REAR DRIVE AXLE VENT - OIL LEAK....2013 GT Mustang

[Scrape]

Sometimes the venting issue causes the seals to blow from what I read. How true it is I am not sure.

It's the lack of venting that is the problem. I've been in the gear reducer business for too many years and know all too well the importance of proper venting. We use pressure relief units (similar to a BOV on a turbo or blower), and straight breather filters. The problem with the pressure relief types, if they don't open, the pressure will take the path of least resistance, more often than not that is the seal. Even if you have the overflow canister, if the valve fails to open you will still have a leak (because the system is sealed).

I've got an old school vent n hose set up we'll be trying on Stephens car. Feel pretty strong it will 100% eliminate the premature pinion / axle seal failures.
