Default "Overfilled" Diffs

I got (OK, won at Pig Gig ) a Solid diff cover for my yet-to-be-installed D44.

I see this (and other) aftermarket covers raise the fill plug to allow additional diff lube capacity.

The way I see it, a higher level of diff lube is going to run into the axle tubes down to the seals.

Is this a:

1) Good thing? (more lube = more lubrication/cooling and a given amount of impurities distributed across a larger volume of lube (...dilution is the solution to pollution...)

2) Bad thing? (lube sloshing around seals designed for a lower level of lube, aeration/foaming of lube as it sloshes about)

3) Neither good nor bad?

Theoretically it sounds good, but theoretically a bumblebee can't fly.

This is the Pub. Leave common sense at the door.

well from what i have put togheter , raised fill plugs do add more fluid to compensate for higher pinion angles. when you lift a vehicle the pinion changes, so the diff fluid levels shrink because of the angle. so all in all its just compensation.

hope i made sense and helped

Never had a problem with a higher dif level. Did it for the same reason, trying to lube the pinion bearings when tipped up.
