Sounds funny, and no, my rear is fine, it is my cars rear-end. Need help figuring this out. I have a Ford 9" and it is vented with one those copper plugs from Jegs on the top side of the housing, anyways, with any extended driving I have gear oil coming out of this vent, like there is un-due pressure in there? Not sure what the problem is, and the gear fluid is filled correctly with it at the bottom of the plug hole or just enough to have it flow out. Anyone else have this problem? The lash is should be good, have not re-checked but there is also a Tru-Trac in there? Standard gear oil is used, should there be an additive? Not sure what's up? Thanks.
Blame it on the dog and let loose. No need to be uncomfortable. :laugh: Sorry I have no rear-end knowledge. (read that anyway you want to.):TU:
That is what I was thinking. I have new tubes so no vent. Ended up putting the vent on top, bad move on my part. You think I even need the vent or maybe at least run a line to give the fluid some room to float? Any ideas is good. Thanks.
Yep, I think you need a vent. If you can run the hose higher than the fitting on the rear end, it ought to work. The lube should run back down the tube into the rear end.
Something else that will work is to make a breather in the driver axle tube and the other passenger axle tube connect them and use a 'T' fitting at the top with shorter rubber hose and vent tube over the center section top. This will equal the pressure from side to side of the housing and also release the pressure with LESS force. Hope this helps. Jim Good Luck.
I am thinking of doing this but gonna give one more shot before I take the rear apart. Unless there is an ancient chinease secret of doing this on the car? Anyway, tried the hose thing with a 90 eldbow at the houseing to stop the direct throw to no avail. Any last simple ideas, it was working until I gave the car on a hour drive in 80 degree weather. Seeped right through that copper vent that was mounted to hose ran through my bulk head. Anyone have luck with one of those Currie Cap style breathers. I thing there is like a pressure valve on the inside. OR would the trutrac need an additive to either thicken up or dillute the 80/90 in there. All ideas open, this leak is irritating me. At least its not a seal, and all in the breather, but what gives I have hopes of getting back on the dyno for one last tune and off to the track, but that won't happen till the leak is gone. It is not a ton, but enough to be noticed.
