just asking....what are you looking for or listening for, when checking your wheel bearings - as i think one of mine is on the way out.   MJR      if your wheel bearing is on its way out you will hear a 'droning' sound as you are driving  if you are getting this, jack the car up  so wheels  are off the floor(not being patronising) and  hold the wheels at top and bottom and se if there is any  movement repeat on all 4. if you find movement try to tighten if already tight replace it/them hope this helps Biscuit
