Thread: ARB Air Locker Installation

Ha mate I have personally fitted 3 units and never had a problem. I think most of the O ring drama was from the earlier design, they have had a new design for there O rings for a while now and like I said I haven't had any problems.

I heard TJM Pro Lockers have a different design and are more durable, but of course are less friendly to the wallet. I think they are around 200 bucks dearer or something like that. Anyway the ARB's have a good warranty so if something does happen they will probably just replace it.

Thanks for those comments.

Well the new locker is about 3 years old and still in the box so is likely to have the older style O ring and will no longer be under warranty - also as it is going into my 101, the ARB side gears will be replaced with ones I have.

So is there any point is changing the supplied O ring with one of a better quality.

Cheers

Garry

As far as I know.... old type of O ring is round. Newer type is square section. Apply vasoline when assembling and you should be fine.

My lockers have the square section seals.....square has more surface area to seal with but I don't know if thats a good or bad thing!

i had my locker installed buy a diff shop, it can be very odd at times like it will be fine and the conmressor will never run on, but other times i can be half way up the hill and its been running the hole time, but im not worryed about that,

im worryed about the fact the diff went in silent and come out sounding like there was no oil in it

Should be a red/orange small thin Viton quad ring.
Clean diff oil and housing needed so there is no rubbish in the oil.
The preload should be perfect on the carrier bearings for the diff centre or slightly on the tight side so there is no play when hot and under load.
You want to be careful doing this Garry and its alot of work compared to the locker in the rear.
I would be getting friendly with the local diff /gearbox specialist if there is one in the ACT
Wrong preload, dirt in oil/dirty air supply/ wrong pressure air supply and poor set up of the locker parts will cause the O rings to leak.
If they leak it is a strip the whole front end down again to fix.
So far my ARB has not missed a beat.
I love the detroit in the rear, TJM would be better in the front, but we have no choices do we ?

The probems are grossly overstated. They are only a small fraction of the number sold and installed.

I have the old-type F+R in my 110 and no problems.

I thought yours was pressurising the front diff and causing some diff oil out the breather.
