Lift each of the 4 wheels one at a time and grab it at 9 and 3 o'clock and "pull-push" with some force. See if there is any play. It may be wheel bearing or tie rods (on front wheels). Another test if you can lift the car, grab the inner left CV joint near the transmission and see if it wobbles inside the transmission. This would be a carrier bearing. Also may keep in mind that not all garages balance the wheels correctly, may try another place. A unballanced rear wheel will cause chassis vibrations, front ones steering vibrations. May be a combination of the two, of course. For the hub flanges, if there is any slight bent non visible to the eye - usually if someone hit with a hammer trying to remove the wheel bearing, the wheel lugs will loosen up while driving, so you will know it.

Side note, I had a situation when there was rust on the tire belt (from an old rim), a mechanic cleaned this rust which dropped inside the tire, the tire was then mounted with the rust bits inside - could hear this by rolling the tire on the ground. It was impossible to balance on an electronic machine
