ARB rear diff air locker

G'day,
Yeh, I've had the same thing with my front airlocker. Although in may case the oil has been seeping out of the solenoid, which lives near the brake master cylinder; the compressor is in the cargo area. I am guessing your compressor is mounted under the bonnet and that the solenoid is on the compressor?
The only thing I can think of to minimise the issue is to switch the locker on from time to time. You can do this even on the bitumen PROVIDED YOU ARE TRAVELLING IN A STRAIGHT LINE AT THE TIME. My theory for saying this is that I believe the oil is from the diff and is 'climbing' the air hose via capiliary action (but like many other times.....I could be wrong about that!!!!!! lolol)
Hope this helps a bit

I had the same problem and the cure was to use it more often. I throw it in even if I don't really need it just to give it a workout, haven't had a problem since. Dunno why, maybe a seal drying out.

Hi gra
From the info I have been given by ARB if it is just an oil film it is acceptable if there seems to be a quantity of oil coming from the solenoid a "O" needs replacing.
no one is saying what a quntity of oil is

I had this expereince with a 100 series front locker. ARB re set the unit and replaced all seals but it did not make a huge diffrerence. The only option was to fit a internal valve inside the diff housing, this sends all the oil back to the diff eliminating and leaking around the solenoid. They did say that it does require to be operated regulary to help reduce this.

thanks all for the replies, will try the turning on more often to see if that helps, cant believe its the 'o's already,

cheers

Gday
Mine too
common problem if you can see it as a problem....if you want to, ring ARB and ask them politely for a drain pipe to fit to the solenoid......then the oil can be directed to a place that needs oiling :-)
Another thing you can do is remove the cap that the breather hose has on it and install a old ryco fuel filter instead to keep the dirt out....this will stop water getting through the seals aswell when you go swimming...
