I was just bout to post the same thing but mine also does it when rolling but not in gear but also giving it gas to hear it. I was just gonna ask wat should I do to figure out if its a spun bearing or a rod knock dis is my first time problem like dis. I thought it was a cv axle cuz mine makes almost that same sound as an axle goin bad but it does when I'm roilling, driving, accelrating, even turning, anything between 1500-2500 rpms n it has to be hot. thanx fo info.
