There should be a grease fitting behind the backing plate. Mine don't have
zerk fittings, they're threaded plugs, if so you need to put in zerk
fittings and probably take them out after greasing.
Don't see any reason to replace the bearings unless they're bad. Noise
would be a sign of a problem. They could last forever. I suppose sitting
for a long time could cause premature failure, but if it ain't broke don't
fix it.
The inner seal keeps the 90 weight from entering the bearing area, if it
leaks a little it's not a big deal.
The outer seal usually has a small spring around it, that, if it stretches,
will keep the seal from sealing.
All-in-all I wouldn't worry too much about it, but that's just me. It
wouldn't hurt to replace all the seals and bearings, but it's a lot of work
that may be largely unnecessary.

Subject: [FWDLK] Rear axle seal
On a recent driving tour of Canada I had the right rear outer seal on my
'59 Belvedere leak and contaminate my brake to the extent that I had to have
a new seal installed on the road. When I arrived home I checked out my parts
book and see that there is an inner seal and an outer seal with a bearing in
between.
My questions are 1) is that bearing a sealed bearing, or is it a grease
packed bearing?
2) What would you guys recommend I do?? Change
them all out as there is 72,000 miles on
the car.
3)Would the inner seal be leaking as well as the
outer seal??
Thanks in advance Don from Canada
