8 3/4 spitting gear oil out of breather vent

IMHO the only way to overfill would be if the drivers side tire was on the ground and the pass side was raised. Then oil would fill the housing tube before coming out the filler plug hole.

@metalbender58 any chance you filled it with the housing at an angle?

stranger things have happened...

i once installed a rear for a guy. he'd just dropped it off, said it was out of his other car and had lube in it, ready to go.

what he failed to mention was that he "topped it up" while it was in the back of his pickup. the outcome was about what you would expect of something with about an extra quart of lube in there.
