IIRC, I used a grey silicone as a sealer- works ok for me.

Well you may be over thinking it but you are at least keeping us amused =
:-)
BTW the BN1, BN2 and 100S didn't have the "O" ring seal so I think in =
their cases the gasket was the seal..
Pooffff goes that theory..

Is this the idea: when we tighten the lug nuts, we compress the gasket =
from, say .014" to .010". At .010, the axle center makes contact with =
the spacer ring and bearing, coming to a stop. There is then .010" =
between the carrier and axle flange. The gasket takes up the slack - is =
the compressed gasket strong enough to in effect be a shim between these =
two parts?
Michael - maybe when extra-tightening of the lug nuts, the axle flange =
is also bending slightly to take up this gap.
Betcha I'm over-thinking this! :-)
