Hi, back in May this year I had a LOT of work done on my Toyota Hilux 1998 dual cab LN167 which included the fitment of a rear air-locker, at an ARB store.
.
Since the fitment of the rear locker, it sometimes does not engage, I.E when you activate the compressor and the locker, the compressed air instead of locking the rear diff it blows the compressed air out through the diff breather.
.
I've now had it back to the ARB store three times in the last three weeks. They removed the diff each time and replaced the seals in the locker.
.
When I took it back again today, I was told that sometimes the locking ring that slides over the
spider gears, does not 'line-up" and this can cause the unit not to seal completely.
.
I was told to correct this problem that I should drive a short distance forward so the locking ring can 'line-up" with the
spider gears. Once it has "lined-up" the locking ring will engage and complete the seal.
.
Has anyone else had a problem like this with their air-locker.
.
Thanks
Dave

I have an ARB locker in the rear of my Troopy. On the odd occasion when I have engaged the locker I have heard the clunk after I start to drive off which I have accepted as the gears then meshing. I have never had air escape through the dif breather.
From what I remember of the locking mechanism the air should not escape regardless of gear meshing or not. If that were the case then the locking unit would not be getting full pressure to engage. I suggest that something is not right. Have they installed the correct unit? There was a report on another
forum (LCOOL ?) about someone having a problem causing breakage and it turned out to be the wrong version that had slightly different dimensions.
Frustrating when you have paid for a supposed proven unit.
Good luck

They need to refit the seal etc inside... (if your supplier / fitter is anything like the Sunshine Coast you will probably have drama trying to get them to do anything to help you - I know I did)
Mine does the same thing as yours sometimes also but generally only needs to be switched off and then on again... usually it only happens when I don't want it to such as when the car is on a 60 degree angle going up or down a
hill and the very last thing I want to hear is the compressor running on.. grrrr
Don't get me wrong I do love having lockers with the abiltiy to switch them on and off but I have had a few issues with
mine that have taken the shine off the purchase..
