While driving this truck a intermittent sound comes from underneath the vehicle. Not sure if from the front or rear of the vehicle. It sounds like you would be dragging something on the pavement. Nothing appears to be loose underneath and I jacked up the front end and bearings seem to be fine. The noise is related to motion, as you slow down the noise also does. There is 225,000 kms on truck. Has anyone else experienced this?
Thanks in advance, Freddy

 

How are the brakes and rotors. Check to make certain you don't have a debris cover bent on the wheel assembly.
