The resonating/humming problem at 60 - 65 mph I was having has been solved by two new bearings. This morning (about 40 degrees cold) when I pulled out of my driveway I still heard "clunk, clunk, clunk" from the drivetrain. As before, within a couple of miles & everything warmed up it goes away. It's not struts or suspension bushings because the road surface has nothing to do with it nor does turning the wheels affect it. Before I had the bearings done a shop was suspecting the trans or diff. which perform just fine. Anyone have any ideas?
