As your vehicle’s differential works, the gears spinning in the oil bath create friction and heat This is the reason why the oil breather tube is made and designed to be in a vehicle This heat causes the air.

Failure of the differential breather leads to two distinct and damaging outcomes
If the breather becomes clogged with dirt, mud, or rust, it.
To accommodate the increase in air pressure resulting from this heat, manufacturers add a vent tube to the top of the axle as means of releasing this pressurized air to the atmosphere. Turns out the way the breather tube was positioned in the axle housing the gears were throwing oil into the tube at such velocity that it was causing it to spew out the breather. For decades, the prevailing powertrain venting method has been threading a rubber or plastic vent breather tube from the component to a level above the water fording line, and ending the. If the vent stops venting it not functioning will cause axle seals, pinion seals to blow out
Also the collection of debris on the axle lubricant residue that builds up ( what you've got) will gum up. Discover the 7 most common differential breather installation mistakes causing diff breather failures—and how to fix or prevent them correctly. Can anyone tell me why If your drivetrain springs a leak, it could be that the breather/s are blocked
After plugging the leak, it’s important to clear the breather
All drivetrain components (front and rear axles, gearbox. I even replaced the tube and breather from a dry truck and oil still is coming out The axle has a replacement used differential from a different truck that i dropped in Gates consider what would happen if the pressure generated in the engine was not evacuated
Without a breather, or if your breather is clogged, the pressure that builds up inside the axle housing will most likely push gear oil past your pinion or axle seals. I turned the breather 180 degrees so the breather tube was now facing the axle housing, cleaned all the oil off with some brake cleaner and continued the test drive The second half of the test. You may need to fix the breather by replacing it or extending it with a hose to a higher location
I have extensions on both axles that run to an off road filter on the upper part of the firewall.
So, i got the breather tube off and the cad Tube was clear, the outer passenger side axle shaft was indeed disconnected, and the fluid still had quite a bit of clearness to it I have no idea why. To balance air pressure on the transmission, these breathers are mounted
The inside air expands during car. This is why we have the oil breather tube
