Maybe an overfilled differential or inter-mixed gear lubes. Quote "Mebbe I'm too ugly and stupid to give up!"

Your right rhasler, I should have been a Gynecologist instead of a shade tree mechanic. I actually have more experience and time with the first field of business. mike Quote Link to comment https://www.bigmacktrucks.com/topic/18316-rear-axle-leak/#findComment-74381 Share on other sites More sharing options...

It is a fact of life that they will clog under normal to dusty conditions. most vents have a cap which is loose on the stem. Pick up on the cap with your fingers and spin it, that is all it takes. A pressurized housing could lead to a failed seal. Time. temp, and mechanical also can contribute, although a wheel seal can fail for no apparent reason at all. Understanding how and why components function, along with good pm help, but sometimes just to get your attention a truck will reach out and bite you on the ass anyway.
