i had to take off steering knuckle to remove what's looks to be original hub on a '05 when I used a pickle fork to pop the lower ball joint (which looked original aswell) I noticed the clearish grease starting to leak I don't see any damage to boot so I don't know if I wrecked it but I was thinking of replacing just in case, my question is are they pressed in or should it pop out easy enough once I drill out the rivets, I don't want drill out if I'm not going to be able to remove it from control arm.
