rear axle vent

My rear pinion seal started leaking and after searching the archives learned that a blocked vent may cause it. I looked for the vent but don't see it. (1995 f150 4x4 5speed I6) Anybody know exactly where it is? Thanks!

On most vehicles the vent is actually a rubber tube or metal 'tit' on the top of the differential housing or axle tube.

If you know what rear-end you have then somebody can probably answer with great specificity.

The tag on the axle reads 5830J
3 55 88 5E25. It has the electronic speedo connector on the top front of the diff housing. Any help??? Thanks again.

I have a book for the 99, 8.8 inch rear axle. It looks to me that the vent for that one is on the drivers side axle tube just imboard of the shock attachment.

The vent likely has a hose on it. The hose should disappear up into the frame of the truck.

Found it! There is a fitting with two brake lines and the vent tube coming up to the frame. On the end there is a barbed plastic fitting that was packed full of red Oklahoma clay. I cleaned it out and topped off the differential. I'll let ya'll know if that fixes it. Thanks once again!
