Couple ways.
1 way is to reach the speed that you can hear the noise and in a "safe" environment. Sway the car left and right. Turning left loads the right side, turning right loads the left side. You are looking for the noise to get louder one direction or the other. Say you pitch the car left and it gets louder, you have isolated the problem to the right side.
NOW - I have had vehicles get noisy 1 way, but turn out to have a bad bearing on the unloaded side. With that being said the BEST way to verify is to put it in the air with all 4 wheels up. Put the thing in drive. turn the traction control off and have someone accelerate to about 25-35 mph. Take a screwdriver or stethoscope and place it on the back side of the hub and listen. One side should be quiet and smooth, the other will be noisy/grumbly/pulsating noise. That's your bad bearing.
Fronts are the most common on those, they are not hard to change.
Wheel off, Caliper bracket/caliper/rotor off, axle nut off, 3 bolts on the back holding the bearing/hub assy. , disconnect abs wire, hit with hammer a couple times if your lucky it will just pop right out.
