Packing rear bearings

["mike" <twobeaners@earthlink.net>]

Hi Guys,
After pulling the rear axles and cleaning and inspecting bearings, I'm ready
to re-assemble. I did not remove the bearing collars or bearings because
they seemed to be in good shape. I had flushed out the old grease. Now, I've
got a needle grease injector which works great for greasing the bearings. My
question is: Do I need to grease or pack the outer seal retainer or the
interior of the bearing housing in axle?
Thanks,
