If there's any in-out play in the flange itself, the retaining clip may have
failed. I've learned - the hard way! - that it is not worth the cost to use
one twice. A friend's 8-v cost us several hours of search for two very
cheap parts, and about 65 miles of driving. He has about 5 retaining rings
as spares, now, brand new, for anytime one of a group of us needs to
remove/replace a flange. We were "lucky" enough to have the failure show
prior to finishing the installation, but my '87 was parked for a year+
before I bought it because of the same failure.
If the ring is good, the sad possibility is that the bearing may be
allowing the stub shaft-and-flange assembly to wobble eccentrically, opening
a gap on one side of the sealing surface. Can you move the flange up/down
or forward/backward? If you lift it, does lube ooze out at the bottom?
This would seem to be evidence... I've seen some free motion in this area
on several transaxles that didn't seem to leak, so there apparently IS some
allowance for play. HTH

Subject: [a2-16v-list] Transmission drive flange seal problems
Hey everyone,
My 89 GTI 16v with 155K was leaking at the passenger side drive flange seal.
The drive flange itself had alot of play, so I ordered a new one along with
a seal kit.
I tore it apart and reinstalled everything and the thing was leaking after a
5 mile drive! I thought I did everything right - I packed the backside of
the seal with grease to help retain the spring per the Bentley manual, and
used a pusher made from a round piece of metal, a bolt, and a nut to push
the seal in until it was seated. I also used a pusher like the VW tool to
press the flange onto the shaft.
It looks like the gear oil is leaking between the flange and the seal. My
guess is that maybe the spring popped out of the seal when the flange was
being pressed on? Or maybe the seal isn't completely seated? I did munge the
green sleeve a bit when removing the seal, but only at the outside edge, and
it doesn't look like anything is leaking there.
Any ideas what I could have done wrong?
Thanks
-Ken
