So I bought new rotors and also new wheel bearings well I was at it because they are in the hub. However I noticed on my old ones the inner bearing has a rubber o ring in the outside. And either the new wheel bearing or new rotor have that. Is this a problem? Or are there orings that come separately I'm supposed to buy?

 

they are bearing seals, they are sold separately. Pry the old ones out and gently tap the new ones in. Get the more expensive ones, they have a higher quality of rubber. You can see and feel the difference between the good ones and the cheap ones.

 

Upon messing with it I came to realize that. Thank you

 

Another question. I noticed my old rotors dident have a rave on the inner bearing just the bearing and the dust deal. Is that normal? Or do I use the race that comes with the bearing? Or is that only for the LE1 package

 

The outer races are pressed in. USE THE NEW OUTER RACES!!! Best thing is to take them to a machine shop to have the old races pressed out and the new ones pressed in.

 

no need for a machine shop or any fancy tools to change the bearing races in the rotor: just pound the old races out with a brass punch, and pound the new ones back in with the same punch... pound them straight in by working your way around the race, and keep going until you feel them seat tightly into the bottom of the bore in the hub.
it's not hard to do, you just need to make sure everything and they were nice enough to leave a little groove in the rotor housing so that the punch can push against the seat when pounding it out. you might need to clean out the grease to see it, but it's there.

this style of bearing was the norm for almost everything from the 1940's to the late 80's and changing them was a regular maintenance item. i learned how to do it by watching my grandpa, who learned how to do it when he was an aircraft mechanic for the Army Air Force during WW2. he could pound out an old race and have a new race seated in about a minute..

 

You can always by the new rotors with the races already installed.
