Considering I don't intend to drop my toyhauler into the ocean at the end of 40 lb. test line, the need to keep my wheel bearings protected to that degree is probably not necessary. Seems unlikely that most car manufacturers use Almagard 3752, and I've never had a wheel bearing go bad in probably 40 years and several hundreds of thousands of miles. So maybe Almagard 3752 may not be strictly necessary for the majority of drivers who avoid driving into the ocean. :)
I imagine if I ever repack a wheel bearing again I will probably use what I used the last time: some kind of grease that came in a tube. :) Still going strong too, amazingly enough.
