Like the title says, I've got this annoying sound coming from the passenger side of the truck. It's not all the time, and it seems like I hear it more frequently when I'm driving on the highway, usually starting around 75mph or so. However, I do hear it on back roads occasionally too, typically around 50mph. Whatever it is, it's driving me nuts. It doesn't seem like it's suspension related, because even though it CAN be triggered by by potholes or frost heaves (of which we have many!) it isn't always, and often it starts without hitting any bumps. Ambient temperature doesn't seem to affect it-it may be slightly more frequent when it's exceptionally cold out?
At any rate, I'd like to get rid of it.
I've got a 2010 Access Cab 4.0L/Auto w/stock suspension and 265 Duratrac's, if it helps.
