My 2000 f150 5.4 does the same thing at start up. Was told it was common for them. Didn't do it at high speed and warmed up though.
Mine has developed the rattle at startup that is associated with the back bolts on the exhaust manifold breaking which is a common problem for the 5.4. Once it get warm, the manifold expands and the leakage and noise quits. Haven't got around to looking at it or fixing it yet. Have to pull the fender wells to even look at it.
I'd probably start with a mechanics stethoscope or homemade one to ID a particular bearing on the alternator, A/C engaged and not engaged, idler pulley, manifold, hoses, etc. Might even have a cracked or bad vacuum hose somewhere.
