Very Strange sound from truck when coasting.
 

Suddenly for about the past month my truck has been a lot louder, almost as if I have bigger tires and lift(which I dont).

Here is a video I took of the sound. *It gets its loudest starting at 54MPH and continues as I slow down**


Anyone know what thsi is? tires are in good shape and balanced. Rides well also
Thanks!

No link to video???


Have you checked your front axle for oil??

It was my rear wheel rotor. The dust shield plate was rusted and was rubbing.
