The service manual has a very specific step by step process for adjusting both the tension and tracking of the belt. From reading the experiences here on the forums and on my own XCT bikes, a bird chirping/squeaking noise is usually an indication of a belt which is too loose not too tight.
I have alligned belts on two XCT bikes. The first time took me forever but the second time was a piece of cake due to a trick I learned. Loosen the axle nut but not completely. Keep a small amount of tension on this nut so that it takes a fair amount of force to move the axle forward or backward. After every slight turn of the adjustment nuts, get on the side of the bike and make sure the axle is as forward as possible on both sides (that is, make sure both adjustment nuts are up against their stops). Only then should you spin the wheel to examine the tracking of the belt. Much of this may sound cryptic but it will all become clear when you read the service manual instructions for how to adjust belt tension and alignment. Hope this helps.
