How To Overhaul Your Wheel Bearings

Yet another excellent webvid tutorial from Alex at http://bicycletutor.com/. If you've never repacked bearings you need to watch this. Alex makes it look quite easy, and in my experience it isn't that bad, as long as you are doing it over a clean work surface. ie. I've dropped ball bearings in dirt and then had to clean them off thoroughly before putting them in (very time consuming, and embarrassing if done in front of others).
This is great knowledge to have, because you can rebuild good hubs and save yourself a lot of cash, remember bike coops and groups frequently have old but excellent quality hubs sitting around that you can either get free or really cheap and rebuild. An hour of work and $3 in grease and ball bearings and you've got a great hub.
If you don't know how to tell if your bearings are worn out, Alex has another great webvid that shows you http://bicycletutor.com/check-bearing-wear/
