we installed a D44 with 4.56 gears and an ARB airlocker in my 4" lifted '00 TJ. I got a Rockcrusher diff cover to raise the fill plug to add extra fluid because of the increased pinion angle. Problem is that the fluid is coming out the vent tube. I expected some but it has dropped the level down to where you can't touch it with your finger through the fill plug hole. It took a little less than a quart to fill it back up. Has anybody seen this before? Do you think there could be something wrong with the locker? We checked for air leaks at installation, could it leak when it gets warm/hot?
