Great Review. Thanks for a great insight into the options. I should have watched this before i entered blindly into buying a Harrop E-locker. my experience with Harrop E-locker is as follows. 1. They are a buggy and faulty item (a lot of dropped pins and mysterious "stuck locked" cases-(research for yourself before you buy) 2. Harrop customer care and warranty has to be the worst i have experienced as a consumer..They will blame anything with "could have been" "not defective" 3. My Harrop E-locker self locked on a freeway @90km/h (I have the fuse removed when not off-road) and not only destroyed the crown and pinion but also ripped out some of the front diff mounting on my ford Ranger. It was a horrific self destruction of a diff center that only ever had one off road engagement (just to try it) and under 1,500km since installation. 4. As the video shows the product isn't actually a locker unless you are moving forward they will unlock if you roll back (to adjust your approach.. which we all need to do) and will take ~1/2 a turn to re-lock ( how could this be called a locker?) It took Harrop more than a month to get back to me and refuse the warranty claim and they still haven't returned my diff back to me so i can have a mechanical engineer write a report. It has now been 2 months and i have had to purchase a new front diff assembly just to get the car back on the road. (I will be putting on an air locker as i will not do business with Harrop again) Please do your research and choose wisely
@@marshiano you were not the only one I made the same mistake. I could not find any useful information so thought I better make the video to hopefully save someone some coin and headache
I used to fit ARB lockers and can tell you they have quality issues. At the end I was dissassembling the locker and inspecting/cleaning the swarf from the units. TJM lockers are the best selectable locker on the market. E-Lockers are temperamental because of the way they lock and wiring in the housings actually move with the shaking which the housing goes through. I personally run a Lokka in the front of my part time 4x4 but nothing except the ramping type LSD in the rear. Im not into the crawling side of driving but I haven't been stuck without trying really hard.
Good video Stefan & I totally see your point. I just had soo many problems with my ARB air lockers that when I made the change (15 months ago) to the E-lockers it was almost magical, and haven’t had a problem in this time. But I can obviously see why you’ve changed.
yes mate, I hear you as well and I don't think E-Lockers are bad just not suitable for me, from my research it seems most people who have an issue with ARB's are because of poor installation and unfortunately I heard from a few people who had issues that they had them installed at ARB Francises which sometimes only have fitters...
Thank you for the explanation i was convinced that elockers were the go for my 200 but thanks to your informative video im now going the tjm pro locker.
It's called reverse rotation or high pinion. The southern hemisphere is reverse cut and rotates opposite of the northern hemisphere to make sure the earth doesn't spin off keep course and keep traction while rotating around the sun.
this is why one must have a Detroit locker in the rear. and never use the clutch while climbing. as you never "lose" the lock, and should never "roll: back. slide yes... but that is traction a different thing.
why would anyone be remotely interested in Eaton “lockers”, if they are providing no support when the trail gets technical? I guess they are for Californians who just want a neat part list for their truck… 4x4 guys know
My fj cruiser has factory fitted rear locker electronic type and up front an arb air locker. Never had any issues and was installed professionally by outback 4x4 Bayswater. I do some fairly rugged inclines with ruts and rocks and poke along quietly up them with lockers on. Never miss a beat very happy indeed. I think front and rear is the way to go and know when and how to use and not use them. Excellent video.
You seem to have closely analysed the merits of each diff lock. I tend to agree with you and your choice - however - this internal air line fracturing business is IMO due to the flexing of the diff housing. I have had experience with ARB diff locks and this has happened in a number of occasions over the years. It doeth shittith me to tears since when you need it most it fails! This is why i found you as i was wondering about electric activation as a means of negating this frankly unnaceptable internal airline BS. I now find the e Locker has a severe limitation. Look all we really need is an electric or cable dog clutch to stay in foward and reverse on a decent 4 pinion carrier. I ask why does it need to be this hard?
Great information, presented in an easily understood way, with what I thought to be a very balanced approach. Appreciate your efforts in making this video. Now I'm armed with some very relevant knowledge, I know which diff locker I'll be going with. Glen
One of the best locking differential is “OX” and I have it on my Dana 60 and there is nothing like it. It will luck instantaneously and will stay locked and going forward or rolling back will not effect the lucking mechanism and will not disengage. The only “O” ring is installed into the cover which operates the fork/piston and that O ring can take up to a 1000 PSI before it fails. It can be operated via cable shift, CO2 or air. www.ox-usa.com
didn't you know about ATB LSDs?! (auto torque balance LSDs) it's one of the torsen type LSD. it locks gradually from open to full lock without any buttons needed at any speed! suitable for both street & off roading. you can get it form these 2 best brands of this type of LSD, Wavetrac LSD & Quaife LSD. i wonder why OEMs did not adopt those in all cars!! dont tell me it's about reducing cost because what about making it as an option for costumers! 018
Not happy with my e locker at all. Northwest hill climbing were you have to back up and try again, the lock unlock mannerisms are a pain. Will switch to ox
Thank you I was surprised how the E lockers work for real, my mind of air lockers just changed very positively. I’ve never heard of the TJM lockers but I’m going to research them this afternoon so I have the best for my 4X4. Not going rock climbing or hot rock bouncing, I’m building a rig for serious bug out and for running the old roads on my maps of the 20’s- 30’s I’m metal detecting old schools an homesteads in the mountains just want an all around 4x4 to tackle going where no one in 50 yrs has driven.
It seems like this reviewer personally experienced the biggest drawback of all air-powered lockers, but still downplayed that enormous negative. He was left with no locker at all, due to an air line failure, as opposed to one that occasionally required a quarter-to-half-turn of a wheel before locking. I'll take the later.
hm, air line failures are easy to fix way easier than electrical issues, and I have seen plenty of people who had them with Harrop E-Lockers. Not to mention the many complete failures of Harrop Eaton E-lockers I have an image gallery of them where they take out the C/P and housing. I rather take an airline leaking than a complete failure.
Was just about to Pull the trigger on a Rear E-locker for My Dmax but rememebered this Vid so thought I'd rewatch it again just to be sure, but after going through the comments, I might save up the further $600 for a TJM Pro Locker, seems it'll save me money in the long run, Love your video mate and thanks for putting it together
My Gu Patrol it's ARB Airlockers fitted December 2001 , 21 years later there still going strong although the air compressor has been replaced 3 times... The Airlockers were factory fitted and have never missed a beat and the vehicles has played pretty hard over the years and 500.000 kms. I wouldn't worry about those "O" rings to much ! :)
@@AlloffroadAu I just bought a ARB locker for my 94 4runner, should I worry about the o-rings on the new design? Do they go bad more often than the old design?
Thx for the great and accurate review. I personally have a ARB locker fitted for 10years in my Lux. I recently had to change a leaking air seal on the locker. It was a unpleasant exercise for small problem. Thx again for the useful info.
its so annoying how tjm keep putting the copper air line over the crown wheel, we have been telling them that this is no good it can get torn open by the crown wheel but because every one at TJM are so knowledgeable no one ever listens to good advice.
corrugated road usage will course the copper pipe to come into contact with the crown wheel teeth in a short period of time coursing damage to the copper pipe, there is no need to put it over the top of the crown wheel when you can place it along side the carrier back face. the instruction book must have been written by some one from a mental asylum.
I love your accent and the way u talk lol. TJM is your recommendation for reliability and toughness for expedition? Your expert opinion is of great value
Unfortunately, because the OX locker requires a shifting mechanism to be mounted to the differential cover, the OX locker design is not compatible with Toyota (or any drop-out style) axles.
...bit of a shame that the Aussie made Maxi-Drive locker also wasn't included (vacuum operated); granted that they are only made for the Landrover / Rangie scene, I guess it is fairly limited.
Hi Have MaxiDrive lockers in Tiny and also had them in my 110. Best lockers in my opinion but not included as they are not made anymore for years so no way to purchase unless you buy a used one.
Just like any big purchase thorough research is needed, choose the wrong thing equals $3K or better mistake. None of these units are cheap, that’s including installation, I like the positive engagement of the pro- locker, however I never knew until now how all these functioned this was a very informative video.
Learnt something about the TJM, great in site, my question is, Is the TJM as indestructible as the ARB lockers.? I thought I was decided, now I have more questions. Cheers
I just had the seals fail on my rear ARB locker. It's three years old and the diffs have always been maintained etc. ARB are replacing under warranty (five year warranty) and they admit that they have had big problems with a third party supplier of bonded seals etc. But that isn't exactly comforting. They have designed a failure point whereby seals (third party of not) are failing. Time will tell.
I had a DYNATRAC 60 built with an ARB in 2001. It works flawlessly for 2 years... Then the air leaks internally started to happen. Went to OX with cable actuation and it has been just fantastic for years with zero problems
Unfortunately, because the OX locker requires a shifting mechanism to be mounted to the differential cover, the OX locker design is not compatible with Toyota (or any drop-out style) axles.
I ran an ARB Air Locker in my 1990 Toyota 4Runner (5 spd, 22r-e) for about 25 years of daily town driving, wildland travel and occasional technical four-wheeling. While the sound and vibration of the compressor took getting used to, it never failed. I would buy another for my current '05 4Runner without hesitation if I still drove in conditions where it would be helpful.
Do you find it a bit clunky. I used to run a lokka in the rear of my old hilux and whilst it worked well it was very noisy and clunky when turning. I presume they are a similar design.
even though lockers are just a bit down the road for me, this is exactly the info i'd like to get started. my '01 F150 has 422K+ miles on its oem IFS. adding a locker suggests i upgrade the ifs at the same time for robustness. as we all know, you aussies know best how to get the most from your offroading hardware, what kind of ifs do you suggest for an aging truck destined to do more offroad as she gets older?? Thx!!!
This video has just given me ammo for my warranty claim that has been denied by harrop. My locker does not engage anymore and they are claiming I turned it on while the wheels were spinning which damaged it. I told them I have only ever turned it on while stationary or going very slow with no load. This video shows the e locker disengages when going from drive to reverse and then from reverse to drive. The exact same situation that happens when you get bogged on the beach. You get stuck so you put it into reverse, then forward, then reverse etc. This situation is usually under high load as the wheels are stuck, the high load and change of direction unlocks and then re locks with high torque on the diff centre and was what put the force on the diff when the wheel re locked in. This is clearly how the damage has occured which is 100% a design fault. A locker is used to give extra traction but what's the point if it unlocks itself and then causes major damage to the diff?? I thought it may have been an electrical fault but obviously not Looks like my diff will getting fixed now under warranty after all!!
Didn’t think about that but yes you probably need to be careful when changing direction under load with elocker engaged like in sand or mud as that would engage and disengage locker under load which is not really advisable
@@AlloffroadAu I was never at any stage told about this unlocking stage on change of direction, I have never engaged my locker unless I was stopped or rolling straight forward slowly with no throttle however Harrop are accusing me of this and not covering the damage under warranty because of this. I bought a locker so I could have both wheels locked for maximum traction but the fact that it unlocks and re locks on change of direction is definitely a problem especially in a boggy sand condition however Harrop refuse to admit it as of yet. They claim the locker does not unlock on change of direction even though you can clearly see the locking pins sliding down the forward ramp to the unlocked position and then sliding up the reverse locking ramp and then re locking at the end of the ramp and in a situation where removing a car from being bogged requires forward and backwards driving under high load to rock a car out of the situation causes damage to the locker due to the design fault. They are clearly denying responsibility for the design issue to avoid future warranty issues. I will be getting an independent engineers report assessing the damage and how it occured and contacting consumer affairs in regards to this if harrop does not repair my locker.
yes, I can see how the locking mechanism of the e-locker under the circumstance you described could cause failure, if you reverse under load with the lockers engage Harrop says the locker will not disengage however I have seen different in many circumstances. If Harrop suggests to not engage and disengage under load I would think they would also need to say don't make reveres and forward changes under load if the locker is engaged. I like the electronic concept of the e-locker but the engagement mechanism is not well-thought through. If it's not warranted I would contact Fair Trading
Daine Batchelor mate dump them and go tjm. I’m on my 4th set of arb lockers in 87,000kms. The first failure was the air leak both front and rear after 21,000kms then a failure at 41,000kms that saw both front and rear diffs replaced and to top it of I had a catastrophic failure when a crown wheel bolt fell out at 87,000kms that destroyed the diff and housing and crown and pinion plus the locker itself. I’m biting the bullet and going tjm even though these new arb diffs and lockers will have clocked up 50kms and that’s from arb,s workshop to tjm,s workshop.
Good point Daine about sand or mud forwards/backwards driving dis-engagement/re-engagement & the Harrop E-locker design issue & damage, I was going to buy & fit the Harrop E-locker to the front diff of my Landcruiser VDJ79R but after reading your post I have ruled the Harrop E-locker out along with the ARB air locker.
Nice comparison, although it would be helpful "for newbies" to see the purchase price differences as well as installation cost differences. I agree - if you have the budget, TJM is the way to go.
yes prices do vary though quite a bit and change with time. Elocker is usually cheapest as install is quick and hence often promoted by workshops quick in and out money
Well for the weekend warrior/occasional off roading, the e-locker would be the way to go. But for the more dedicated people. Air lockers plus an air system that can also inflate your tires should be the setup you would want.
Great video fella, thanks. I knew from the onset there were differences. When I got my lockers, in my 2003 Hilux SR5, four years ago, I don't think I'd heard of the TJM locker, I was sold solely on the ARB. My mate told me about the 'E' locker, and having never gelled with the notion of a cable (such as the OX locker) I did most of my research around the ARB and the Eaton 'E'. As mentioned my preference was with the ARB, and it takes a lot for me to change my mind once I get set on something, however, once I found out that they required a seal inside the diff, and reading someone's write-up stating that they were a mechanic dealing with a lot of the ARBs, and saying "who would want to fill their diffs with compressed air? I mean 'seriously'"? I started to focus on the 'E' lockers. The notion, like you mentioned, that these things undid between forwards and reverse, really didn't sit well with me at all, and psychologically still don't, however, that's what I ended up going for (front and rear, very simple operation installed by myself a 'meat worker') and have not had a single problem with them. I'm 'only' a hunter, requiring four wheel drive to get me safely back up the odd track that I encounter, however, I've never noticed them unlock whilst I've been out there doing it. Perhaps I'd change my mind if I got into more serious 'technical' wheeling, I don't know, but I'm certainly not about to rip them out, for me, they're perfect. Thanks.
Great video. I have ARB in the front and rear of a Jeep TJ. So far I have had no problems. I Like the TJM Pro Locker design, the air line and piston can be replaced in the trail. Anything that can be repaired on the trail is worth having. Thanks for your videos
i was looking forward to putting an E locker in my next 4wd, but after learning this i think ill avoid it. iT does make you think, the TJM could be actuatated with an electric solaniod instead of air also?
thankds for the technical breakdown I am looking for a pair of lockers to go on either my patrol or my Isuzu trooper neither 4x4 is new they are both used as tractors to pull broken down vehicles back to the public road where they can then be put on the recovery truck and brought back to the garage I have previous experience of mechanical limited slip diffs but in the muddier fields the 2 4x4s could do with a little help( so locking diffs to the rescue )
What I would like to know about air locker is can moisture freeze in the line in below freezing temps. Like in North Central USA where temps can go to -30 F .
Wow!! I didn't know the Elocker actually had a temporary disengagement like that. That is some great info! I've been doing a lot of research myself and thankfully came across your video. Thank you!
Thank you. I was one of the many who didn't know about the disengagement of the e-locker with direction change and that it would take a .25 rotation to engage in the first place. This will defiantly play into my locker buying decision as I drive a manual transmission and it is difficult to avoid a bit of rocking back and forth over obstacles.
yes you were not alone and even with an auto you may have sometimes non-deliberate but often deliberate small movement in reverse so for me I rather bee in full control of my locker
Very good detailed Information. I don‘t have the posibility to do what you do and i never will, but i love all the details. Thanks for making al that stuff.
I have an e-locker as well. My Jeep has been to Moab many times and has done all but the crazy-hard trails (i.e. Pritchet Canyon) and has never once had a problem. I think the roll back issue is really no issue at all.
from what I have seen Moab is pretty straight forward driving not much realignment needed so the disengagement would not make much difference for very technical driving of big rock steps it definitely makes a difference.
@@AlloffroadAu Ahh that makes a bit more sense. I do take some tough trails but usually walk them just to make sure it is possible for my 80 series to get through plus I have never really done exceptionally tight turning or overly technical stuff. Cheers for the reply.
It be nice if the tjm pro locker one used a electronic actuator selonoid to angage a constant lock doesn't disengage instead of air to push lock forward that will be a improvement that will be more durable and reliable wont require air then either 😁👌👍
That's actually a very good idea. I wonder if the limitation is that they can't get a solenoid strong enough into the limited space. Could probably accomplish it using a small-ish servo motor as well.
The newest ox locker redesigned cable and setup is the way to go and you dont need to fork out more $ for a diff cover smart smart smartest thing I've ever done and for like 20-30 $ more you can get a manual locking piece just in case you ripped you cable out or some dumb shit that happens to real wheelers.🙂
Hello, I have a question, can you mount an e-locker to normal street car and drift with it, in locked mode? I am extremely curious and I didn't find a single video on the internet with someone using it like that, everyone just weld an open diff to drift.
ARB redesigned their air lockers. The older ones had o-rings that would wear out when the diff was unlocked and being driven on the road, resulting in blown out axle end seals, oil being pushed out by the air pressure when activated, ect. Definitely something to consider if purchasing a second hand one
I’ve had my ARB lockers front and rear since 2003 in an 80 landcruiser diesel manual. Both lockers leak oil out the pneumatic solenoid upon disengagement. It’s like a puff of oil vapour and my firewall is covered in diff oil. Ive had three diff rebuilds in the rear, often after rock crawling. The lockers used to shear bolt heads which then floated around the diff centre until they smashed into the crown wheel and pinion and that was always a horrible sound and experience. Then I got it modified with more bolts. The o rings are always worn and the elastomer loses elasticity over time.. It’s just not a durable design in my opinion and I’m a mechanical engineer for almost 20 years. Just waiting for the upcoming fourth diff rebuild 😬
Great review, thanks for putting this out there. Hopefully u don't get the hardheaded fanboys attacking u after you presented the facts in such a clear way. Some people are so invested in their views that they don't want to listen to pesky little things like facts, smh. It's hilarious that they were telling u that the lockers are different in Australia, really? Lol. Even though u are speaking from personal experience and the manufacturer actually verified what u said. Good job. You are not trying to tear any particular system down you are just presenting the facts. There are even more types of lockers you didn't cover, all of them have their advantages and disadvantages. it's up to us to educate ourselves on the different types and to get the one that is best suited for our particular situation.
seems to be a very good locker however not readily available in Australia and installation cost would be quite a bit higher than for any of the other 3 lockers.
AllOffroad 4x4 Adventures TV why would installation be more? It comes complete with a diff cover that can be used with cable, electric, or air. I have OX in my D60 F-350 97 7.3. Just ordered the OX for my rear 10.25. Never had any issues in 7 years on my D60 front.
the OX locker requires a shifting mechanism to be mounted to the differential cover, the OX locker design is not compatible with Toyota (or any drop-out style) axles, unfortunately.
Like many I thought these three would be similar in performance, I am going to put a front locker in my BT-50 and am now looking to TJM, can you advise me on whether there would be any improvement replacing the rear OEM locker with a TJM also? thanks for a very informative video...
Only problem with TJM is that they don’t cover many vehicles and brands. I’m not familiar with the BT50 factory locker but if it works would not see a need to replace it.
Another quality video stepan i thought of an e locker for my front diff before but since one of our fellow drivers in his disco had one installed and failed twice i have stuck to my auto lokka in the front only no air lines or switches and has been bloody awesome the only thing wrong with them they cant be switched of but they are a bit savage when first installed i would not put an auto lokka in the rear btw
I used to have an Ashcroft ATB in the Disco 2, liked it for 99% of applications but still was reactive so stuffed up a few rock climbs hence I changed to an Air Locker at the time
Thank you for all the work you put into this video. Fantastic review. It was professional and insightful. Explaining the clear differences between all three lockers. You have made my decision as a not so full on enthusiast to keep it simple.
Excellent and well explained video. I have an '05 Jeep TJ Rocky Mtn, and I'm looking to do more challenging off roading, will be getting either the TJM or ARB lockers with 32" BFG MT's.
my 79 cruiser came out standard with a Toyota factory locker...hasn't missed a beat since iv used it. in saying that the rear diff lock took awhile to engage because it was new but its pretty good now, my only bad remark about it is it wont engage without 4wd (H4 or L4) and its either: rear lock or front AND rear. I know 9/10 times if you want the front the rear should be engaged anyway but I like having full choice over a vehicles abilities. if I could pick or choose at the end of the day id still pick ARB Airlockers
Spot on review. It really comes down to your choice and what will work for your needs. In the end, failure of your locking diff, isn't an option. Awesome review!
Thanks Ben, It was awesome that we could use your footage, your excellent comparison video was the first one which made me aware of the disadvantages of the E-Locker
Like the vid and info but you did not provide vid footage of technical obstacle navigation with the TJM locker set. I would really appreciate an update with video footage please and thank you very much for your time, resources and testing!
Hi Stephan, good choice. I had tjm prolockers installed 7 years ago on my 105 landcruiser still work ok, little air leak somewhere, but still do their job. I did choose Tjm above Arb, also because Arb would not give me warranty with their lockers, because I run 35 inch tyres on my cruiser and Tjm did. Maybe Arb do now, I have not checked.
Much appreciation for your time, effort and willingness to do the research for OUR benefit...I am in the process of starting a long expedition throughout the western half of the country (United States) and I want to ensure that all my critical parts are of solid quality and durability. Again, thank you.
I have the stock LSD on the rear of my LWB Trooper and an Aussie Locker in the front. As it has 2/4 option the front doesn't affect handling but care is taken when in 4. Works great for me in the UK. I could buy a used trooper for the price of an ARB so, no argument. NO WIRES, NO TUBES, NO FAILING. As long as you remember not to abuse the half shafts.
How are your lockers going so far ? , any issues , lam thinking of going the tjm path also but rear only as that’s all they do for the 200 series ..cheers Mark.
Love your videos. Also about to pull the trigger on a TJM Pro (air) Locker for my 60 which I had decided a few years ago was the best option (but didn't have the funds), only to find out now you can't get them anymore. I called a few dealers and they didn't even seem to know themselves, so must be recent. I also heard parts issue but that doesn't make sense. Might have to go ARB but I really don't like the o-ring leaks you year so much about. This video just makes me want the TJM pro even more. Surely there is some stock lying around somewhere???
Good information, I wish the Grizzly or Detroit Locker was available for my Toyota 8.2 Diff. I have a Grizzly Locker in my Nissan and it has been flawless for over 30k miles now. Probably going to go Harrop for my Toyota 8.2 despite its minor disadvantages.
Just fitted a TJM Pro Locker to my rear diff after having originally wanting the e locker. Thanks for a great video and my installer reinforced my decision as he also agreed that its the best of the 3.
Damn I was all about the Harrop E-lockers, but now watching this knowing it might not work if u roll back is a no go for me. Cause I get myself into sketchy situations pretty often and I need my lockers to work when I need them to. Definitely getting an air locker now most likely Tjm... thanks for the insight.
Keep the vent on the diff itself clear, and clean lube and the O-rings will last many years. You MUST clean out all the air passages several times. I have seen crap in the passages and the 1st time you engage them, its fine, but when you disengage it, it spits the crap out and in between the o-rings. They do a nice job keeping them clean, but the surface is ground, and you have a good chance of getting some crap out of it. I ALWAYS get crap out of the copper tube. All that will end up in the o-rings. Surgical clean and you are good to go.
i know lsd's bit frowned on,,i know toyota lsd aint worth a pinch of shit,but i do know that ford,or u.s. lsd's work as they should.for extreme 4x4,2 lockers needed,for casual plus 4x4ing,seems a rear lsd front locker is the go.you can actually turn while having traction.unlike rear lockers.turn on turn off turn on turn off,me,i like detroit lockers.which you can get different springs for to unlock earlier,.no fail rate.no leads,no switches,no repairs,no probs.&,,,a damn site cheaper.!!!
Haven’t tried a Lokka but did you as ATB it was good in most cases but was still reactive so I prefer a full manual locker. Some like a Detroit can be a bit noisy and I rare cases lock up in a wrong spot.
An excellent explanation. I was looking to get either an ARB Air Locker or TJM Pro Locker in my new LC 200 series. I will now have the TJM Pro Locker installed.
The TJM Pro locker Is my dad's diff lock. Dad invented it 40 years ago. It used to be called the McNamara locker, he sold the design to TJM. just before he sold the design to TJM he rang up ARB and told them, "would they like to buy the design and call it the ARB locker 2 so they have no competition because TJM wants to buy it". But ARB said nahh not really. I bet they wish they bought the paintent off him now hahahha
@@AlloffroadAu TJM makes the pro locker all wrong. The pneumatic cylinder throws further than the locking ring and there is a few other mistakes they do when they're manufacture this Pro locker. we have told them over and over and over for the past 10 years what they're doing wrong and they keep making them wrong
all these large companies that make all this aftermarket stuff just don't care all they do is make this crap as quick as possible and try and get as much profit you tell them what would make it better what they're doing to make it wrong all this all that nobody ever listens. Corporations are disgusting
Every single time we fit a TJM Pro locker to a customer's diff we have to start modifying a brand new diff lock because they're made in correctly.the normal person wouldn't even pick up that they're made wrong. And would just fit them as they are. And then while in operation/diff locked it all jams up and where's out
@@differentials Can i get some TJM "fixed by McNamara" lockers from you? As I have finally got the wife onboard with forking out for lockers and this is my one chance to get them and I want it done right. In Tas btw so a fix and ship kind of thing.
Great info! My factory locker in mitsubishi challenger has started playing up so looking at drop-in options I found only harrop do a suitable one. Interesting your findings with the elocker and something I need to seriously consider as do alot of technical driving! cheers
Have any of you gentlemen tried OX brand lockers? According to a lot of off roaders these lockers are supposed to be the strongest most reliable lockers you can get. Maybe you can include them in your next comparison?
You won't hear much about Ox lockers because they are only made for American axles with a removable cover. But they are a good option if you have this type of axle.
TJM isn’t much better, like anywhere you get good and bad operators iguess. My TJM experience was fine till you completed the purchase then they didn’t want to know about you anymore.
Great video thanks. I've also watched the full filthy motorsport video. I'm far from an experienced off roader of my 80 series but to me it looks like TJM is the way to go. Having a compressor onboard is vital for tyres anyway, so I'll have it to do both. Cheers.
Great Review. Thanks for a great insight into the options.
I should have watched this before i entered blindly into buying a Harrop E-locker. my experience with Harrop E-locker is as follows.
1. They are a buggy and faulty item (a lot of dropped pins and mysterious "stuck locked" cases-(research for yourself before you buy)
2. Harrop customer care and warranty has to be the worst i have experienced as a consumer..They will blame anything with "could have been" "not defective"
3. My Harrop E-locker self locked on a freeway @90km/h (I have the fuse removed when not off-road) and not only destroyed the crown and pinion but also ripped out some of the front diff mounting on my ford Ranger. It was a horrific self destruction of a diff center that only ever had one off road engagement (just to try it) and under 1,500km since installation.
4. As the video shows the product isn't actually a locker unless you are moving forward they will unlock if you roll back (to adjust your approach.. which we all need to do) and will take ~1/2 a turn to re-lock ( how could this be called a locker?)
It took Harrop more than a month to get back to me and refuse the warranty claim and they still haven't returned my diff back to me so i can have a mechanical engineer write a report.
It has now been 2 months and i have had to purchase a new front diff assembly just to get the car back on the road. (I will be putting on an air locker as i will not do business with Harrop again)
Please do your research and choose wisely
Wow, thanks for sharing that is bad, I’m so glad I removed my ones again
AllOffroad 4x4 Adventures TV
Thanks for the pin.
Purchasing on The perception of quality and simplicity was my mistake.
@@marshiano you were not the only one I made the same mistake. I could not find any useful information so thought I better make the video to hopefully save someone some coin and headache
Sounds like you did a bad install
Forget the complexity check out OX locker. I’ve had an OX in a 60 since it was released for sale, in a F-350
I used to fit ARB lockers and can tell you they have quality issues. At the end I was dissassembling the locker and inspecting/cleaning the swarf from the units.
TJM lockers are the best selectable locker on the market.
E-Lockers are temperamental because of the way they lock and wiring in the housings actually move with the shaking which the housing goes through.
I personally run a Lokka in the front of my part time 4x4 but nothing except the ramping type LSD in the rear. Im not into the crawling side of driving but I haven't been stuck without trying really hard.
Good video Stefan & I totally see your point. I just had soo many problems with my ARB air lockers that when I made the change (15 months ago) to the E-lockers it was almost magical, and haven’t had a problem in this time. But I can obviously see why you’ve changed.
yes mate, I hear you as well and I don't think E-Lockers are bad just not suitable for me, from my research it seems most people who have an issue with ARB's are because of poor installation and unfortunately I heard from a few people who had issues that they had them installed at ARB Francises which sometimes only have fitters...
Thank you for the explanation i was convinced that elockers were the go for my 200 but thanks to your informative video im now going the tjm pro locker.
elockers do work differently in australia vs america, they work upside down
lol that's good one
It's called reverse rotation or high pinion. The southern hemisphere is reverse cut and rotates opposite of the northern hemisphere to make sure the earth doesn't spin off keep course and keep traction while rotating around the sun.
this is why one must have a Detroit locker in the rear. and never use the clutch while climbing. as you never "lose" the lock, and should never "roll: back. slide yes... but that is traction a different thing.
why would anyone be remotely interested in Eaton “lockers”, if they are providing no support when the trail gets technical? I guess they are for Californians who just want a neat part list for their truck… 4x4 guys know
My fj cruiser has factory fitted rear locker electronic type and up front an arb air locker. Never had any issues and was installed professionally by outback 4x4 Bayswater. I do some fairly rugged inclines with ruts and rocks and poke along quietly up them with lockers on. Never miss a beat very happy indeed. I think front and rear is the way to go and know when and how to use and not use them. Excellent video.
You seem to have closely analysed the merits of each diff lock.
I tend to agree with you and your choice - however - this internal air line fracturing business is IMO due to the flexing of the diff housing. I have had experience with ARB diff locks and this has happened in a number of occasions over the years. It doeth shittith me to tears since when you need it most it fails!
This is why i found you as i was wondering about electric activation as a means of negating this frankly unnaceptable internal airline BS.
I now find the e Locker has a severe limitation.
Look all we really need is an electric or cable dog clutch to stay in foward and reverse on a decent 4 pinion carrier.
I ask why does it need to be this hard?
Thanks for the time you've taken to put this together.
Me "Mate, A locker is a locker period!"
Me now - Boy was I wrong :/
Thank you for such an insightful review!
Thanks mate have to admit I thought the same until I started looking in to them closer.
Great information, presented in an easily understood way, with what I thought to be a very balanced approach. Appreciate your efforts in making this video. Now I'm armed with some very relevant knowledge, I know which diff locker I'll be going with.
Glen
Glad it was helpful!
One of the best locking differential is “OX” and I have it on my Dana 60 and there is nothing like it.
It will luck instantaneously and will stay locked and going forward or rolling back will not effect the lucking mechanism and will not disengage.
The only “O” ring is installed into the cover which operates the fork/piston and that O ring can take up to a 1000 PSI before it fails.
It can be operated via cable shift, CO2 or air.
www.ox-usa.com
Yes OX is great but not well known here in oz and a fair bit more expensive installation wise.
Look at the instructions for installation, it’s easier than any of these air lockers. Try again.
didn't you know about ATB LSDs?! (auto torque balance LSDs) it's one of the torsen type LSD. it locks gradually from open to full lock without any buttons needed at any speed! suitable for both street & off roading. you can get it form these 2 best brands of this type of LSD, Wavetrac LSD & Quaife LSD. i wonder why OEMs did not adopt those in all cars!! dont tell me it's about reducing cost because what about making it as an option for costumers! 018
yep had one. It's not bad for many cases but it can be a bit noisy and I like to have control over when I'm locked and not
Not happy with my e locker at all. Northwest hill climbing were you have to back up and try again, the lock unlock mannerisms are a pain. Will switch to ox
Thanks for the review! Filthy Motorsports is awesome too, love that channel.
Thank you I was surprised how the E lockers work for real, my mind of air lockers just changed very positively. I’ve never heard of the TJM lockers but I’m going to research them this afternoon so I have the best for my 4X4. Not going rock climbing or hot rock bouncing, I’m building a rig for serious bug out and for running the old roads on my maps of the 20’s- 30’s I’m metal detecting old schools an homesteads in the mountains just want an all around 4x4 to tackle going where no one in 50 yrs has driven.
couldn't TJM just use an electromagnet instead of air and eliminate the airlines etc?
What’s he best locker for the front diff?
It seems like this reviewer personally experienced the biggest drawback of all air-powered lockers, but still downplayed that enormous negative. He was left with no locker at all, due to an air line failure, as opposed to one that occasionally required a quarter-to-half-turn of a wheel before locking. I'll take the later.
hm, air line failures are easy to fix way easier than electrical issues, and I have seen plenty of people who had them with Harrop E-Lockers. Not to mention the many complete failures of Harrop Eaton E-lockers I have an image gallery of them where they take out the C/P and housing. I rather take an airline leaking than a complete failure.
Same as if the Elocker installer didn’t fasten the wire properly inside the housing and it got chewed up.
Literally every bit of information I was looking for. Superb video. Thanks so much
My pleasure 😊
Detroit locker and Torsen LSD no Airlines no electric lines always there always work.
Detroit in front .
Was just about to Pull the trigger on a Rear E-locker for My Dmax but rememebered this Vid so thought I'd rewatch it again just to be sure, but after going through the comments, I might save up the further $600 for a TJM Pro Locker, seems it'll save me money in the long run, Love your video mate and thanks for putting it together
Thank you very much.... Glad it helped.
Thanks Stefan......
We're in the process of putting front & rear lockers into our Wrangler JK.....
So, that's good info....
My Gu Patrol it's ARB Airlockers fitted December 2001 , 21 years later there still going strong although the air compressor has been replaced 3 times... The Airlockers were factory fitted and have never missed a beat and the vehicles has played pretty hard over the years and 500.000 kms. I wouldn't worry about those "O" rings to much ! :)
was a different design then mate o rings indeed where no issue in old design.
@@AlloffroadAu I just bought a ARB locker for my 94 4runner, should I worry about the o-rings on the new design? Do they go bad more often than the old design?
Same in my LC105. 20 years and no problems with my ARB Airlockers F & R, or the compressor.
Thx for the great and accurate review. I personally have a ARB locker fitted for 10years in my Lux. I recently had to change a leaking air seal on the locker. It was a unpleasant exercise for small problem. Thx again for the useful info.
I reckon 10 years is good, bit annoying is that you take whole diff out and a 10c part cost $700 in labour
AllOffroad 4x4 Adventures TV sounds way more expensive to maintain than an OX locker
its so annoying how tjm keep putting the copper air line over the crown wheel, we have been telling them that this is no good it can get torn open by the crown wheel but because every one at TJM are so knowledgeable no one ever listens to good advice.
you can drill a hole down the bearing cap bolt and put the copper air line down there, it is so so soooo much better than over the crown wheel.
corrugated road usage will course the copper pipe to come into contact with the crown wheel teeth in a short period of time coursing damage to the copper pipe, there is no need to put it over the top of the crown wheel when you can place it along side the carrier back face. the instruction book must have been written by some one from a mental asylum.
Hello, Neville yep got bumped during my install and chopped it to pieces. You would not be related to McNamara who developed the locker originally??
@@AlloffroadAu yes im his son, dad designed and patented the pro locker 20 years ago exactly how it is today.
@@differentials great tip will get that done when I re-gear diffs soon
I love your accent and the way u talk lol. TJM is your recommendation for reliability and toughness for expedition? Your expert opinion is of great value
yes TJM Pro Locker seems to be the best option...
I prefer ox lockers. No wires or air systems to fail. Even if the cable fails I can incert a bolt and lock it until I hit pavement again.
heard a lot of good things about the OX locker may need to try one on my next build
Unfortunately, because the OX locker requires a shifting mechanism to be mounted to the differential cover, the OX locker design is not compatible with Toyota (or any drop-out style) axles.
Got front and rear ARB air lockers in my 91/92 Swb Pajero.
Wanted them all my life,,,Very happy.!
...bit of a shame that the Aussie made Maxi-Drive locker also wasn't included (vacuum operated); granted that they are only made for the Landrover / Rangie scene, I guess it is fairly limited.
Hi Have MaxiDrive lockers in Tiny and also had them in my 110. Best lockers in my opinion but not included as they are not made anymore for years so no way to purchase unless you buy a used one.
hi there can you let me know were you get those front lights for the 100 series they look sweet
Just like any big purchase thorough research is needed, choose the wrong thing equals $3K or better mistake. None of these units are cheap, that’s including installation, I like the positive engagement of the pro- locker, however I never knew until now how all these functioned this was a very informative video.
Thank you very much....
Learnt something about the TJM, great in site, my question is,
Is the TJM as indestructible as the ARB lockers.? I thought I was decided, now I have more questions. Cheers
Haven’t had a issue with it on paper should be stronger then ARB
I just had the seals fail on my rear ARB locker. It's three years old and the diffs have always been maintained etc. ARB are replacing under warranty (five year warranty) and they admit that they have had big problems with a third party supplier of bonded seals etc. But that isn't exactly comforting. They have designed a failure point whereby seals (third party of not) are failing. Time will tell.
I had a DYNATRAC 60 built with an ARB in 2001. It works flawlessly for 2 years... Then the air leaks internally started to happen. Went to OX with cable actuation and it has been just fantastic for years with zero problems
Unfortunately, because the OX locker requires a shifting mechanism to be mounted to the differential cover, the OX locker design is not compatible with Toyota (or any drop-out style) axles.
I ran an ARB Air Locker in my 1990 Toyota 4Runner (5 spd, 22r-e) for about 25 years of daily town driving, wildland travel and occasional technical four-wheeling. While the sound and vibration of the compressor took getting used to, it never failed. I would buy another for my current '05 4Runner without hesitation if I still drove in conditions where it would be helpful.
Tjm pro locker 👍
what about the bullet proof lunch box locker 🙂
I have used the Detroit locker in the FORD 9 inch , on my 85 full-size BRONCO. Best dif lock on the planet
More of a unlocker but heard they work quite well
Do you find it a bit clunky. I used to run a lokka in the rear of my old hilux and whilst it worked well it was very noisy and clunky when turning. I presume they are a similar design.
11:36 When the air line broke in your diff did it blow gear oil out of your seals?
even though lockers are just a bit down the road for me, this is exactly the info i'd like to get started. my '01 F150 has 422K+ miles on its oem IFS. adding a locker suggests i upgrade the ifs at the same time for robustness. as we all know, you aussies know best how to get the most from your offroading hardware, what kind of ifs do you suggest for an aging truck destined to do more offroad as she gets older?? Thx!!!
I have OX lockers in my 97 F-350 7.3. Flawless operation for years!!!
This video has just given me ammo for my warranty claim that has been denied by harrop. My locker does not engage anymore and they are claiming I turned it on while the wheels were spinning which damaged it. I told them I have only ever turned it on while stationary or going very slow with no load. This video shows the e locker disengages when going from drive to reverse and then from reverse to drive. The exact same situation that happens when you get bogged on the beach. You get stuck so you put it into reverse, then forward, then reverse etc. This situation is usually under high load as the wheels are stuck, the high load and change of direction unlocks and then re locks with high torque on the diff centre and was what put the force on the diff when the wheel re locked in. This is clearly how the damage has occured which is 100% a design fault. A locker is used to give extra traction but what's the point if it unlocks itself and then causes major damage to the diff?? I thought it may have been an electrical fault but obviously not Looks like my diff will getting fixed now under warranty after all!!
Didn’t think about that but yes you probably need to be careful when changing direction under load with elocker engaged like in sand or mud as that would engage and disengage locker under load which is not really advisable
@@AlloffroadAu I was never at any stage told about this unlocking stage on change of direction, I have never engaged my locker unless I was stopped or rolling straight forward slowly with no throttle however Harrop are accusing me of this and not covering the damage under warranty because of this. I bought a locker so I could have both wheels locked for maximum traction but the fact that it unlocks and re locks on change of direction is definitely a problem especially in a boggy sand condition however Harrop refuse to admit it as of yet. They claim the locker does not unlock on change of direction even though you can clearly see the locking pins sliding down the forward ramp to the unlocked position and then sliding up the reverse locking ramp and then re locking at the end of the ramp and in a situation where removing a car from being bogged requires forward and backwards driving under high load to rock a car out of the situation causes damage to the locker due to the design fault. They are clearly denying responsibility for the design issue to avoid future warranty issues. I will be getting an independent engineers report assessing the damage and how it occured and contacting consumer affairs in regards to this if harrop does not repair my locker.
yes, I can see how the locking mechanism of the e-locker under the circumstance you described could cause failure, if you reverse under load with the lockers engage Harrop says the locker will not disengage however I have seen different in many circumstances. If Harrop suggests to not engage and disengage under load I would think they would also need to say don't make reveres and forward changes under load if the locker is engaged. I like the electronic concept of the e-locker but the engagement mechanism is not well-thought through. If it's not warranted I would contact Fair Trading
Daine Batchelor mate dump them and go tjm. I’m on my 4th set of arb lockers in 87,000kms. The first failure was the air leak both front and rear after 21,000kms then a failure at 41,000kms that saw both front and rear diffs replaced and to top it of I had a catastrophic failure when a crown wheel bolt fell out at 87,000kms that destroyed the diff and housing and crown and pinion plus the locker itself. I’m biting the bullet and going tjm even though these new arb diffs and lockers will have clocked up 50kms and that’s from arb,s workshop to tjm,s workshop.
Good point Daine about sand or mud forwards/backwards driving dis-engagement/re-engagement & the Harrop E-locker design issue & damage, I was going to buy & fit the Harrop E-locker to the front diff of my Landcruiser VDJ79R but after reading your post I have ruled the Harrop E-locker out along with the ARB air locker.
Nice comparison, although it would be helpful "for newbies" to see the purchase price differences as well as installation cost differences. I agree - if you have the budget, TJM is the way to go.
yes prices do vary though quite a bit and change with time. Elocker is usually cheapest as install is quick and hence often promoted by workshops quick in and out money
Well for the weekend warrior/occasional off roading, the e-locker would be the way to go. But for the more dedicated people. Air lockers plus an air system that can also inflate your tires should be the setup you would want.
thanks , so much for the great info, your advice is always very good and i think tjm is my choice also ive herd so many bad things about ARB lockers
Great video fella, thanks.
I knew from the onset there were differences. When I got my lockers, in my 2003 Hilux SR5, four years ago, I don't think I'd heard of the TJM locker, I was sold solely on the ARB. My mate told me about the 'E' locker, and having never gelled with the notion of a cable (such as the OX locker) I did most of my research around the ARB and the Eaton 'E'.
As mentioned my preference was with the ARB, and it takes a lot for me to change my mind once I get set on something, however, once I found out that they required a seal inside the diff, and reading someone's write-up stating that they were a mechanic dealing with a lot of the ARBs, and saying "who would want to fill their diffs with compressed air? I mean 'seriously'"? I started to focus on the 'E' lockers.
The notion, like you mentioned, that these things undid between forwards and reverse, really didn't sit well with me at all, and psychologically still don't, however, that's what I ended up going for (front and rear, very simple operation installed by myself a 'meat worker') and have not had a single problem with them. I'm 'only' a hunter, requiring four wheel drive to get me safely back up the odd track that I encounter, however, I've never noticed them unlock whilst I've been out there doing it. Perhaps I'd change my mind if I got into more serious 'technical' wheeling, I don't know, but I'm certainly not about to rip them out, for me, they're perfect. Thanks.
The Ox uses a cable, air, or electric. The cable is a push cable not a pull. I’ve had 7 years and over 80,000 miles of trouble free problems in my D60
Great video. I have ARB in the front and rear of a Jeep TJ. So far I have had no problems. I Like the TJM Pro Locker design, the air line and piston can be replaced in the trail. Anything that can be repaired on the trail is worth having.
Thanks for your videos
i was looking forward to putting an E locker in my next 4wd, but after learning this i think ill avoid it. iT does make you think, the TJM could be actuatated with an electric solaniod instead of air also?
Would be good to know more about factory lockers like Toyota
thankds for the technical breakdown I am looking for a pair of lockers to go on either my patrol or my Isuzu trooper neither 4x4 is new they are both used as tractors to pull broken down vehicles back to the public road where they can then be put on the recovery truck and brought back to the garage I have previous experience of mechanical limited slip diffs but in the muddier fields the 2 4x4s could do with a little help( so locking diffs to the rescue )
What I would like to know about air locker is can moisture freeze in the line in below freezing temps. Like in North Central USA where temps can go to -30 F .
Just have to keep that forward momentum lol.
Awesome video mate I was debating on the TJM or the Harrop locker but now this has helped make up my mind
Wow!! I didn't know the Elocker actually had a temporary disengagement like that. That is some great info! I've been doing a lot of research myself and thankfully came across your video. Thank you!
Glad I could help!
Thank you. I was one of the many who didn't know about the disengagement of the e-locker with direction change and that it would take a .25 rotation to engage in the first place. This will defiantly play into my locker buying decision as I drive a manual transmission and it is difficult to avoid a bit of rocking back and forth over obstacles.
yes you were not alone and even with an auto you may have sometimes non-deliberate but often deliberate small movement in reverse so for me I rather bee in full control of my locker
Trained, experienced techs to install in the USA is a huge problem. Probably half or more of the installers don't know what they are doing..
same here in Australia mostly fitters install them and that causes issue especially with ARB lockers
Very good detailed Information.
I don‘t have the posibility to do what you do and i never will, but i love all the details.
Thanks for making al that stuff.
Great one thank you for clearing that up now it’s a lot more understandable between the makes 👍🏻
Thank god i watched this. And thanks guys!! Im going to put lockers in my D40 as the limited slip is well and truely stuffed.
I have no issues with the E-locker unlocking but I also have an auto that prevents roll back.
the issue is there but you will only notice doing rock crawls reversing to line yourself up, most normal driving you wont notice.
I have an e-locker as well. My Jeep has been to Moab many times and has done all but the crazy-hard trails (i.e. Pritchet Canyon) and has never once had a problem. I think the roll back issue is really no issue at all.
from what I have seen Moab is pretty straight forward driving not much realignment needed so the disengagement would not make much difference for very technical driving of big rock steps it definitely makes a difference.
@@AlloffroadAu Ahh that makes a bit more sense. I do take some tough trails but usually walk them just to make sure it is possible for my 80 series to get through plus I have never really done exceptionally tight turning or overly technical stuff.
Cheers for the reply.
Arb air locker is the right choice
It be nice if the tjm pro locker one used a electronic actuator selonoid to angage a constant lock doesn't disengage instead of air to push lock forward that will be a improvement that will be more durable and reliable wont require air then either 😁👌👍
That's actually a very good idea. I wonder if the limitation is that they can't get a solenoid strong enough into the limited space. Could probably accomplish it using a small-ish servo motor as well.
Thanks your explanation helped me understand the differences between the lockers and i now know which locker is suitable for me, well done .
The newest ox locker redesigned cable and setup is the way to go and you dont need to fork out more $ for a diff cover smart smart smartest thing I've ever done and for like 20-30 $ more you can get a manual locking piece just in case you ripped you cable out or some dumb shit that happens to real wheelers.🙂
They make a very limited range though.
Hello, I have a question, can you mount an e-locker to normal street car and drift with it, in locked mode?
I am extremely curious and I didn't find a single video on the internet with someone using it like that, everyone just weld an open diff to drift.
You sure can mate, you can get them for some ford ute diffs and most toyota diffs.
ARB redesigned their air lockers. The older ones had o-rings that would wear out when the diff was unlocked and being driven on the road, resulting in blown out axle end seals, oil being pushed out by the air pressure when activated, ect. Definitely something to consider if purchasing a second hand one
Not that I know off, a friend of mine just had new set installed by ARB in December 2018 and they were leaking oil out the breather in January
I’ve had my ARB lockers front and rear since 2003 in an 80 landcruiser diesel manual. Both lockers leak oil out the pneumatic solenoid upon disengagement. It’s like a puff of oil vapour and my firewall is covered in diff oil.
Ive had three diff rebuilds in the rear, often after rock crawling. The lockers used to shear bolt heads which then floated around the diff centre until they smashed into the crown wheel and pinion and that was always a horrible sound and experience. Then I got it modified with more bolts.
The o rings are always worn and the elastomer loses elasticity over time.. It’s just not a durable design in my opinion and I’m a mechanical engineer for almost 20 years.
Just waiting for the upcoming fourth diff rebuild 😬
Great review, thanks for putting this out there. Hopefully u don't get the hardheaded fanboys attacking u after you presented the facts in such a clear way. Some people are so invested in their views that they don't want to listen to pesky little things like facts, smh. It's hilarious that they were telling u that the lockers are different in Australia, really? Lol. Even though u are speaking from personal experience and the manufacturer actually verified what u said. Good job. You are not trying to tear any particular system down you are just presenting the facts. There are even more types of lockers you didn't cover, all of them have their advantages and disadvantages. it's up to us to educate ourselves on the different types and to get the one that is best suited for our particular situation.
Honestly, I like the OX locker the best. No air, no volts needed
seems to be a very good locker however not readily available in Australia and installation cost would be quite a bit higher than for any of the other 3 lockers.
AllOffroad 4x4 Adventures TV why would installation be more? It comes complete with a diff cover that can be used with cable, electric, or air. I have OX in my D60 F-350 97 7.3. Just ordered the OX for my rear 10.25. Never had any issues in 7 years on my D60 front.
the OX locker requires a shifting mechanism to be mounted to the differential cover, the OX locker design is not compatible with Toyota (or any drop-out style) axles, unfortunately.
Like many I thought these three would be similar in performance, I am going to put a front locker in my BT-50 and am now looking to TJM, can you advise me on whether there would be any improvement replacing the rear OEM locker with a TJM also? thanks for a very informative video...
Only problem with TJM is that they don’t cover many vehicles and brands. I’m not familiar with the BT50 factory locker but if it works would not see a need to replace it.
Another quality video stepan i thought of an e locker for my front diff before but since one of our fellow drivers in his disco had one installed and failed twice i have stuck to my auto lokka in the front only no air lines or switches and has been bloody awesome the only thing wrong with them they cant be switched of but they are a bit savage when first installed i would not put an auto lokka in the rear btw
I used to have an Ashcroft ATB in the Disco 2, liked it for 99% of applications but still was reactive so stuffed up a few rock climbs hence I changed to an Air Locker at the time
Fantastic, exactly the video I was looking for
Glad I could help!
Ox all the way for me. I'm wondering why you don't mention them?
They are not readily available in Australia hence I did not include them.
Thank you for all the work you put into this video. Fantastic review.
It was professional and insightful. Explaining the clear differences between all three lockers.
You have made my decision as a not so full on enthusiast to keep it simple.
Glad it was helpful!
Excellent and well explained video. I have an '05 Jeep TJ Rocky Mtn, and I'm looking to do more challenging off roading, will be getting either the TJM or ARB lockers with 32" BFG MT's.
Glad it was helpful!
my 79 cruiser came out standard with a Toyota factory locker...hasn't missed a beat since iv used it. in saying that the rear diff lock took awhile to engage because it was new but its pretty good now, my only bad remark about it is it wont engage without 4wd (H4 or L4) and its either: rear lock or front AND rear. I know 9/10 times if you want the front the rear should be engaged anyway but I like having full choice over a vehicles abilities. if I could pick or choose at the end of the day id still pick ARB Airlockers
Toyota Factory Elocker is a very different design to Harrop Eaton does not have the issue Harrop has.
Spot on review. It really comes down to your choice and what will work for your needs. In the end, failure of your locking diff, isn't an option. Awesome review!
Thanks for sharing
Thanks for the comparo. Informative and non biased.
Thank you very much....
Very well explained, cheers!
Thanks Ben, It was awesome that we could use your footage, your excellent comparison video was the first one which made me aware of the disadvantages of the E-Locker
This is making me like my 3rd gen 4runner style locker a lot more
Like the vid and info but you did not provide vid footage of technical obstacle navigation with the TJM locker set. I would really appreciate an update with video footage please and thank you very much for your time, resources and testing!
Check out a my Chanel there are a few videos of doing harder tracks with the Cruiser
Hi Stephan, good choice. I had tjm prolockers installed 7 years ago on my 105 landcruiser
still work ok, little air leak somewhere, but still do their job. I did choose Tjm above Arb, also
because Arb would not give me warranty with their lockers, because I run 35 inch tyres on my cruiser and
Tjm did. Maybe Arb do now, I have not checked.
Much appreciation for your time, effort and willingness to do the research for OUR benefit...I am in the process of starting a long expedition throughout the western half of the country (United States) and I want to ensure that all my critical parts are of solid quality and durability. Again, thank you.
Sounds great mate enjoy your journey
I have the stock LSD on the rear of my LWB Trooper and an Aussie Locker in the front. As it has 2/4 option the front doesn't affect handling but care is taken when in 4. Works great for me in the UK. I could buy a used trooper for the price of an ARB so, no argument. NO WIRES, NO TUBES, NO FAILING. As long as you remember not to abuse the half shafts.
How are your lockers going so far ? , any issues , lam thinking of going the tjm path also but rear only as that’s all they do for the 200 series ..cheers Mark.
Lockers go well no issues whatsoever and they have been used a bit
Love your videos. Also about to pull the trigger on a TJM Pro (air) Locker for my 60 which I had decided a few years ago was the best option (but didn't have the funds), only to find out now you can't get them anymore. I called a few dealers and they didn't even seem to know themselves, so must be recent. I also heard parts issue but that doesn't make sense. Might have to go ARB but I really don't like the o-ring leaks you year so much about. This video just makes me want the TJM pro even more. Surely there is some stock lying around somewhere???
just get ARB installed and warranted by a good diff place and you should have no prong issues
Thanks for the time and effort you put into this comparison and video. It helped me make my choice of a necessity.
Thank you comments like this are appreciated
Good information, I wish the Grizzly or Detroit Locker was available for my Toyota 8.2 Diff. I have a Grizzly Locker in my Nissan and it has been flawless for over 30k miles now. Probably going to go Harrop for my Toyota 8.2 despite its minor disadvantages.
Just fitted a TJM Pro Locker to my rear diff after having originally wanting the e locker. Thanks for a great video and my installer reinforced my decision as he also agreed that its the best of the 3.
Great to hear!
Why not the existing vacuum pump in the vehicle as a form of air locker?
Damn I was all about the Harrop E-lockers, but now watching this knowing it might not work if u roll back is a no go for me. Cause I get myself into sketchy situations pretty often and I need my lockers to work when I need them to. Definitely getting an air locker now most likely Tjm... thanks for the insight.
Keep the vent on the diff itself clear, and clean lube and the O-rings will last many years.
You MUST clean out all the air passages several times.
I have seen crap in the passages and the 1st time you engage them, its fine, but when you disengage it, it spits the crap out and in between the o-rings.
They do a nice job keeping them clean, but the surface is ground, and you have a good chance of getting some crap out of it.
I ALWAYS get crap out of the copper tube.
All that will end up in the o-rings.
Surgical clean and you are good to go.
i know lsd's bit frowned on,,i know toyota lsd aint worth a pinch of shit,but i do know that ford,or u.s. lsd's work as they should.for extreme 4x4,2 lockers needed,for casual plus 4x4ing,seems a rear lsd front locker is the go.you can actually turn while having traction.unlike rear lockers.turn on turn off turn on turn off,me,i like detroit lockers.which you can get different springs for to unlock earlier,.no fail rate.no leads,no switches,no repairs,no probs.&,,,a damn site cheaper.!!!
And what do you think about auto locker like a brand from australia called Lokka?
Haven’t tried a Lokka but did you as ATB it was good in most cases but was still reactive so I prefer a full manual locker. Some like a Detroit can be a bit noisy and I rare cases lock up in a wrong spot.
An excellent explanation. I was looking to get either an ARB Air Locker or TJM Pro Locker in my new LC 200 series. I will now have the TJM Pro Locker installed.
Good choice! They have not let me down so far
Have a 200 also. How did it go?
Thank you for the time investment for making this video. It was very valuable.
You're very welcome!
The TJM Pro locker Is my dad's diff lock. Dad invented it 40 years ago. It used to be called the McNamara locker, he sold the design to TJM. just before he sold the design to TJM he rang up ARB and told them, "would they like to buy the design and call it the ARB locker 2 so they have no competition because TJM wants to buy it". But ARB said nahh not really. I bet they wish they bought the paintent off him now hahahha
Lol they should have bought it pity TJM does not do much with its locker.
@@AlloffroadAu TJM makes the pro locker all wrong. The pneumatic cylinder throws further than the locking ring and there is a few other mistakes they do when they're manufacture this Pro locker. we have told them over and over and over for the past 10 years what they're doing wrong and they keep making them wrong
all these large companies that make all this aftermarket stuff just don't care all they do is make this crap as quick as possible and try and get as much profit you tell them what would make it better what they're doing to make it wrong all this all that nobody ever listens. Corporations are disgusting
Every single time we fit a TJM Pro locker to a customer's diff we have to start modifying a brand new diff lock because they're made in correctly.the normal person wouldn't even pick up that they're made wrong. And would just fit them as they are. And then while in operation/diff locked it all jams up and where's out
@@differentials Can i get some TJM "fixed by McNamara" lockers from you? As I have finally got the wife onboard with forking out for lockers and this is my one chance to get them and I want it done right. In Tas btw so a fix and ship kind of thing.
Great info! My factory locker in mitsubishi challenger has started playing up so looking at drop-in options I found only harrop do a suitable one. Interesting your findings with the elocker and something I need to seriously consider as do alot of technical driving! cheers
Have any of you gentlemen tried OX brand lockers? According to a lot of off roaders these lockers are supposed to be the strongest most reliable lockers you can get. Maybe you can include them in your next comparison?
I have heard of them but never run them nor know anyone who has. It's not a readily available locker in Australia hence I did not include them.
You won't hear much about Ox lockers because they are only made for American axles with a removable cover.
But they are a good option if you have this type of axle.
I’ve had a D60 fo 7 years OX locker, absolutely a pleasure to own. No problems, I use the cable type. I just ordered one for my Ford 10.25 rear.
Stock Rear Locker on my FJ & I learned from this video Thanks
Thanks mate glad Video was of help
Swayed me towards the tjm locker , at the moment with my experience with ARB they can get stuffed , their customer service is terrible .
yep I feel you
TJM isn’t much better, like anywhere you get good and bad operators iguess. My TJM experience was fine till you completed the purchase then they didn’t want to know about you anymore.
Great video thanks. I've also watched the full filthy motorsport video. I'm far from an experienced off roader of my 80 series but to me it looks like TJM is the way to go. Having a compressor onboard is vital for tyres anyway, so I'll have it to do both. Cheers.
