I'm sorry for your troubles.
The wheel bearing should be covered under warranty. I would fight with the dealer. When installing springs you do not touch the bearing. It is enclosed in the hub. Bad bearing has nothing to do with the springs you installed on your car.
Also a bad bearing should not cause a CEL. Usually bad bearings are only heard and felt. You usually get a humming sound and vibration of some sort when a bearing has failed. I am not sure how the abs/dsc senors can determine a bad bearing??
