        Axle breather

        Fixed my issue with my original leaking breather. Cheap to purchase and only takes about 10 minutes to install. Highly recommend if your breather is leaking.

        Easy fix, easy install

        Easy removal, and easy install. You may not necessarily need this part. I replaced mine but I learned that it was the dealership who overfilled my rear diff

        Still leaking

        I replaced the original vent with this one, no difference at all. Still seaping the same as the original did. Don’t waste 15 bucks on this.
