Think you'll need to recheck what's what with the bearing/hubs you've worked on recently - pretty likely you've disturbed something with the wheel speed sensor I'd say.

When you start the car it could well decide all is ok but then once you're driving and it's not getting signal from one or more sensors it'll throw up a fault as you see once driving off.
