Well, finished hooking up the compressor and ARB air lockers. Tested the front locker, works just fine. Tried testing the rear locker but it won't engage at all. It's not the solenoid or the air line. Hooked my shop compressor up directly to the rear locker and set it to 150psi, still no luck. It's been a year and a half since it was installed, but I have also driven it regularly since then.
I'm hoping to not have to crack it open if I can help it, but it is looking that way. Not sure if moisture worked its way into the locker and is frozen (it's been highs of about 20 and lows in the single digits lately) or if something else is wrong. I put a hot air gun on the pumpkin for about a half hour to try to defrost it, not sure if that was enough though. It's not leaking either as it does pressurize and I don't hear air coming out of the breather. So either the line inside the pumpkin is blocked or the piston is frozen in place due to either water, grit, or rust.
I'm going to take it out for a drive tomorrow or Saturday to see if I can heat the diff up enough to be sure it's not due to frozen water. If that doesn't work then I'm probably going to have to pull the diff apart to see what is wrong with it.
Any thoughts?
