The bearing is actually 100% sealed from all road elements, and teflon lined. They never need greased or cleaned, nothing can get inside of the bearing area to effect it, they come that way directly from the MFG.
I have had my set on my truck for going on 5-6 years now..... i forget.... but anyways, all i ever do is a couple times a year, is whipe the up with a rag and some wd40. They really dont accumulate that much dirt.
