What Bob says.
The inner seal on the axle is the critical piece and if there is wear on
the sealing surface you will need to fit a Speedi-Sleeve or similar repair
piece.
BTW SKF and others make what they call semi-sealed or sealed bearings with
plastic or fibre pieces on one or both sides of the bearing but since the
sealed ones are not filled with oil I have never understood how they are
supposed to get lubrication.

Can someone explain how the hub oil seals are meant to work. They
are inbord of the hub bearings. Are the hubs meant to be packed
with grease? ( the service manual suggests they should, but the
same manual doesn't tell you to pack the hub with grease when
changing hub bearings and seals). Is the back axle oil intended to
pass across the oil seal to the hub bearing? If so, then the paper
gasket in the hub flange to half-shaft joint will need to be oil
tight.
