Note that the later diffs had a plug in the flange to prevent this leakage.
When I build them, I put a wipe of sealer on the splines on final assembly, to prevent the oil migration.
Oil between the pinion & rear driveshaft flange is the big clue.
Now if the pinion nut has loosened... it indicates a completely different scenario, but you would have a very noisy diff, in addition to a leaker...

: Yes it's a fairly common problem, the
: lube is working by the splines as you
: suspect. A little dab of sealer on the
: back side of the big washer & nut
: should seal it up.
: If it's a later diff with the
: collapsible spacer pinion preload
: adjustment, be sure not to tighten it
: up any more than it was or it will
: screw up the pinion preload.
: Also make sure the vent hole is clear.

: Hi All.
: It seems my GT6 differential has
: sprung a leak. After all of last summer
: with everything high and dry, right
: away this spring I have gear lube in
: puddles under the car. After pulling
: off the driveshaft and checking the
: source of leak it appears that the seal
: and seal surface on the input flange
: are fine but somehow gear lube is
: getting to the front of the dif. by
: going between the splines of the pinion
: shaft and the splines of the flange
: and under the nut and washer at the
: front of the flange and getting flung
: around everywhere. Quite a lot of lube
: came out when I separated the
: driveshaft from the dif. flange. I've
: not seen this happen before. Are you
: guys familiar with this problem?
: P.J.

: Thanks. That's what I did and it seems
: to be good so far. Wasn't sure if
: silicone would hold up for long though.
: Would you use permatex or Silicone?
: P.J.
