    I noticed the pinion seal on my rear axle was leaking a bit so after i got home from a drive i pulled the rear plug and and a little air hissed out. Could the vent the stuck closed? It looks like a tube with a cap on with slots around the edge is that it, or is there more to it?

    Yep, probably stuck or plugged with crap.
    When I rebuilt a '74 D30 before installing it in my '71, the drilled hole in the diff casing and vent connection were completely plugged with sand... it was like mortar... :rofl:
    Take off the diff cover, then remove the cap, clean the hole. Install a new connector and run vent lines. :)

    loosen it up with water? then vacuum it? that's what i did.

    check your flex tube, see if that's plugged. might not be at the connector.
