Differential Whine & Adding Oil 120-130

'68 Amazon, ~140k miles
I believe I'm hearing a whine from the differential. I thought it might
be leaking a bit (there's a healthy coat of greasy muck on the bottom).
My Haynes manual doesn't show much detail besides rebuilding the
whole unit. I removed the bolt in the back (which is only about 1/3rd
up from the bottom), and a little oil spilled out.
Can someone tell me, is that the filler hole, or the drain?
I don't see any filler near the top.
Thanks to all for help keeping my Amazon alive!

    Patrick -
    Good call on the bearings. I haven't checked yet because
    it's been raining every day here (in Washington D.C.) and
    I don't have a garage.
    I'll check this week when it's dry.
    ah, one day I'll have my own garage...

    Thanks. -John

    I only hear the whine when it's cold.

      Drive shaft support bearing. $20.00 for a cheap one. $40.00 for a quality one. If the rubbber donut is still firm and flexible you can reuse it. R&R takes 1 hr if you know what you're doing 3 if you don't. YOu can pull the B with a block of wood and a heavy hammer although a press would be nicer. Garage should not charge more than 1 hr. These Bs whine when they're cold but fail without warning when they are hot, usually at highway speeds and it's not pleasant. Been there, patrick.
