The outer flange seal wouldn't cause his problem.  It's the plug seal in the
center of the flange.
Remove axle, clean out the grease and oil from flange recess, brake cleaner
to remove any residual oil, wait until dry and apply silicone RTV all over
the outside of cap/flange interface.
Will never leak into the CV's again.

Yes.  There is a seal that presses into the side of the tranny and seals
against each flange.  If y look under the plug...there is a clip that holds
the flange on.  There is a strong spring under the flange.  You need to
press the flange down, remove the clip, and the flange will come out.  Then
you will see the seal.  There is of course a special tool to press the
flange down.  Y can remove the clip without the tool...but getting the clip
on for installation will be fun without the tool :)

There is an 8mm thread in the middle of the shaft in the tranny...the
special tool threads into this hole to push the flange in.  You can make a
tool to work.

Westy. When I disconnected my right inboard CV joint, gear oil poured out of
the center of the Drive Flange because the center sealing plug had fallen
out. I've got new plugs to install, but my question is this: What seals the
the Outside Diameter of the Drive Flange? Bentley 35.2 shows the Drive
Flange in detail, including the center sealing plug, but I don't see how the
gear oil is prevented from running out from around the outside of the shaft.
Looking at the evidence of my transmission leak/seep, it sure seems like
I've got some seepage there. Can the Drive Flange Outer Diameter be sealed
without removing and tearing down the transmission?
