They shouldn't be going bad in a 99 civ, but I've done wheel bearings under warr. a couple times at the dealership. They will usually last a good 5-10 yrs. In my experience. on hondas at least. Napa is okay for parts on an old chevy, but i'd never put non-honda parts on my hondas. That's just me. If you like going there or whatever cool, but don't say I didn't warn you.
