The alternator is run of a completely separate belt. I think A/C is also run off a third belt but is not driven directly by the crank pulley.
Its a one piece bearing so it all needs to be replaced. I actually went to advanced bearings in Blacktown and they had ones for hyundais, mitsubishis and everything except for toyota. And they were 40 bucks! Anyway I'll give these fellas a try thanks for your help.
