ARB Carrier leaking air internally 8" front diff

so my front locker when i would engage it, would be kicking on the compressor every few seconds and eventually blow gear oil out the vent tube. thought it was the orings in the seal housing but they look perfect and when i pressurize the carrier itself (past the seal housing) it still leaks air inside. i think its the bonded seal inside the carrier, does that sound about right? and is it pretty simple to change? ive never torn apart a locking carrier. any input is appreciated

 

im thinking its number one (bonded seal) on the schematic.
