Hey guys.

Basically I recently noticed an odd noise coming from the front diff when in 4wheel drive when on the acceleration side. When I'm coasting, or off the gas, I don't hear it. When I'm 2wheel drive, I hear nothing at all

A little bit of back ground. I have an ARB locker in the diff and tho I've had it in the diff for several years now, it's never been hooked up to work. The furthest I got was running the air tube from the diff and rolled up the extra slacking tubing up over the diff and zip tied it. Noticed there would be diff fluid coming out of the tube when it got hot. Is the breather clogged? Why did fluid come out of the air tube of the locker? If the air locker tube was hooked up to the actuator, would it have developed air pressure in the tube so that the fluid didnt escape into the air tube of the locker? Or is there not supposed to be any fluid in that tube at all, regardless if its hooked up to the actuator or not?
