    Do you really need a new one?

    Like everyone else, there was fluid blowing out my axle vent. Hey, not knowing any better I crawl under there sure enough the thing has a loose cap. I’m thinking it was broken. Nope, I was just being stupid in public. That’s the way they are make them. They just crimp a cap on top of a bolt with a hole down the center. Save yourself the $16 clean the bugger with some brake clean and put it back in the hole (For what it is it's kind of a rip). Better yet go buy a new Ford Racing cover for $80 bucks and take the plug and put it in the axle hole and put this on top of the differential cover. It will never leak again.

    Axle vent

    This vent worked just as it is supposed to work. It is a perfect replacement for the stock factory vent.

    Replace them...

    if you are doing a rear end...these may get plugged in the process...replace them and you might just save $1000's that you just put into the rear end...

    Quality Looks Good

    I bought it because I assumed the leak was coming from the vent tube, but when I went to install it the leak was at my differential pinion flange. But I digress. Based on how it looks I think this would function very well, no plastic to become brittle just good old fashion metal. Very solid looking piece that looks to be of good quality.
