Rear Rumble

I drive a '04 F-350 longbed and recently have been experiencing a rumble in the 25 to 35 mph range in the rear. I've checked most bolts (I think ) and pulled my bed liner out to check for a rock or something rattling around and have not found a solution. From what I can tell it is on the driver side and behind the cab. Any thoughts?

Hmmm...You gotta love these guessing games for a noise that you can't hear or a vibration you can't feel. Just throwing this out there, but I would start by looking at U-joints. It's quick and easy to check and somewhat common. While you are there check the carrier bearing on the "center" of the driveshaft (I think you have one). Then I think I would start checking wheel bearings. Good luck!

Check the vibration dampener on the drive shaft. Its a circle thing on the drive shaft closer to the pumpkin. see if that is loose

yeah i get a vib/rumble at 40-43 mph, due to the carrier bearing. (center loop around the two piece driveshafts on long beds). i'm trying to put mine off till tax returns to change. (and my powersteering gearbox is bad again, imagine that.)

later,
