2008 Buick Lucerne pulls to right

replaced right front wheel bearing and car still pulls to the right

Rotate the tires and see if the pull goes away, most pulls are caused by tires.

Be honest now, tell us if you hit a curb on the right side of the car. If you did, that would cause the bearing to fail AND cause the car to pull to the right because you bent something. If you DID hit something, the car needs to be carefully inspected so the damage can be repaired before the pull will stop.
