Your warranty covers defects in materials and workmanship. As long as the unit has not been ABUSED (dropped and dented, spilled water, run over by a Truck, etc) the Genius Bar at an Apple Store will repair it for you, under warranty. It is their decision how to accomplish the repair.
In general, Apple does not want you to open your Mac and make repairs yourself, so they are unlikely to send you parts. They have a Mail-in Service In some areas, where they will send a courier to pick up your MacBook for Repair.
