Lately I have had what sounds like a lot of road noise coming from the front passenger tire. I have looked at the tire, doesn't appear to have any uneven or odd tire wear, and my alignment though not perfect, isn't that bad. If I turn left or anytime weight shifts that way the noise goes away completely. Any suggestions for what it could be? Not seeing anything odd on the tire, I want to assume its a bearing, but before I go and buy parts id like to hear other thoughts.
