Rear End Gear Breather?


Recommended Posts

We just replaced our rear end gear in our Pro Truck. We are running a 7.5" GM 10-Bolt with a 3.73 thick gear. We were confused on how much rear end gear lube to put in. We filled it up with about 3qts. When we ran for the first time after replacing the breather tube had "blown" out gear lube. I don't know why, but the entire evening it seemed to produce a bit more.


Did we over fill it and it overflowed? Is this common. The truck ran fine and doesn't seem to have any drivetrain issues. Just want to make sure we didn't develop a problem.
