   My 1982 Chevy K10 came with those hubs and supposed shift on the fly.   
   Hardcore four-wheelers replaced them early on. Had a tendency to self   
   destruct when trying to rock your way out of being stuck...   
      
   I eventually replaced them with manual hubs too. Didn't trust them to   
   release and didn't want to mess around cleaning, re-lubing them. Spec   
   called for a special grease. A nice benefit was getting pseudo 2-Low.   
   Low range was really nice for climbing on ramps, moving trailers around   
   and just idling about without drive train wrap-up.   
      
   Replaced it with a used 2013 Chevy Impala. I try really hard to stay   
   off the roads when they're salted. Wait for them to be clear and less   
   salty before heading out...
