It's nice to listen to a manufacturers rep that knows exactly what they are talking about. You should do more of those factory visits; winches, recovery gear, tents, axles, lights, etc.
That guy is wrong about the 100psi in a little line makes it 600psi. A 100psi in a 2” line vs a 1/4” is still a 100psi. The velocity (speed) of the air moves faster in a smaller line. Bernoulli's theorem says that there should be a reduction in pressure when the area is reduced. ... The narrower the pipe, the higher the velocity and the greater the pressure drop.
As you said, the pressure remains the same, it is the force that drops. 100psi across 1 square inch is 100 pounds of force, but that same 100psi across a half square inch is 50 pounds of force, but it will move twice as fast.
JKL is correct, 100PSI inside a dirigible ( if you could ever inflate it that high w/o an explosion ) would be the same as the inside of a portable air carry can in your 4x4. PSI is PSI, its absolute, not a volume relative measurement.
@@frontiergeek4953 Would you mind taking the time to explain what effect this has in relation to what the guy in the video said? Is he just incorrectly describing an actual change in performance or is there no difference?
@@EoWKen As JKL said, its still 100 PSI, but due to the small size line the air velocity is much higher, meaning its got the same push behind it (pressure) but the speed of the air is faster. It locks fast because of the velocity of the air. The ARB guy is trying to explain why its so quick but got the why wrong
For about $1k less then an ARB air locker I had an OX cable activated locker with the electrical solenoid option installed - push button activation convince - immediate action! NO air leeks to chase down - no differential tear down for an air leak.
Had the issue he talks about at 13:00 with my "Professionally installed" ARB in the 8.8 in my TJ. Only instead of leaking, the seal housing spun around on the bearing journal and the copper line was chewed up by the ring gear. Twice. Got on the phone with ARB USA and they sent me a new seal housing for free. (~$100 part. Awesome customer service!) Ordered an install kit, and set the differential up myself. Ended up with .060" more shim than the "professional" did when they set it up.
I’ve had an ARB in my rear D44 for 10 years. Works without fail. Disconnects instantly. Been living in Utah for 6 years and needed a front locker to be able to wheel on the more advanced trails out here. Could not afford another ARB D30. Bought a Yukon Zip locker and never looked back. Operates just as well as ARB and is supposed to be as bulletproof as the ARB for $200 less.
LOVE ARB...My TJ has their products.,..My 4 year old compressor for my lockers failed... Took it apart and found the fail point. I sent ARB a message with a video of my issue to see if they have a rebuild kit for sale and they said I was out of warranty by several years....so they sent me a new motor and it was at my house in 3 days...LOVE ARB..Best costumer service I have experienced in forever and in the USA based in Auburn, WA USA
Absolutely hated my ARB lockers. The front was broke all the time with a 44 in a TJ. The rear was ok just had problems with air leaks. I could never count on making it out of a trail so I did Eaton e-locks. Posi in the rear and open in the front when they are not locked and loved them so much that I have replaced them in all three of my TJs.
Oh boy , have I had some heated debates over this one...... The biggest issue with the ARB is that the lockers just like all of the tools you have on board , you come to depend on. You run trails based on capability and the tools you brought to get through. That ARB simply isnt going to be there every time. Everyone go ahead and pile on but its not . Ive been there and had to drag a truck that was perfectly capable on its own before the compressor laid down , or an O ring went out , or a line went . Take your pick I have seen most of them happen. Now I have run some hairy shit , I have gone up Thompson hill dragging another very loaded truck behind me and I can tell you . When this locker fiasco hits you . It then strains everyone elses equipment getting you through. Is anything perfect ? God no.... Does a Detroit solve this ? Yes and no . When you break an axle it takes the locker with it. Its not a nice to drive as an ARB locked truck . I can go down a laundry list of things on the detroit and I have a few hundred thousand miles behind me driving Detroit locked trucks . Now I am not downing the ARB lockers. Shit breaks in this environment period. I am only saying that yes , the ARB does and will fail. Ive not seen one to date that the actual diff failed its always the control system . So prepare for that..... Sorry ARB guy , its just the truth.. Also , this argument about having to stop or whatever ? Yeah that went right by me . So you gotta stop ? I am not sure why that is an issue exactly... So you stop and do what you have to do then go again....A train of trucks off road is one of the hardest things to keep moving on the planet . mouths are running people gotta pee and its a giant social gathering.....
Awesome video....showing the break down of how the locker works....helps alot of people understand....Brittany (orphice/try not laughing....lol)🤣.....Kevin keep it up💪.......Jelly was sooooo tired 🐶...can't wait till your next video....Safe travels
Probably one of your most useful and informative videos. Nice to hear an expert on this product, especially ARB Lockers. Obviously he is well informed....Thank you...
Wish Scott would come to Australia and train one of the private owned franchise owned centres especially the one in Brisbane south east as they really lack the expertise on this topic. My experience was an absolute shocker that took 18 months to resolve due to the assembly of the locker not done correctly by the Melbourne factory. The franchise store refused to open it up and look to see what the issue was instead where happy to blame other factors which did not exist. Vehicle was only a year old. They promised a replacement but that never happened. After 16 months of complaining I eventually got the Corporate owned ARB centre to look at it. The tech at this centre was absolutely brilliant. They simply did what should have been done in the first place and opened the locker up to find that the tension spring had been installed the wrong way around and had jammed the locking cogg, so simple. They fixed it and also had to replace the front axle which had a badly damage spline. Lockers have been running well, no complaints. Just won’t get my new vehicle done at a franchise store. Highly recommend the product just go through the ARB corporate centres.
Don't get wheel speed when the ARB isn't locked. The spiders will weld together because the pin is the weak point in this locker and you'll have to torch it out. Was a 600$ mistake that left my jeep down for 2 weeks due to Australia based ARB parts shipping. Much more if you don't know how to set up lockers/diffs. Keep em locked and they're super strong tho. Only other issue is the seals go bad, commonly around year 3, and you will not have a locker anymore. Other than that if you've got the money they work great. I might be trying eaton elockers next time around though.
Everyone I wheel with that has ARBs has had issues. Typically they leak internally and pressurize the housing. When they fail to make obstacles, first diagnostic is to turn off the engine and listen to see if you can hear the hiss of the leaking ARB. I have a eaton e-locker in the front and on time the wires rubbed and starting blowing fuses. Took some finding. My Detroit in the rear has never let me down.
@@jdsrcs8061 Absolutely. I should have added, some of those people were professionals, not home gamers like myself. Postmortems by those professionals have indicated issues with the internals seals more than the lines run the by the installer. At any rate, having watched it all go down multiple times, I will be avoiding air lockers unless the manufacturers stop blaming the users/installers and fix their design.
I worked for a shop that sold and installed a fair amount of arb lockers, we never had a issue. I have a arb in my rig that I've had forever. It's never had an issue. The owner of the shop also had multiple vehicles with arb lockers and never has had an issue except maybe a bad solenoid once. But we always installed magnet plugs in all our our diffs to reduce floating metal debris which also lengthens the life of the differential over all and is a cheap thing to do.
This is one of the many reasons I love your channel. ARB is simple smart, perfect for the rough necks driving these rigs. You guys are helping so many subscribers with basic offroad engineering and tips, add E3 offroad to your setup and your set. Fyi, I saw a sweet rig with a Lite Brite sticker on it yesterday. That is the first thing I look for when I see a sweet crawler. Anyways, love you guys and your family's, be safe. 👍🤙
Lol very cool video..while Iam force to practice social distance, you guys are chilling and having an amazing times..thank you for giving up relaxing content and thank you for sharing your life adventure to us
Well that was cool, didn't tell is what happened to the one that quit in the other video but I will have to go back find that guys RU-vid channel and find out what he found.
Great video. It was good to see how they work. I was always nervous about them because I guess I never really understood how arb lockers work. Thanks great video
Knowing what you know now, after building the Step Child and the Foster Child, if you were going to buy a Jeep and build it with Dynatrac 80's and 60's and ARB lockers and such, would you just buy a Sport S or a Sahara as the base?
If you're going to change/ build it anyways (voiding warranties) I'd recommend just looking for a non salvage titled fender bender, maintenance screwup, lemon law (of the going to be changed parts/ something you wouldn't mind upgrading,) flooded (if early & willing to put in the work,) etc. Then just build it from there
Lite Brite I know exactly what your talking about. Often my JL takes about a minute to unlock or lock. I wonder if its because the tires are not moving the same speed?
Fit Pro even the arb doesn’t lock up anytime you hit the switch, as u see in the video, your wheels have to move and the spider gear has to line up with the locker engagement ring. The Elockers are same way. If you’re in a stand still usually it’s harder to lock because chances are the gears don’t line up. But if you move your vehicle wheels half a turn, it’ll lock or unlock easy. Arb is basically same way, but it takes less wheel movement to lock up than elockers typically because they’re designed differently on how they lock. Watch how an elocker works, and it takes more movement for elock than the arb.
My '05 LJR had both factory lockers fail and have been replaced. Once you get into larger tire sizes (37+) and traction situations, they will be more likely to fail.
@@shadow9600 Ours have served us well with 37" tires for over a year now, BUT, we do have the ARB compressor kit on the way, so if they do fail we're prepared for the swap.
Ozzie Ozzie Ozzie Oie Oie Oie. Thanks for a real explain, so much clearer on the benefits now. Air is the future (for my ute any way). Again thank you. Nice to see the instore backdrop at ARB shows pride in its roots, didn't even black out the NSW or SA plates. Respect.
The aftermarket locker market for the JL is still kind of slim right now. I think the best options are arb and ox. To me, installing an ox locker would be AMAZING for a manual control locker. But the issue is that the install is sort of invasive. So it’s got me considering an arb setup, compressor, tank and lockers. I’m told by a shop by me that you can get stainless steel braided air lines for longevity. I also think there’s repair, or line replacement kits.
I had a case spreader for my Dana 70. Its called going from fourth to second on a full throttle downshift. The GM Performance 502 is the most effective diff spreader there is. Spread far enough to loose mesh and bust 3 teeth off the ring gear.
I have only done my toyota diffs so i never had a use for a case spreader. Thats a dana thing. I wish i could learn to do more variety of diffs out there. I cant wait to get some of these lockers on my axles
They are really nice ,but on that note really expensive... I used a aussie lunch box locker for the past 7yrs on a 77 cj7 with d44s front and rear and 38.5 swamper Tsl's.. in the rear I use a $60 spool... I dont jump dunes,, or rock race with it, I craw around for the most part,, that jeep has been all through upper tellico, and windrock.. and it has road manners aswell, def not my everyday driver, but often take it on 2hr road trips to go wheeling, also it has rcv axle shafts up front and Yukons out back,, and now that I just bragged on it,, its gonna explode next weekend when I go wheeling! 😂😂🤫
Thanks for the informative video. Planning on getting those lockers eventually for my 06 tacoma. Have the ARB bull bar bumper for the front that getting installed this week . Figure I might as well stick with the same company for the locker and apparently its the best setup .
Informative video! Always been a little skeptical of air lockers since I figured there were more places for potential issues with them, but this made me rethink that. Thanks!
You're right to be skeptical. Roughly 10% of air lockers fail on every off-road trip in my experience. I kept track for a few years on land cruiser association trail events. In the same time there were zero factory Toyota locker failures.
I was all geared up for another video, and I locked in to you! Education and Entertainment has Empowered me once again. Wi Fi-ght it. Just go to a 24 hour McDonald's! Y'all are becoming the axis of my life. How about some lockers for Jelly, for when she gets the Zoomies! LiteBriteNationSpinsMyGears!
I have a problem with ARB lockers. The twin o rings inside the air line ring (seal housing) mounted onto the axle spline gear (bearing journal) is so low quality. They begin to leak after a year and start to pump your diff oil out to the air pump and now you have an oil leak from your air pump. And when the leak increases with more wear, your lockers stop locking. You have to dismantle the whole diff to change those washers. And guess what, those also wear and here we go again. They are constantly subjected to friction when the axles are moving. This is a big big design weakness. I prefer electrically operated lockers now.
As soon as you hardwire the e-locker you remove all the nannies. And you never have to worry about your airline failing, which happens to everyone. Half the cost. No secondary system that can fail. All I need is a switch, relay, fuse and 12v.
Yep, installation error is the main reason for failure. I had an ARB front air locker installed in my LX470 in 2003 by an ARB dealer. I reported oil weeping out the air line three times when I had it back for more work. "Normal", they said, even when oil was condensing an running down the inside guard. Lost all the oil on the first part of my trip around Australia. ARB Adelaide fixed for free, but outsourced it. Outsourcer honed the damaged bearing surface where the main diff bearing seal sits. OIl leaked. I had it rebuilt again by a third party one quarter of the way around Australia, with new gears as the originals were damaged. ARB paid again, reluctantly. The air locker has never leaked even the tiniest bit of oil since the second rebuild. I have an empty collection bottle to prove it If the air seals are done correctly, and not nicked, they don't leak. At all. Don't believe anything else.
Question, since the lockers "lock" the differentials does that mean they should only be engage for strait lines, I know most uphill lines are strait but will there be any issues if you have to make turns or swerves? Thnx.
These educational videos totally rock. Also for finding wifi on the daily, why not use your smartphones and turn it into a mobile hotspot and then connect to that?
I own a toyota double cab with the e-lock rear diff,,you can only use it in 4-lo , that sucks! I,m saving my penny's for a ARB locker! Thanks for the time to explain how they work!
