I believe that has a lot to do with where and how you drive. Dusty, Through a lot of water, mud, how many miles per year, etc.
If you had an older car you should repack your wheel bearings about once a year. Now you cant do that. I try to do my trailer bearings about once a year.
So I would think at least once a year or more frequently depending on above. I grease all my fittings about once a month and whenever I go on a long ride. Wheel bearings 2x per year. It gets easier the more you do it. Also gives me a chance to go over the whole machine to see what else is need of attention. As an example I did my buddies quad this spring and found his rear brake was loose. Interestingly enough was he just had it in the shop for a complete go over/tune up. This shows that they didnt look at that, or they did and didnt do the job properly either way, need to be tightened.
