You don't touch the adjusting rings. They set the bearing preload and ring
gear position. The most likely cause of leaking is the flange seal and they
can be replaced. Make sure the tranny is not over filled and that the vent
is clear. A small leak is no reason for concern. All seals on rotating parts
have to leak just a bit or the seal will wear out anyway. If the leak is
from the o-ring on the outside of the bearing carrier I would just leave
unless it starts leaking enough to be a problem.

My trany is leaking some oil on the left side, on the drive flange. All the
other areas are completely dry!
Not sure if I can carefully tighten the adjusting ring,... Would appreciate
some feedback - thanks,

Martin
