on the actual front diffr, pinion or the front transfer case seal
the front seal is like the rear.
its a crush cage.
that means when you remove the pinion yoke/flange big bolt
the crash cage is destroyed. also wrecking pinion gear to ring gear back lash..oops.. big big mess-up there...$$$$$$
and such cage must be replaced.
how can you be sure its leaking, when the engine this old loves leak oil
i bet that oil on the ground does not small at all like the nasty stink of hypoid GL5 gear lube.
why not post how to find leaks first
and not do $1000 damage
no engine size posted G16? J20?>
The G16, ill demonstrate (coin toss)
Distributor 2 , o-rings leak like made, all do this old !!!!
same with the 60k mile service and valve cover gasket
all leak, for that reason alone, on all 1990s era
next is cam seal
pan seal (or pan is rusted thru as many see (today)
oil pump seal
and gawd forbid the rear main seal , engine.
easy peasy japanezzy
why not ask your mechanic to sniff that oil first and save a fortune
see man pulling axle to remove pan
wana do that?
to replace this seal, remove the carrier first
then take it to a shop that can rework the carrier
the correct way.
