Hey guys we bought our first expedition, 08' Eddie Bauer, about a month ago. Everything has been good so far but this weekend I want to try and tracking down a slight howl that is coming from the drivers side front. I haven ruled anything out yet, first thing I want to look at is the tire of course, but are there any other common items to check out? I am familiar with the bearing/ball joint/ u-joint issues on ford superdutys but this is new ground for me. Thanks for the help, Adam.
