check the torque on the axle nut, and if the torque isn't to spec, buy a new axle nut and torque it properly.

check the heatshields to see if anything is loose

next time the car is in the air grab the tire and try to 'twist' it (pull out with one hand and push in with the other hand) if the tire moves the wheel bearing is going bad

also with the balljoints sometimes it is very subtle when they are just starting to go bad. when the front right ball joint got damaged on my sube i would only notice under very specific conditions (ie slow left turn pulling into a slightly inclined driveway)

good luck!
