Greasing new wheel bearings and hub.

It needs grease but don’t fill it up. @dadsbee has it about right, a little too much for me. I like to cover the spindle with a thin coating.

Read section 0 of your service manual, lubrication and maintenance. Lots of good info in there. It says don’t lube rear wheel bearings, but they need to be repacked periodically on 8.75 and Dans 60 cars because the ride in grease not gear oil. These rear wheel bearings a long time with repacking.
