Air lockers... O-rings gone?

[V8 Middy]

I went to engage my rear locker the other day and I just heard a continuous hissing of air. Tracked it down to be coming from the rear diff breather. Does this mean I have the dreaded blown O-ring seal?

How much does it cost to fix?

Thanks

sounds like it, couple of dollars fror the o ring and bout $300 in labour, do it yourself if you can

I'm guessing that despite the fact that its a well known problem, there's no warrantee?

only if from install, wearing part, even if you cant do it yourself, cheaper to pull the centre out and take it to the local diff bloke
