Noises and vibrations are difficult to diagnose without experiencing them 
first hand.  Vibrations at higher speeds are generally caused by tire 
problems, and they can go away if there is moisture in the tires that
melts 
as the tires warm up or if there is a flat spot in one or more of the
tires. 
It is also possible that there is a problem in the transmission or a
binding 
driveshaft or axle shaft that loosens up as it warms up.
