Engine/Transmission (1998.5 - 2002) Fan Hub Bearing Screaming

[CrewCabDiesel]

Ok did some searching and it seems that I can order a bearing, and not the entire assembly? I found a NSK part # BD35-12AT12DDU801 but I can not find anyone that has the bearing. Is this the correct part #? Also what is involved in replacing the bearing, never replaced one before.

Thanks

Kyle
