1st thing is DO NOT assume that it's your wheel bearings. Jack up the car in the front and put it on jack stands. Go to the driver side tire and grab the tire at 12 and 6 o'clock positions and in an up and down motion (like pulling the top of the tire to you and pushing the bottom away) rapidly try to shake the tire. Now try the 3 and 9 o'clock positions. Try to move the tire from side to side as if the wheels were being turned by the steering wheel. Any movement up and down is more than likely your wheel bearings, any movement side to side is usually the tie rod( outer or inner) Have a 2nd person see if they can hear or see anything from behind the wheel moving as you do this.
Also grab the bottom of the tire and try to lift as in simulating hitting a bump. Have the 2nd person see if there is any movement at the top near the strut tower bolts. Look at your tire tread. run your hands across it following the tread and back again. If the tread is "grabby" in one direction more than the other this called a saw tooth edge and usually results from the shocks being faulty. If the tread is worn more on the inside 1/2 of the tire it's an alignment issue. Even if you just had one done, if the tires are shot that could pull the car back out of alignment. More tread on the outsides than in the middle is too much air and more on the inside half than on the outer edges is too little air. Proper air requirements are posted on the door tag located on the door frame on the driver side NOT the listing on the tire.
I'm sure there is ALOT more that I could list here as to what your tires can tell you and how to check other suspension items but that should get you started for the time being.
