Important: If the final drive looses a lot of oil, this may be
caused by an air bleeding pipe forced in inadequately.
Note that air bleeding holes (E) must be at a right angle to
the crown wheel.

In order to avoid leakage on cars fitted with a limited-slip
differential, an air bleeding cap with an additional inner
cylinder can be fitted subsequently after the car has left
the factory.
