Double check and make sure your routing is correct. I'm unsure about the 7.3 but many trucks you can route wrong.

^^^^^ Just eye-balling the pulleys from either side (fender) of the engine might identify a pulley that's out of alignment, either one that's too far forward / too far aft, or one that's not in the same "plane" (at a bad angle) as the other pulleys.
In particular, wind up the tensioner and unwind it again, and watch the pulley as you do so. Even if the spring is tight, if there's wear in the body of the tensioner, you'll notice that the angle of the pulley changes as the spring unwinds and it tensions the belt. That can chew up a belt.
