    Good question, though. Modern cars--well, 'modern' since about
    1980--can supposedly go indefinitely without a diff fluid change
    (most have no drain so it's somewhat inconvenient to do so anyway).
    I think, with full-syn oil you could go 100K miles or more, even in
    a Healey. But, the rear axle housing has a vent and, theoretically,
    water could get in and if you try to ford the Mississippi you might
    want to check for 'milkshake' (really, I just wanted to see if I
