Why would anyone want to fit an ARB air locker?

Thanks MAttyboii. Well, if you see Warren from ARB Penrith, or anyone from any ARB franchise you can tell them that at least one person will get a diff locker from somewhere, other than ARB, me. Cheers

I just ordered my front ARB locker from Matt at ARB Coopers Plains. I have talked to the Terry the workshop manager and they have good results with work I have had done before. The rear locker has worked great and it is the new design.

I have had a rear arb air locker installed nilly 6 months ago now and could not rate it high enough, as for customer support and sales, gotta do a massive thanks to Danny from the moorebank branch who went above and beyond . Very very satisfied customer here

Well where do i start?
I guess firstly this is to all those sheep out there who have been brainwashed by the advertising of ARB promoting how good their air lockers are supposed to be.
I do not deny the fact that initially the air lockers do work as intended but sadly only for a short period of time.
After working in the mechanics industry for over 10 years and have seen what happens to the lockers and the damage that they cause the vehicle.
I personally would never purchase an ARB air locker.
I know there are a lot of you out there who are saying well why not and if not then what else can i run?
Firstly there are various lockers out there that are designed for different applications and all have their pro's and cons to a degree.
To understand completely you must look at how they work and what they do to make them work. look for design faults that could cause other problems.
If you are one of these brand driven people then by all means pay for the brand name and get a locker.
If you don't know what sort of locker to get and are driven by flash advertising by big brand advertising then please take the time to read on about the things ARB do NOT tell you about their products.

Firstly inside sources tell me that ARB has closed their aussie based manufacturing plant down for the cheaper production of their Air lockers in CHINA.
This is proven by the availability to buy ARB branded air lockers on ebay and alike from china - packaged in ARB boxes with ARB etched air locker switches and all for a fraction of the price of what you can buy them for from an ARB franchisee.
A friend of mine has already purchased 2x air lockers & compressors for his hilux and the total came to a little over AU$1000 for the lot!

The main reason i personally do not like the Air locker is simply because of the design limitations.
I mean seriously - who would put 100+ psi of compressed air into their diff housing?
You'd have to be nuts!
The ARB air locker relies on 2x O-ring like seals to provide air pressure to the internal locking piston. unfortunately there must be air pressure present at all times the locker is to be engaged and these 2x thin little o-rings wear regardless you have the locker engaged or not!
The O-rings do the same number of km's as your hub seal would. Now ask your self how many times have you had to replace a leaking, dry or cracked hub seal? Further more, would you trust a hub seal to withstand 100+ psi of compressed air that has done a few km? That is what you would be asking your ARB air locker seals to do when its done a few Km's.
The diff housing does have a diff breather tube that is capable of venting slight pressure changes due to expansion and contraction from heat but unfortunately are not designed to cope with 100+psi of air being passed through them.
Further more, what happens if your breather gets blocked with mud or dirt? The air pressure has to go somewhere and unfortunately tends to pick the next easiest point of escape - an axle seal, diff pinion seal or hub seal. I have seen several seals 'pushed' out of their housing as a result of a blocked breather and a failed ARB air locker seal.
So after running your diff dry all the way back to civilisation where you can organise for your vehicle to be towed back to the closest available mechanic to get your seal popped back in and then a further more expensive job later on when you get back home to repair the leaking air locker seal. You ask your self why did i go down this path and choose this air locker?
One would think that a flimsy O-ring like seal wouldn't cost to much to replace and even a pair of them sitting in a housing couldn't be all that bad right? WRONG!
As a mechanic doing the repair work for a poor customer who had just this problem found out first hand why not to buy an ARB air locker.
The Diff center containing the locker was removed and the seal housing containing the 2x O-rings was disassembled to expose the failed seals. ARB Penrith (Our most local franchisee) was called to chase up the replacement seals.
After three whole days of being given the "oh i haven't had a chance to look the part up for you yet - give me a call back in a couple of hours" and after calling back as requested was also given the "do you have the model number for that particular model air locker" since there is nothing at all inscribed on the locker itself there is no way of knowing even what model the locker is other than just going off measurements and dimensions and isolating it down to a little over a dozen with all the same dimensions.
On Day four was told by ARB Penrith's Manager to come down and to bring a sample of the seal housing and the seals as to match the replacements up.
I drove half an hour out there from the workshop to arrive at the Penrith branch where i met the bloke who i had been on the phone with for the last 4 days. Warren. He took the seals and housing and walked out the back and was told to wait around while he matched up the replacement parts. 3/4 of an hour went past and i could see through to the workshop area where the seal housing and seals where still sitting on the bench and a group of staff where standing around enjoying a non work related conversation. I called out and asked what was going on as have been here for quite a while and was anxious to get the customer's work vehicle reassembled.
To my shock i was asked "how does it feel? how does it feel to have your time wasted by someone wanting a 50c part. I made you drive all the way down here and sit around for what 3/4 of an hour now? how does it feel to have your time wasted?"
I was shocked. I stated i only want the seals - a couple of 45mm O-rings to repair one of your company's air lockers. Can you help me or not?
Warren replied with i can sell you a complete seal housing assembly to replace your current carrier but it will be almost a thousand bux and you will have to upgrade to a single 50mm carrier bearing on one side only. either that or i will sell you a brand new air locker at full retail and tell you its a special price cos you work in the industry as he chuckled at what he had just done.
Warren at ARB Penrith refused to sell me the 2x little O-rings and said there is much more money in selling a new unit than there is in repairing them so thats why he refuses to and on that occasion literally threw the seal housing to me and told me to either buy a new air locker or piss off.
I called my boss immediately and relayed word for word what had been said and done and then further contacted the Moorebank branch where i was put in touch with the storeman since there is no such thing as a complaints department being a franchise.
The Moorebank store foreman (also named Warren) sympathised with me and said that it wasn't the first complaint nor will it ever be the last and he said that there is only 2 different sized seals for the Toyota range - being a 45mm or 50mm seal and sent me out the 45mm seals i required via post for free! to make up for the headaches and hassles.
That afternoon after receiving the seals the customer was able to get on his way and back to work after nearly a week being out of business due to his vehicle being off the road.
I have been informed by an ex ARB employee that the kind hearted Warren from the Moorebank head office no longer works for ARB and it is against ARB's hard sell policy to offer any form of support for their products not covered under warranty.

So you've decided not to go down the same path but ask what else is there?
personally i like the Torsen Gleason diff aka Detroit Truetrac.
It doesn't require compressed air into the housing
It doesn't require an air compressor to be fitted and running
it has no messy air lines nor require drilling of the diff housing
it is quiet and always engaged
works similar to a conventional LSD unit so there is no downgrade if your vehicle is currently equipped with an LSD.
Can be fitted in both front and rear diffs without causing loss of steering around corners or in the mud
compared to ARB's air locker kit is much cheaper to purchase and has no on going servicing requirements like replacing seals.

If you are heart set on installing a locker, why not look at electric solenoid lockers or external actuation lockers?
TJM for example do offer a locker similar to ARB's but from my experience back their product 100% and do offer ongoing replacement parts unlike ARB.

I am not payed in any way by any company to promote or demote the products described above however in answer to a question i was asked by Warren at ARB Penrith "What am i going to do about it?" (after i told him that he his business has the worst product support) Sharing what i have learnt from experience with everyone who chooses to read this post may be pretty good response to his question :)

for those interested in the Torsen Gleason diff check out this link for more info
Gleason's Impossible Differential
Good read. and yes air dose blow out diff oil if a seal buggeres up and a breather is blocked. Its manditory in my opinion to run all breathers into the clean side of the air cleaner intake of the engine. breather filters do not let condesation out from the air compressors as it condenses at the filter and runs back down the line when the vehicle cools down. If its conected to the air cleaner with no restriction the mosture/ air is simple consumed by the engine like any other humid air.

top read on the gleasons impossible differential link:)
I have install a true trac in the rear diff and am very happy with it, it has totally trasformed the car, am now trying to save the coin to do the front as well:D

can't recommend them enough, IMO heaps better than any other option for what i do

you did it the wrong way around . you should have done the front first lol.
This corrects the castor error in a way no other diff can . when you raise a disco the castor turns to poo . just by having a gleason in the front it tracks straight like its never been raised. no steering twitch. How much did they sting you for a gleeson here . did you know you can post them in and anything under 1000 bucks is duty free anything over 1000 bucks is 10% gst plus 5% because its a 4x4 part if you tell them that it is.

Pulled my front locker out this weekend as i haven't had it out in 10 years since the air locker install just to inspect it, and was very impressed with the condition of the the locker and diff gears. Replaced the O rings as a precaution. I should service the diffs more often as the seem to get overlooked untill a problem occurs. I have always used a high grade gear oil in the diffs and i think that this helps a lot

Hi, I put my hilux in to ARB Townsville last week (29/01/13) to get Air Lockers installed front & rear and a Longranger tank, all I can say is the service I received was fantastic. I will gladly spend more money there

Cheers, Ben

Hi Ben my son had his 2012 hilux fitted with a rear locker at ARB Townsville more than happy with the service as well . Mine was fitted in Caboulture and they bent over backwards to help me , very nice people .

where do you get Gleeson's and do they make them for Nissan patrols and about how much would it cost for both front and rear
cheers

Have you read up on gleeson differentials for 4wd ?
From what I have read if one wheel is off the ground & spinning the brake has to be applied to apply torque to the opposite wheel .
They use friction on the housing to apply torque so extreme wheel spin would wear them very quickly .
They cost the same as a locker + fitting , diff specialists supply locking differentials .
$2000.00 would be a fair estimate I expect .

Why not get the E-locker by Harrops then,Have very good reports on this site,dont need air that can leak..

Hi, This is my first post so please be gentle, I have an 80 Series 1HZ Turbo Diesel(after market) with ARB Airlockers so the Burleigh Heads store have told me by the blue airline. My air lockers loose oil through the blue airline as well and a 500km trip will have about 500mls in the bottle I have put in the place where the compressor goes. This seams excessive since the compressor has been removed and the breather line is clear...Does anyone know why this would be happening? I have so far been told its the air seals and I would need a new unit as they dont sell the air seals...Is this correct ARB? (since you are viewing this post) And if it is stuffed does anyone have a recommendation for a replacement unit. It my inlaws car and they bought it with them fitted but will never need to use them as they are only going to be driving around with a caravan for the next 5 years....I just get to make sure its all up to the task...


While we're at it can anyone recommend, (by personal experience) someone who can point me in the right direction for someone who knows about turbos up here on the Gold Coast. Works amazingly till 3000 revs then seams to stop accelerating and puff smoke out the exhaust...hasn't used any oil in 8000kn's so far...Car has only 175,000 original km's. Cheers

I doubt you can't get your locker repaired at ARB .

I believe if you don't use the gear oil recommended by your manufacturer you will have issues cause of the higher heat in your diff using the oil the installers use .

Your turbo most likely need to be de-sooted from all the articles i've read & speaking to Garrett in Brisbane .
