Default Dana 44 rear

I need a little help I have a Dana 44 with a ARB locker and 4.56 gears when I run down the highway at 65 to 70 mph it spits out rear end lube through the vent tube but around town it is fine I have checked and it is not over filled and I'm using the recommended fluid. My question is this normal or what should I be looking for? Thanks

Is it an aftermarket cover with a fill plug that is higher than the stock one?

I have the same issue with my front axle, and it's because the fill level is almost as high as the breather port on the back of the axle. Try running a lower fluid level if this is the case.

Is your ARB engaged or disengaged? Does it work properly off road?

Also, has the axle housing been rotated for better pinion angle, which may have raised the fill hole location?

It's a stock cover it has only happened one other time I did just change out the vent hose to be sure it was not pinched or plugged. Thanks for your input

ARB is disengaged and I'm not sure about off road I will have to check that out soon I'm heading to DOA and it would suck if it did not work. Thanks for your input

If I remember correctly it has to do with the way the carrier bearings are on the arb and they don't allow the oil to drain back into the diff from the tubes fast enough. There is a small groove/notch in the lower part of the tube that must be enlarged to allow more flow. Been a while though so could be wrong

Thanks that is what I'm finding out when I bought the jeep the ARB was in there and when I changed the fluid I did not look plus I don't think I can see it with the carrier in. Do I need a spreader to remover the carrier or can I just pull the retainers and it will come out to inspect the drainage port? Thanks

Its probly this. Most people dont know about knotching the tube and nobody reads directions lol
ther should be about .020 press on the carrier so a spreader is helpfull but not necessary
