Strange wheel sound

[lahalte]

I have been having a similar problem for the past year.I have posted with no luck.I have a sound coming from the front passenger area.It is like a hummm.My mecanic looked at it, drove it and can't figure out what is wrong.All seems tight.When I accelerate and turn right I hear it.If I don't accelerate and turn right I don't hear it.I will hear it on straight line when I cruise around 45.If I lift my foot off the gas gently it stops to return again at cruise.If I press the brake without removing my foot off the gas it stays.I have no idea.I thought maybe in the gas vent.But I put a tape on it and it still does it.Maybe the bearing but it does not get worse and not all the time.???????Good luck
