03 elantra front bearing
 

Has anyone done a replacement on these? How hard is it ? I've done them on other cars but never a hyundai

This type of hub bearing is designed to pressed out at the machine shop. It is, however, possible to do it in your driveway by driving out the bearing with a hammer and punch. It's not too easy or clean, but it does work. Remove the hub snap ring, pull out the hub, beat the bearing out, beat the new one in.
