Here's how to grease everything upon initial installation.

First, grease your bearings and spindle by hand or with a bearing packer like part # L70025. If you are going to do it by hand, start with a gob of grease in your palm and then press the bearing into the grease with some force.

Next, insert your bearings and grease seal in the hub and mount your hub on your spindle. You should slowly pump grease into the spindle. As you are pumping the grease into the spindle, occasionally rotate the hub. This will prevent the grease from building up in one spot.

Continue to pump grease until you begin to see the outer bearing move or you see grease seeping through the outer bearing. If you pump the grease slowly and rotate the hub, you should not blow the grease seal. Once you see the grease seeping through, you can install the washer, spindle nut and nut retainer. Keep in mind, when threading on the castle nut, you will want to tighten the nut until it is hand tight and then slightly back it off.

Typically a grease seal can't be removed without destroying it.
