ARB puking gear oil

Curious if anyone has had this issue. I have a PR44 with arb. About a month ago I had a ton of gear oil puking out of the solenoid on the arb compressor. Off Road evo replaced the seals on the arb and the solenoid compliments of dynatrac s warranty. Today I noticed some gear oil coming from the solenoid again. Ugh. I haven't used the front locker since the rebuild because I have a new suspension going on and the coilovers I have are already sold. Didn't wanna damage anything that is sold. Of course I did ensure it was engaging/disengaging properly after the rebuild but I haven't wheeled it anywhere that required the front locker. My vent tube is completely clear as well. Any ideas why it would go out again so soon? Thanks for the help.

Either residual oil in the air line/ solenoid or new seals are torn too. As for why the new seal could be bad... Could be install error, burr tore it, or loose preload in the bearings allowing the locker to shift side to side wearing on the seal.

That's assuming you checked common stuff such as the vent not blocked and allowing diff to pressurize. Eta, didn't see that you already checked it

Thanks bthomas. The axle was custom built by DYNATRAC. They installed the gears , locker, shafts, etc. the rebuild was done by the boys at Off Road Evo. I did check the vent tube and its good. I should add the solenoid was not salvageable and was replaced with the rebuild. It was full of oil. They said they blew out the airlines as well to clear any oil.

What is the oil level? Overfilled should puke out the vent first, but checking won't hurt.

I have this same problem with my rear arb but my solenoid is still working just fine so Im leaving it for now. Arb sells a purge valve that will purge the oil/moisture out of the line

Seems like a common problem that can happen even if the seals are good.

Those would be nice, but at that price, I'll just disconnect at the axle and flip my switch to blow the line out.
