Don't discount the possibility that the right side drive axle is
binding once it has been in motion for some time.  The most likely
cause of brake-off, power/coast vibration on a car such as this is a
bad inner joint on the longer CV axle.  Your car's longer CV axle
happens to be on the right side.  There are too many possibilities to
list so I'm just mentioning something that it could *likely* be.  Even
the outboard joint on the right side could be binding intermittently
and causing the higher right wheel temp.  Proper diagnosis from a
competent mechanic charging fair prices would be your best course of
action.
