Driving back home from a weekend at the parents house and almost a quarter mile from the house when this started (attached some videos). I pulled over as soon as it started but I couldnt see anything dragging under the car or anything loose. It only does it when im going in a straight line and off the accelerator. During acceleration it doesnt make the noise at all. While idling it doesnt make the sound at all either. Any of you recognize the sound? It just happened last night and I work all day until Wednesday so I wont be able to get under it until then to take a proper look. Thanks for looking though!

 

Update. I called off work and went under it. Lifted. Got under it and everything looked fine. I thought maybe behind the wheel. Only then did i realize that i was missing one lug. The entire stud is missing. And the rest of the lugs were loose. Very loose. I took them off by hand. Im guessing the wheel was wobbly and hitting the brake shroud metal thing behind the rotor and making the ping. Put the lugs back on and drove it and everything is fine. Always check the basics kids. Im just glad and happy that wheel didnt fly off while I was on the highway.

 

Torque all the lug nuts

 

thanks for coming back and updating us!
