i put my number on tie rods since you said it will pull from side to side, wheel bearings make a roaring noise plus nissans are sealed units and barely ever need replacement, jack up the front end and shake the tire back and forth like you're making it turn right and left, shake it like that and if you feel any play then it's your tie rods. if you feel a little play then as you're shaking look at the outer tie rod and see if that is where the looseness is, if it's firm but there's still play in there then it's your inner tie rods. but all in all you should still balance the tires again while you're at it.
