No, not really.
If you're going to do it right, you will need to remove the inner bearing & that involves removing the dust seal. That means you will need new dust seals. See tip # 2.
Just pack the bearings, not the hub!
If you don't have a bearing packer, put a gob of grease in the palm of your hand & push the bearings into it. Lightly coat the spindle & races.
Don't order the seals until you get the bearings out. Because you might just need new bearings. And races.
Hint: when the bearings fall out of the carrier & roll across the floor, that's a good sign that you need new ones.
