The link is good. I would suggest a couple ideas for consideration. You can get inside seals with two springs. They are called double seals or double spring seals. The single ones always blow out with BBs. Second, you can buy Corrosion Block grease in a tube. If you don't know about Corrosion Block, find out. I came out of the Baja one time with nothing in my wheel but salt water and a little Corrosion Block grease still in there for lubrication. It was running fairly cool. Last, if you put together a road kit of extra bearings and stuff to rebuild on the road, don't forget an extra nut and cotter key. Ask me how I know. Try finding one in Esenada frigging Mexico. The only other place i had a wheel bearing disaster (on my truck this time) was in the Yukon. Those are the only places where bearings fail. They sit there and wait until they can really skrew you.
