Why does the front differential blow oil out?

The front differential can blow oil out due to several reasons, including overfilling, a worn or damaged seal, or excessive pressure buildup from overheating. When the differential is overfilled, the excess oil can be forced out through the vent or seals. Additionally, if the seals are compromised, they may fail to contain the oil, leading to leaks. Regular maintenance and monitoring of fluid levels can help prevent these issues.
