You-tube to the rescue! There are more free etrailer videos at their site that are pretty interesting. Like the magnet and the brakes videos. Here's the link:

One thing about the etrailer videos that makes me wince is punching the seal in and levering it out with a screw driver. If we chew up the hub surfaces, the new seal might leak grease. Its a metal-to -metal joint after all. I usually use a claw hammer under the seal and bear against a piece of thin plywood to pull the seal. Its quick and easy with no damage (except for the old seal). I also like a rubber or plastic dead-blow hammer instead of hammering with a metal hammer. One thing I do like about the video is it reminds us not to mix greases. Wipe out all the old grease and do an extra good job if you don't know the brand and type of grease already in there.
When you get the bearings out, be sure to read the bearing numbers and seal numbers. Write them down and keep the paper in the glove compartment for future reference. If you ever have problems on the road, you will be able to buy parts without taking stuff apart first.
I usually keep a spare set of bearings all greased up and drop them in during repacking. If the old races look good (no marks, etc) this speeds up a repacking job and everything goes back together quickly. Then I can take my time cleaning, inspecting, and repacking the spare set for re-use. I just feel better when the hub and wheel are back on, you never know when rain, wind-blown dust or a chatty neighbor will interfere with the process.
