RE: [alfa] remove the filler plug before the drain plug

["Colli, Anthony G" <Anthony.Colli@xxxxxxx>]

You should always remove the filler plug before removing the drain plug,
or at least crack it free first. This assures that you can get the
filler open to refill whatever it was you just drained.

Hmm - I can't figure out why that would be important.  At first I
thought "sure, you need to let air into the differential in order for
the fluid to drain quickly and completely".  But then I remembered that
the diff has a little piece of hooked tubing welded to one of the axle
tubes that admits outside air (I guess so that pressure can't build up
inside the diff, and push oil out through the seals).

So, why take out the filler plug first?  Is this like when you
disconnect a battery, you remove the ground wire first? That one I
understand.  Both differential plugs need to come out anyways when you
are changing fluid, so I guess it doesn't hurt to start with the upper
one.  But, why?

Sorry to put you on the spot Dean - Jay Mackro
