Well if you put the rubber insolators back holding the rack, that part should be ok. The ball and socket ends of the rack must be tight, but enough to allow free movement. Could be upper and lower ball joint, then again it could be a wheel or tire way out of balance.
Also make sure the tie rod ends are on tight and that the wheel bearings don't have any real play in them. This doesn't sound like your problem, but if it is under braking, then the rotor could be warped.
Let us know.
