i recently started to hear this noise that sounds similar to a bad wheel bearing, but its not very loud yet.. i asked my friend and they told me that i could be that my tires need to be rotated since i replaced the bearing almost a year ago.. well.. is there a way to find out for sure which bearing it is?? or if i just need to rotate my tires??
thanks

 

So you replaced it about a year ago and you believe that its already bad, or I guess that it could be one of the other ones that you did not replace?

How to tell which one:
-In a left turn and sound gets louder=passenger side
-In a right turn and sound gets louder=driver side

Thats how I diagnosed mine atleast.

 

Jack up the car and shake the wheel like Away from the car then towards the car and if the wheel wobbles then the bearing is bad
