Axle Vent
An automotive axle vent breather is a small, often overlooked component of a vehicle's drivetrain system that plays an important role in preventing damage to the axle housing assembly. The vent is typically a small metal fitting that is located on the top of the housing, near the differential. Its primary function is to equalize air pressure inside the axle housing, preventing the buildup of pressure that could cause seals to fail or oil to leak out of the axle. The axle vent works by allowing air to flow into and out of the axle housing as the temperature changes, ensuring that the pressure remains constant. This helps to prevent damage to the axle and other components of the drivetrain system. If the vent becomes clogged or blocked, pressure can build up inside the axle, leading to leaks or damage to the seals.
