I like to do mine every 500 Mike's or once a year. I always grease them when they're brand new.
I bought that special tool for greasing so you don't have to tear everything apart, takes me just over an hr to do 4 wheels
I trail ride with creek and river crossings etc. I always get water coming out of bearings when I do 2 x's a year.
Could imagine if swamping all the time should be done more often if you don't want to always be doing bearings
