Interesting to me is the fact we're all still dealing with this nonsense. :M I've owned so many vehicles over many decades I can't even remember them all, yet I don't recall ever having to replace or even service the wheel bearings ... until recently. For the first time in my life a wheel bearing on the front driver's side of our 11 yr old Chevy Avalanche went south and had to be replaced ... first time this has ever happened to me. Surely by now the RV industry could install bearings that don't need yearly repacking and under normal circumstances won't fail during the lifetime of the trailer. :S
