Once properly packed they can go for a very long time.
In my case, since the stabilizer jacks are capable of lifting the wheels off the ground it is easy for me to check for excessive play or noise so I do that a couple of times a year. I usually repack mine before a "long" trip, but it is really not necessary, probably every couple of years. Just check closely for wear when they are cleaned up during repacking and check to make sure nothing is overheating if you stop along the way.
Back in another lifetime when I actually did brake jobs and front end alignments for a living I came to the conclusion that the number one major cause of wheel bearing failure was would be mechanics who would over-tighten the castle nut when doing their own brakes or repacking their own wheel bearings.
Of course I can never resist the chance to mention the story of when my step brother decided to repack the wheel bearings on his 57 Chevy. Since I was overseas he did not figure that I would miss the small can of "bearing grease" that he found in the old barn where such work was usually done. The "grease" that he found was in a green can with shamrock on the lid. Of course that is the trademark for Clover valve grinding compound (an abrasive). Needless to say his bearings did not last very long after that repacking.
