilux is quite light on the rear end, so even with the Detroit locker it was not sufficient to plough the front wheels up a soft sand hill. It worked better with a few hundred extra kilos over the rear axle in that case.

I like an auto locker in the rear with a selectable locker up front. I always do the rear first.

[@The_Opinion_of_Matt]

Lockers I prefer in order: 1) Factory installed selectable lockers 2) ARB Air lockers I don't currently own a vehicle with a locker. My 2009 VW GTI had a automatic e-locker from the factory. I removed it and installed a Peloquin Torque Biasing LSD (works like a Quaiffe)

Very good informative video. Thanks joko. I put an auto lokka in first up the front and then 12months later an E lokka in the rear. Its in an older ifs hilux, and both lokkas were needed as flex is very poor. Its a little mountain goat now.. So i would strongly suggest for ifs rigs get both..

Looking at pure traction gain, maybe a front locker in some situations can give you a bit more traction, but the overall convenience of a rear locker is far superior in my opinion: - rear axles are stronger and can handle with much less fear the offroad abuses with locker engaged - rear locker affects in a very limited and very predictable way the steering of your car (understeer) and when uphill it will always try to put the car in the correct maximum slope line, while front locker can unpredictably push your whole front end to the side of the tire with best traction, at risk of putting you in unpleasant situations. - while the rear locker can be engaged at any time you are in doubt you can need extra traction, front locker shall be used wisely, to avoid side effects. - if you have to climb and make a turn simultaneosly, you can left your rear locker engaged with no fear, while if you have only a single front locker, you must climb that hill unlocked, otherwise you've no chance to turn and decide your line ...

Hi jock, thanks you have talked me in getting a locker in the back as l don't do the large rock climbing but some rough steep country, cheers.

As a member if the Subaru 4wd club Victoria I don't normally do hard core driving although I have done some short stuff by myself, I went for the front auto lokka, will go rear whn I can afford it, and found it makes it easier even on the less challenging tracks, I had a rear on my old 80 series and I believe the front made the bigger difference

When are we going to see Rocket Rod again?

such a great video, I've been binge-watching 4x4 diff videos and this is one of my favorites my takeaway: I'm so fucking lucky that my 4Runner came stock with a Rear Locker, but the full Front & Rear Locker setup is still DEFINITELY the dream. Already have my ARB Twin air compressor mounted underhood, so 99% sure I'd go ARB Air Locker in front with the factory Toyota locker in rear. Current goal - still need modestly-bigger tires + modest lift/suspension upgrade. Then, front bumper + electric winch (tho I do already carry a beastly manual come-along winch for sheer emergencies) After that, saving up for a combined front locker + regearing install, since I'm told you might as well do both at the same time to avoid opening it up twice. Again, great info all around.

Steering... A front locker only affects steering on a high traction surface. Mine can be switched independently as Jocko’s can. On a low traction surface where there is a lot of wheel slip, a front locker helps. Point the front wheels where you want to go and locked front wheels pull where they’re pointing. Rear locked can only push straight and with both engaged, rear can sometimes oppose the front in corners. Front locked, rear unlocked in a turn on low traction surface allows the open rear differential action to assist the front around a corner. Ultimately, being able to independently select front or rear or both is the best arrangement for driver selectable lockers.

This is why I love my FJ cruiser! A-Track!! + Rear locker from factory. I am surprised they did not mention offroad traction control systems.

[@jackfourbee3609]

Love it. Great advice. Put it in the rear first.

[@Jack-ns5mn]

Solid locker in the rear like OX or ARB Air and Torsen type in the front to save breaking U joints and gears.

[@member369240sx]

Rear Locker ARB is what i fited first on my JKU. 2 reasons 1 offroading...the other is Snow roads here in Austria when its just not needed for 4wd but you dont want to one leg spin off of every light

[@nawaazsunnooman4752]

Nice informative video Jock! Thanks mate! well, for me the very best would be twin locked air compressor, as you make your vehicle crawl obstacles hence having less risk of damaging your rig. My request would be if you could do a video about the tire system which is used on the 6x6 mercedes focusing specially on how did they wire the air to the tires. That we be aswesome! Once again, nice vid mate!

[@tufftrails]

Thank you, that was probably the best vid on lockers I've seen. "new subscriber"...

[@mleah1978]

Been running a welded front with manual hubs for 2 years and I love it. Cost me nothing

[@blokebeershed7651]

I wanted to do a weldy for a while, just sometimes feel its abit dodgy😂

[@jdc_nz8386]

Allways wanted to know if that worked now I know I guess 😂

[@bradhaines1905]

For a budget bush rig a welded front is a must! If you get into a tight situation its as simple as unlocking a hub. I welded the front of my old gq and loved it. Theres a good chance ill be doing it to my gu now aswell
