How full are you filling it? You're not filling it through the breather hole are you? If you fill it clear to the breather hole that is WAY over full... And will spit alot of oil out as it heats up.
5K trucker, Dave_in_AZ, BoxCarKidd and 2 others Thank this. -
My buddy bought some Schaefer’s that had “tack” additive in it. It started foaming out the breather hole. His mechanic told him to drain it and refill with “no tack” oil and it fixed the problem.

Hard to tell from picture, but breather should be on back side of axle. Road ram air will pressurize the housing. I sometimes run daycare at the shop!
