Leaking gear oil.
 

Hello to all. I've posted regarding this before and really did not get
any clear answers. Alot of useful info but no real explaination. Any,
I have a 95 YJ 4.0, manual, dana 35 rear. It is spitting alot of gear
oil out of the vent tube, down the side of the gas tank and on to my
garage floor. Thank goodness for oil dry, it works wonders!! Any way I
am confussed as to why its happening. I just serviced it myself 4 wks
ago. Pulled the cover cleaned it out. New oil. I drive 40 miles to
work, one way, mostly at highway speed. Some days I come home and none
on the garage floor, some days, a drop or two, some days like
yesterday, I come home and 10 hrs later a puddle 7" in dia. I don't
get it!! What would be causing the pressure to force it out. HELP!!

Thanks,

Greg

How can you overfill it when the fill hole is on the side, vertical? I
used 80w90 oil.

Re: Leaking gear oil.
 

Does your vent tubes extend up beyond the 'air intake line?' On mine,
differential vent tubes use rubber tubing that attach at the
differential, and run up high; the front diff. terminates next to the
top of the radiator, and I'm not sure where the rear terminates; this
keeps water out during river crossings and lets the internal pressures
equalize when the cold water hits the warm metal casing, preventing
fluid from escaping or entering through the vent tube itself or through
the axle seals.

I'm just wondering if tubing that hooked into that fixed 'vent tube'
fitting is missing? If so, that might account for the spillage.
Overfilling and wrong fluid type can also contribute.
