I definitely like to feel my hubs after driving too. Trucks and trailers... like you said it can be your first alert to trouble. Well by sheer luck my second bearing arrived today and it is a barrel type so I cleaned it up, packed and installed it. After cleaning the nos bearing it was immaculate! So, my truck rides again! Wife and I are going to take a short cruise in it tomorrow then Sunday will be it's first long trip... possibly the farthest the truck has ever been driven in a day. Off to see my parents for Easter then home the same day! I know they'll get a kick out of seeing it run.
