Aside from tire wear, a visual inspection might not reveal much if the underlying problem is in an axle, bearing, or suspension component.
With the vehicle secured on stands but before you remove the wheel, grab the tire with both hands at the 12/6 o'clock positions and try to rock it to see if there is any play; repeat at the 9/3 o'clock positions. Smart money's probably on a bearing.
While you're down there, it wouldn't hurt to check the tie-rod play by grabbing it, and the balljoints with a 2x4 for leverage.
