Dana 44 ARB problem

I installed my ARBs. When I tested them, the D44 in the rear worked fine for about 5~10 minutes; then, the compressor came on and I heard an air leak. Upon closer inspection, I realized this air leak was coming from the rear axle tubes with the smell of differential fluid.

I checked the bulkhead connector, hoping that was the problem...ordered a new one for Rusty's. The next day, I had the bulkhead connector buttoned back you, but still had the problem. I ordered a new seal housing. I haven't had time to tear into it yet (wanted to have ALL the parts I might need in hand before I start this).

Problem 1: I receive a bulkhead connector PN 170102, which is double compression type for a 5mm plastic tube to 3/16" copper tube. The ARB came with (and parts list specifies) PN 170111, which is an O-ring type for a 5mm plastic tube to 3.5mm copper tube. The salesman at Rusty's swears it will work. Does this sound logical?

Thanks for the help.

Are you sure its leaking at the bulk head fitting, because it could be leaking at the o rings inside collar

x2 - When I installed my ARB I picked up an extra set of O-rings just in case they leaked.

I haven't had time to open up the differential. I was hoping someone had seen something like this before and had some insight. Thanks for the help...I'll check the O-rings in the collar this weekend

Unfortunately, sometimes the copper tube will crack at the actuator. The only way to know is to disassemble.
