[Healeys] BN2 back axle

[Michael Oritt]

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.
