MGB Workshop Manual says "Fill each bearing with grease ensuring a small
protrusion either side of the bearing. Fill the cavity between the bearing
and the oil seal and lightly smear the spacer with grease. Do not fill the
cavity between the bearings or the grease-retaining cap with grease". To
that I would add only pack the bearings from one side and keep going till it
comes out the other. Don't be tempted to pack from both sides to save
time - it just traps air inside the bearing and there will be insufficient
grease.
