  • Axle vent hose

    I need a little help with a vent line problem. I have an '80 CJ7 with the Dana 20 rear end and Moser one piece axles. Whenever I drive her on the freeway, the axle vent spews SAE 90 all in my fenderwell (this is where I ran the vent line). Anybody had a similar problem? Also, I checked the oil level in the diff. and it is just below fill-hole. Help.

    Do you have your axle turned up quite a bit? If so you are over filiing it and that is coming out from pressure under use. Or it could be that for some reason your install of the one piece axle was wrong and you are overheating the oil and boiling it out.
    I would bet the first one.

      That is a possibilty that I will check on. Thanks-a-million.
