Can anyone help me to identify this intermittent metal sound ...almost as if someone was sticking a card in a metal fan or spinning spoke. i searched youtube & found a guy with exact same sound. It happens when driving intermittently. I have a video of exactly what happens ...the sound anyway.. its on youtube. I will provide the link. block out the wind. its that other sound. 1st link Nissan Altima 2.5s making weird metal noise" on YouTube https://youtu.be/jirs67-F_Yo
the 2nd link is a pic with the sounds. please help if u can. https://youtu.be/eiGfK4yuqLQ
thank you in advance for your help. I have no one to go to for help so will try to learn from youtube if it can be diagnosed.
