Wheel bearings, if installed and maintained properly, have very little chance of failing. From my experience, bearing failures have occurred from bearings that are tightened too tight or haven't seen fresh grease in years.
This is very, very true. OTOH, more than a few millions of miles driven, much in equipment others thought to old to make a profit. Other than a flat tire I can't think of any breakdown where I had all the parts and equipment with me to solve the problem. For my camper, I will carry everything I need to fix anything that would keep me from getting it home.
