Arb air leak???

[JohnnyX]

So when I engage my rear locker compressor stays on n I can hear air dumpin outta my diff vent hose. Has anybody had this issue n what was it? Lockers n gears have only 1364 miles on em.

It could be the fitting at the top of the diff housing is sealed properly

I checked it but it's definitely internal not the fittin on top I'll have open it up I'm jus wondering if I'll have to pull the whole carrier

With the compressor on take a spray bottle with a soapy water solution, I used dish soap. Spray an aid fitting union. The one leaking will have the bubbles. Tighten down until the bubbles are gone. I use this trick to find pin holes in air lines especially ones you cannot hear.

There is an internal O ring.....guy's I've known with ARB leaks that blow air out of the axle vent have had trouble with this O ring.

So if that's the issue the whole carrier will have to be pulled?

Mine did that, and yea, you've gotta pull the carrier and replace the seal housing o-ring. Another sign of that is gear oil in your ARB air line.

Yep, EZ-E is right......has to be stripped down. I've also heard the "oil in the line" comment, too. Apparently, the older ARB lockers were a bit more prone to this....there was a design change some time ago, from what I understand.
