I'm curious about your locker setup. Do you have a rubicon locker pump for the front and the ARB pump plumbed to the rear? So you have to turn on your ARB compressor via a switch and then the rear locker via another switch?
I ask because folks have mentioned that the ARB locker requires a much higher pressure to engage than the 5 psi rubilocker pump.
I had originally thought it was stock Rubicon Lockers and 4.10 gears.
At a glance from both differentials they’re ran to the stock locker pumps. There aren’t any other switches from what I saw in the dash, so I assumed it’s ran as if I had both OE lockers.
I’m going to have to dig into it once I wire the air compressor and find out exactly how the rear locker is connected/ran.
