I am in the process of replacing my front calipers, rotors, bearings and struts.

When I took the rotors off, there was not in inner bearing, only the racers/seal. The outer bearing actually wasn’t that bad looking.

Do I need to add inner bearings to the new rotors I am putting on?
Also, the new rotors do not have the racers installed. Do the racers go into the rotor with the curved edge down or up?

 

The inner bearing is stuck behind the seal. If you pop the seal out, then the bearing should come out.

The outer races for both bearings press into rotor. Most new rotors come with new races already installed. But if they aren’t there already, the new bearing set will have them loose and you can just tap them in with a hammer and ideally a race driver, but an old race works too.
