Highway rumbling noise
I have a 2000 Excursion 7.3. I am having a weird vibration noise which only occurs at 52-55mph and up, most often at light to no throttle. When it occurs you can often throttle it more to get rid of the noise. It is like a rumble strip noise.
I have already replaced both stub shafts, all front seals, both wheel bearings, e.t.c, the whole front end. All u-joints are new as well.
I was thinking it might be the rear driveshaft angle (but didn't have any problems before), or the torque converter.
