When should the front wheel bearings be serviced? on 2009 Pontiac Vibe

I checked the front brake pads and they've got a ways to go. Ceramic pads are great. There is very little dust.

There is no service interval for replacing wheel bearings on your vehicle. They are sealed bearings. They will begin to make noise when they are bad.
Thanks for the info. The "old school" was to re-pack. I'm sure they last longer now.
