Hey folks! the trailer wheel bearing topic came up between some friends of mine, and a friend of mine told me about Vault hub assemblies. looks neat anyhow.... apparently the people who have them are thrilled with them, although I don't presonally know anyone who has had them... still, if they offer a 10 year warranty, they might be worth a try for those of us who travel a lot. just thought I would pass this along!http://www.ufpnet.com/Portals/0/PDFs...20Brochure.pdf
