Hi all I have a 2006 Quest base with 45k miles and for a month the increasing noise that I was getting I THOUGHT was a tire that was cupping, as it had kind of a "whump whump whump" sound to it... I even replaced the tires even though all they had was REALLY light feathering... but the noise remained. I

It's increased now (happens even when coasting in neutral btw).. could it be a hub bearing? It's somewhere in the front, no real shake, but I can change the pitch with hard yaw to the left... at which point it almost completely goes away.

I guess the reason I ask is that I always thought when a hub went bad, it was a continual grind sound or hum (that changes pitch with lean) but it was CONTINUAL, not like this whump-whump-whump sound. But I'm getting more convinced its the LF hub assy. Could I be right? Any input as soon as possible would help!
