Front Wheel Bearings?

ok yes i searched, read, reviewed, and still cant find what i need so here goes:
redoing my front pads, rotors, rebuilding my calipers, and front wheel bearings, and nothing is stumping me except for my bearings, do they need to be pressed on/off?
the new bearings i have are from AUB Bearings, the new rotors are just blanks but when i removed the old rotors it appears that there is no way to remove the old bearing, as if it is pressed on, and the new rotors dont come with any pressed in...ill try and get pics up in a little while to illustrate what im really trying to say...

are the races the part that sit inside the rotor? those are what i cant get out...ill just post pictures later on tonight when i get home...argh.

yes the races are pressed into the rotor, you need to pound them out with a hammer and brass punch if your new bearings don't have new races with them

Since you have new rotors and new bearings, there's no need to pop the old bearing races out.

You will need a seal driver tool to put the new bearing races in the rotors.
Something like this but I'm sure you could pick something up locally for much less.

For the record, the last time I did this I used the old races to press in the new ones. Worked great...

This is an easy proccess.

When you buy new bearings you will always get new races with them. If for some reason they are not supplied in the same package, return them. Since you have new rotors and new bearings then there is no need to re-use anything. Take a punch and a hammer and pound the races into the rotor. You want to start them in evenly and move the punch around the race as you tap it in with medium to light force. When the race is seated you will hear a different sound when striking the punch. That is the race bottoming out on the seat inside the rotor. Make sure you grease everything well, and clean the rotors with brake cleaner before installation.

If you have to reuse your bearings then you simply flip the rotor over and use the punch and hammer to work the race out the other side, using the same method.

Good luck.

Just to clarify what I said earlier: Remove the old race from the old rotor, then lay that on top of the new race. That way, you pound on the old race, which drives the new race into position. This helps to avoid damage to the new races. I usually lay a block of wood over the old race before I start pounding on it. Works great, and eliminates the need for any special tools...
