I put my truck up on stands and found that the rear end was making all the
noise. I set the e-brake to apply slight pressure to the wheels so it would
be more like a real world test. My brother brought it up to about 45mph,
and I took a stethoscope with a bolt in the end of it. Placed it on the rear
end and isolated the sound....
