Hello and thank you for your post. I am a master certified GM tech, with 15 years Saturn experience,and can help you to resolve your issue.

if you put the vehicle up in the air (all 4 tires off the ground) and drive it at the speed that makes the noise you can use either a long screwdriver pressed to your ear or a mechanics stethoscope and listen to the rear differential, rear hub bearings and driveshaft center support bearing

(if it is awd)

if this is 2wd than you must spin the rear tires by hand while listening

one side will be significantly noiser than the other

unless this is a noisy tire this should lead you the noise

when listening to teh rear bearings, place the listening device on the bolts that secure the bearing to teh hub

you need to come in from behind

they are 13mm head bolts

4 of them

any one will do

that is where a noisy bearing will sound the loudest

hope this helps

(bearings are very common to go bad on these)
