Hi:

- 1989 Ford F250
- Ford 10.25" rear axle with full floating hubs.

Is there a vent hole in the differential? I can't find anything that looks like that. There is a wire coming out of the top, but no vent tube. Am I missing something?

The reason I'm asking is because the pinion seal and one of the axle hub seals are leaking. I thought maybe the vent was blocked or something. But I can't even find a vent.

Help me out.

Thanks.

 

I think that it is the "T" looking fitting on top. It looks like it is part of the brake lines, kinda sneaky the way they do it.
