Wheel bearings
What is so different with RV wheel bearings that they have to be packed at least every year or two. My truck and car does not require this yearly maintenance, why does the RV axles??

I changed out my Chinese bearings and seals for Timkens and CR's after four years and am using a quality anti-corrosion Hi-temp lube. Living in PA, I'm stuck with the state law which dictates an "inspection" every year. They're required to pull two wheels to check brakes and magnets, etc. The two that they pull ( I go to the same shop and have them alternate yearly), I always re-do just for peace of mind. Last time, they loaded up the bearing with some other grease which I have no clue what it was. The end result for me is I get to do two axles every year and the bearings never go more than two years between checking and re-lubing. I feel this is more than adequate and keeps me from become an obsessive RV owner. I didn't buy a trailer to work on it, I bought it to go camping. Go with whatever your peace of mind will allow.
