CherokeeGuy1998 Sorry it's taken me so long to get back. Thanks for all of the suggestions.

It was one of the solenoids. I left the engine off, ran the compressor, and I could hear air escaping. I felt around the solenoids and found a strong blast of air coming out the top of one of the solenoids. The black plastic bodies of these solenoids have a hole machined into the top of them to release the air when the locker is disengaged and this is where the air is escaping. I probably have a bad O-ring that needs replacing.

Thanks again for everyone's input.

Indy 2 solenoids? My GUESS would be the solenoids themselves are leaking either internally or at the lines from the solenoids to the lockers. If they're not sealing correctly you're probably getting a little air nonstop to the lockers but not enough to engage them. With the lockers engaged you have full pressure to both lines and nowhere for the air to go until you turn them off. I'd start by checking for a good seal on both sides of the output air lines.

Leaking when on could be anything starting at the tube connection to the solenoid on to the axle internals. Eliminate the external possibilities first. My front axle ARB was bought new in a buddies Jeep in 1997, then used to me and in my Jeep since 1999, and still has the original o-rings with no leaks. They are not necessarily prone to failure.

JeeperDon I just use windex. It's incredibly handy and bubbles enough to figure things out.

zillla If the lockers are not engaged it must be leaking through the solenoid threads or just leaking by. Get a bottle of Snoop and have a look.

Weird ARB Air Locker Leak

I have a very strange leak that I can't lock down. My compressor will cycle every 10-15 seconds if:
a) no lockers are engaged or
b) the rear lock is engage or
c) the front locker is engaged.

But if both lockers are engaged, absolutely no leaking at all!

I recently replaced my broken Viair gauge and thought that had been the problem all along as I could easily hear air escaping out the body. With the new one installed, no air can be heard, but the problem is just as bad as before.

I'm guessing the problem is likely in the solenoids, but I can't explain how having both engaged "fixes" the leak.
