First of all, you need to determine where it's leaking.
It's very rare for the diff to leak at the parting line of
the case. Usually, the leaks are at the axle seals, vent
which is located on the drivers side of the axle, and
sometimes the pinion seal. There are no gaskets
for this unit, it uses anaerobic sealer. If you haven't
worked on these diffs before, I would have to say that
I couldn't recommend it as an "easy DIY'er job". But
having said that, if you decide to take the plunge, I can
probably make it a fairly painless job if you need the
I've been told by more than one person, that all of the IFS axles leak
and the time and effort to repair the seals simply isn't worth it. my
seals leak on both sides.... never enough to leave a drip on the
driveway, and I just pull the fill plug come oil change time.
On the older models that's true. But there are still plenty of
people that want to have their leaks fixed. Plus, it's always
a good idea to make sure that it's not the vent on the drivers
side leaking. That leak can cost you a front diff.
Thanks for the info, Ian. I do think the leak may be where the
driveline enters the diff (is this called the pinion seal?), and the
fluid may be hitting the u-joint and flipping all over the diff. I'll
check the vent for signs of leakage as well. I don't think the axles
are leaking, because the axles themselves are dry with no signs of
leakage. Thanks again.
